Humes Theory of Cause and Effect

Humes Theory of Cause and Effect Poyan Keynejad When discussing Humes account of cause and effect, various influences are interpreted in this relationship. Hume explains how cause and effect tend to come in sequences, as in trains of thought consisting of ideas, necessity, and skepticism. These three ideas explain the pinnacle of Humes cause and effect theory. When discussing ideas, one must consider the fact that ideas range from death-defying to enlightening. For example, when Hume discusses ideology, he mentions a golden mountain. When we think of a golden mountain, we only join two consistent ideas, gold and mountain. All of our ideas or more feeble perceptions are copies of our impressions or more lively ones. (Hume 212) Hume only says that whenever there is an idea, there will be a compounded thought process which reflects whether this idea is beneficial or negligible. (Hume 214) For example, when a mastermind robber, plans to rob a bank, he refers to a process in which his ideas are portrayed physically or visually, then le ads to a scenario of what ifs? These ideas or What ifs? are usually derived as a cause and effect of certain ideas. When referring to the bank robber, what if a meticulous layout of laser security or armed forces? What would happen if he was apprehended? These are usually questions that are asked when ideas when associating ideas with cause and effect. When referring to necessity, one must understand the definition of necessity: a condition or set of circumstances, such as physical laws or social rules, that inevitably requires a certain result. Hume addresses the problem of how liberty is intertwined with metaphysical necessity Hume believes that arguments on necessity and liberty are based on a lack of prior agreement on definitions. Necessity contributes to Humes thought processes in which human nature springs from a certain regularity that we observe in human behavior in all sorts of circumstances. (Hume 222) For example, when referencing a need, some may introduce nourishment and shelter, while others require love and understanding. With necessity, Hume assumes liberty as actions acted upon necessity (Hume 230). So with liberty, how can one differentiate the difference between liberty or necessity? This argument creates a conundrum which Hume himself creates an ideal that necessity may drive an individual to a cause and effect state. Last, when referring to skepticism, one must understand that it is in every possible situation that creates a state of anxiety or nervousness. This quote clearly explains skepticism, We need only ask such a skeptic, What his meaning is? And what he proposes by all these curious researches? He is immediately at a loss, and knows not what to answer a Pyrrhonian cannot expect, that his philosophy will have any constant influence on the mind: or if it had, that its influence would be beneficial to society. On the contrary, he must acknowledge, if he will acknowledge anything, that all human life must perish, were his principles universally and steadily to prevail.(Hume 226) Hume discusses the purpose of the situation. Along with that, he implicates that there should be a definite answer: Simply a cause and effect with proof. Another quote explains When we run over libraries, persuaded of these principles, what havoc must we make? (Hume 238) For example, if there cause of an incident, should there be a solution? Humes refers to havoc as an analysis of a problem, referring to its cause and effect, and introducing a solution. When referring to cause and effect, skepticism plays a significant role due to any actions made. Group II: Churchland Eliminative materialism is the radical claim that our ordinary, common-sense understanding of the mind is deeply wrong and that some or all of the mental states posited by common-sense do not actually exist (Churchland 287). In short, Churchland believes that humans were wrong about a lot of situations, that there is no plausible reason to believe it. One might also gripe that the theory is over optimistic about future of eliminative materialism. Churchland critically plays the role of hypocrite to his own belief, but in reality, eliminative materialism is farfetched idea which compares to witch-craft. The theory has a high sense of doubt not because the prospects for a materialist account of our mental capacities were thought to be poor because it seemed to disorient the logic of those who believe in this theory. Churchland in his article summarizes how common-sense psychological framework is a false and radically misleading conception of the causes of human behavior and the nature of cognitive activity. The initial plausibility of this