“Scepticism is as much the result of knowledge, as knowledge is of scepticism. To be content with what we at present know, is, for the most part, to shut our ears against conviction; since, from the very gradual character of our education, we must continually forget, and emancipate ourselves from, knowledge previously acquired; we must set aside old notions and embrace fresh ones; and, as we learn, we must be daily unlearning something which it has cost us no small labour and anxiety to acquire.”
― Homer, The Iliad

“Until we have begun to go without them, we fail to realize how unnecessary many things are. We've been using them not because we needed them but because we had them.”
― Lucius Annaeus Seneca, Letters from a Stoic

“Liberate the minds of men and ultimately you will liberate the bodies of men.”
― Marcus Garvey

― Marcus Garvey
