and NOT some Schopenhauerian "genius of the species"!) Whichever groups of sensations within a soul awaken most readily, begin to speak, and give the word of command—these decide as to the general order of rank of its values, and determine ultimately its list of desirable things. A man's estimates of value betray something of the STRUCTURE of his soul, and wherein it sees its conditions of life, its intrinsic needs. Supposing now that necessity has from all time drawn together only such men as could express similar requirements and similar experiences by similar symbols, it results on the whole that the easy COMMUNICABILITY of need, which implies ultimately the undergoing only of average and COMMON experiences, must have been the most potent of all the forces which have hitherto operated upon mankind.