rather radical view is low for almost everyone, since it denies deeply entrenched assumptions (Churchland 288). Churchland reinforces these statements by quoting, Eliminative materialism does not imply the end of our normative concerns. It implies only that they will have to be reconstituted at a more revealing level of understanding, the level that a matured neuroscience will provide. Thus, we must be careful not to indulge in the denial of the antecedent of a conditional (Churchland 289). Essentially the explanation is whittled down to where if folk psychology is true, then human obey certain ideal; if folk psychology is falsified; humans do not obey these ideals (Churchland 290). This logic is very skewed and creates a very confusing thought process. Essentially there is no questioning process, only a cut-and-dry thought process. Therefore the point of eliminative materialism is that categorization of mental states according to our ordinary, everyday understanding is illegitimate, because it is not supported by the best scientific taxonomies that deal with mental life, such as neuroscience. Some eliminative materialist authors add the further claim that future neuroscience will, in fact, eliminate all non-scientific vocabulary related to the domain of mental states (Churchland 289). When contemplating how eliminative materialism is actually viable, and someone provides low-quality proof, there must be some doubt. Churchlands article was very inconsistent and produced contradictions and a skewed sense of logic. Group III: Parfit Derek Parfit proposed that we separate the notions of identity and survival. In regards to identity he questions the how personal identity must have a definitive answer. He may sometimes explain how some of have an insufficient amount of personal identity, which would present a problem given certain criteria. Along with that, he explains how personal identity is of critical importance; When referring to the previous statement, one must have an established state of personal identity. (Parfit 353) His idea of importance toward an individuals identity makes complete sense, yet compromises a number his thoughts with illogical ideals. When regarding survival, he explains how survivability does not depend on an identity. While his ideas on identity make sense, he is not very persuasive when it comes to survivability. When an individual develops an identity, they usually have a certain stigma that follows them; i.e educator, enforcer, nurturer. Parfit indicates how the question of personal identity is not really that critical to an individuals lifestyle. (Parfit 354) To establish his theory on identity Parfit asks the reader to imagine a case of fission, where a mans brain is split into two and both halves are separately transplanted into two waiting, brainless bodies, On the assumption that both resulting people have my character and apparent memories. (Parfit 355) When thinking about this situation, brain removal usually means tantamount death on both sides of the human, but when speaking metaphorically Parfit believes that two individuals are conclusively different. In regards to the splitting of the human brain he summarizes If all the possible answers are implausible, it is hard to decide which of them is true, and hard even to keep the belief that one of them must be true. (Parfit 356) Parfi t indicates how the implications of personal identity are far ranging, and there is no definitive answer, post-experiment. It seems proper that if Parfits hypothesis is correct on self and identity, our inherited metaphysical schemes collapse. (Parfit 360) In regards to survival, Parfit believes that survivability can be possible without a personal identity. He states that, You could be two bodies with a divided mind. (Parfit 353) Essentially he implies that if the brain is split into two different entities, with a proven stream of conscious, that there are two separate identities. When incorporating these entities into survival, Parfit believes that these entities do not attribute to the success into survival, but the relation to a degree. (Parfit 354) When identifying survival, Parfit approaches the situation in a third person perspective. He doesnt account for someones life, abilities, identity, hopes, or dreams. Parfits theory of survivability incorporates some logic, but the line is crossed when survivability is not accounted for. Parfit needs to supplement his account by saying to what degree these psychological connectedness must obtain in order to count as survival, or his theory predicts that one can survive as another person without dying. His idea on survivability retains a very inconclusive point of view, which remains to be unpersuasive.

