Coolidge, Calvin

Coolidge, Calvin Coolidge, Calvin, 1872â€"1933, 30th President of the United States (1923â€"29), b. Plymouth, Vt. John Calvin Coolidge was a graduate of Amherst College and was admitted to the bar in 1897. He practiced (1897â€"1919) law in Northampton, Mass., entered state politics as a Republican, and rose steadily in the party. He served (1910â€"11) as mayor of Northampton, was a member of the Massachusetts state senate from 1912 to 1915 (its president after 1914), and was (1916â€"19) lieutenant governor before serving (1919â€"21) as governor. Coolidge rose to national prominence when he used the militia to end the Boston police strike in 1919. In 1920 he was nominated as Republican candidate for the vice presidency and was elected with Warren G. Harding. After Harding died, Coolidge took (Aug. 3, 1923) the oath of office as President. Untouched by the scandals of the Harding administration, he was easily elected to a full term in 1924. His personal honesty and New England simplicity appealed to t he American people, and his unquestioning faith in the conservative business values of laissez faire reflected the national mood. Coolidge's policies were aggressively pro-business. Through his appointees he transformed the Federal Trade Commission from an agency intended to regulate corporations into one dominated by big business. He twice vetoed (1927, 1928) the McNary-Haugen bill to aid agriculture and pocket-vetoed (1928) a bill for government operation of the Muscle Shoals hydroelectric plant. The presence in his cabinet of Herbert C. Hoover and Andrew W. Mellon added to the business tone of his administration, and Coolidge supported Mellon's program of tax cuts and economy in government. Through his public statements he encouraged the reckless stock market speculation of the late 1920s and left the nation unprepared for the economic collapse that followed. Coolidge chose not to seek renomination in 1928. After leaving office he retired to Northampton to write newspaper and mag azine articles and his autobiography (1929, repr. 1989). As first lady, his wife, Grace A. Goodhue Coolidge, was much admired for her poise and charm. A selection of his press conferences was edited by H. H. Quint and R. H. Ferrell (1964). See biographies by C. M. Fuess (1940), D. R. McCoy (1967, repr. 1988), J. Abels (1969), W. A. White (1938, repr. 1973), R. Sobel (1998), and A. Shlaes (2013).

Kants Humanity Formula - 1647 Words

Kant: The Humanity Formula Few formulas in philosophy have been so widely accepted and variously interpreted as Kants injunction to treat humanity as an end in itself(Hill, 38). Immanuel Kants views, as elucidated in his book, Groundwork of the Metaphysics of Morals, are based on the belief that people count by prohibiting actions which exploit other individuals in order for self-prosperity or altruistic ends. Ethics then, are confirmed by the dignity and worth of the rational agency of each person. Since human beings are the only rational beings capable of decision making and reasonable judgement, humanity must be valued. Kant proposes a test that ensures that humanity is treated with respect, and not used merely as an†¦show more content†¦Treating people only in ways to which they could consent, in so far as they are rational, not merely as means but also as an end, is a moral requirement. Say a young child has fallen onto a subway track and does not see the subway coming. You have the opport unity to alert the child of the oncoming train by grabbing a briefcase out of the hands of a man standing next to you and throwing it towards the child as to grab his or her attention. Kants theory holds that this action is morally permissible, assuming the man could rationally consent. The only downside to this is that the man must accept the minor inconvenience of having to buy a new briefcase and replacing the papers that were inside of the damaged one. What does this lead us to? Well some might question whether the man was treated respectively. The answer Kant offers for this is that he indeed was, seeing as how he only forfeited something one can attach a monetary value to, and as a result, saved a childs life. This brings us to Kants dignity versus price argument. Rational agents have a certain dignity that is incomparable to something with a price value. Above all, we should respect the value of our rationale. That which has dignity cannot be traded off for that which has price, and invariably, that which has dignity cannot be exchanged for other dignity values. A prime example of the latter part of argument is suicide inShow MoreRelated Kants Humanity Formula Essay1646 Words   |  7 PagesKants Humanity Formula   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Few formulas in philosophy have been so widely accepted and variously interpreted as Kant’s injunction to treat humanity as an end in itself†(Hill, 38).

