I did not then notice this. Only occasionally⁠—not by reason but by instinct⁠—I revolted against this superstition so common in our day, by which people hide from themselves their lack of understanding of life.⁠ ⁠… So, for instance, during my stay in Paris, the sight of an execution revealed to me the instability of my superstitious belief in progress. When I saw the head part from the body and how they thumped separately into the box, I understood, not with my mind but with my whole being, that no theory of the reasonableness of our present progress could justify this deed; and that though everybody from the creation of the world had held it to be necessary, on whatever theory, I knew it to be unnecessary and bad; and therefore the arbiter of what is good and evil is not what people say and do, nor is it progress, but it is my heart and I. Another instance of a realization that the superstitious belief in progress is insufficient as a guide to life, was my brother’s death. Wise, good, serious, he fell ill while still a young man, suffered for more than a year, and died painfully, not understanding why he had lived and still less why he had to die. No theories could give me, or him, any reply to these questions during his slow and painful dying.
