The Second Treatise On Civil Government And State Of Nature

Throughout 17th century England, religion had a huge impact on the way the government was ruled. In turn, this has caused many problems amongst different sects, most notably in the lead up to the publication of John Locke’s The Second Treatise on Civil Government and A Letter Concerning Toleration. It would appear that the official religion of Britain would change with the hands of the monarch at the time, particularly during the period known as the ‘Wars of the Three Kingdoms’ and later the ‘Glorious Revolution.’ With this in mind, Locke identified the problem of allowing magistrates to enforce religious beliefs on the Commonwealth and so separated the Church and State. This separation is largely due to his ideas written out in Social Contract, which places a substantial limit on the government’s role in religion. In order to discuss the eventual separation of Church and State, one must first understand the importance of Locke’s Social Contract in relation to the magistrate’s power. Unlike Thomas Hobbes’ view on the State of Nature, Locke’s works make an attempt to eliminate absolute rule and consequently proposes that the State of Nature is positive. In Locke’s eyes, the State of Nature was not something human beings want to get out of, but rather are forced to with the introduction of private property and money. Nevertheless, this innate desire to want to improve common stock comes from God given rationality thus making human beings fundamentally rational.

What Causes A Crisis Free Essays

Such a question may at first seem unanswerable because there are so many different kinds of unpleasant situations into which we humans can get ourselves. In one word, however, the real culprit is probably ignorance. Ignorance, as used here, does not imply a lack of formal education, since one frequently sees highly educated persons getting into serious personal crises. We will write a custom essay sample on What Causes A Crisis or any similar topic only for you Order Now Real ignorance is a lack of understanding of the law of cause and effect in our own lives. Many of us seem to think that we can do whatever feels good–acquire wealth, achieve status, pursue romantic conquests, eat heartily, and so forth– ften at the expense of others, without ever having to concern ourselves with the consequences of such living. We foolishly ignore the karmic wisdom expressed in those popular phrases: â€Å"What goes around comes around. † and â€Å"Whatsoever a man sows, that shall he also reap. † Pain, unpleasant as it may be, is our stern benefactor. It teaches us vital lessons as to the conduct of our lives. Feeling pain means that something just isn’t working and that it’s time to change ourselves or get help through another’s experience. Getting help is a wise first step toward overcoming ignorance. When we hurt and really need the help, we listen attentively with mind and heart. We begin to learn those lessons which will prevent us from getting into similar predicaments later on. Some of us have to suffer consequential pain over and over before we are finally ready to seek out its causes. But eventually we say â€Å"Enough! and get to work. What if the crisis is not our fault, we might ask. Frequently a crisis victim who thinks himself to be blameless will lash out at society, chance, God, fate, the system, his family, or whatever other abstraction it is most convenient to blame. But the threads of cause and effect are many and multicolored. Our puny minds can hardly know for sure how or when an effect will blossom from a previous cause, nor what combinations of circumstances are being dealt to us by our own past choices. We are the masters of our future because we are free beings, but we are equally the slaves of our past and must pay folly’s price. Helpers in many different roles are available to give us the timely aid we need when in crisis. There are friends, psychiatrists, pastors, counselors, teachers, crisis line operators, doctors, nurses, social workers, nd numerous other sources of reeducation when we are up against a wall. If we will only ask them, they can help us overcome that ignorance which has, at least in part, caused us our present agony. Situations are many and varied, but it is safe to say that a situation never becomes a crisis until it involves pain. Pain spurs us on to ask, and exactly at that point is where solid and beneficial learning can begin. Whatever our diplomas and degrees, this is the only real learning. It is this learning that sets us free. Ignorance, mistakes, pain, learning, freedom–so goes the eternal cycle of human evolution. How to cite What Causes A Crisis, Essay examples

