exercitātiō

Doctrina denotes learning as a particular species of intellectual cultivation, whereas eruditio the learned result, as the crown of intellectual cultivation. Doctrina evinces a superiority in particular branches of knowledge, and stands as a co-ordinate notion with exercitatio, which is distinguished from it by involving a superiority in the ready use of learning, and can therefore, even as a mere theory, be of more evident service in practice than that which is indirectly important; eruditio stands in still closer relation to practice, and involves the co-operation of the different branches of knowledge and different studies to the ennobling of the human race; it denotes genuine zeal for the welfare of mankind in an intellectual, as humanitas does in a moral, point of view. (v. 268.)
