We have said that the peculiar sorrow of the mind is the sorrow of not knowing or not understanding, which includes the sorrow of being powerless; for he who knows the supreme causes, being no longer paralysed by matter, becomes one with them and acts with them; and he who understands ends by approving, or else the universe would be a mistake, which is not possible, an infinite mistake being inconceivable. I do not believe that another sorrow of the sheer mind can be imagined. The only one sorrow which, at first thought, might seem admissible—and which, in any case, could be but ephemeral—would arise from the sight of the pain and misery remaining on the earth which we have left. But this sorrow, after all, would be but one aspect and an insignificant phase of the sorrow of being powerless and of not understanding. As for the latter, though it is not only beyond the domain of our intelligence, but even at an insuperable distance from our imagination, we may say that it would be intolerable only if it were without hope. But, for that, the universe would have to abandon any attempt to understand itself, or else admit within itself an object that remained for ever foreign to it. Either the mind will not perceive its limits and, consequently, will not suffer from them, or else it will overstep them as it perceives them; for how could the universe have parts eternally condemned to form no part of itself and of its knowledge? Hence we cannot understand that the torture of not understanding, supposing it to exist for a moment, should not end by absorption in the state of infinity, which, if it be not happiness as we comprehend it, could be naught but an indifference higher and purer than joy.
