Knowledge Essays (681 words) - Scientific Method, Free Essays

Knowledge Essays (681 words) - Scientific Method, Free Essays Knowledge is good for human being because I can use it to make anything to support my live better. However, knowledge is nothing to compare to imagination in human society. Imagination is used when I am curious about a problem, and I want to know and to understand how it happens. After I understand it, I put all its information into knowledge that can be easily understood for other people. If I put a condition or a rule into the imagination of a phenomenon, I have a hypothesis that guilds me understand the phenomenon deeply. A hypothesis is the first step to invest a phenomenon. A hypothesis helps me to focus on one path when I invest a phenomenon. During an investigation, I will discover many unexpected events that could distract my thoughts about my first goal, and I will waste more time. For example, my friend and I have a race to see who is first at home from our school, and he walks to home while I use a bike. The result is he wins. In my thoughts, walking cant be faster than a bike because I know the road well, so I want to know how he did it. I see three paths that are new roads in front of me when I walk to home, and I need to decide which path I go. On the chosen road, I see a walking path and a bike path, and there are many bikes to use if I chose bike path. If I use bike, I change the tool to go home from feet to bike, and it changes the purpose when I walk to home, so I keep walking. There is a new shortcut that is easy for walking to go straight to my house from the road, and it takes a long time if I use a bike. The hypothesis I make at the beginning is walk to home to see if its faster than a bike, and I prepared myself to have a solution for walking problems. Moreover, a hypothesis helps me to prepare many solutions if there is a problem in an investigation. To have a hypothesis in an investigation, I need to assume the problem behavior is similar to other problems I faced, so I can prepare better solutions. Back to the home walking example, I planned to walk home and chose one of three paths, so I need to make sure my safety because of the new path. During the time, I could observe the new environment to update my information. I guess my friend uses a shortcut to be faster than me, so I watch carefully around me and find one. That shortcut has a high rock wall that is hard to get through by a bike, but its easy for feet. If I dont have any hypothesis how my friend does it, I cant find the shortcut by observing everything on my path. In addition, a hypothesis helps an investor to have different views about a phenomenon. With different views, the investor can understand phenomenon more clearly and get a better picture about it. Back to my walking home example, I can see a shortcut easily because I assume there is one. However, if there isnt any shortcut, so I need to think any possible ways, such as the shortcut could be replaced by a very high wall or my friend goes through a house by back door. For each view, I need to examine to find an accepted solution how my friend can walk to home fast while I ride a bike. Indeed, a hypothesis gives an investor a first step of research, good preparations for investigations problems, and good views to understand a phenomenon deeply. A hypothesis could make a strange thought, but it could make an unexpected result that an investor tries to find. However, the investor needs to have a testable hypothesis rather than a fancy one. When the investor can prove his testable hypothesis, he has one step to get close to the phenomenons fact.

Free Essays on Call Of The Wild - Thematic Summary

More important than the actual events of the novel are many of the themes expressed throughout the story. These include Buck’s gradual transition from pampered housedog to powerful sled dog to wild beast, greed and the mistreatment of animals, loyalty and love, and even what "The Call of the Wild" actually means. Throughout the book, Buck would hear a howling from the woods, or saw visions of his ancestors in his sleep. He had looked into the campfire and seen back generations, to the wild dogs who were his ancestors, and the hairy men who were their masters. He recognized how their lives connected them. Something within him longed to return to the state that these ancestors lived in, to answer the call of the wild. As the novel continued, he had given into this call more and more often, and each time, to a greater extent. He experienced physical changes, such as the hardening of his muscles, and many emotional changes, the desire to join his wild brother, and the dislike for his former life in the Santa Clara Valley. At one point in the book, Buck leaned his head back and gave a long, low wolf howl. It excited him like nothing he had ever felt, and expressed the change he felt toward the wild beast. When Buck finally gave in to the call permanently, there was a sense that Buck had achieved the destiny that he was meant for, and that his primitive life would give him a happiness that he had never before experienced. Jack London showed greed in many ways. One was the mistreatment of the sled dogs, which showed how far a human would actually go to get what he wanted. These brutal men only wanted gold. The only reason they were in the Alaskan wilderness was for the riches that were spread amongst the treacherous terrain. The ideas of having money, and being wealthy were enough to force a man to beat a dog, as if the dog could feel no pain. All through the story, the sled drivers would starve their dogs, trying to force them to work h...

