For, indeed, this is the great horror, solitude, when the soul can no longer bathe in the ever-changing mind, laugh as its sunlit ripples lap its skin, but, shut up in the castle of a few thoughts, paces its narrow prison, wearing down the stone of time, feeding on its own excrement. There is no star in the blackness of that night, no foam upon the stagnant and putrid sea. Even the glittering health that the desert brings to the body, is like a spear in the soul's throat. The passionate ache to act, to think: this eats into the soul like a cancer. It is the scorpion striking itself in its agony, save that no poison can add to the tortue of the circling fire; no superflux of anguish relieve it by annihilation. But against these paroxisms is an eightfold sedative. The ravings of madness are lost in soundless space; the struggles of the drowning man are not heeded by the sea.
