The pessimist Arthur Schopenhauer says this about life
..it is then well said that life should be, from one end to the other, only a lesson; to which, however, any one might reply: for this very reason I wish I had been left in the peace of the all sufficient nothing, where I would have had no need of lessons or anything else.
He continues, I guess, as a response to those who claim life is a gift
For human existence, far from being a gift, has entirely the character of a debt that has been contracted. The calling in of this debt appears in the form of the pressing wants, tormenting desires, and endless misery established through this existence. As a rule, the whole lifetime is devoted to the paying off of this debt; but this only meets the interest. The payment of the capital takes place through death. And when was this debt contracted? At the begetting.
I am tempted to agree with him.
