    • Category (Logic) One of the highest classes to which the objects of knowledge or thought can be reduced, and by which they can be arranged in a system; an ultimate or undecomposable conception; a predicament. "The categories or predicaments -- the former a Greek word, the latter its literal translation in the Latin language -- were intended by Aristotle and his followers as an enumeration of all things capable of being named; an enumeration by the summa genera i.e., the most extensive classes into which things could be distributed."

    • n category In logic, a highest notion, especially one derived from the logical analysis of the forms of proposition. The word was introduced by Aristotle, who applies it to his ten predicaments, things said, or summa genera, viz., substance, quantity, quality, relation, action, passion, where, when, posture or relative position of parts, habit or state. These are derived from such an analysis of the proposition as could be made before the developed study of grammar. The categories or highest intellectual concepts of Kant are: categories of quantity — unity, plurality, totality;categories of quality —reality, negation, limit between these; categories of relation— substance and accident, cause and effect, action and reaction; categories of modality —possibility, impossibility, actuality, non-actuality, necessity, non-necessity. Modern formal logic furnishes this list: qualities, or singular characters; simple relations, or dual characters; complex relations, or plural characters. Many lists of categories have been given not founded on formal logic.
    • n category A summum genus, or widest class.
    • n category Any very wide and distinctive class; any comprehensive division or class of persons or things.
