We seem to have forgotten that the expression "a liberal education" originally meant among the Romans one worthy of free men; while the learning of trades and professions by which to get your livelihood merely, was considered worthy of slaves only. But taking a hint from the word, I would go a step further and say, that it is not the man of wealth and leisure simply, though devoted to art, or science, or literature, who, in a true sense, is liberally educated, but only the earnest and free man.
Henry David ThoreauWe love to hear some men speak, though we hear not what they say; the very air they breathe is rich and perfumed, and the sound of their voices falls on the ear like the rustling of leaves or the crackling of the fire. They stand many deep.
Henry David ThoreauYou will pardon some obscurities, for there are more secrets in my trade than in most men's, and yet not voluntarily kept, but inseparable from its very nature. I would gladly tell all that I know about it, and never paint "No Admittance" on my gate.
