Rationalist refers to a type of thinking about organization, and autonomous humans choice, based on Kantian philosophy. It is also referred to as rational choice thinking and is based on the Kantian rationalist causality. See organization for a description of this type of thinking and other types.

Rationalism is a doctrine that reason alone is the source of knowledge and is independent of experience. Rationalists accept reason as the supreme authority in matters of opinion, belief, or conduct. Kant's dualism, of two causalities, views humans as independent agents having rational choice, while nature ruled by formative causality. See causality. Rationalists stand in contrast to empiricists.
