Chapter 11The Place of Study in Sadhana · The Study of Logic
Book 2. Part One: Sadhana on the Level of the Mind · Section Two: Cultivation of the Mind in Yoga
It [the study of logic] is a theoretical training; you learn by it some rules of logical thinking. But the application depends on your own intelligence. In any sphere of knowledge or action a man may be a good theorist but a poor executant. A very good military theorist and critic if put in command of an army might very well lose all his battles, not being able to suit the theories rightly to the occasion. So a theoretical logician may bungle the problems of thought by want of insight, of quickness of mind or of plasticity in the use of his capacities. Besides, logic is not the whole of thinking; observation, intuition, sympathy, many-sidedness are more important.
* I never heard that learning logic was necessary for good expression. So far as I know very few good writers ever bothered about learning that subject.
* I am not aware that by learning logic one gets freed from physical things. A few intellectuals lead the mental life and are indifferent to physical needs to a great extent, but these are very few.
* Common sense by the way is not logic (which is the least common-sense-like thing in the world), it is simply looking at things as they are without inflation or deflation — not imagining wild imaginations — or for that matter despairing “I know not why” despairs.
