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]

The Usefulness of the Analogy Between Society and a Biological Organism - The Usefulness of the Analogy Between Society and a Biological Organism One set of sociologist that use the Biological or Organic analogy of societies are the Functionalists. Functionalism first emerged in Europe in the 19th Century. The French sociologist Emile Durkheim was the most influential of all the early functionalists. The theory became the dominant theoretical perspective in the 1940's and 1950. The functionalist theory is that within society there are many small parts that have to work together to maintain the society....   [tags: Papers] 890 words

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.

It is predicted that burrowing and the addition of feathers will both help maintain homeostasis through thermoregulation....   [tags: Biology] 918 words

Flagella are single, whip-like structures that propel an organism through an aquatic environment. They use undulatory motions, where the waves of motion start at the base of the flagellum. The size, the volume of the medium, the length, position and width of the flagella on the organism determine the direction and speed propulsion of the cell. There are three different types of flagella movement. They are either planar, oarlike beating, or three dimensional waves.In the three dimensional wave movement, the flagella whips back and forth....   [tags: essays research papers] 380 words
