Letter 50 — On Our Blindness and Its Cure (§4)

“Why do we deceive ourselves? The evil that afflicts us is not external, it is within us, situated in our very vitals; for that reason we attain soundness with all the more difficulty, because we do not know that we are diseased. Suppose that we have begun the cure; when shall we throw off all these diseases, with all their virulence? At present, we do not even consult the physician, whose work would be easier if he were called in when the complaint was in its early stages. The tender and the inexperienced minds would follow his advice if he pointed out the right way.”
