Quotations
Many well formed and well fed bodies over-indulge in sensuality, take little or no exercise, and remain sickly throughout life ; many well formed minds, over-indulge in mere gossip, frivolous conversations, and reading novels, take no serious thought or study, and remain common-place through life; or worse than common-place, being more or less intensely perverted in proportion to original endowments of mental capacity.
