Eight reasons for its study. =6. SUMMARY.= (1) The aspects of the mind are knowing, feeling and willing. The mind is a living unit and never knows without feeling in some way and willing to some extent. (2) What the mind _is_ must be answered by philosophy; what the mind _does_ by psychology and what the mind _knows_ by logic. Psychology treats of the mind as a whole, logic of the mind knowing, aesthetics of the mind feeling and ethics of the mind willing. Ethics answers the question, What is right? Aesthetics, What is beautiful? Logic, What is true? The standpoint of logic is not identical with any particular portion of psychology. The mind knows in two ways: (a) by intuition, (b) by thinking. Thinking is a process――thought a product. Logic deals indirectly with the former and directly with the latter. Generally speaking, logic is a systematic study of thought. For the logician thought has two sources: (a) his own mind and (b) spoken or written language. Because of the ambiguity of language logic has much to do with it as a faulty vehicle of thought. (3) Logic as a science makes known the laws and forms of thought and as an art suggests conditions which must be fulfilled to think rightly. Author. “Logic may be defined as the science of the conditions on which correct thoughts depend, and the art of attaining to correct and avoiding incorrect thoughts.” Fowler. In the fundamentals of logical doctrine present day logicians virtually agree. (4) Logic should stimulate the thought powers; secure correct and clear thinking; aid in the estimation of arguments; inspire definite, systematic procedure; demand lucid, pointed, accurate expression and be especially adapted to general mental discipline. Logic adds to our store of knowledge and develops a passion for the truth. =7. REVIEW QUESTIONS.= (1) Explain and illustrate the three ways in which the mind may manifest itself. (2) Illustrate the fact that the mind acts in unity. (3) Show briefly how logic is related to mental philosophy, psychology, aesthetics, ethics and grammar. (4) Illustrate the two ways of knowing. (5) Distinguish between thinking and thought. (6) Give a general definition of logic. Why is this definition unsatisfactory? (7) What are the two sources of thought? (8) Why are logic and language so closely related? (9) Give that definition of logic which best satisfies you. (10) Summarize the benefits which you hope to derive from your study of logic.
