“Do you not see how necessary a world of pains and troubles is to school an intelligence and make it a soul?”

“I am in that temper that if I were under water I would scarcely kick to come to the top.”

“The only means of strengthening one's intellect is to make up one's mind about nothing, to let the mind be a thoroughfare for all thoughts.”

“Open wide the mind's cage-door, She'll dart forth, and cloudward soar.”