Internal Analysis using RBV of California Pizza Kitchen Essay

Internal Analysis using RBV of California Pizza Kitchen - Essay Example The internal analysis yielded interesting findings which can help the chain develop strategies to overcome its financial worries. The chain has experienced success abroad and should focus on its innovative pizzas, toppings and salads to increase customer base. Service in the USA needs to be improved and an increase in sales is necessary to reach performance objectives. Opportunities in the form of recovering economic conditions and an increasing trend to eat out will help the chain but it needs to augment its brand image. In order to increase the value of the firm, it is looking for sale and merger options which will help in salvaging shareholder wealth. California pizza kitchen may benefit from a merger or takeover but presently it needs to focus less on expansion and more on increasing sales at current outlets. Introduction California Pizza Kitchen was started in 1985 by lawyers Rick Rosenfield and Larry Flax. The Kitchen introduced pizza flavors from all over the world and focused on cooking in wood burning ovens, gourmet pizzas and creative salads. The chain is famous for its unique and innovative creations and has over 230 locations in the USA and nine other countries. CPK has also licensed to distribute CPK frozen pizzas in groceries and supermarkets. In 1992 Pepsi Co purchased 67% of CPK’s stock and undertook rapid expansion which resulted in high losses for the company. In 1997, Pepsi’s share was bought by a private equity firm Bruckmann, Rosser, Sherril and Company but the company’s performance did not improve. In 2003, the original duo regained control of the company resulting in an improvement in the company’s performance. . ...

California Pizza Kitchen: Financial analysis: The economic value of California Pizza Kitchen using the formula for economic value added and the inputs provided by wikiwealth.com (California Pizza Kitchen, 2010): NOPAT – c.K $ 19M- 0.09*285M = - $6.65 M The economic value added for the company is negative in 2010, which shows that the value is not being created and that the cost of capital is too high. A comparison with other competitors shows that although the industry WACC is also 9%, California Pizza Kitchen is not as leveraged as its competitors. The return on equity is -3% which is lower than the industry average on -6%. Revenue growth and profit margins stand around 9% lower than the industry averages of 11% but cash flow margin positive whereas the industry margin is negative. Revenue growth in the fourth quarter of 2009 fell by 5.8% and sales are expected to keep dropping till 2012.The financial performance of the company improved after 2003 but has deteriorated in recent years and it needs to focus on further revenue growth. Competitors such as Red Robin Gourmet Burgers and Texas Roadhouse are performing better financially but CPK falls in the middle of the pack and is performing much better than others with investors forecasting a potential increase of 45% in the enterprise value. (California Pizza Kitchen, 2010) Resources: The tangible resources available to the organization include its diversified and high quality menu that caters to different tastes. The pizza toppings and salads are a combination from

