Stage in the Lifespan an Example by
Stage in the Lifespan by Expert Lilliana | 23 Dec 2016 Young adulthood has become an increasingly difficult time in the lives of humans that find themselves too old to be considered children and too young to be taken seriously as adults. Tweens, teens, and college age people are no longer completely dismissed by culture, as the purchasing power of children ages nine to fourteen has increased to become a force to be reckoned with and society sometimes seems to cater to their sensibilities. With so much information continuously coming at them through the internet, the television, magazines and movies, young adults often have trouble finding the path for which they are best suited, and many find themselves victimized by sexually transmitted diseases and crime. Because it is such a confusing time in the life of humans, young adults simply try to learn about adulthood while enjoying the last carefree days of youth. Need essay sample on "Stage in the Lifespan" topic? We will write a custom essay sample specifically for you Proceed The first thing that must be addressed when discussing young adults is their burgeoning sexuality. Biologically, young adults are either reaching or already in their sexual maturity, when hormones are raging often beyond their control. The question of teenage sexual activity is one that may be misleading, due in large part to the evolution of society and its more relaxed attitude toward sex. Less than a century ago, it was routine for teenagers to get married and begin families fresh out of high school. However, now that education is considered something that requires many years if a person expects to succeed in society, the cycle of marriage, sex, and starting families has also been postponed until much later in life. So, when teens reach biological maturity and begin to feel sexual urges, they experiment and often subject themselves to terrible consequences such as unwanted pregnancy and sexually transmitted disease. The overwhelming and often tragic figures that explore teenage sexuality are hard to ignore. Compared to older adults, adolescents between the ages of ten and nineteen are at higher risk for acquiring STDs for a number of reasons, including limited access to preventive and regular health care and physiologically increased susceptibility to infection (Kaiser Family Foundation, 2005). And among these young sexually active teens, minorities and teenage girls have been particularly hard hit by HIV/AIDS. Young African Americans represented 65% of AIDS cases reported among 13-19 year olds in 2002, suggesting that they are less likely to practice safe sex than white teenagers. Latino teens represented 20% of new AIDS cases, and in 2002, girls represented 51% of HIV cases reported among 13-19 year olds, compared to 30% of cases reported among people over age 25 that same year (Kaiser Family Foundation, 2005). These figures suggest a problem that is difficult to curb. Current sexual education is not nearly adequate enough to deal with the trends. Most teenagers are skeptical by nature, as well as inpidualistic when it comes to being told what to do, and the standard line of abstaining is not practical and does not work. Abstinence vows may work for some teens, but are largely nothing more than lip service. Teens have simply become more adept at avoiding pregnancy and retaining their abstinence, including abandoning the practice of vaginal sex and opting for oral or anal sex. Many teenage girls feel that unless the sex they have is vaginal, they are still technically virgins. This goes to show that the moral and religious leaders that push for sexual education are merely confusing the issue rather than illuminating it. While some teens are at higher risk for sexual activity, including those that have been abused or use drugs and alcohol, all teens experience raging hormones and sexual impulses. It is a mistake to expect a denial of their human impulses, so an intelligent compromise must be reached regarding teenage sex. Whether this involves more sexual education from a young age that is informative rather than dogmatic, or changing society to allow teens to pursue valuable relationships instead of merely focusing on school and future careers, teenage sexuality must be addressed and dealt with in an honest and effective way. In addition to sex, teens also experience many difficulties with alcohol. Debate continues in the medical community as to whether alcoholism is a physical or psychological disease, but the connection between alcohol and mental health is undeniable. Because of the cavalier attitude the United States takes towards alcohol consumption, the stresses that come with everyday life in the fast-paced modern world that encourage chemical solutions, and the overwhelming statistical evidence suggesting that alcoholism is a national epidemic, alcohol abuse resembles a mass mental health problem that can only be curbed through therapy and education. And, this problem is intensified when it concerns teenagers. While alcohol consumption is illegal for teenagers, that fact does little to curb teenage drinking. Teens drink whether authorities and parents like it or not, and the problem leads to many problems beyond just breaking the law, and can significantly impact their education and their future. As a highly powerful drug, alcohol may not