摘要
Nowadays the answer to the question ＂what is logic？＂ seems very simple and obvious--＂logic is a science,＂ and after that usually one says what is this science about. As for the expressions ＂logic is an art＂ or ＂the art of logic,＂ then they are only metaphors or some kind of ＂facon de parler＂ used in serious scientific discourse. One of my aims here is to trace （on the base of as authentic texts as a commentator literature） the line of development of dichotomy ＂logic as an art--logic as a science＂ and to demonstrate that both these feat uses of logic have fundamental historical roots and play very important conceptual role in any theorizing about logic. Despite the fact that （modern） logic is undoubtedly a science, it can be interpreted as an art, moreover, the analysis of logic from this point of view expands, it seems to me, the researching possibilities in the field of the philosophy of logic at least in better understanding what is logic, what creates its unity independently from the historical period of its development, topics, and methods.
