Johann Wolfgang von Goethe on Philosophical pessimism

“It is as if a curtain had been drawn from before my eyes, and, instead of prospects of eternal life, the abyss of an ever open grave yawned before me. Can we say of anything that it exists when all passes away, when time, with the speed of a storm, carries all things onward,—and our transitory existence, hurried along by the torrent, is either swallowed up by the waves or dashed against the rocks? There is not a moment but preys upon you,—and upon all around you, not a moment in which you do not yourself become a destroyer. The most innocent walk deprives of life thousands of poor insects: one step destroys the fabric of the industrious ant, and converts a little world into chaos. No: it is not the great and rare calamities of the world, the floods which sweep away whole villages, the earthquakes which swallow up our towns, that affect me. My heart is wasted by the thought of that destructive power which lies concealed in every part of universal nature. Nature has formed nothing that does not consume itself, and every object near it: so that, surrounded by earth and air, and all the active powers, I wander on my way with aching heart; and the universe is to me a fearful monster, for ever devouring its own offspring.”

“"Human nature," I continued, "has its limits. It is able to endure a certain degree of joy, sorrow, and pain, but becomes annihilated as soon as this measure is exceeded. The question, therefore, is, not whether a man is strong or weak, but whether he is able to endure the measure of his sufferings. The suffering may be moral or physical; and in my opinion it is just as absurd to call a man a coward who destroys himself, as to call a man a coward who dies of a malignant fever." "Paradox, all paradox!" exclaimed Albert. "Not so paradoxical as you imagine," I replied. "You allow that we designate a disease as mortal when nature is so severely attacked, and her strength so far exhausted, that she cannot possibly recover her former condition under any change that may take place. "Now, my good friend, apply this to the mind; observe a man in his natural, isolated condition; consider how ideas work, and how impressions fasten on him, till at length a violent passion seizes him, destroying all his powers of calm reflection, and utterly ruining him. "It is in vain that a man of sound mind and cool temper understands the condition of such a wretched being, in vain he counsels him. He can no more communicate his own wisdom to him than a healthy man can instil his strength into the invalid, by whose bedside he is seated."”
