Quote from ‘Definitions for Baldwin's Dictionary [R]’
Theory [—] An outline statement, presenting to contemplation a sort of ideal diagram, or construction, which is to serve to represent a series of facts, not as they first present themselves, but so as to render the relations between them comprehensible. Theory is used in opposition to fact, and also in opposition to practice.
