The second day deals with the problem of concepts and Ayn Rand’s solution. After a brief survey of traditional theories, the instructor explains the role of measurement-omission and of the identification of essential characteristics in the formation of a concept, what it means to call a concept a “mental entity,” how concepts are based on evidence, the nature of definition and how Rand’s explanation of concept formation reflects her general conception of awareness as an active process.

This course includes a handout and transcript.
