AND OF SETTING IT IN MOTION. 83 



he could be demonstrated if only a sufficient intelligence 

 had determined to search for him in earnest. His wants 

 could be expressed if he desired to express them. The 

 hydraulic machinery he governed, and the taps he turned on 

 or off, had been designed and made for a purpose according 

 to pattern, and they had been arranged in a definite manner 

 according to principles well known. Their arrangement 

 could have been ascertained by any one who chose to take 

 the trouble to find it out, and clearly demonstrated to per- 

 sons who desired to learn about it. The whole might have 

 been taken up and relaid exactly as it was before ; but could 

 the apparatus of the word-machine be taken to pieces and 

 put together again, just like " hydraulic machinery " ? 

 Let Mr. Huxley answer. But as to the "we" and the 

 " spring" of the word-machine. Well, if these cannot now 

 be clearly demonstrated, we shall be assured that it is quite 

 certain they will be rendered very evident to highly in- 

 telligent posterity, by the pre-eminent intellectual philo- 

 sophers about to be. The reader of the present day may, 

 perhaps, without committing a very grave outrage, be asked 

 to consider the force of Mr. Huxley's " just as," and even 

 encouraged to ask himself whether the analogies implied 

 are real or fictitious the analogy between the incorporeal 

 " we," and the living, moving, working, acting " engineer," 

 the analogy between the "spring" of the " word- 

 machine " and the " tap " of the hydraulic apparatus, the 

 analogy between the " spoken words " and the streams of 

 water. 



Descartes himself suggests that, when the " ' rational 

 soul ' is lodged in the machine, it will have its principal 

 seat in the brain, and will take the place of the engineer."