Erik Erikson’s Eight Developmental Stages Essay

Development theories are psychological stages of life. Erik Erikson is best known for his stages of psychosocial development and coining the term ‘identity crisis’. Erikson’s theory of psychosocial development is one of the best known theories of personality. Though similar to Freud, Erikson believed that personality develops in a series of 8 stages. Unlike Freud’s theory of psychosocial stages, Erikson’s theory describes the impact of social experiences across the whole lifespan. Erik Erikson’s Eight Developmental Stages Erik Erikson is one of the best known neo-Freudians in psychological history. He Grew up in Europe and spent most of his young adult life under the direction of Sigmund Freud. Erikson’s psychosocial development model was heavily influenced by Freud, and shares a number of central ideas from Freud’s psychosocial development theory. Instead of five stages, like Freud, Erikson came up with eight stages. The first stage, known as trust vs. mistrust, focuses on birth to roughly 18 months. Erikson also referred to infancy as the Oral Sensory Stage, which is the term Freud used for his first stage. The major emphasis on this stage is the parent-infant relationship. If the parent was nurturing and loving, the infant would gain trust in the parent and vice versa. Erikson said that: â€Å"Hope is both the earliest and the most indispensable virtue inherent in the state of being alive. If life is to be sustained hope must remain†¦Ã¢â‚¬  (Cherry, 2013). The second stage is autonomy vs. shame and doubt which is characterized by self-control, courage and will. The general age is about 18 months to two or three years old. Children learn to master basic skills such as using the ‘potty’, walking, talking and feeding themselves. If children master these skills, they build a sense of confidence and autonomy. One of the worst skills a child learns during his or her â€Å"Terrible Two’s† is the ability to use the powerful word, â€Å"NO!†. If shamed in the process of mastering a skill or potty training, children tend to feel a sense of guilt and doubt;  therefore, lowering self-esteem. From roughly three to five years old, children tend to observe and mimic adults around them and take initiative in creating play situations. This is the third stage, also known as initiative vs. guilt. The child strives to gain the ability to do things on his or her own, such as dress him or herself. If â€Å"guilty† about making own choices, the child will experience guilt and won’t function well. The fourth stage is industry vs. inferiority. This is â€Å"school-age†, usually six to twelve years old. ‘Child compares self-worth to others, such as in a classroom environment’ (Wikipedia, 2013). ‘At this stage, we are capable of learning, creating and accomplishing numerous new skills and gaining knowledge, thus developing a sense of industry’ (Harder, 2002). If we feel inadequate and inferior among our peers, we can experience serious issues in terms of competence and self-esteem. In the fifth stage, development depends primarily upon what the child does and what is done to the child. Life is now definitely getting more complex as the child attempts to find his or her own iden tity, struggle with social situations, and grapple with moral issues. The age range is from about twelve to eighteen years old. This stage is known as identity vs. role confusion. This is also where the child tries to find him or herself and figure out his or her own identity. The sixth stage of Erikson’s psychosocial development theory is intimacy vs. isolation. The average age is 18 to about 25 or 30. The young adult tries to find long lasting love and have mutually satisfying relationships with family and friends. Adults in this stage tend to generally begin to start a family. ‘If negotiating this stage is successful, we can experience intimacy on a deep level’ (Harder, 2002). The seventh stage is generativity vs. stagnation. This is during middle adulthood from about 35 to 65 years old. This is where work is one of the most crucial things in an adult’s life. ‘Strength comes through care of others and production of something that contributes to the betterment of society†¦Ã¢â‚¬â„¢ (Harder, 2002). This is what Erikson called generativity. This stage is also notorious for the â€Å"mid-life crisis†. This basically means that once the adult’s child or children has gone off and flew the coop, the parent now has to find new priorities to tend to and struggle with finding new meanings and purposes. ‘If a person is not comfortable with the way their life is progressing, they’re usually  regretful about the decisions and feel a sense of uselessness’ (Wikipedia, 2013). This is what Erikson called stagnation. The last stage of Erikson’s development theory is ego integrity vs. despair. The adult is usually about 65 and it goes all the way to death. The individual has now reached the last chapter in their life. Retirement is steadily approaching his or her way or has already taken place at this time. Many have achieved what was important to them like graduating high school and college, getting married, raising a family and retiring from a great job. If the individual feels like he or she has done nothing with his or her life, a sense of despair will con sume him or her. If he or she feels very positive about looking back on life, he or she will feel a sense of integrity. Erik Erikson’s psychosocial development theory is one of the best known stage theories in the psychology world. It does a great deal of explaining why humans act the way they act and why they are who they are. References Cherry, K. (2013). Erik erikson quotes.

Genetic Engineering The Next Technological Leap or a...

While walking down the produce aisle at your local grocery store, have you ever questioned where the assortment of goods came from? When asked, perhaps your first thought would likely be from a local farm or orchard. But what if I were to tell you that those very goods could in fact be from a far less obvious third choice? What if someone told you that those pretty peaches on display were meticulously grown in a laboratory to bring forth predetermined traits? As futuristic as it may sound, this type of technology is no longer science fiction but has become a new reality. Genetic engineering is a type of science defined as the deliberate modification of characteristics of organisms by manipulation of genetic material. This emerging†¦show more content†¦Even hydrocarbons are on the verge of being biologically engineered by manipulating one of the oldest living organisms on the planet, algae. Using only photosynthesis as a source of power, this discovery would revolutionize the oil and gas industry, making it safer and cleaner for the environment. Many national organizations are actively endorsing the publication of genetic engineering. Two non profit organizations linked to promoting the continual education and advancement of genetics are the American Society of Human Genetics, founded in 1948, and the Genetic Society of America, which was founded in 1931. The point brought about by each organization is that communication among scientists and the public plays a key role in not only dispelling global fear about experimentation, but to furthering the cause in a manner that produces greater discoveries, and public genetic enlightenment. Those against the genetic engineering movement on the other hand doubt that such a powerful technology should even be brought to mainstream science, let alone practiced freely. Their belief stands that even experimentation can not be done suitably without dire consequences. Some common arguments amongst opponents of genetic engineering are the morality of human genetic manipulation, the beginnings of human inequality, and unforeseen consequences of trialing in plants.