Energy Industry Essay Example | Topics and Well Written Essays - 1250 words

Energy Industry - Essay Example Alaska, California, Louisiana succeedingly ranked in its respective slate in 1989 for generating 41% of oil but have degraded its supply contribution to 17% of total oil output recently (Styles, 2013). This decline is supplemented with the development of extractive industry at New Dakota which replaced Alaska in 2012and is contributed further by Colorado, Oklahoma and New Mexico’s rigs (Styles, 2013). The risk however is showed by oil generation reduction when the principal pipeline of onshore oil production became a funnel for oil importation (Styles, 2013). There is imminent reduction of New Mexico’s oil supply too following the Deepwater Horizon incident in 2010 (Styles, 2013). Economists recognized that the challenged nowadays is how the oil supplies from the upper part of the country to be distributed in the regions needing more of oil supply efficiency for domestic market demands (Styles, 2013). Such meant that the company therefore should be re-strategizing its w ays to balance the distribution of oil from region with crude surplus to other areas by transporting or shipping the refined products via multiple tankers to the Midwest (Styles, 2013). Recognizing that there is reduced supply after more than two decades of extraction, the challenge on oil production and efficiency distribution is doubled, notwithstanding fact that there are Oil Companies now eyeing oil resource in Monterey deposit (Styles, 2013). Suffice it to say, there is further challenges in the participation of the states in the west coast and hence, economist purviewed that California, Oregon, Nevada, and Washington will be primordially affected when oil production and distribution disruption happens (Styles, 2013). As an adviser to the consultant of the oil industry sector, the following vulnerabilities are therefore significant for consideration: 1. Improving quality control for oil generation and control.- Oil companies have been confronting problems on facilities and pipe lines safety amid issues that have happened on leakage or destruction in some significant part of the generation or oil refinery plants that caused and cost significant amount of destruction. 2. Problems involving social acceptability of tapping oil reserves- Strong sentiments on climatic changes, environmentalism and protection of indigenous peoples rights, as well as strong presence of armed elements over their lands are major causes of resistance from regions where proposed tapping of oil reserves are abound. Company managers must look into these concerns and seriously deal states and communities in rigorous dialogues. They must also be ready of measures to prevent potential outbreak of violence. 3. Future oil production and distribution efficiency for the Midwest states. The significance of this matter is highly elaborated in the preceding paragraphs of this paper. 4. Adaptation to renewal energy. Review the capacity of renewable energy production of the country and valuate its supplementary contribution to meet the demands for energy for Midwest states. Evaluate if the states can opt to maximize the potentials of renewable sources of power and its feasibility to double or triple it adaption (Department of Energy, 2013). Concerns relating to climatic changes and weather patterns must be accounted for serious consideration too on how renewable energy be maximized in accord to weather

