Mackies Argument Evil And Omnipotence - 1264 Words

Priya Patel Phil 104 Fall 2017 October 2, 2017 Paper 1: On Mackie’s Argument In J. L. Mackie’s â€Å"Evil and Omnipotence,† the author presents an argument detailing why belief in a both omnipotent and wholly good God is contradictory to a God who allows evil to exist. He utilizes this philosophy to show that God doesn’t exist due to the problem of evil. As Mackie’s delineates in his first paragraph, â€Å"I think, however, that a more telling criticism can be made by way of the traditional problem of evil. Here it can be shown, not only that religious beliefs lack rational support, but that they are positively irrational, that the several parts of the essential theological doctrine are inconsistent with one another.† (p. 100) Mackie discusses†¦show more content†¦2. If God is both omnipotent and wholly good, then He would make men freely choose good on every occasion. 3. It is not true that God makes men freely choose good on every occasion. 4. Therefore, it is not the case that God is an omnipotent and wholly good being. In the following paragraphs, I will elucidate Mackie’s belief in this argument and offer a critical evaluation of the former. To begin with, take a justification of the first premise. This says that God has a choice available to him that contains two things. One would be to make humans, in their free will, choose good occasionally over evil. The other would be to make humans, in their free will, choose good on every occasion over evil. Mackie states â€Å"If there is no logical impossibility in a man s freely choosing the good on one, or on several, occasions, there cannot be a logical impossibility in his freely choosing the good on every occasion.† (p. 105) Mackie believes that God is presented with this choice. Moving on to the second premise: in order for God to be classified as both omnipotent and wholly good, He would take the option to always make men choose good in their free will. Mackie’s thought process in believing this is linked with the definitions of omnipotent and wholly good in theism itself. These indicate that in order to be omnipotent, one must have no limit to what one can do, and in order to be wholly good, one would eliminate evil.

Mackie’s stern defense of the logical problem of evil, which he uses to suggest the God does not exist. I will attempt to defend the notion that both God and evil, in the form of human creation, can exist in the world by way of suggesting that freewill is the answer. Furthermore, I will strengthen the argument for freewill against Mackie’s defense, which suggests that the argument of freewill also compromises the Omni -three nature of God.

Rational Systemically, the patient,CJ is stable, his arm is very painful, to the crew, CJ’s injury is not life threatening however the pain is real and precautions need to be taken to stabilise the limb and to minimise nerve or soft tissue damage. Adequate pain relief is required. Nitrous Oxide,( commonly referred to as Entanox) provides analgesic properties suitable for fast and effective pain relief . Pharmacodynamics Administration of N2O is painless, with a rapid onset and a short duration of action. The onset is approximately 1 to 5 minutes and the recovery time is 3 to 5minutes once the gas has been with-drawn.( Pasaron R., Burnweit C. ,Zerpa J., Malvezzi L.,Knight C., Shapiro T., Ramos-Irizarry C., Velis E.) Inhaled N2O gas molecules are absorbed into the blood stream from the lungs. As noted by Oglesbee, it provides sedation stabilizing the neurons in the brain to prevent action potentials. N2O has low solubility in blood and is transported in solution without binding to proteins. It diffuses rapidly across the alveolar– arterial membrane and is excreted unchanged, mainly through the lungs.

