This difficulty, however, may be waived. We may even waive the fact that a theory which set out to be ultra-empirical is now enmeshed in the need for making empirical facts meet dialectical requirements. Another difficulty is too insuperable to be waived. In any case the quantity of elementary existences which constitutes the criterion of measurement is dependent upon the very judgment which is assumed to be regulated by it. The standard of valuation is the units which will _result_ from an act; they are future consequences. Now the character of the agent judging is one of the conditions of the production of these consequences. A callous person not only will not foresee certain consequences, and will not be able to give them proper weight, but he does not afford the same condition of their occurrence which is constituted by a sensitive man. It is quite possible to employ judgment so as to produce acts which will increase this organic callousness. The analytic conception of the moral criterion provides--logically--for deliberate blunting of susceptibilities. If the matter at issue is simply one of number of units of pleasure over pain, arrange matters so that certain pains will not, as matter of fact, be felt. While this result may be achieved by manipulation of extra-organic conditions, it may also be effected by rendering the organism insensitive. Persistence in a course which in the short run yields uneasiness and sympathetic pangs, will in the long run eliminate these pains and leave a net pleasure balance.
