Abstract
The operation of the human intellect is twofold, however; first, simple perception, 'simple apprehension,' the 'simple gaze of indivisibles' and second, composition and division or judgment. In considering the principles of human knowledge it is therefore necessary to distinguish simple principles from complex principles or axioms. It is evident, however, that being is absolutely first of all complex as well as incomplex principles. "That which first falls under apprehension is being, the understanding of which is included in all things whatsoever man apprehends. Therefore, the first indemonstrable principle is the same cannot be affirmed and denied at the same time, which is based on the constitutive intelligibility of being and non-being: and on this principle all others are based."