Equal Opportunity in United States Armed Forces...

The American Military is widely viewed as a pioneer in bestowing equal opportunity for all of its uniformed members. I am going to study the Equal Opportunity in United States Armed Forces with a particular emphasis on Minorities and Women in the Military. The United States Armed Forces has the most diverse labor force in the World. There are five branches of the United States Armed Forces: Army, Air Force, Navy, Marines, and Coast Guard.

The percentage of African Americans continues to exceed population representation of the civilian labor force although there are less African Americans enlisting than years before. Hispanics are underrepresented in the military, but their percentages have increased over the years as it has in society. Minorities comprise proportionally less of the officer corps. The minorities in the active and reserve Army Forces representation levels are in line with the statistics among the pool of college graduates from which the second lieutenants and ensigns are drawn.

Literary research Free Essays

Nathan Furr finds many reasons for doing literary research.   He summarizes these to be â€Å"Experiencing the Other, learning compassion and service, gaining insight into ourselves, finding new ways of thinking, understanding and writing more clearly, and uncovering the joy of discovery and creation† (Furr, 3).   To these he also adds essentially, the power of literary research to combat misinformation. We will write a custom essay sample on Literary research or any similar topic only for you Order Now    Generally, Furr’s reasons are similar to my own; however, I would make some changes to his conclusions. Two of Furr’s claims with which I unequivocally agree are that literary research allows one the ability of â€Å"understanding and writing more clearly† as well as a major reason for literary research being â€Å"uncovering the joy of discovery and creation.† These two reasons are of key importance because the detective aspect of literary research is a large part of what makes it so appealing to me.   By extension, a pile of research serves little value even if the research was conducted merely out of my own curiosity because the compiling, organizing, and writing are all essential components in answering the initial question.   Without the writing forcing me to synthesize the facts I have discovered and draw coherent conclusions, the research itself as well as whatever conclusions I drew are more easily forgotten. The first reason Furr lists is â€Å"experiencing the Other.†Ã‚   While this does seem like a valuable reason, I would more likely phrase it as â€Å"expanding one’s world view.†Ã‚   At least for me, this broader category makes more sense.   In the example he gives about the man from Poland, I think not only do we get to see the world from his perspective, but through oral histories like this we gain a valuable insight into the time and place described.   Thinking of it as experiencing the Other feels uncomfortable to me in that it seems to separate the researcher from the research subject, and as I think Furr would agree, that distance is exactly what literary research often seeks to minimize. While Furr’s claim that literary research can aid in â€Å"finding new ways of thinking,† I had difficulty with his example of research for buying a computer.   At the end of this paragraph, he summarizes the process of research saying, â€Å"We start with a problem or question, being researching, follow leads, assemble materials, and then create a product† (Furr, 2).   I agree that this is how research is conducted; however, is that really finding a new way of thinking?   It seems more like gathering information to form a conclusion and it should thus be labeled something more like â€Å"providing information.† I think this is especially true because, aside from his example, literary research does not necessarily facilitate the discovery of new ways of thinking.   I think it is possible that one could research a topic and emerge with a legitimate conclusion or â€Å"product† but without any new way of thinking about the problem beyond having found a satisfactory conclusion.   Ideally, this would not be the case.   Anyone conducting literary research would discover a new way of seeing a problem, but I think it is too broad a generalization to assume that this is always true.   At any rate, I think if this is truly what Mr. Furr is asserting, it would fit better, for me, into the â€Å"expanding one’s world view† category. Furr also sees â€Å"gaining insight into ourselves† as another reason for doing literary research.   In describing this reason, Furr states that through literary research many people seek to essentially â€Å"unlocking what we have always known and affirming it to ourselves. (Furr, 2). This seems to be Furr’s most direct reference to researcher bias.   I found his lack of a full discussion of this topic to be a major shortcoming of his article.   