from the 1911 Encyclopedia Britannica, which recently became available online.
A special use of the verb "to train," in the sense of to educate, to instruct, to bring into fit and proper condition, mental, moral or physical, is developed, as in "educate" (Lat. educare, literally, to draw out), from the sense of drawing or bringing out the good qualities aimed at in a course of instruction; a specific use is that of training for a race or other form of athletics, i.e. getting into fit physical condition.
The self is not something ready-made, but something in continuous formation through choice of action.
John Dewey, from The Quotations Page.
