338 PART V. WORKING STAGE. 



by applying Conclusion 28, the query: "How far is each sense 

 and any group of senses assisted, not assisted, never assisted, 

 impeded, etc., by each sense and any group of senses, and by 

 movement, impulse, feeling, mood, habit, memory, imagination, 

 ratiocination, will, etc.?" Similarly, noticing the term bio- 

 mechanics, I extend to all the divisions of physics ; then, back- 

 ward, apply all biological divisions to physics; then, forward 

 again, from physics and biology to specio-psychics ; and, lastly, 

 all the sub-divisions of the above to all the sub-divisions of the 

 above, in the most methodical manner practicable. (See Con- 

 clusion 33, Scheme of Classification.) In generalising in this 

 manner, it should not be excessively difficult to reach an ap- 

 preciable number of useful and sometimes invaluable minor 

 and major statements. Yet it ought to be borne in mind that 

 such methodical generalising, if it is to proceed far, is only of 

 real utility after we have ascertained a prodigious variety of 

 uniformities. Else we are pumping mud, and are sacrificing 

 considerably more time in futile verification than we should 

 have spent in independent observation. 



Once more. When examining a series of conclusions at which 

 we have arrived, we endeavour to note in what profitable order 

 they may be arranged. The suggestion is, perhaps, that a for- 

 ward, lateral, or some other order is most appropriate. As we 

 inspect the conclusions in the order which apparently most 

 nearly fits them, we observe, however, applying Conclusion 27, 

 that various links are missing. We, accordingly, complete the 

 chain by detecting and inserting the missing links. Mendelyeff s 

 periodic law is a prominent exemplification of this method, and 

 a kindred one would be the proper classification of the sciences. 

 (See Conclusion 33.) However, the problem here discussed is 

 not only one of completing a system. It may be a question of 

 proportion. There may be a too large or too small, a too 

 much or too little, a too this or too that. We then prune 

 or graft until there is a practically balanced or complete re- 

 sult before us. The multitude of existing classifications may 

 be utilised as auxiliaries, as well as the special classifications 

 which have presented themselves during the enquiry. Finally, 

 when several items have been collected, we endeavour not 

 only to arrange them in a certain order, but to connect them, 

 and, if possible, to marshal them as parts of a single organised 

 totality. 



Or examine the problem of the elaboration of a rule of life. 

 Noting in the preliminary investigation that sundry fundamental 

 psychic qualities are comprised in the provisional rule, I strive 

 to complete these. Theoretically this means that we should act 

 with our whole mental nature, our whole mental nature being 

 defined in conformity with the text-books of psychology as 

 constituted of: the intelligence (interpreted as mainly memory, 

 imagination, reasoning, and judgment); the feelings (consisting,
