the answer is that of Nature. For since the concurrence of the three kinds of education is necessary to their completeness, the kind which is entirely independent of our control must necessarily regulate us in determining the other two." Then he defines Nature to mean the capacities and dispositions which are inborn, "as they exist prior to the modification due to constraining habits and the influence of the opinion of others."
The wording of Rousseau will repay careful study. It contains as fundamental truths as have been uttered about education in conjunction with a curious twist. It would be impossible to say better what is said in the first sentences. The three factors of educative development are (a) the native structure of our bodily organs and their functional activities; (b) the uses to which the activities of these organs are put under the influence of other persons; (c) their direct interaction with the environment. This statement certainly covers the ground. His other two propositions are equally sound; namely, (a) that only when the three factors of education are consonant and coöperative does adequate development of the individual occur, and (b) that the native activities of the organs, being original, are basic in conceiving consonance.
But it requires but little reading between the lines, supplemented by other statements of Rousseau, to perceive that instead of regarding these three things as factors which must work together to some extent in order that any one of them may proceed educatively, he regards them as separate and independent operations. Especially does he believe that there is an independent and, as he says, 'spontaneous' development of the native organs and faculties. He thinks that this development can go on irrespective of the use to which they are put. And it is to this separate development that education coming from social contact is to be subordinated. Now there is an immense difference between a use of native activi-
