ON LIFE AND ORGANISATION. 299 



consciousness, the ground of his proper intellect, and the 

 conditioning element of his moral faculty, and of his religious 

 belief. It is the possession of this pneuma, which distinguishes 

 man from the animal. Possessing, like the animal, a body 

 and a psyche, he may descend, if he will, to the level of the 

 brute. But he has also had it put in his power, in virtue of 

 his pneuma, to participate in the conditions of a higher sphere

 and that, except as part of such a system, organisation cannot

 itself. 



The human mind, although limited in its capacity and capable

 nevertheless, within its own sphere of capacity and of action, 

 formed and endowed in perfect harmony with that whole, regarding 

 which, it is permitted to inquire, and to obtain knowledge. 



All acquired knowledge, properly so called, must therefore be 

 in harmony with the whole ; and the entire mass of human know-

 tutes a part. Acquired knowledge is the result of inquiry by 

 individual minds, into subjects more or less numerous and distinct. 

 But, as all minds have the same general constitution, and are 

 regulated in the process of inquiry by the same laws of thought, 

 and as, moreover, they are all formed in harmony with that whole,
