The concept of logical thinking is selection and this is brought about by the processes of acceptance and rejection. Rejection is the basis of logical thinking.

Logic is immaturity weaving its nets of gossamer wherewith it aims to catch the behemoth of knowledge. When Logic comes of age it strangles itself in its nets and then becomes transmuted into Faith, which is the deeper knowledge. Logic is a crutch for the cripple; but a burden for the swift of foot; and a greater burden still for the winged.

It is with logic as it is with other sciences. They draw wisdom from the mysterious source of plain experience. Agriculture, e. g., aims to teach the farmer how to cultivate the soil; but fields were tilled long before any agricultural college had begun its lectures. In the same way human beings think without ever having heard of logic. But by practice they improve their innate faculty of thought, they make progress, they gradually learn to make better use of it. Finally, just as the farmer arrives at the science of agriculture, so the thinker arrives at logic, acquires a clear consciousness of his faculty of thought and a professional dexterity in applying it.

Thus arises the second tendency, which consists in regarding logical and mathematical relations as irreducible, and in making an analysis of the higher intellectual functions depend on an analysis of them. But it is questionable whether logic, regarded as something eluding the attempts of experimental psychology to explain it, can in its turn legitimately explain anything in psychological experience.

Whole object of intellectual education is formation of logical disposition

It may be true that only those minds which are habituated to think logically can safely trust their intuitive conclusions, on the theory that the subconscious level will do its kind of work as faithfully as the conscious does its kind.

Logic is the necessary product of intelligence and sincerity. It cannot be learned. It is the child of a clear head and a good heart.

The true function of logic ... as applied to matters of experience ... is analytic rather than constructive; taken a priori, it shows the possibility of hitherto unsuspected alternatives more often than the impossibility of alternatives which seemed prima facie possible. Thus, while it liberates imagination as to what the world may be, it refuses to legislate as to what the world is

His thinking wasn’t logical. But whatever the philosophers claimed, the main use of logic was to justify your emotions.

Classical logic believed it was possible to discover the actual structure of thought processes, and the general structures underlying the external world as well as the normative laws of the mind . . . As logic has perfected its formal rigor, logicians have ceased to interest themselves in the study of actual thought processes.

Few persons care to study logic, because everybody conceives himself to be proficient enough in the art of reasoning already. But I observe that this satisfaction is limited to one's own ratiocination and does not extend to that of other men. We come to the full possession of our power of drawing inferences the last of all our faculties, for it is not so much a natural gift as a long and difficult art.

LOGIC The principle governing human intellection. Its nature may be deduced from examining the following propositions, both of which are held by human beings to be true and often by the same people: “I can’t so you musn’t,” and “I can but you musn’t.”

Logic aims to instruct the human mind as to its own nature and processes; it will lay bare the interior working of our mind for our guidance. The object of the study of logic is thought, its nature, and its proper classification.
