Abstract: | Living organisms exhibit various levels of self-regulation, the highest of which is man's ability to regulate the operation of his conceptual faculty. Ayn Rand's theory of free will, the basis of this article, identifies this level of self-regulation with volition. The locus of direct volitional choice is placed in the choice “to think or not to think,” where thinking is understood as rational, purposefully directed cognition. The nature of this choice is analyzed in detail, with special emphasis on Rand's concept of mental “focus.” The epistemological status of the theory is discussed, including the role of introspective evidence in its behalf. It is argued that one's volitional control over one's own thinking has the status of an axiom, and that any attempted denial of this control is self-refuting. |