The Characteristics of Pictorialism Essay Example For Students

The Characteristics of Pictorialism Essay I the following essay I am going to be looking at what I believe to be the key characteristics of Pictorialism as well as this I will also be looking at the people I believe to of had the most impact on Pictorialism as a movement by analysing there works and ideology’s, by doing this I hope to answer the question ‘What are the characteristics of Pictorialism? ’ in a fulfilling and informative way whilst giving my biased and cynical British views on certain aspects, characters and events within the movement. The phrase Pictorialism was first coined within the context of photography in Henry Peach Robinson book entitled ‘Pictorial Effect in Photography: Being Hints On Composition And Chiaroscuro For Photographers. ’ Written in 1869 an age when ‘’9 out of ten photographers are ignorant to art’’ and the photographic proses was seen by most as something scientific opposed to something that can in the right hands be art. In many ways Pictorialism came about as a reaction to the small minded and bigoted nature of the art world of this time (its still pretty much the same today), it is because largely of Pictorialism that photography is accepted in the art world today. Naturalism and Peter Henry Emerson There are many characteristics in Pictorialism one of its most notably being it’s out of focus style. This is something that evolved as a characteristic of Pictorialism when it was still only a baby and was developing from its distant cousin naturalism, this now famous characteristic was originally pushed by someone who would have, in the early 1880’s made only stunning sharp pictures of nature, this was Peter Henry Emerson, a photographers whose roots lye within Naturalism and bird watching. Emerson later became one of the key figures in having photography accepted as an art form writing 8 books on photography and a manuscript entitled a history of artistic photography (1936), He originally pushed the idea of out of focus images to his students instructing them to make photographs ‘’just as sharp as the eye sees it and no sharper’’ . Believing much like many do now with digital photography that the images presented by the camera were not in fact a true representation of what the human eye could actually see. The Development of Pictorial Effect Where as Emerson strived often for the truth within the image, Pictorialism started to move away from this in 1890 where much like in art the substance within the image starting to become more important ‘stressing beauty over fact’ this became apparent within the development of the ‘pictorial effect’ inspired by the atmospherically soft brush strokes of painter from the Barbizon school. Photographers believed that by coating their own paper, before or during the development process with obvious brush strokes and marks, made their photographs works of art opposed to works of science replicating effects that were created when making a painting almost as if they were trying to re-create the authenticity of classic works of art that people at that time didnt feel photographs possessed. I feel these brush strokes also made the work feel as though it was not just an image trapped in a piece of paper but a work that now stood out and belonged in a three dimensional world opposed to a flat one. The brush strokes much like choosing to use a softer focus also aloud the photographer to portray his or her own objective view of the scene it was this that manly the photographer Robert Demachy felt separated the art of photography from the straight science of photography that you see in Eadweard Muybridge’s work ‘’A straight print may be beautiful, and it may prove upper abundantly that its author is an artist: but it cannot be a work of art.. work of art must be transcription, not a copy of nature it must be subjective not objective’’ I feel as though this quote from Demachy sums up quite nicely the points put across in the previous paragraph and sums up many of the thought and practical methods behind the movement of Pictorialism. Animal Locomotion, Plate 695, Eadweard Muybridge, 1880s Robert Demachy Most well known for this painterly effect is the photographer Robert Demachy. In his work he uses the brush strokes in such a way that the effect loses the somewhat gimmicky look that I feel it can sometimes be associated with. These brushstrokes on Demachis work do not look as though he is