ABSTRACT
This chapter focuses on the contrast between the concept of difference, in all its variety of meanings, and the cognitive primacy of contrariety. It provides the basis for a clear distinction among the meanings of the key terms, contradiction, privation, and contrariety. The chapter also aims to provide an exposition of the types of opposition, relate opposition to the direct contraries and contraries with intermediates, and establishes the rules concerning the logical relations of contrary statements. It discusses what seem to be Aristotle's philosophy of language and its relation to process. Aristotle discusses the meaning of difference, and then proceeds to consider contrariety, privation, and contradiction in the light of 'difference'. The chapter aims to establish contrariety as the grounds for the formulation of the law of non-contradiction and relate it to the understanding of being as process. The law of non-contradiction is the logical formulation of the principle of contrariety.
