408 THE WORLD AS WILL. bk. iv.
and put us out of humour; but experience also teaches that if a great misfortune, at the mere thought of which we shuddered, actually befalls us, as soon as we have overcome the first pain of it, our disposition remains for the most part unchanged; and, conversely, that after the attainment of some happiness we have long desired, we do not feel ourselves on the whole and permanently very much better off and agreeably situated than before. Only the moment at which these changes occur affects us with unusual strength, as deep sorrow or exulting joy, out both soon pass away, for they are based upon illusion. For they do not spring from the immediately present pleasure or pain, but only from the opening up of a new future which is anticipated in them.

It would follow, from the hypothesis advanced, that a large part of the feeling of suffering and of well-being would be subjective and determined a priori, as is the case with knowing: and we may add the following remarks as evidence in favour of it. Human cheerfulness or dejection are manifestly not determined by external circumstances, such as wealth and position, for we see at least as many glad faces among the poor as among the rich. Further, the motives which induce suicide are so very different, that we can assign no motive that is so great as to bring it about, even with great probability, in every character, and few that would be so small that the like of them had never caused it.
