Personal Identity in Whitehead's Philosophy of Organism - Personal Identity in Whitehead's Philosophy of Organism ABSTRACT: The focus of this paper is personal selfhood and personal identity in the philosophy of Alfred North Whitehead. Whitehead’s theory of human personhood is formulated within the fabric of his highly original western metaphysical vision. Rejecting the Aristotelian doctrine of substantive being, Whitehead embraced instead an ontology of becoming that sought to categorize the things of this world within a naturalistic continuum. His understanding of human selfhood was therefore explicated in terms of this continuum and avoided both the rhetoric and conceptualization of substance philosophy....   [tags: Whitehead Philosophy of Organism]

Many of his understandings of society expressed themselves in relation to the body. "The mind, as well as the body“, he wrote, “has its needs: those of the body are the basis of society, those of the mind its ornaments", writes Rousseau (1913: 130). He talks of the "artificial body of the government" (1913: 53) and “the body of the nation" (1913: 29), "the body and each of its members" (1913: 29). He saw that the health of the social body depends on unity: "public enlightenment leads to the union of understanding and will in the social body: the parts are made to work exactly together, and the whole is raised to its highest power" (1913: 34)....   [tags: Sociology ]

Dichotomous Key - Dichotomous Key Prior to evolutionary theory, scientists relied on similarity of physical characteristics to classify organisms. An 18th century naturalist, Carolus Linneas, developed a taxonomic classification system. This hierarchical system divides organisms into 5 kingdoms. Organisms visible to the unaided human eye fall into the plant, animal, or fungi kingdom. Kingdoms are then divided into phylum. This division is based body type and skeletal organization.

History of Cloning - History of Cloning Although the word itself has only been around for only four decades, the idea of creating an organism identical to another has been around for centuries. Even nature has utilized this process. The actual process of artificially cloning has been around since before 1900s, even though it is heard of more often in the modern world. Cloning began in 1894 with the first clone of an organism. Hans Dreisch was able to clone a sea urchin, and his research led to Hans Spemann’s multiple attempts and successes of cloning throughout his science years....   [tags: Biology Medical Biomedical Clone]

Genetic Engineering - Genetic Engineering          Genetic engineering techniques should not be used to custom tailor children.  It is morally wrong because it overrides natural selection.  Humans should not have the right to play God.  It is also unfair for those who are born naturally.  Instead of allowing nature to decide, humans might choose what their descendants will be like.  Nature alone should be the judge of one's skin color and other features.  Genetic engineering should only be used for medical purposes.  Otherwise, it is unfair to those who do not have access to these procedures, while genetically designed people will have an advantage over those who relied solely on nature.  Thus, certain forms of genetic engineering should not be permitted.    Genetic engineering is a broad term referring to the alteration of an organism's genes in order to remove unwanted characteristics of the organism or to add desirable characteristics (Levine).  Genetic engineering has been applied to plants and animals for greater and more efficient food production ever since the agricultural revolution.  It is also used on humans in the medical industry.  Genetic engineering techniques are used to identify and treat certain diseases as well as aid doctors in creating custom made drugs for specific patients (Gorman 81).  While the applications of genetic engineering on humans is currently limited, genetic engineering has the potential to eventually be able to treat virtually every disease....   [tags: Exploratory Essays Research Papers]

Cloning - Cloning What is a Clone. A clone is a group of genetically identical cells. For example, tumors are clones of cells inside an organism because they consist of many replicas of one mutated cell. Another type of clone occurs inside a cell. Such a clone is made up of groups of identical structures that contain genetic material, such as mitochondria and chloroplasts. Some of these structures, called plasmids, are found in some bacteria and yeasts. Techniques of genetic engineering enable scientists to combine an animal or plant gene with a bacterial or yeast plasmid....   [tags: essays research papers] 957 words

Pesticides - . Genetic engineering involves the alteration of an organisms hereditary material in order to eliminate undesirable characteristics or to produce plants with more desirable characteristics. The splicing of genes takes place in order to combine traits that would be unlikely to occur together under ordinary circumstances. Practices that go back centuries, such as the use of microbes to make wine and cheese and the selective breeding of livestock and crops, are example of biotechnology. (Campbell, 1999) These, and other, procedures have relied on mutation and genetic recombination....   [tags: essays research papers] 936 words

Psi and Ontology - ... Furthermore, the emergence of the mind of the person is an epiphenomenon thereby making it an entity that is intrinsic to the brain in which it is encoded within biochemical reactions within the neurophysiological structures contained therein. Psi implies a type of dualism, or even a pluralism, in which a dual aspect of consciousness can be said to be tied to an underlying domain which extends into a unifying and fundamental spectrum. That being said, a thought, in the neurological sense, does not constitute the thing that does what could be a psychic function; rather, it is the thing that can be said to mediate it, thus, one can say one has a guiding and a doing aspect in which information impinges upon the brain of the person via this entity creating physical changes to the brain in such a way as to transfer information to it and vice versa....   [tags: Psychology] 2215 words
