Abstract

Ought we, for instance, to begin by discussing each separate species — man, lion, ox, and the like — taking each kind in hand independently of the rest, or ought we rather to deal first with the attributes which they have in common in virtue of some common element of their nature, and proceed from this as a basis for the consideration of them separately?
