Most people know nothing about psycho-epistemology. They take their habitual
method of thought for granted, leaving it unidentified and unquestioned. Yet
this kind of ignorance can be disastrous. . . . Men can automatize wrong methods
of thought without even knowing it. In order to achieve intellectual control,
therefore, in order to enjoy the full power over your mind that volition makes
possible, you must identify your psycho-epistemological methods, and correct
those, if any, which are not consonant with your adult knowledge.
This is a crucial discovery of Miss Rand’s—the discovery of
psycho-epistemology, and of its roots, forms, and errors. Without such
knowledge, men would be left at the mercy of unidentified mental habits that
they hardly even suspected—habits that perhaps derived unknowingly from
childhood errors that they long since had consciously renounced.
Psycho-epistemology represents a whole science, a new branch of psychology.
