Criticaly evaluate the claim that conscience is dictated Essays

Criticaly evaluate the claim that conscience is dictated Essays Criticaly evaluate the claim that conscience is dictated Essay Criticaly evaluate the claim that conscience is dictated Essay Essay Topic: Claim Of Value For example, you can describe two different situations to a six year old, one of which is someone lying and a minor bad consequence arising, the other is someone accidentally causing a very negative consequence. For a six year old, the latter case would make mummy more cross because their understanding is that something is bad because it hurts or upsets people. Ask an older child, and they will accurately say that a parent would be more cross with the child who told a lie. Pigged is showing that conscience is something we learn as we grow and develop. This theory seems to contradict Newsmans ideas. Newman was an intuitionist, believing that conscience is the voice of God. He believed that when faced with a moral decision, we get a sense of moral direction from God, which we can either listen to or ignore. Conscience is an ability to detect the right course of action. For Newman, following the conscience was more important than listening to the teachings of the Pope. In this way, we do not learn what is right or wrong from our parents or from religious leaders or scriptures. Conscience is a law that speaks to the unman heart, a law written by God. Piglets view may seem more accurate, as it is possible to observe and validate it. However, many people do not like the implications of accepting this view. Pigged is not claiming that there is any moral truth, he does not believe in objective morality or absolute rules. Whilst a person might develop respect for others whichever society they are brought up in, other aspects of morality will vary according to your upbringing. The percentage of people who feel guilty is higher in Christian households. For many Christians, there are absolute moral rules. Catholics would argue that feeling guilt is a sign from God that you have done something wrong. When challenged to explain how children develop, a follower of Newman might claim that a younger child cannot sense Gods direction clearly, and it is our ability to hear Gods voice that develops as we grow. Freud was a strong critic of religion. The guilt which people feel is merely a result of events in our childhood and the disapproval of society. This explains why different societies have different values. In Islam, a man may marry four wives this idea would be repugnant to many Christians. For Freud, the superego exists in our subconscious and reflects negative experiences, and in a healthy person the ego, our conscious personality, is in control and overrides the guilty conscience. For Freud, conscience is not taught as such, it develops subconsciously. Many people criticism this view of the conscience. It is very negative, yet our conscience can be useful in preventing us from doing things that harm ourselves or others. Many psychologists agree with Freud that conscience develops subconsciously, but reject the idea of the conscience as an entirely negative hinge. Aquinas had a very different view of the conscience, and would have totally rejected Frauds notion of a negative subconscious superego. He was not an intuitionist, and would not have agreed with the idea of conscience as the Voice of God. Instead, he believed we have a God-given faculty of reason. Humans are inclined to do good and avoid evil. He called this Synthesis. In a way, then, this is the antithesis of Freud, a positive, subconscious will to do what is right. With this subconscious ability, we can grasp the basic purposes of human life to survive, evolve, reproduce, learn, worship God, live in a civilized society. For Aquinas, the first part of the conscience was this subconscious grasp of the Primary Precepts. The next part of the conscience was what he called conscientious, which is the rational ability to distinguish between different courses of action,conscience is far from being the voice of God, but neither is it learnt. We may learn to use our moral Judgment more effectively, but conscience is the dictate of reason. Conscience is a God given ability, not something learnt and not the Voice of God. Critics of Aquinas say that if e was right, we would all reach the same conclusions about what is right or wrong. For example, we would all agree about whether it is right for two men to get married. However, people disagree strongly about this question. For many Christians, they believe that our ideas of right and wrong should come from the Bible, which they may believe is the word of God. Conscience for them is something learnt. Others believe that being Christian means having an indwelling of the Holy Spirit. They may believe that Gods Spirit living inside us is the voice of God. Butler believed that Aquinas was right to see reason as supreme. He agreed that our conscience should have ultimate authority over our actions. If conscience were something learnt, if it was taught to us, then where would its authority come from? Peoples consciences would develop differently according to where they live and how they were brought up. Butler would have been much happier thinking of conscience as the voice of God. His position was much closer to Aquinas. He saw conscience as our natural guide, the guide assigned to us by the Author of our nature. For Butler, our natural instincts re to look after ourselves. We also have a desire to help others, and it is the consciences Job to weigh up these two opposing interests of self-love and benevolence. For Butler we have a God-given ability to Judge what is right or wrong, similar to Newsmans voice of God, but rather than being a voice it is a faculty to reason, a lot like Aquinas. For all three, seeing conscience as coming from God gives conscience a supreme authority over our actions. This allows for objective morality, for universal principles that all people should follow. This could lead to belief in universal human rights, a rejection of torture and arbitrary arrest, important ideas in the current discussions around the ethics of war. If the conscience were merely taught, there would be no source of moral authority, no objective standard by which to make declarations about inalienable rights. From had a theory of the conscience that was similar to Frauds, an authoritarian conscience that made us do things as a result of guilt or the fear of displeasing others.

