one in other respects. And our theory is only asserting that the connection which it believes to hold between rightness and the production of a maximum of pleasure is, in this respect, similar to the connection asserted to hold between the number two and the number four, when we say that twice two are four. It asserts that, if any being whatever, in any circumstances whatever, had to choose between two actions, one of which would produce more pleasure than the other, it always would be his duty to choose the former rather than the latter: that this is absolutely unconditionally true. This assertion obviously goes very much further, both than the assertion which it made in its first part, to the effect that the producing a maximum of pleasure is a sign of rightness in the case of all voluntary actions, that ever have been or will be actual or possible, and also than the assertion, that in the Universe, as it is actually constituted, actions are right, when they are right, because they produce a maximum of pleasure. But bold as the assertion may seem, it is, at all events, not impossible that we should know it to be true.
