Unless we love and are loved, each of us is alone, each of us is deeply lonely.

Love consists in giving without getting in return; in giving what is not owed, what is not due the other. That's why true love is never based, as associations for utility or pleasure are, on a fair exchange.

Education is the sum total of one's experience, and the purpose of higher education is to widen our experiences beyond the circumscribed existence or our own daily lives.

Television, radio, and all the sources of amusement and information that surround us in our daily lives are also artificial props. They can give us the impression that our minds are active, because we are required to react to stimuli from the outside. But the power of those external stimuli to keep us going is limited. They are like drugs. We grow used to them, and we continuously need more and more of them. Eventually, they have little or no effect. Then, if we lack resources within ourselves, we cease to grow intellectually, morally, and spiritually. And we we cease to grow, we begin to die.

The person who says he knows what he thinks but cannot express it usually does not know what he thinks.

Ask others about themselves, at the same time, be on guard not to talk too much about yourself.

Theories of love are found in the works of scientists, philosophers, and theologians.
