No psychological message is so open to question as that which tells us that we have nothing left to do or to give.

True intimacy is a human constant. People of all types find it equally hard to achieve, equally precious to hold. Age, education, social status, make little difference here; even genius does not presuppose the talent to reveal one's self completely and completely absorb one's self in another personality. Intimacy is to love what concentration is to work: a simultaneous drawing together to attention and release of energy.

True teachers not only impart knowledge and method but awaken the love of learning by their own reflected love.
