The Commens Dictionary
Quote from ‘Logical’
Logical definition. A strict definition by genus and specific difference. Ockham and his followers objected to the designation on the ground that the logician, as such, had no occasion to define any ordinary term, such as “man” (Tractatus logicæ, Pt. I, chap. xxvi).
