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

Because it is a radical act of freedom, creative achievement is a heroic process that requires, in all its permutations, specific strengths of character.

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.

We are wistful about the golden days of the past and dream of a distant future unclouded by necessity. But I suspect that if our inner souls were asked what in life they really missed, the answer would be primal danger and stress.

That morning I experienced vividly, if almost subliminally, the reality of change itself: how it fools our sentinels and undermines our defenses, how careful we are to look for it in the wrong places, how it does not reveal itself until it is beyond redress, how vainly we search for it around us and find too late that is has occurred within us.

Happiness may well consist primarily of an attitude toward time.

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.