Battering is a Momentary Loss of Temper Free Essays

Battering is a form of domestic violence, which involves physical actions aimed at instilling pain, harm the body or to propagate a feeling of intimidation to a partner so that one can get and maintain full control over the victim (Prakashan, 2001). Battering as an abusive behavior has a long trailing history in the global society and its awareness, legislation and perception varies from one country to the other. Several myths have been conceived with a purpose of explaining the main causes of battering. We will write a custom essay sample on Battering is a Momentary Loss of Temper or any similar topic only for you Order Now It is in this interest therefore that this paper is written. It seeks to refute the proposed myth that battering is a momentarily loss of temper. Reliable information from the American Medical Association has shown that domestic violence is not an instantaneous thing but a process, which is cultivated by various factors and in most cases over a certain period of time (National Coalition Against Domestic Violence, 2009). The same point is underscored by the Surgeon General of the United States report. True to the word, victims of battering have been subjected to this traumatizing experience over time. Momentarily loss of temper is, in my opinion dictates for occasional incidences of this abusive behavior, which is undoubtedly inhumane. The fact that battering is aimed at gaining and maintaining control over their partners as well as revenging or punishment for betrayals or mistakes done by the victim need to be appreciated right at the beginning of this discussion otherwise the rest of its content might not make the intended impact to the reader (Baskerville, 2006). Based on this fact and judging by the principles of reason one can see the possibility of a long and well planed battering incidence. For instance, unfaithfulness is a major drawback to the family but many a times, one of the partners may fail to have enough evidence on the same and therefore he or she has no ground for divorce (Prakashan, 2001). The problem becomes worse if their intimacy overcomes their desire to separate. This can amount to a feeling of betrayal, unhappiness and aggressiveness which as human beings, can accumulate to uncontrollable levels resulting to battering. Various studies have it that most women are more venerable to battering than men. This is evident in the physical strength of men as compared to women (National Coalition Against Domestic Violence, 2009). To avoid being branded a feminist, the author of this paper finds it necessary to mention that men are also victims of domestic violence mostly in forms of verbal and emotional abuse. As a matter of fact, physical abuse like battering is the highest order of family violence beyond which severe injuries or even death can occur (Buzawa, Buzawa, 2003). Domestic violence starts in the least form like altering abusive words. If the problem is left unsolved, it propagates and instills emotional instabilities like depression, keeping victims isolated from friends and family members. Still if this is left unattended, it will accumulate to levels which can amount to physical violence which is battering for this matter. In conclusion therefore, the above discussion dismisses the proposed myth that Battering is a momentary loss of temper. It underscores the fact that battering is a form of domestic violence which results from unattended simple forms of domestic violence like verbal and emotional abuse. It is indeed an inhuman act, but it is very common and hence it is the responsibility of any couples to address their differences in a more human manner. Simple forms of domestic violence should not be left unresolved otherwise they can amount to battering. References Baskerville, S. (2006).

National Health Service Analysis of Variance

Question: Discuss about the National Health Service for Analysis of Variance. Answer: Introduction There is a concern expressed that the general dental practitioners are more willing to work for NHS (National Health Service) after qualification however, later they choose private practice after gaining professional experience. To verify this concern, data regarding how many years the dentists have been practicing since qualification was collected for three sample groups of dentists: 1st: The Dentists working in National Health Service only, 2nd: The Dentists working in private practice only and 3rd: the Dentists working in National Health Service and Private practice. Thus Null hypothesis H0: The mean of the different groups will be equal Alternative Hypothesis H1: The mean of the different groups will not be equal The data collected is given below NHS only Private only NHS and Private 12 15 5 27 26 16 1 38 38 26 7 24 4 33 4 6 25 42 18 12 13 23 42 22 3 31 2 10 22 28 2 16 32 3 37 37 1 The scatter plot diagram of the above data is given below where 1 is the sample of dentists working in NHS only, 2 is the sample of dentists working in private practice only and 3 is the sample of dentists working in NHS and private practice. Each group has a sample of 12 dentists and the number of years they have practiced since qualification is noted. The each sample group is plotted on the x axis while the number of years they have practiced since qualification is on the y axis. 2 To find the one way analysis of variance We know for the calculation of one way ANOVA, we need to calculate for each group mean and (X - X0)^2, where X is the sample data and X0 is the mean of the sample. Thus, calculating the values for each group we have, NHS only Private only NHS and Private Data (X - X0)^2 Data (X - X0)^2 Data (X - X0)^2 12 0.56 15 106.78 5 286.17 27 248.06 26 0.44 16 35.01 1 105.06 38 160.44 38 258.67 26 217.56 7 336.11 24 4.34 4 52.56 33 58.78 4 321.01 6 27.56 25 0.11 42 403.34 18 45.56 12 177.78 13 79.51 23 138.06 42 277.78 22 0.01 3 68.06 31 32.11 2 396.67 10 1.56 22 11.11 28 37.01 2 85.56 16 87.11 32 101.67 3 68.06 37 136.11 37 227.51 Mean 11.25 25.33333 21.91667 (X - X0)^2 1058.25 1384.667 2150.917 We need to calculate mean and (X - X0) ^2 for overall data as well. Overall data (X - X0)^2 12 56.25 27 56.25 1 342.25 26 42.25 4 240.25 6 182.25 18 2.25 23 12.25 3 272.25 10 90.25 2 306.25 3 272.25 15 20.25 26 42.25 38 342.25 7 156.25 33 182.25 25 30.25 12 56.25 42 506.25 31 132.25 22 6.25 16 12.25 37 306.25 5 210.25 16 12.25 38 342.25 24 20.25 4 240.25 42 506.25 13 42.25 22 6.25 2 306.25 28 72.25 32 156.25 37 306.25 Mean = 19.5 (X - X0)^2 = 5889 Thus summarizing the overall data we have NHS only Private only NHS and Private Overall Mean 11.25 25.33333 21.91667 19.5 n 12 12 12 36 Sum X 135 304 263 702 (X-X0)^2 1058.25 1384.667 2150.917 5889 Thus difference within the group = 1058.25 + 1384.67 + 2150.91 = 4593.83 And the difference between the groups = 5889 4593.83 = 1295.17 The degree of freedom df for between group = 3 -1 = 2, the degree of freedom df for within groups = (12 -1) + (12 -1) + (12 -1) = 33. Thus, total degree of freedom = 33 + 2 =35 Mean is calculated by dividing sum of squares by df.

