 All these requirements can be found in the passage above. What we want to know counts as the cognitively measurable (“such a variety of things”). These knowables span items in the natural world and the cultural sphere and their features, as well as concepts in the realm of thought itself. The “concept, measure, or exemplar” is the qualitative norm the mind employs and of which it is the source. The mind does the actual measuring (“measures by itself”) and “makes itself a measure” or norm in judging and taking the measure of each item across the range of things it knows. What results is the knowledge we obtain when the mind becomes “equal to such a variety of things” and “attains itself in everything.” Our knowledge includes what we gain from everyday experience in society, from the natural and human sciences, and from literature and the other arts.