A Streetcar Named Desire by Tennessee Williams Essay Example for Free

A Streetcar Named Desire by Tennessee Williams Essay Over the last few lessons in drama we have been working on a number of tasks to do with Tennessee Williams A Streetcar Named Desire. These tasks involved using movement as well as words; some were naturalistic and others were much more abstract. Our first task was to walk like different characters from the play, focusing on the way they used certain parts of their body to show their personalities. First we had to walk like Stanley. Most of us walked with a confident swagger, sticking our chests or pelvises out to indicate his masculine pride. When we were asked to sit down in character, we sat back in a relaxed manner, opening our legs and perhaps loosely crossing our arms or draping them over the back of our chair, indicating total self-assuredness. Next we were asked to play Blanche. I decided to portray her as a fidgety person, constantly smoothing her clothes, fixing her hair or touching her face, to show her insecurities and lack of confidence. I also walked with short, dainty steps, to show how fragile and slight she is. When we sat down, I leaned forward slightly, with my shoulders slightly hunched, to show her vulnerability. Finally we were asked to portray Stella standing upright, slightly tense as if waiting to heed to Stanleys latest demands and Mitch big, awkward, slightly more hunched and less confident-looking than Stanley. After this task, we were asked to depict Stanley and Blanche as animals. For Stanley, nearly everyone acted like a wolf or a fox strong, territorial, sly, always hunting and watching. For Blanche, I chose to act like a small bird, which would preen and look pretty but would be fidgety and nervous and would fly away when frightened. Our next task was to get into groups and act out scenes taking place before the play begins, which would reveal something interesting about our characters. I was in a group with Emily, and we were told to act out a scene from when Blanche and Stella still lived at Belle Reve. Emily played Stella and I played Blanche. Our scene began with Blanche climbing through the window of the room she shares with Stella, late at night. Stella, who has been studying, admonishes her for being so late and tells her how worried she has been. Blanche, who has been drinking but claims she limits herself to one, has just met a young man who reads poetry, who, as we know, will later commit suicide. It is revealed that Stella is the clever sister, who has the potential to make something of herself, and Blanche is the wilder, worldlier sister who relies on her beauty to have fun. This explains why Stella left Belle Reve and had the ability to get a husband and a home of her own, and why Blanche was left be hind, unwilling to grow up and surrender her beauty. Millie and Genna also played Blanche and Stella at Belle Reve. Their scene involved Blanche taking Stella out on the town for the first time. Blanche is very domineering and worldly, and Stella is naà ¯Ã‚ ¿Ã‚ ½ve and nervous about the shortness of her dress. Stella wears white, showing her innocence, and Blanche wears red, showing her corrupted virtue. Jack and Owen played Mitch and Stanley. They gave Mitch a deep personality, having him hint about wanting to settle down with a wife and worrying about his mother. They also showed Stanleys love for Stella, as he talks about her in a very loving and tender way to Mitch. Next Felix and Flick, playing Stanley and Stella, showed how Stella was very like Blanche when she first met Stanley, unused to this more working class environment, yet being excited by Stanleys attentions. Finally, Angelika and Hugo, playing Stella and Stanley, show Stella as being naà ¯Ã‚ ¿Ã‚ ½ve and Stanley being mysterious and inquisitive, trying to figure her out . In our next task we did Hot Seating. One by one, we were asked questions in character about our views on different events in the play. I chose to be Eunice, because although she is not a main character in the play, she is good friends with Stella and her husband is friends with Stanley, and she lives in the flat above them, so she would have a very clear idea of what life would be like for them. I chose to give her the opinion that Stanleys hitting Stella isnt good, but is acceptable, and is just a part of marriage that cannot be avoided. I was particularly impressed by Emilys portrayal of Stella after having her sister taken away. She made it clear that Stella was heartbroken, and although she claimed to believe Stanley, she let on that she had no choice but to believe him. I also liked Alex as Blanche, gushing and acting pleasant and sweet to try and cover up her past, but when difficult questions were brought up her act fell and she would refuse to talk about it. Our final task was to act out the scene where Blanche has been stood up by Mitch on her birthday and use freeze-frames to mark the most important moments in that the scene. I was in a group with Felix and Alex. Felix played Stanley, Alex played Blanche and I played Stella. The moments we marked were: Stanley throwing plates off the table; Stella and Stanley on the porch with Blanche on the phone, trying to reach Mitch; Stanley giving Blanche a ticket back to Laurel; and Stella going into labour. For each of our important moments, we froze in position for four seconds, before doing an action and moving onto the next moment. There were subtle differences between each groups piece; instead of using an action, as we did in ours, Millie, Flick and Jack used an important line of text in each of their moments, which I found very effective. Although I found these tasks challenging (especially as I knew we were on camera), I enjoyed interpreting different characters in new ways. I also worked with different people to whom I normally would, which was a good experience and made me enthusiastic and eager to work with them again in future lessons.