receive the professional medical endorsement as some pharmaceuticals, nor contain the powerful anesthetizing characteristics of many illegal narcotics, but its cost and ease of availability makes it a popular drug for millions of American teens. According to a survey released by the Texas Commission on Alcohol and Drug Abuse, it was found that by the time the states teenagers reach their senior year in high school, more than 80% of them admit to having some experience with alcohol (Westbrook, 2007). The same study also found that most of the students consider it easy to get alcohol. The fact that Texas is a zero tolerance state for underage drinking exemplifies the futility of current methods of trying to keep teenagers away from alcohol, which usually include nothing more than a repetitive mandate telling them not to drink. It would seem that the only remedy to alcohol abuse in society is through better education and programs designed to counter the overwhelmingly supportive stance taken on alcohol by current social organizations. In addition to providing such information, prevention programs should teach inpiduals about the role that alcohol expectancies play in regard to heavy and abusive drinking, and help restructure expectancies among abusive or potentially abusive drinkers (Frone, et al., 1993, p. 556). By convincing more people that alcohol cannot truly eradicate or alleviate their problems, and in fact make their problems worse, mental health professionals stand a better chance of discouraging inpiduals from participating in future alcohol abuse. However, unlike many health issues, professionals must compete with an industry that spends billions of dollars a year to attract consumers. Alcohol abuse has been and continues to be a mental health epidemic in the United States, encouraged by a society largely accepting of alcohol use and the many stresses of school and home life that drive people to seek alcoholic therapy. Alcoholism can even impact the aspirations of a young adult, like John. Even though John was a freshman, he was a starter on the varsity volleyball and basketball teams. He was offended when he failed to make the varsity football team, but while he thought he should have made the varsity team as a freshman, the coach explained how all freshmen had to play on the freshman team. John proved the coach wrong by midseason and was starting as a running back on varsity by the fifth game. John was one of the few freshmen in the state to make all-conference in three sports, and he even began to attract the attention of multiple colleges. Johns popularity in school grew with every athletic victory, and girls did not escape his attention. Soon, John was engaging in promiscuous sex and partying with the upperclassmen. While this did not seem to affect his performance on the playing field, as John had an equally impressive sophomore year, and continued to enjoy his success socially and athletically. However, when John was drinking with friends one weekend, he broke h is ankle in a drunk-driving accident. He had to drop out of football entirely his junior year because he could barely walk, let alone play. He had a huge cast on my ankle and had to walk with crutches for months. When volleyball and basketball began, he was still rehabbing my ankle and working with physical therapists to try to strengthen it enough to endure the stresses of continuous jumping. This made him miss considerable time, and his sophomore season was nothing like he had imagined the year before, and the scouts stopping showing up and calling. He continued to drink and party, though was also severely depressed. However, he continued conditioning, doing physical therapy, and he planned on making his senior year the one that would finally allow him to shine athletically and hopefully attract enough attention from colleges to get scholarships. However, John once again injured himself while drinking, this time breaking his wrist while on a dare. This in effect not only ended Johns athletic aspirations for his senior year, but also prevented him from getting into any college on a scholarship. Because John spent so much time playing sports and partying, Johns academics were anything but stellar, and college was difficult for him to get into. The last report on John was that he was living in the same town with his parents and had no job or aspirations, but still partied all the time with his friends. If it were not for alcohol early in Johns young adulthood, there is no telling how far he might have gotten, if only to get the chance to go to college and truly begin his education. The trials and tribulations of young adulthood are enough to deal with without being inundated by confusing messages that are constantly bombarding young adults. Sexual experimentation, youth drinking, and lost dreams of irresponsible teens are only the most extreme examples of young adult behavior. What cannot be discounted are the millions of young adults that are responsible and become upstanding and contributing members of society. The only difference between the young adults that do well in adulthood to those that do not is the quality of the education they receive. And, the education that young adults receive is the responsibility not only of themselves, but also the adults from which they learn. REFERENCES Frone, M. R., Russell, M., and Cooper, M. L.

