The Republic · ¶377

When the training in music and gymnastic is completed, there follows the first stage of active and public life. But soon education is to begin again from a new point of view. In the interval between the Fourth and Seventh Books we have discussed the nature of knowledge, and have thence been led to form a higher conception of what was required of us. For true knowledge, according to Plato, is of abstractions, and has to do, not with particulars or individuals, but with universals only; not with the beauties of poetry, but with the ideas of philosophy. And the great aim of education is the cultivation of the habit of abstraction. This is to be acquired through the study of the mathematical sciences. They alone are capable of giving ideas of relation, and of arousing the dormant energies of thought.