Honda CRX :: miscellaneous

Honda CRX The CRX has been a vehicle way ahead of its time and a best seller for Honda for over twenty years since it was first introduced in 1985. It was inevitable from the start that there would be a reintroduction of one of the most sophisticated models ever introduced by Honda. Honda for over ten years has been seriously considering the redevelopment into the new concept version of the CRX. This vehicle would have similar past qualities, such as being a two seated hatchback and containing a spacious and luxurious interior as well as incorporating the technology of the future. The early models of the CRX were split into two generations, the reintroduction being the third generation. The first generation manufactured in 1985 until 1987 featured new technology and styling never before seen on the automotive market. Introduced with three sub models the HF, DX, and SI, all contained different engines, transmissions, styling, and performance specifications as shown on the chart enclosed. This first generation CRX was an odd addition to the car market due to their compact size and all around exterior â€Å"boxy† look. The second generation introduced in 1988-1991 was also broken off into three sub models due to performance enhancements. The exterior was sti ll the basic box shape, but with a more sleek and appealing body style than of its first generation production. The new CRX concept vehicle, being the third generation, will contain major upgrades while still trying to keep the ingenious styling of past generations. The exterior will still contain the basic two door hatchback look, but will incorporate a more flowing and curved body style, leaving the boxy look of the past behind. The biggest upgrade of the CRX would have to be its engine. While more economical than in the past, it will also be a more desired engine for sport compact enthusiasts. Honda will be leaving behind the standard 1.5 liter contained in all past generations and will be offering two sub models, each containing a different engine. The entry level vehicle will contain a 1.0 liter DOHC (dual overhead cam) VTEC housed in a three cylinder base, producing anywhere from 85-100 horsepower. The upgraded version will contain a very awaited and anticipated 1.6 liter DOHC VTEC in a four cylinder base producing about 150-200 horsepower. These numbers to most seem very low, but are very surprising when considering the overall weight distribution of the vehicle is only 1762.

The Men We Carry in Our Minds

The Men We Carry in Our Minds Scott Russell Sanders In his essay â€Å"The Men We Carry in Our Minds,† Scott Russell Sanders examines the problems that exist between gender inequalities. These problems mainly took place during the early 20th  century. Men had the choice of either being factory workers or soldiers, while women only had the option of staying home. Sanders uses  argumentative strategies  to help the reader establish and see clearly the difficulties between this issue.His essay expresses how only certain men were forced to do hard labour in order to provide for their family, while others just had it handed to them. He also argues about how women were never given the equal opportunity to follow their dreams and were told that only men were capable of being successful. As a child, Sanders witnessed many men go through the same routine of life, being forced to do hard labour in order to support their families. He knew men such as marginal farmers, carpenters, s teel workers and many others who all laboured with their bodies.But he also knew of another sort of men, â€Å"†¦ men, who did not sweat and break down like mules† (Sanders, 326). These other sorts of men were soldiers. To Sanders they appeared like they barely worked at all. But he later learned that these men would soon be off to war, to fight for their lives and for their country. At first, appearance meant everything but later Sanders learned that it wasn’t just hard working men who had hardship, every man did. Sanders was given an opportunity that many in his social class were rarely given.He was offered a scholarship into college, which taught him the different views of people towards life. Being in college allowed him to interact with different types of people, especially women and these interactions opened his views into the issues that concerned many women. He learned how women were tired of always being in the shadow of men, and that they wanted to be re cognized as their own individuals. Sanders soon realized that the main influence towards these women views were the men in their lives.The fathers who brought them up and taught them that only men were capable of being successful. Women strongly believed that they had equal rights of being as successful as men. From the interactions with women around him, Sanders finally realized that women were just as equal, but to society it was still the same. In the end men were to be seen more successful than women.