History of Air Transport and Airport
History of Air Transport and Airport Introduction Transport economics mainly focus on the movement of goods and people over time and space. There are different modes of transport used to transport goods and people from one region to another. These include road transport, air transport, rail transport, sea and air transport.Advertising We will write a custom research paper sample on History of Air Transport and Airport specifically for you for only $16.05 $11/page Learn More All these modes have their advantages and disadvantages and the choice of one mode of transport depends on several factors such as speed, costs, convenience, and many other factors. In transport economics, the cost of transport is very important since it plays an important role in facilitation of trade. This topic analyses transport economics specifically on the area of air transport. History of Air Transport Among all the other modes of transport, air transport was among the last modes to be developed. Before the developmen t of air transport, the other modes of transport such as road and sea transport, which were developed many years ago, were used. In the ancient times before the discovery of modern modes of transport, people used to walk by foot from place to another implying that, even for people to exchange goods and services, they had to walk by foot from one market place to another. This mode of exchange was very cumbersome for many reasons. First, it was time consuming; secondly, the quantity of goods to be transported was very little and this phenomenon made it difficult to trade and the transport was so inconvenient. However, as the time went by, different modes of transport were developed which reduced the cost of transport. For instance, roads were developed and trucks could be used to transport goods from one region to another. Rail and water transport were developed and goods could now be transported over long distances. Development of rail and water transport made it possible for traders to exchange their goods from country or continent to another and this facilitated more trade and reduced costs of transportation. However, the development of these three modes of transport (road, rail, and sea) transport did not solve the problem of transport completely. A mode of transport that was faster and more convenient was required. This need led to the development of air transport in the early twentieth century.Advertising Looking for research paper on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Through innovation of airplane, trade was taken to another new level where goods could now be exchanged at faster rate than before. Air transport made it possible to transport goods and people from one region to another within few minutes. Perishable goods, which could not be exchanged before due to their nature, could now be transported from one region to another. Movement of goods and people was enhanced i n all parts of the globe. The cost of transport was also reduced in a large proportion by the development of the air transport. Since then, air transport has been developing with discovery of more advanced aircrafts, which has made transport of goods and people faster and more convenient. Development of Airport Discovery of aircrafts facilitated development of airports that act as the hubs of air transport. Airports have developed over the years as more advanced airplanes are developed. Airports have been developed in all the countries in the world. In developed countries, there are numerous airports in almost all the major towns to facilitate transportations of goods and services from one region to another. Global cities such as London, New York, Paris and many others that serve as the centre of international trade have developed large and modern airports over the last years to enhance transportation of people and goods in all the regions of the world. Airlines from different compa nies use these major airports as their centre to all the other routes in the world. Air transport and economic development The development of air transport over the years has transformed trade through increased movement of goods and passengers. Due to speed and convenience of the air transport, many businesses people carrying out international and domestic trade have opted for this mode of transport despite its high charges. According to Daley, air transport has made a positive contribution to the economy over the time (210). The graph below shows the relationship between economic growth and the volume of goods and passengers using air transport from 1950 to 2008. Source: The Geography of Transport SystemsAdvertising We will write a custom research paper sample on History of Air Transport and Airport specifically for you for only $16.05 $11/page Learn More Between 1950 and 2008, airfreight and air passengersââ¬â¢ traffic was growing faster than the worl d economic growth rate. This can be attributed to the capability of the air transport to reduce time and space which attracted more goods and people to this mode. Around 1960, there was congestion in the air transport traffic and air transport companies were looking for airplanes that could carry more passengers and goods. In 1970s, there was revolution in the air industry after development of large capacity airplanes, which could carry larger capacity and charge low prices. This increased global economic growth. As Xiaowen, Tae and Anming note, increased competition and efficiency has also increased demand of air transport (p.24). Thus, economic growth and air transport are closely related and development of air transport has increased global economic growth. Airport security Though the development of air transport has transformed world trade, it has come along with negatives effects that have seriously affected the lives of people. These negative effects include environmental poll ution, air accidents, increased illegal trafficking of goods and people among other problems. Over the past years, the issue of insecurity has become a major global challenge due to increased cases of crimes in aircraft and airports. Due to increased volume of people using air transport, airports have become potential targets for crimes such as terrorism and other kinds of crimes. Airport provides a large crowd that is concentrated on a small area, which makes it highly susceptible to terrorism attacks. Large global airlines are also targeted due to their carrying capacity of their aircraft. The 9/11 terrorist attack at the World Trade Centre headquarters in New York in 2002 represents one of the recent terrorism attack on aircrafts. Due to increased cases of terrorism attacks and especially after the 9/11 attack, airport, and aircraft security has become a very sensitive issue in the whole world. Strict measures have been put in air transport to prevent such occurrences in future. Lord indicates that, risk assessment in the airport security is necessary in all the airports (1). According to United States Government Accountability Office (GAO), report security scrutiny should also be done even in foreign airports and aircraft to prevent cases of terrorism (111). Techniques and various methods have been adopted in airports in the world to ensure that aircrafts and airports are protected from any potential attack. New techniques have been developed to screen both people and goods in the airport in the search for bombs and other explosives.Advertising Looking for research paper on business economics?

Operations Management for Competitive Advantage Essay
Operations Management for Competitive Advantage - Essay Example Amongst the numerous concepts and tools that can come under application for the problem related to the facility location and layout, centroid method came under consideration as the best applicable tool for the company Eldora (EDC) who were leading manufacturers of bicycle in the U.S. The highlighting issue of EDC illustrates the information that the manufacturing plant units did not come under relocation to other locations such as in Asian countries as this market was becoming the leader in the manufacturing industry especially due to its cheap labor. Because of a domestic strategy allied to the production of the bicycles, all the business processes of EDC remained to one location only. As an outcome of this decision, they came across several issues associated to the facility location; centroid methodology was the finest solution if adopted by EDC would resolve the concerned issue. This tool proves to be fruitful for the organization as it has numerous benefits that can aid the compa ny. The expected results of this method will lead them to reduced costs in their production due to cheap labor, having the prospect to penetrate into new market segmentation, competitive advantage over others as being present into a global marketplace. In addition, the manufacturing enterprise will also have the advantage from the environmental regulations in the local plant and will also develop and persuade the relationships with the local residents of that area, and will help in removing the cultural barriers between them and there are many more benefits that the organization can have from it. Background Information The organization that is under discussion in the thesis paper is Eldora Company (EDC), which is considerably one of the dominant, well-known and most popular businesses that manufacture and supply bicycles in the United States of America (Chase, 2006). Eldora experienced a boom in its sales and recognition in the marketplace since the last decade, as their lower price of the bicycles for a very long time gave them an edge over their competitors. With the increasing reputation, EDC became the market leader as it contributed to more than twenty-five percent of the bicycle sales of the United States. Eldora Companyââ¬â¢s business units were located at the same site and all the operational units and the corporate office shared one roof. EDC was a huge organization with numerous employees and workers; and they have come under division according to their capabilities, areas of expertise and skills (Chase, 2006). Through the joint venture with a company based in Europe, Eldora expanded its business into the European market as well. Eldora was an organization that encouraged and promoted the viewpoints, innovative ideas, and recommendations of their employees related to the mechanism of the bicycle that provides with additional features. The loyalty and dedication of the employees towards the company can come under limelight as information and awaren ess of most modern and recent fashion and approach was the key motive of the members of the staff (Chase, 2006). The principal motivation and influencing factor for the bicycle manufacturersââ¬â¢ repositioning of facility location to the Asian world was that this market was experiencing a boom of bicycle producers at a phenomenal and an unprecedented rate, which allowed them to have cheaper labor in comparison coupled with low distribution costs (Chase, 2006).