How to Find Degrees of Freedom in Statistics

How to Find Degrees of Freedom in Statistics Many statistical inference problems require us to find the number of degrees of freedom. The number of degrees of freedom selects a single probability distribution from among infinitely many. This step is an often overlooked but crucial detail in both the calculation of ​confidence intervals and the workings of hypothesis tests. There is not a single general formula for the number of degrees of freedom. However, there are specific formulas used for each type of procedure in inferential statistics. In other words, the setting that we are working in will determine the number of degrees of freedom. What follows is a partial list of some of the most common inference procedures, along with the number of degrees of freedom that are used in each situation. Standard Normal Distribution Procedures involving standard normal distribution  are listed for completeness and to clear up some misconceptions. These procedures do not require us to find the number of degrees of freedom. The reason for this is that there is a single standard normal distribution. These types of procedures encompass those involving a population mean when the population standard deviation is already known, and also procedures concerning population proportions. One Sample T Procedures Sometimes statistical practice requires us to use Student’s t-distribution. For these procedures, such as those dealing with a population mean with unknown population standard deviation, the number of degrees of freedom is one less than the sample size. Thus if the sample size is n, then there are n - 1 degrees of freedom. T Procedures With Paired Data Many times it makes sense to treat data as paired. The pairing is carried out typically due to a connection between the first and second value in our pair. Many times we would pair before and after measurements. Our sample of paired data is not independent; however, the difference between each pair is independent. Thus if the sample has a total of n pairs of data points, (for a total of 2n values) then there are n - 1 degrees of freedom. T Procedures for Two Independent Populations For these types of problems, we are still using a t-distribution. This time there is a sample from each of our populations. Although it is preferable to have these two samples be of the same size, this is not necessary for our statistical procedures. Thus we can have two samples of size n1 and n2. There are two ways to determine the number of degrees of freedom. The more accurate method is to use Welch’s formula, a computationally cumbersome formula involving the sample sizes and sample standard deviations. Another approach, referred to as the conservative approximation, can be used to quickly estimate the degrees of freedom. This is simply the smaller of the two numbers n1 - 1 and n2 - 1. Chi-Squarefor Independence One use of the chi-square test is to see if two categorical variables, each with several levels, exhibit independence. The information about these variables is logged in a two-way table with r rows and c columns. The number of degrees of freedom is the product (r - 1)(c - 1). Chi-Square Goodness of Fit Chi-square goodness of fit  starts with a single categorical variable with a total of n levels. We test the hypothesis that this variable matches a predetermined model. The number of degrees of freedom is one less than the number of levels. In other words, there are n - 1 degrees of freedom. One FactorANOVA One factor analysis of variance (ANOVA) allows us to make comparisons between several groups, eliminating the need for multiple pairwise hypothesis tests. Since the test requires us to measure both the variation between several groups as well as the variation within each group, we end up with two degrees of freedom. The F-statistic, which is used for one factor ANOVA, is a fraction. The numerator and denominator each have degrees of freedom. Let c be the number of groups and n is the total number of data values. The number of degrees of freedom for the numerator is one less than the number of groups, or c - 1. The number of degrees of freedom for the denominator is the total number of data values, minus the number of groups, or n - c. It is clear to see that we must be very careful to know which inference procedure we are working with. This knowledge will inform us of the correct number of degrees of freedom to use.