Solubility Definition in Chemistry

Solubility Definition in Chemistry Solubility is defined as  the maximum quantity of a substance that may be dissolved in another. It is the maximum amount of solute that may be dissolved in a solvent  at equilibrium, which produces a saturated solution. When certain conditions are met, additional solute may be dissolved beyond the equilibrium solubility point, which produces a supersaturated solution. Beyond saturation or supersaturation, adding more solute does not increase the concentration of the solution. Instead, the excess solute starts to precipitate out of solution.​ The process of dissolving is termed dissolution. Solubility is not the same property of matter as the rate of solution, which describes how quickly a solute dissolves in a solvent. Neither is solubility the same as the ability of a substance to dissolve another as a result of a chemical reaction. For example, zinc metal dissolves in hydrochloric acid through a displacement reaction that results in zinc ions in solution and the release of hydrogen gas. Zinc ions are soluble in acid. The reaction is not a matter of the solubility of zinc. In familiar cases, a solute is a solid (e.g., sugar, salt) and a solvent is a liquid (e.g., water, chloroform), but the solute or solvent may be a gas, liquid, or solid. The solvent may either be a pure substance or a mixture. The term insoluble implies a solute is poorly soluble in a solvent. In very few cases is it true no solute dissolves. Generally, an insoluble solute still dissolves a little. While there is no hard-and-fast limit that defines a substance as insoluble, its common to apply a threshold where a solute is insoluble is less than 0.1 gram dissolves per 100 milliliters of solvent. Miscibility and Solubility If a substance is soluble at all proportions in a specific solvent, it is called miscible in it or possesses the property called miscibility. For example, ethanol and water are completely miscible with each other. On the other hand, oil and water do not mix or dissolve in each other. Oil and water are considered to be immiscible. Solubility in Action How a solute dissolves depends on the types of chemical bonds in the solute and solvent. For example, when ethanol dissolves in water, it maintains its molecular identity as ethanol, but new hydrogen bonds form between ethanol and water molecules. For this reason, mixing ethanol and water produces a solution with a smaller volume than you would get from adding together the starting volumes of ethanol and water. When sodium chloride (NaCl) or other ionic compound dissolves in water, the compound dissociates into its ions. The ions become solvated or surrounded by a layer of water molecules. Solubility involves dynamic equilibrium, involving opposing processes of precipitation and dissolution. Equilibrium is reached when these processes occur at a constant rate. Units of Solubility Solubility charts and tables list the solubility of various compounds, solvents, temperature, and other conditions. The IUPAC defines solubility in terms of a proportion of solute to solvent. Allowable units of concentration include molarity, molality, mass per volume, mole ratio, mole fraction, and so on. Factors That Affect Solubility Solubility may be influenced by the presence of other chemical species in a solution, the phases of the solute and solvent, temperature, pressure, solute particle size, and polarity.

Locate and Identify Black Locust in North America

Locate and Identify Black Locust in North America Robinia pseudoacacia, commonly known as the black locust, is a prickly tree within the subfamily Faboideae of the pea family called  Fabaceae and is considered to be a legume with flattened pea pods several inches long. Black locust is native to the southeastern United States, but has been widely planted and naturalized elsewhere in temperate North America, Europe and Asia. The original range of the locust is in the Appalachian, Ozark and Ouachita range  located in the middle mountains of Eastern North America.  They are now considered an invasive species in some areas even within the natural range. Black locust was introduced into Britain in 1636 where it has slowly garnered a universal appeal to tree lovers. Black Locust Identification One major identifier is the long compound leaves with up to 19 leaflets which present  the typical and unique locust leaf profile (not to be confused with the twice compound leaves of honey locust). The other ID marker is a small stout briar spine  on branches, often curved and in pairs at each leaf node. Late spring to early summer flowers can be showy, white and drooping  with 5-inch flower clusters. These flowers are fragrant with a vanilla and honey scent. The leguminous fruit developing from the flower has 4-inch papery thin pods with small, dark-brown, kidney-shaped seeds. These autumn seeds will persist until the next spring. You will find this tree primarily  in areas where it colonizes open fields and roadsides. Its ability to grow in poor soils, fast growth, ornamental foliage and fragrant flowers make for a favorite tree to plant. More on Black Locust Black locust is sometimes called yellow locust and grows naturally on a wide range of sites but does best on rich moist limestone soils.  Black locust is not a commercial timber species but is useful for many other purposes. Because it is a nitrogen fixer and has rapid juvenile growth, it is widely planted as an ornamental, for shelterbelts, and for land reclamation. It is suitable for fuelwood and pulp and provides cover for wildlife, browse for deer, and cavities for birds. We must recognize that black locust is not an important tree for logging purposes as there is very little timber value and it has little lumber or paper pulp potential. We still need to remember that the tree has and is used  in the United States to be manufactured into a wide variety of products. Robinia pseudoacacia is planted for many specialized purposes. Black locust is used for fence posts, mine timbers, poles, railroad ties, insulator pins, ship timber, tree nails for wooden ship construction, boxes, crates, pegs, stakes, and novelties. Pulp with satisfactory mechanical properties can be made from the tree, particularly by the sulfate process but commercial value awaits  further investigation.