trying to copy a painting neither do they look like random marks with an image printed over the top, these marks become part of the image creating new tones, light and dark depending on where they have been placed on the paper. In his work ‘study of a head’ the marks blend into the clothing creating long flowing lines blurring what we preserve as a true image. Turkey Religion EssayIn the 20th century Pictorialism was described as becoming ‘’darker, more symbolic and personal, reflecting the rise of modernist art and the experience of displaced peoples across Europe and the united states’’ Were as the more complex and extravagant printing techniques previously used were replaced by cheaper and easier techniques such as gelatin silver printing and photogravure. This aloud for more prints to be made at a cheaper cost, ironically I feel this completely goes against earlier standard and ways of thinking in the Pictorialist movement, de-valuing the work and the artist credibility they believed came from something rare and authentic. Leaving its roots in Naturalism behind Pictorialism moved away from the more romanticised countryside shots common in Europe to a harder grittier urban settings, often trying to find beauty in unlikely location, Stieglitz who continued to work mostly on the streets of New York started to move further away from the more traditional Pictorialist styles taking inspiration from Japanese artist such as Katsushika Hokusai and Utagawa Hiroshige. Where as some photographers of the time such as Pierre Dubreuil (1872-1944) starting making more progressive pieces combining futurist and cubist ideas into the mix and unlike most other Pictorialist emphasizing designee over contented the old boys, Stieglitz, Steichen ext. ecame more self obsessed moving away from landscapes and portraits of young children to continuously photographing themselves and each other for example in the peace Frank Eugene, Alfred Stieglitz, Heinrich Kuhn and Edward Steichen Admiring the Work of Eugene (1907), I think certain thing like this are with other factors important to the downfall of Pictorialism as a major player in the art/ photography world, I dont think I would be alone in thinking towards the end of Camera Work’s influence Stieglitz hindered the movement more than he helped it continually turning friends into enemy for what he saw as ‘challenging his authority’ or disagreeing with his ideas, in many ways he was as much of a dictator of Pictorialism as he was a creator, like the moustached love child of a Kim Jon-Un and a more socially acceptable visionary. With this ‘obsessive’ self portrait talking came certain comments in the book .. o and so said, ‘’There was renewed interest in the inner depths that could be revealed in a portrait, seen most tellingly in the works of Steichen, Coburn and Frank Eugene. ’ As photography was slowly accepted into the ignorant and snobby art world Pictorialism and it’s influence and relevance started to fade and along with it was some of it’s key practitioners, Alfred Stezaker started to make more traditional images stating ‘’My photographs look like photographs- and (in the eyes of the ‘pictorial photographers’) they therefore can’t be art’’ 21 (1923) And the camera club he was part of was torn apart by his own ever enlarging ego, although Pictorialism was still practiced after WW1 it no longer had as much relevance in a more accepting art world. Conclusion The characteristics of Pictorialism can not just be defined by the work made and the techniques used by the artist, it is true that certain effects on images are in the brackets of Pictorialism, the painterly effects that showed human elements to the work which contradicted the ideas that photographs were machine made and there was no artist human element and therefor photography could not be an art. The soft focus which initially moved photography away from just recording events as they were seen even if that was not the original intention of Peter Henry Emerson but I feel the most important characteristic of Pictorialism was the relentless ways in which the artist pushed the movement, creating communities in the form of camera clubs, publishing journals and essays and touring exhibitions around the world as well as creating whole new spaces for Pictorialist work to be displayed, in doing this they not only got photography accepted into the art world but redefined modern art forever changing the ignorant face of the art world.

