“Constant association with the wicked fosters bad habits.
Better the hopes of the educated than the wealth of the ignorant.
Unity creates friendship.
People should care more for the soul than for the body. For the soul’s perfection corrects the body’s defects, while bodily strength without reason does nothing to improve the soul.”

(Some sayings of Democritus, from the book Democritus in His Fragments and Testimonies of Antiquity. Democritus was one of the greatest ancient Greek philosophers, a founder of atomistic materialism and a pupil of Leucippus, 460–370 BC.)