Thus we reject the null hypothesis. Thus we can say that there exist significant differences in the mean of the three groups. (Roberts, 2008) c) From the analysis done above we can conclude that the mean of the three samples which are 1st: The Dentists working in National Health Service only, 2nd: The Dentists working in private practice only and 3rd: the Dentists working in National Health Service and Private practice are significantly different i.e. the number of years practiced by the dentist in the three samples is different and we can say that number of years of practice by dentists in National Health Service and private are different. (Laerd Statistics , 2013) d) There is a significant difference among the mean of the number of years of practice by dentists in National Health Service and private. By looking at the mean values of the number of years of practice by dentists, it can be said that the number of years of practice by dentists in private is more than the number of years of practice by dentists in NHS as the mean value of the sample for private only is more than two times the mean vale for NHS only. Thus we can conclude that the dentist choose private practice after gaining professional experience.

In these interchapters, Steinbeck seems to step back from the story to examine the larger picture, but in truth, the author never forgets the reality faced by his characters. For instance, the different members of the family have characteristics which add to their problems and which also reflect larger forces at the same time. Grandpa Joad, for instance, is senile, and this symbolizes the vulnerability of the entire family.

Endothermic Reactions Demonstration

Endothermic Reactions Demonstration An endothermic process or reaction absorbs energy in the form of heat (endergonic processes or reactions absorb energy, not necessarily as heat). Examples of endothermic processes include the melting of ice and the depressurization of a pressurized can. In both processes, heat is absorbed from the environment. You could record the temperature change using a thermometer or by feeling the reaction with your hand. The reaction between citric acid and baking soda is a highly safe example of an endothermic reaction, commonly used as a chemistry demonstration. Demonstration Do you want a colder reaction? Solid barium hydroxide reacted with solid ammonium thiocyanate produces barium thiocyanate, ammonia gas, and liquid water. This reaction gets down to -20Â °C or -30Â °C, which is more than cold enough to freeze water. Its also cold enough to give you frostbite, so be careful! The reaction proceeds according to the following equation: Ba(OH)2.8H2O (s) 2 NH4SCN (s) Ba(SCN)2 (s) 10 H2O (l) 2 NH3 (g) Materials 32g barium hydroxide octahydrate17g ammonium thiocyanate (or could use ammonium nitrate or ammonium chloride)125-ml flaskStirring rod Instructions Pour the barium hydroxide and ammonium thiocyanate into the flask.Stir the mixture.The odor of ammonia should become evident within about 30 seconds. If you hold a piece of dampened litmus paper over the reaction you can watch a color change showing that the gas produced by the reaction is basic.Liquid will be produced, which will freeze into slush as the reaction proceeds.If you set the flask on a damp block of wood or piece of cardboard while performing the reaction you can freeze the bottom of the flask to the wood or paper. You can touch the outside of the flask, but dont hold it in your hand while performing the reaction.After the demonstration is completed, the contents of the flask can be washed down the drain with water. Do not drink the contents of the flask. Avoid skin contact. If you get any solution on your skin, rinse it off with water.