True, research in it most basic form involves uncovering information, but the world—in literary and historical senses as well as many others—is a very complex web of thoughts, experiences, and interpretations. I would argue that there is no one Truth, and the belief in such a thing is naà ¯ve.   The most obvious case would be the Bible.   Many different people seek to use the Bible to support very different claims.   Often passages sighted are contradictory and can easily support conflicting contentions.   The literary researcher does uncover information, but what is uncovered is only part of the story.   Which part is uncovered is largely reliant upon the sources one utilizes. The selection of source is also a product of bias.   For example, I would not use a Hindi newspaper, nor would I look to an un-translated Mayan text.   These two can be seen as extremes because of linguistic inaccessibility, but in doing research we generally gravitate toward sources with which we are comfortable whether books, popular media, scholarly articles, newspapers, oral histories, or any number of available source material. Beyond comfort with sources, I think Furr’s assertion falters in that it does not explicitly take into account that researchers find what they seek.   This affirming of one’s own beliefs is key to researcher bias because, for example, people who want to claim that the Holocaust never happened, will do so regardless of any information others try to point out to them.   Further, they will conduct their own research and doubtless find material that supports their conclusion, however false that conclusion may seem to be. Furr discusses the power of misinformation, but fails to consider the fact that many people do research and come up with unpopular conclusions that fly in the face of nearly all other findings.   Simply because we know it happened, when looking at the issue of the Holocaust we can claim that people denying it existence are spreading misinformation, but with more complex issues, and issues for which there are not survivors, it becomes clear that one person’s misinformation can be another’s highly researched cutting-edge discovery.   It all depends on where you look and what you are hoping to find. Another of Furr’s reasons for literary research—learning compassion and service—seems a bit optimistic to me.   Of course, we would like to believe that knowledge conquers darkness, but again compassion is a highly subjective issue.   Many people research literature, science, and history either explicitly in search of or resulting in reasons to assert their own superiority and use to oppress others.   One example would be people who researched, and still do research, on the biological inferiority of minorities to perpetuate and legitimize racist practices.   Finding compassion in such research is difficult if not impossible. In terms of service though, I enjoyed Furr’s claim that research is an ethical action.   While again this statement seems a bit simplistic, I think the argument he quotes from Altick and Fenstermaker that literary research can serve to extend â€Å"the traditional boundaries of scholarly and critical interest† is a valid one (Furr, 2).   While I do find Furr’s claims to be optimistic, I agree that in the best-case scenarios they are both true and of extreme value, but it is important to highlight some possibilities for which his arguments do not seem to account. I do agree that there are many important reasons both personal and social to undertake literary research.   Perhaps the strongest impetus for doing research is curiosity, â€Å"is that so?   I’ll look it up.†Ã‚   On an individual level when someone makes a seemingly unrealistic claim, literary research is an important tool in satisfying curiosity and quelling argument. Investigating misinformation is also very valuable on a larger social level.   This calls to mind the Program on International Policy Attitudes 2003 study that surveyed Americans to determine their rate of misperception about three issues surrounding the Gulf War and found that 80% Fox News viewers held at least one of the misperceptions (PIPA, 13).   To me, this illustrates the importance of literary research more than any other example. If one accepts information from one source uncritically, then they are completely at the mercy of that source’s biases.   While I believe it is true that a researcher is limited by their own biases, at least those biases are their own.   Exposure to sources with different biases is important in opening up new avenues of inquiry, but undertaking literary research is vital to locating other biases and interpreting information provided by those sources.   Literary research then is the key to knowing not only one’s own mind, but understanding the minds of others, and thus one of the most valuable tools anyone can employ in developing intellectually, personally, and socially.