The topic will be in the instruction plus the attached file - Essay Example In the U.A.E, and indeed across the world, the problem should be tackled before the situation gets worse. Tackling the obesity issue effectively demands the appreciation of the root causes of the problem. Experts agree that the main factors behind rising obesity prevalence levels across the world are sedentary lifestyles (lifestyles devoid of exercise) and poor eating habits. In respect of eating habits, it is worth noting that the consumption of too much fatty, sugary, junk, and salty foods easily lead to obesity. To this effect, individuals should eat less of junk foods, consume more vegetables, and exercise more as ways of preventing and dealing with obesity. As a way of dealing with obesity in schools, the ministry of health plans to introduce physical exercise (P.E.) lessons as part of the school curriculum. By having three lessons of P.E. a week with each lesson taking 40 minutes, school children will become more active and burn excess fats in their bodies that would otherwise lead them to become obese. Secondly, the ministry plans to regulate the kinds of foods that children are given in school and those that are available in school canteens. The ministry will work toward ensuring that schools offer balanced diets and that canteens stock no junk foods. Cleland E.

The Isolation of Bacteria from Sewage water
The Isolation of Bacteria from Sewage water The Isolation of Bacteria from Sewage water for the decomposition of HDPE (High Density Polyethylene) plastic films Chapter I- Introduction BACKGROUND OF THE STUDY Plastic is lightweight, durable and impermeable. These qualities have made plastic a preferable material for society. But the abundant production of plastic due to the great demand of society means an excessive deal of disposal as well. The use of these lightweight, inexpensive materials are as single-use items that will go to the garbage dump within a year, where theyââ¬â¢ll persist for centuries. This imposes a threat to the health of people, animals, and the environment. Most plastic bags are made from polyethylene (PE) which is a polymer consisting of long chains of the monomer ethylene (Burd, 2008). A molecule of Polyethylene is made up of a long chain of carbon atoms with one hydrogen atom attached to each carbon atom. High Density Polyethylene (HDPE) is one kind of Polyethylene material that is used for making plastic products such as shopping bags, shampoo bottles, etc. (Freudenrich, Ph.D, 2011). HDPE plastic bags have a high melting point and tensile strength, making it difficult to be decomposed, which is a problem in maintaining the cleanliness of the environment. Wastewater comes from two major sources: human sewage and process waste from manufacturing industries. Waste water treatment involves containing naturally occurring bacteria and microbes at a high concentration in tanks to form active sludge. The bacteria in the sludge feed on the carbon molecules from the waste in order to grow, thus, cleansing the waste water (Davies B.Sc, Ph.D, 2005) Previous studies have also shown that plastics that end up in landfills degrade due to certain types of carbon-thriving bacterium that break down the plastic into simpler and safer forms such as water and alcohol. Since High Density Polyethylene plastic is basically made up of carbon molecules, and sewage water contains various bacterium that are used for wastewater treatments it can be concluded that certain bacterium in sewage water can be utilized in degrading HDPE plastic bags. GENERAL PROBLEM What is the effect of the isolated bacteria from the sewage water to the HDPE plastic in terms of weight? SUB PROBLEMS 1. How many types of decomposing bacteria can be found in the sewage water? 2. What would be the most effective decomposing bacteria for HDPE plastic that may be found in sewage water? 3. How much weight loss will HDPE plastic have with the help of these decomposing bacteria? OBJECTIVES 1. To identify and isolate the PE- degrading bacteria in sewage water. 2. To discover a way to utilize bacteria in decomposing plastic waste. 3. To identify strains of bacteria that is not considered as PE degrading bacteria SIGNIFICANCE OF THE STUDY This study shows the importance of the presence of bacteria in sewage water. It may not be the reason for people to avoid the contamination of bodies of water but it may be an assurance that HDPE (High Density Polyethylene) plastic films will degrade through the existence and exposure of cultured bacteria in sewage water. The strains of bacteria will be isolated and identified then will be used to decompose plastic and make sure that the strain of bacteria is the main cause for its degradation and weight loss. It is common knowledge to know that PE degrading bacteria are present in landfill but there are questions to people if PE degrading bacteria are consistently present in bodies of water, and if the strains of bacteria that inhabit water largely affect the decomposition of plastic films, these questions