Tips for Urban Stargazers

Tips for Urban Stargazers Stargazing in the city? Why not?  Just because someone lives in an urban environment doesnt mean they cant do a little sky observing. Sure, its a bit tougher because of bright lights and overall light pollution, but it can be done.   Most articles  about stargazing  recommend finding a good, dark-sky observing site. But for someone living in the city, who cant get to a dark-sky reservations, its tempting to just stay inside and look at the stars on a computer screen. However, it turns out, there are ways to do some city observing, despite the problems posed by light pollution. Much of the worlds population lives in or near cities, so enthusiastic city stargazers can and do find ways to do back-yard or rooftop observing.   Explore the Solar System The Sun, Moon, and planets are readily accessible because theyre bright. The Sun is an obvious choice, but observers do need to take some strict precautions. NEVER look directly at the Sun with the naked eye and especially NOT through binoculars or a scope that dont have solar filters. If an observer has a  telescope  equipped with a solar filter, then they can look at it through the eyepiece, to see the sunspots and any prominences that might be moving up from the Suns surface.  As it turns out, however, theres a very low-tech way to see sunspots without filters. Heres how it works: let the Sun shine through the telescope, and direct the bright light onto a white wall or a piece of paper. The observer gets to see sunspots without burning their eyes out. In fact,  a number of successful sunspot observers use this method all the time. That method also makes it very easy to sketch sunspots since all the observer has to do is direct the view onto paper and then trace what is projected. Checking out the Moon The Moon is also a great target for city viewing. Watch it night after night (and in the daytime during part of the month), and chart how its appearance changes. Its possible to explore its surface with binoculars, and get really finely-detailed views with a good telescope. One popular pastime is to explore all the large basins and craters on the surface.  Another one is to look for mountains and cracks on the surface.   One thing to look for during an observing session is an iridium flare. Thats a glint of light from the surface of an Iridium satellite. These usually happen not long after sunset and are very bright, so bright then can be seen from cities. However, as Iridium satellitesd are gradually phased out, such flares will happen less and less frequently. Seeing Planets from the City The planets are also good targets for city skygazers. The rings of Saturn and the moons of Jupiter  are popular targets. Plus, they show up well in binoculars or a telescope. There are good observing guides to the planets in the pages of Astronomy, Sky Telescope, SkyNews  magazines, as well as many sources online in other languages. A  digital astronomy program or app, such as StarMap 2 or Stellarium also provide precise positions of the Moon and planets in the sky.   The Deep Sky From the Big City Unfortunately, many people who live in light-polluted areas have never (or rarely) seen the Milky Way. During a power outage, theres a chance of seeing it from the city, but otherwise, it can be very difficult to spot unless they can get a few miles outside of town.   But, all is not lost. There are  some deep-sky objects that city dwellers can try to find. They just need to get out of the way of lights. One trick that many urban observers use is to stay up after midnight when some building owners turn off their outside lights. That might allow a view of such things as the Orion Nebula, the Pleiades star cluster, and some of the brighter star clusters. Other tricks for city observers: Find places to observe from that are shielded from bright nearby lights, such as a corner of a porch, the top of a roof and next to a wall, or from a balcony;Some put a blanket over their heads and their telescopes to block out the direct light;City astrophotographers take long-exposure images of deep sky objects;Use  good star chats  that help a skygazer hop from star to star as you search out a cluster or a nebula.   Ask the Locals Local planetarium theaters often offer stargazing shows, where people can learn the night sky.  They might also have classes for stargazers, so check out the nearby facilities to see what they offer. They are often found in science centers, but also at universities and some school districts offer public access from time to time. Amateur astronomer groups in and near big cities often have observing nights where people can gather with others to do some sky exploration. For example, in New York City, the Friends of the High Line organization have weekly observing sessions from April through October. Griffith Observatory in Los Angeles holds star parties each month, and its telescope is available each week for a peek at the heavens. These are just two of many, many stargazing activities in towns and cities. Also, dont forget the local college and university observatories- they often have observing nights, too. The city might seem like the least likely place to catch a glimpse of the stars, but in cities from downtown New York to Shanghai to Bombay and beyond, people can still often see the brightest stars and planets. It may be a challenge, but the rewards are worth it.