The Papacy as represented in Peruginoapos;s The Gift of the Keys Essay Example

The Papacy as represented in Peruginos The Gift of the Keys Paper The Papacy as represented in Peruginos The Gift of the Keys Before I discuss the importance of various symbols in Peruginos The Gift of the Keys, it is important to note that the vast majority of my knowledge about the significance of the participants and architecture in the painting come from the writing of art historian Carol Lewine, whom in her recent book discusses the fifteenth century frescoes of the Sistine Chapel (65-74). I will be following her identifications, and adding to them my own interpretations of the contribution of artistic conception and composition to meaning and effect. What makes Peruginos painting significant are the strong political, religious, and social comments made through the powerful symbols in Peruginos work. One of thefirst, and most important, elements to notice in The Gift of The Keys is the way nearly every object in the painting manages to focus attention on the central figures of Christ and Peter. Even though the two are not physically separat ed from the rest of the figures in the scene, it becomes immediately obvious to the viewer that Christ and Peter are the principal subjects of this painting. To the left of Christ stand six apostles, the other six apostles (counting Peter) positioned immediately to his right. Also flanking Christ and Peter are the dual representations of the Arch of Constantine, and immediately in bac of Christ and Peter is the glorious Temple of Solomon. The important aspect of this centralization of Christ and Peter is that it shows that even with all of the other symbols in the painting, the most important one is the gift of the keys. When Christ hands the two keys to Peter, he symbolically hands him the power to distinguish between good and evil, and the power to bind and loose or to absolve sinners after appropriate penance, as Lewine puts it. (70 Lewine) Peter is often thought of roughly as thefirst pop

How to Demonstrate That Air Has Mass

How to Demonstrate That Air Has Mass Air is the sea of particles in which we live. Wrapped around us like a blanket, students sometimes mistake air as being without mass or weight. This easy weather demonstration proves to younger students that air does indeed have mass! In this experiment, two balloons, filled with air, will be used to create a balance. Difficulty: AverageTime Required: Under 15 minutes Materials Needed 2 balloons of equal size3 pieces of string at least 6 inches longA wooden rulerA small needle Getting Started Inflate the two balloons until they are equal in size and tie them off. Attach a piece of string to each balloon. Then, attach the other end of each of the strings to the opposite ends of the ruler. Keep the balloons the same distance from the end of the ruler. The balloons will now be able to dangle below the ruler.Tie the third string to the middle of the ruler and hang it from the edge of a table or support rod. Adjust the middle string until you find the balance point where the ruler is parallel to the floor. Once the apparatus is completed, the experiment can begin.Puncture one of the balloons with the needle (or other sharp object) and observe the results. Students can write their observations in a science notebook or simply discuss the results in a lab group.To make the experiment a true inquiry experiment, the objective of the demonstration should not be revealed until after students have had a chance to observe and comment on what they have seen. If the purpose of the experi ment is revealed too soon, students will not have the chance to figure out what happened and why. Why It Works The balloon that remains full of air will cause the ruler to tip showing that the air has weight. The empty balloon’s air escapes into the surrounding room and is no longer contained within the balloon. The compressed air in the balloon has a greater weight than the surrounding air. While the weight itself cannot be measured in this way, the experiment gives indirect evidence that air has mass. Tips In the inquiry process, its best to not reveal the objective of an experiment or demonstration. Many teachers will actually cut off the title, objective, and opening questions for lab activities so that students observe the experiments knowing the outcome will help them to write their own title and objectives. Instead of standard after-lab-questions, ask students to complete the missing title and objectives. It is a fun twist and makes the lab more creative. Teachers of very young students can even play this up creating a scenario in which the teacher accidentally lost the rest!Goggles are recommended for young students. When the balloons are blown up to a large size, small pieces of latex could injure the eye. Its also a good idea to use something other than needles to bust the balloon. Go around the classroom and check on the apparatus set-up. Then, once the apparatus meets the standards, the teacher can bust the balloon.
