Hast thou reason? I have. Why then dost not thou use it? For if this does its own work, what else dost thou wish?
Marcus AureliusThings themselves cannot touch the soul, not in the least degree, nor have they admission to the soul nor can they turn or move the soul: it turns and moves itself alone and whatever judgment it may think proper to make, such it makes by remaking for itself the things that present themselves to it
Marcus Aurelius