How to Promote Student Growth

How to Promote Student Growth There is a growing need to measure students growth and success in the classroom, especially with all the talk in the media about teacher evaluations. Its standard to measure student growth at the beginning and the end of the school year with standardized testing. But, can these test scores give teachers and parents a good understanding of the students growth? What are some other ways educators can measure students learning throughout the year? Here we will examine a few ways that teachers can promote student understanding and performance. Ways to Promote Student Development According to Wong and Wong, there are some ways professional educators can promote student growth in their classroom: Set high expectations for student achievementMake sure that students perform at or above expectationsSolve problems so students will receive servicesUse up to date research and technologyPlan instructional strategiesApply higher-order learning skillsApply information-processing strategiesApply complex learning tasksUse cooperative learning in the classroomUse invitational learning in the classroomArticulate information clearlyApply classroom management These suggestions that the Wongs gave will indeed help students to achieve and demonstrate their abilities. Promoting this kind of learning can help students prepare for the standardized testing that measures their growth throughout the year. By using the suggestions from the Wongs, teachers will be preparing their students to be successful on these tests while promoting and developing important skills. A Variety of Ways to Measure Student Performance Measuring student growth solely on standardized tests have always been the easiest way for teachers to determine that the students are grasping the information taught. According to an article in the Washington Post, the problem with standardized tests is that they mainly focus on math and reading and do not take into account other subjects and skills students should be developing. These tests can be one part of measuring academic achievement, not the whole part. Students can be evaluated on multiple measures such as: Growth throughout several yearsPortfolio of students work in all subjectsExamsCritical thinking skillsProblem-solving skillsGroup ProjectsWritten and oral presentationsClass projects and experiments Including these measures along with standardized testing would not only encourage teachers to teach a wide range of subjects well but would also accomplish Presidents Obamas goal to make all children college ready. Even the poorest of students would have the opportunity to demonstrate these critical skills. Achieving Student Success To achieve students academic success, it is paramount that teachers and parents work together to help develop and build skills throughout the school year. A combination of motivation, organization, time management, and concentration will help students stay on track and be able to achieve successful test scores. Use the following tips to help students achieve success: Motivation To help motivate students to find out what they are passionate about and use their interests to connect with their school work. Organization For many students, something as simple as staying organized is the key to academic success. To help students stay organized, organize and label all materials and notebooks and keep a checklist of essential tasks. Time Management Learning to prioritize and manage time can be difficult for students. To help them manage their time keep track of assignments and tasks by creating a school calendar. Concentration Students get distracted very easily, to keep their minds on the task at hand enlist parents to designate a quiet zone for homework where there are NO interruptions. Sources: Wong K.H.

Emerging Technologies that address interoperability issues in an Essay

Emerging Technologies that address interoperability issues in an e-business environment - Essay Example New technologies have been introduced through e-commerce to give a wider exposure and innovate new ways of conducting businesses, which has introduced a new dimension in technology known as E-business. E-business’s presence is important for expansion in business, dissemination of information and access to physically inaccessible markets. In today’s dynamic world, companies spent heavily on their IT departments for the technical support to smoothly run their e-commerce activities. Companies even develop strategies through e-business to reduce cost of the business, expand sales and increase customer services and satisfaction in the long run. E-business is widely used for many business purposes like product research, order entry; customer’s related matters like support, services, communication, inquiry, invoicing etc., outbound and inbound logistics. E-commerce has revolutionized not only businesses but every aspect of life; the world is now a click away. (Ray, 3) C hallenge from the Competitor in E-Business Environment including Supply Chain Due to increased e-business services and advancement in IT related matters, competition has geared up in every sector tremendously. Nowadays, competition has intensified due to e-business activity like business to business (B2B) or business to consumer (B2C) transactions or transactions that incur after sale. These facilities and easiness to conduct business has caused cost efficiency which has attracted more competition in every sector. Increased Competition Due to Low Entry Barriers Due to tremendous benefits offered by the e-business, the competition has increased, which has affected business in many ways. The e-business has lowered market entry barriers and it is now comparatively very easy to enter business than it was previously. Initially, large investments and established contacts were needed to start up a business which is now replaced by easy entry in to the markets which is now a click away. Thi s has made competition severe and is a threat to many established business. The internet as a medium to exchange information has made customers close to the businesses which has brought great challenges to the existing businesses. Now there is a continuous threat to every business that another business established in no time can take away its customers. Thirdly, globalization has added to the increasing competition. Internet allows the customers to exchange information anywhere in the world, which has made the businesses of the world compete with each other. (United Nations, 142) Continuous Cost Reduction Due to e-business, the markets now seem to be more of a perfect market where there are many competitors striving to gain their positions. In such a market, cost leaders prevail. Due to closed links of customers and suppliers in the supply chain, cost reduction is an achievable task in today’s business and many business strategies are based on this. In this cost reduction rac e, every business has to continuously work on its cost reduction strategies in order to compete effectively. Secondly, the transaction costs are reduced for the customers due to extensive information available over the internet. This also puts up a pressure on the businesses to increase their presence over the internet. (United Nations,
