At all events, teachings of that description have an infallible effect upon natures of a peculiar stamp.
If you should wish to close the lips of a logician calling himself a philosopher, who dares to argue that in this life grief overbalances pleasure, ask him whether he would accept a life entirely without sorrow and happiness.

Be certain that he will not answer you, or he will shuffle, because, if he says no, he proves that he likes life such as it is, and if he likes it, he must find it agreeable, which is an utter impossibility, if life is painful; should he, on the contrary, answer in the affirmative, he would declare himself a fool, for it would be as much as to say that he can conceive pleasure arising from indifference, which is absurd nonsense.
Suffering is inherent in human nature; but we never suffer without entertaining the hope of recovery, or, at least, very seldom without such hope, and hope itself is a pleasure.

If it happens sometimes that man suffers without any expectation of a cure, he necessarily finds pleasure in the complete certainty of the end of his life; for the worst, in all cases, must be either a sleep arising from extreme dejection, during which we have the consolation of happy dreams or the loss of all sensitiveness.

But when we are happy, our happiness is never disturbed by the thought that it will be followed by grief.

Therefore pleasure, during its active period, is always complete, without alloy; grief is always soothed by hope.
