before we are able to frame the propositions needed to express that answer. Or, while writing an essay, how often does one feel, so to speak, that a certain truth stands to be stated, although it is a truth which we cannot immediately put into words. We know, in a general way, that a truth is _there_, but we cannot supply the vehicle which is to bring it _here_; and it is not until we have tried many devices, each of which involve long trains of sequent propositions, that we begin to find the satisfaction of rendering explicit in language what was previously implicit in thought. Again, in playing a game of chess we require to take cognizance of many and complex relations, actual and contingent; so that to play the game as it deserves to be played, we must make a heavy demand on our powers of abstract thinking. Yet in doing this we do not require to preach a silent monologue as to all that we might do, and all that may be done by our opponent. Lastly, to give only one other illustration, in some forms of aphasia the patient has lost every trace of verbal memory, and yet his faculties of thought for all the practical purposes of life are not materially impaired. On the whole, therefore, I conclude that, although language is a needful condition to the _original construction_ of conceptional thought, when once the building has been completed, the scaffolding may be withdrawn, and yet leave the edifice as stable as before. In this way familiar concepts become, as it were, degraded into recepts, but recepts of a degree of complexity and organization which would not have been possible but for their conceptional parentage. With Geiger we may say, “So ist denn überall die Sprache primar, der Begriff entsteht durch das Wort.”[56] Yet this does not hinder that with Friedrich Müller we should add, “Sprechen ist nicht Denken, sondern es ist nur Ausdruck des Denkens.”[57] * * * * *
