552 SUMMARY AND CONCLUSION. 



which we set out, and with which our re-survey must com- 

 mence. For this integrated form of knowledge is the form 

 which, apart from the doctrine of Evolution, we decided to 

 be the highest form. 



When we inquired what constitutes Philosophy when 

 we compared men's various conceptions of Philosophy, so 

 that, eliminating the elements in which they differed we 

 might see in what they agreed; we found in them all, the 

 tacit implication that Philosophy is completely unified 

 knowledge. Apart from each particular scheme of unified 

 knowledge, and apart from the proposed methods by which 

 unification is. to be effected, we traced in every case the be- 

 lief that unification is possible, and that the end of Philoso- 

 phy is the achievement of it. 



Accepting this conclusion, we went on to consider the 

 data with which Philosophy must set out. Fundamental 

 propositions, or propositions not deducible from deeped ones, 

 can be established only by showing the complete congruity 

 of all the results reached through the assumption of them; 

 and, premising that they were assumed till so established, 

 we took as our data, those organized components of our in- 

 telligence without which there cannot go on the mental 

 processes implied by philosophizing. 



From the specification of these we passed to certain 

 primary truths " The Indestructibility of Matter," " The 

 Continuity of Motion," and " The Persistence of Force; " 

 of which the last is ultimate and the others derivative. 

 Having previously seen that our experiences of Matter and 

 Motion are resolvable into experiences of Force ; we further 

 saw the truths that Matter and Motion are unchangeable in 

 quantity, to be implications of the truth that Force is un- 

 changeable in quantity. This we discovered is the truth 

 by derivation from which all other truths are to be proved. 



The first of the truths which presented itself to be so 

 proved, was " The Persistence of the Relations among 

 Forces." This, which is ordinarily called Uniformity of
