The Philosophy of Evolution. 57 



We have seen that the logical process begins with the general 

 and ends with the individual; its material expression must 

 therefore begin with the lowest orders and end with the high- 

 est. But the individual cannot be immediately derived from 

 the general without the intervention of intermediate generali- 

 zations. No more in the concrete expression of this deduc- 

 tion can we pass from the lowest types to the highest without 

 the intervention of an intermediate series. These intermedi- 

 ate terms are not capable of independent interpretation ; they 

 find their full explanation only in the extremes of the series — 

 God and Man. 



If, then, in the intellectual process from the abstract and 

 universal towards the concrete and individual, we find a con- 

 stant evolution of idea, each advance being an addition to the 

 previous conception, each new term in the series embracing all 

 the attributes of the preceding, and differing only by addition ; 

 and if thought is possible only on this condition ; it necessari- 

 ly follows that the material representation of this thought 

 must present physical forms similarly related, so that, leav- 

 ing out of view the intellectual genesis of this relation, the 

 observer might conclude that these forms compose a series 

 evolved from a primordial cell in accordance with an organic 

 law. But such we find to be the universal law of intellectual 

 procedure : this apparent development or evolution must, 

 therefore, be the condition of the communication of such 

 intellectual process, and the physical terms are brought into 

 this relation by the fact that they symbolize the logical pro- 

 cess. If the material symbols of thought were unrelated 

 physically, the thoughts thus expressed would also be unrela- 

 ted and independent. But such a supposition renders Science 

 impossible, for its one aim is to find the same in the different. 

 If there be no same, there can be no science : if there be no 

 different, there can be no science. Thought proceeds by add- 

 ing the different to the same in an endless series, and this addi- 

 tion of the different to the same expressed in concrete forms is
