Excellence of mind itself, rightly conceived, is expertise in beauty; creativity is wise love.

Psychologically time is seldom homogenous but rather is as full of shapes as space.

Truth is rhythmical: if it implies stasis, it is platitude. Truth is syncopated: if it supplies all the terms, there is one term too many. Truth is barbed: if it comforts, it lies. Truth is an armed dancer.

The fundamental motive of true teaching is the love that seeks and studies and performs.

If the estimated age of the cosmos were shortened to seventy-two years, a human life would take about ten seconds. But look at time the other way. Each day is a minor eternity of over 86,000 seconds. During each second, the number of distinct molecular functions going on within the human body is comparable to the number of seconds in the estimated age of the cosmos. A few seconds are long enough for a revolutionary idea, a startling communication, a baby's conception, a wounding insult, a sudden death. Depending on how we think of them, our lives can be infinitely long or infinitely short.

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

Creativity is dangerous. We cannot open ourselves to new insights without endangering the security of our prior assumptions. We cannot propose new ideas without risking disapproval and rejection.
