Truth and Utility
Mill, seeking to prove that all our sciences, even the mathematical, have an empiric origin, brings forward the following consideration. If on every occasion that we had to take twice two things, some deity slipped one extra thing into our hands, we should be convinced that twice two is not four but five. And perhaps Mill is right: perhaps we should not divine what was the matter. We are much more concerned to discover what is practically necessary and directly useful to us than to search for truth. If a deity with each four things slipped a fifth into our hands, we should accept the additional thing and consider it natural, intelligible, necessary, impossible to be otherwise. The very uniformity in the sequence of phenomena observed by the empirical philosophers was also slipped into our hands. By whom? When? Who dares to ask? Once the law is established no one is interested in anything any more. Now we can foretell the future, now we can use the thing slipped into our hands, and the rest—cometh of the evil one.