will be answered after the experimentation. The study can be more interesting if the resulting isolated bacteria are not described as PE degrading bacteria. It will be a new disco very because the identified bacteria will be considered as a new medium for decomposition. SCOPE AND LIMITATIONS In the said study, the researchers are focused in isolating bacteria and using it as a decomposer of HDPE (High Density Polyethylene) plastic bags. They are limited to utilizing samples from sewage water, with the assumption that it contains various kinds of microorganisms, as a source of the bacteria that they will need in decomposing the said plastic. The researchers are also limited to using High-density Polyethylene bags which is known for its high density and strong tensile strength. Furthermore, due to its high density, this kind of plastic is not easily decomposed making it as a problem in maintaining the cleanliness of the environment. Chapter II- Review of Related Literature Plastic Plastic is a lightweight, impermeable and durable material. It has many uses to society most commonly for packaging and storage. It is presented in a variety of ways depending on the mixture and the chemical bonds. The chemical bonds of plastic make it slow down the degrading process making the high production of this material harmful to the environment. It is harmful especially when it is not disposed properly. Most plastics have organic polymers. Most of these polymers have either chains of carbon dioxide alone or with oxygen, sulphur and or nitrogen. Polyethylene Polyethylene is the most common plastic used today. Approximately 80 million tons of it is produced yearly. Its main use is for packaging. It commonly has a long carbon chain with two hydrogen atoms attached to each carbon atom in the chain. It is chemically synthesized from ethylene, which is a compound usually made from petroleum or natural gas. HDPE When there are no long chains of polyethylene branching from the carbon atoms the polyethylene is now classified as linear polyethylene. It is more costly than LDPE but even though it is costly it is sturdier. Linear polyethylene is made by a procedure called Ziegler-Natta Polymerization. Water Water has the chemical equation H2O. It covers 71% of the earthââ¬â¢s surface. It is in liquid form at standard pressure and temperature. Water is also a necessity of all biotic forms in the earth. Water moves continually through the water cycle. Sewage Water Sewage water is carried waste in the form of solution or suspension. It is from manââ¬â¢s waste from his daily activities. Classes of sewage include sanitary, commercial, industrial, agricultural and surface runoff. The wastewater from residences and institutions, carrying body wastes (primarily feces, urine and semen), washing water, food preparation wastes, laundry wastes, and other waste products of normal living, are classed as domestic or sanitary sewage. Liquid-carried wastes from stores and service establishments serving the immediate community, termed commercial wastes, are included in the sanitary or domestic sewage category if their characteristics are similar to household flows. Wastes that result from an industrial process or the production or manufacture of goods are classed as industrial wastewater. Their flows and strengths are usually more varied, intense, and concentrated than those of sanitary sewage. Surface runoff, also known as storm flow or overland flow, is that portion of precipitation that runs rapidly over the ground surface to a defined channel. Precipitation absorbs gases and particulates from the atmosphere, dissolves and leaches materials from vegetation and soil, suspends matter from the land, washes spills and debris from urban streets and highways, and carries all these pollutants as wastes in its flow to a collection point. Bacteria Bacteria are from the Kingdom of Prokaryotes. They are very abundant in the earth and are one of the very first life forms to exist. Usually a few millimetres long and are spherical, rod or spiral in form. They may be found in almost every habitat. They play a big role in recycling nutrients like in the conversion of compounds and in the fixation of nitrogen. These bacteria can adapt to environmental conditions very well and survive wherever they are placed. CHAPTER III- MATERIALS AND METHODS In making this experiment, the researchers must prepare the following materials the sample bottle must be prepared for the collection of sewage water. It has to be properly labeled to avoid misuse/confusion. The researchers will get the plastic films from a plastic processor and distributor. The next steps would be with a help of a certified scientist. In the isolation of the bacteria, either way for a dilute sample such as water you would probably have to concentrate the sample. It is best to have a few liters of sample. First filter out the particulate matter with a 20 uM filter, then you can use water sampling nitrocellulose filter disc of 0.2 um. This probably needs a vacuum pump to draw the water