“Friendship is one mind in two bodies.”
“What is love? two souls and one flesh; friendship? two bodies and one soul.”
“One will in two minds, one heart in two bodies, and two bodies in one flesh.”
“To be capable of steady friendship or lasting love, are the two greatest proofs, not only of goodness of heart, but of strength of mind.”
“Friendship: A ship big enough for two in fair weather, but only one in foul.”
“We see in essence not with two eyes but with three: with the two eyes of the body and with the eye of the mind that is behind them.”
