For a long time we both thought that this world had no ultimate meaning and that consequently we were cheated. I still think so in a way. [...]

You never believed in the meaning of this world, and you therefore deduced the idea that everything was equivalent and that good and evil could be defined according to one's wishes. You supposed that in the absence of any human or divine code the only values were those of the animal world--in other words, violence and cunning. Hence you concluded that man was negligible and that his soul could be killed, that in the maddest of histories the only pursuit for the individual was the adventure of power and his only morality, the realism of conquests. And, to tell the truth, I, believing I thought as you did, saw no valid argument to answer you except a fierce love of justice which, after all, seemed to me as unreasonable as the most sudden passion.

Where lay the difference? Simply that you readily accepted despair and I never yielded to it. Simply that you saw the injustice of our condition to the point of being willing to add to it, whereas it seemed to me that man must exalt justice in order to fight against eternal injustice, create happiness in order to protest against a universe of unhappiness. Because you turned your despair into toxication, because you freed yourself from it by making a principle of it, you were willing to destroy man's works and to fight him in order to add to his basic misery. Meanwhile, refusing to accept that despair and that tortured world, I merely wanted men to rediscover their solidarity in order to wage war against their revolting fate.
