I shall now go on to explain in detail how completely unsatisfactory are the answers that are at present given it; how it is evaded by some and begged by others; and how those that are most plausible are really made worthless, by a subtle but profound defect.
These answers divide themselves into two classes, which, though invariably confused by those that give them, are in reality quite distinct and separable.

Professor Huxley, one of the most vigorous of our positive thinkers, shall help us to understand these.

He is going to tell us, let us remember, about the '_highest good_'-- the happiness, in other words, that we have just been discussing--the secret of our life's worth, and the test of all our conduct.

This happiness he divides into two kinds.[8] He says that there are two things that we may mean when we speak about it.

We may mean the happiness of a society of men, or we may mean the happiness of the members of that society.
