Nature of categorization Predominant principles in logical categorization, family resemblances and prototype theory

One of the most basic and efficient abilities of human mind in recognizing phenomenon is categorization. It means putting similar phenomenon in general groups in order to ease recognition of their examples. Categorization could be investigated by three approaches. Aristotle or classical logic is the oldest method of categorization which is based on principles of subjectivism, necessity of common element in examples, maximum discrimination, simplification, determination of categories and same gradation. Second approach in categorization is based on Wittgenstein’s familial resemblance. Main principles of this method are as follows: objectivism instead of subjectivism, familial resemblance instead of common quiddity, fuzziness instead of maximum discrimination, negation of apparent category determination and grading examples instead of same grade. The most exquisite method of categorization is cognitive categorization that emphasizing the prototype element in process of categorization differs from the two previous methods in empiricism principles against objectivism and subjectivism also prototype against common quiddity.
