“I poured my soul into the dust by loving a man who was soon to die, as if he would live forever.”
― Augustine of Hippo, The Confessions of Saint Augustine: Books I-X

“For with regard to nature, it is indeed experience which supplies us with the rule and is the source of truth; with regard to moral laws, however, experience is, alas!, but the mother of illusion; and it is altogether reprehensible either to derive or to try to limit the laws of what we ought to do from what is done.”
― Immanuel Kant, Critique of Pure Reason

“Human nature," I continued, "has its limitations. It can bear joy and suffering, and pain to a certain degree, but perishes when this point is passed. Here there can therefore be no question of whether a man is strong or weak, but of whether he can endure his suffering, be it moral or physical. And I find it just as astonishing to say that a man who takes his own life is a coward, as it would be improper to call a man a coward who dies of a pernicious fever.”
― Johann Wolfgang von Goethe, The Sorrows of Young Werther and Selected Writings

“I want to talk about everything with at least one person as I talk about things with myself.”
― Fyodor Dostoyevsky