through. You can then rinse this disc or swab it with a moist swab and use a series of dilutions to inoculate agar plates. Take a 10 ul drop and spread it out over the agar plate using a sterilized spreader. The agar i use for water samples is mostly very dilute in nutrients so that I do not have an overgrowth of one type of bacteria. I have used 1/5th strength nutrient agar, that is the nutrients do not dilute the agar strength. There are a whole variety of water based agars but the ISP2 media diluted to 1/4 strength was one of the best.. You can also take some of the waste water and filter it and use it for making wastewater agar to see if this will produce any colonies or try adding a very small amount of diluted nutrients. As above you can also use a host of diagnostic agars to see if there are any particular groups of organisms in the water. Another factor is the temperature of incubation. This is probably the best temperature to isolate the most organisms. Use room temperature incubati on or 10C incubation to isolate the widest variety of organisms. If you use 37C you will probably only select out a few organisms. The researchers may try some under anaerobic conditions also if they have anaerobic jars. Generally at low temperatures colonies might not develop for a few weeks, so after a day you might have to wrap your plates with parafilm or keep them in moist conditions to prevent them drying out.

The Future of Mankind Essay -- Philosophy God Philosophical Essays
The Future of Mankind If we compare the present with the past, if we trace events at all epochs to their causes, if we examine the elements of human growth, we find that Nature has raised us to what we are, not by fixed laws, but by provisional expedients, and that the principle which in one age effected the advancement of a nation, in the next age retarded the mental movement, or even destroyed it altogether. War, despotism, slavery, and superstition are now injurious to the progress of Europe, but they were once the agents by which progress was produced. By means of war the animated life was slowly raised upward in the scale, and quadrupeds passed into man. By means of war the human intelligence was brightened, and the affections were made intense; weapons and tools were invented; foreign wives were captured, and the marriages of blood relations were forbidden; prisoners were tamed, and the women set free; prisoners were exchanged, accompanied with presents; thus commerce was established, and thus, by means of war, men were first brought into amicable relations with one another. By war the tribes were dispersed all over the world, and adopted various pursuits according to the conditions by which they were surrounded. By war the tribes were compressed into the nation. It was war which founded the Chinese Empire. It was war which had locked Babylonia, and Egypt, and India. It was war which developed the genius of Greece. It was war which planted the Greek language in Asia, and so rendered possible the spread of Christianity. It was war which united the world in peace from the Cheviot Hills to the Danube and the Euphrates. It was war which saved Europe from the quietude of China. It was war which made Mecca the centre of the East. It was war which united the barons in the Crusades, and which destroyed the feudal system. Even in recent times the action of war has been useful in condensing scattered elements of nationality, and in liberating subject populations. United Italy was formed directly or indirectly by the war of 1859, 1866, and 187O. The last war realised the dreams of German poets, and united the Teutonic nations more closely than the shrewdest statesmen could have conceived to be possible a few years ago. That same war, so calamitous for France, will yet regenerate that great country, and make her more prosperous than she has ever been. Th... ...n will look upon this star as their fatherland; its progress will be their ambition; the gratitude of others their reward. These bodies which now we: wear belong to the lower animals; our minds have already outgrown them; already we look upon them with contempt. A time will come when Science will transform them by means which we cannot conjecture, and which, even if explained to us, we could not now under stand, just as the savage cannot understand electricity, magnetism, steam. Disease will be extirpated; the causes of decay will be removed; immortality will be invented. And then, the earth being small, mankind will migrate into space, and will cross the airless Saharas which separate planet from planet, and sun from sun. The earth will become a Holy Land which will be visited by pilgrims from all the quarters of the universe. Finally, men will master the forces of Nature; they will become themselves architects of systems, manufacturers of worlds. Man then will be perfect; he will then be a creator; he will therefore be what the vulgar worship as a god. But even then, he will in reality be no nearer than he is at present to the First Cause, the Inscrutable Mystery, the GOD.
