No one can tell another person in any definite way how he should think, any more than how he ought to breathe or to have his blood circulate. ... The person who understands what the better ways of thinking are and why they are better can, if he will, change his own personal ways until they become more effective; until, that is to say, they do better the work that thinking can do and that other mental operations cannot do so well.
