Invalid Concepts

  • Introduction to Objectivist Epistemology
    The formation of introspective concepts follows the same principles as the formation of extrospective concepts. A concept pertaining to consciousness is a mental integration of two or more instances of a psychological process possessing the same distinguishing characteristics, with the particular contents and the measurements of the action’s intensity omitted — on the principle that these omitted measurements must exist in some quantity, but may exist in any quantity (i.e., a given psychological process must possess some content and some degree of intensity, but may possess any content or degree of the appropriate category).
  • For the New Intellectual
    No concept man forms is valid unless he integrates it without contradiction into the total sum of his knowledge.