Euro Essay Example | Topics and Well Written Essays - 250 words

Euro - Essay Example They introduced the Euro in non-physical electronic form at midnight on 1 January 1999. At that time, the national currencies of participating countries ceased to exist. Nevertheless, they continued as legal tender until new euro notes and coins were introduced on 1 January 2002. The changeover period lasted until 28 February 2002. The purpose of the Euro was to solidify the European economy as a whole (Gerlach and Svensson 2003). Differences cause by rounding and the use of significant digits made international trade difficult on the subcontinent itself. Plus, the institution of a unified mode of exchange augmented trade outside Europe. As a result, the European economy has become stronger both internally and externally. Compare the performance of the Euro to the U.S. dollar, for instance (Portes et al 1998). From the start, the Euro represented about one and a half times the value of the U.S. dollar. Although it has risen and fallen over the last decade, it has always remained competitive and never sunk below the value of a U.S. dollar. This indicates a robust global presence on part of the Euro. It will be interesting to observe the impact of the Euro on stabilizing our current global recession. References and further reading may be available for this article.

The Argument Against the Existence of God Essay

The Argument Against the Existence of God - Essay Example The theologian embraces three propositions - God is omnipotent, God is good and evil exists. Mackie's brilliant argument for the problem of evil has shown that the first two propositions cannot be true while the third exists. He has made use of two additional premises to drive the point home. He calls these "quasi-logical rules connecting the terms 'good', 'evil', and 'omnipotent'" (Mackie 78). These additional propositions state that good is in a state of opposition with evil and seeks to eliminate it and that omnipotence is without limits. Therefore Mackie's argument and the problem of evil has decimated the very core of theistic belief by claiming that "the several parts of the essential theological doctrine are inconsistent with one another, so that the theologian can maintain his position as a whole only by a much more extreme rejection of reason" (Mackie 77). Thus his argument calls for a complete reconstruction of the theological doctrine as we know it. At the onset Mackie outlines certain adequate solutions to the problem of evil that is also consistent with the essential theistic propositions or which rejects one or more of the propositions. He makes it clear that only those who believe that God is omnipotent and wholly good are confounded by this problem. ... Mackie then turns his attention to four solutions that he calls fallacious because they overtly adhere to the integral theological propositions while inadvertently or covertly rejecting one or more of them while attempting to tackle the problem of evil. The first of these fallacious solutions is that it is not possible for good to exist without evil. Mackie asserts that this solution does explain away the presence of evil but a whole series of problems crop up consequently. For instance it questions God's omnipotence because it implies that God cannot create one without the other and is invariably bound by the rules of logic. Further this solution undermines God's goodness as it appears that God is not opposed to evil if it is deemed necessary. Besides, the existing evil is far in excess of the amount needed to serve as a mere counterpart to good. Some people claim that evil is necessary as a means to good. This view according to Mackie contradicts the theist's view of God's omnipotence as it suggests that God's power is subject to the law of cause and effect. Therefore this argument as seen by Mackie does not hold much water as it severely detracts from God's omnipotence. The third solution to the problem of evil is that the world with its attendant evil is a better place than one without. By way of explanation Mackie classifies good and evil into levels. He calls pain and other forms of physical discomfiture first order evils whereas pleasure constitutes first order good. First order evil is necessary to bring out second order goods like benevolence, courage, fortitude and the like which far outweighs first order evils. But Mackie states that this argument falls apart as it does not take into
