The twinkling of an eye. That is the most wonderful expression. I've thought from time to time it was the best thing in life, that little incandescence you see in people when the charm of a thing strikes them, or the humor of it. 'The light of the eyes rejoiceth the heart.' That's a fact.

Oddly enough, my favorite genre is not fiction. I'm attracted by primary sources that are relevant to historical questions of interest to me, by famous old books on philosophy or theology that I want to see with my own eyes, by essays on contemporary science, by the literatures of antiquity.

The classic theology of my tradition comes from the French Renaissance. [William] Shakespeare was born in 1564, the year [John] Calvin died, and that theology was very influential in England in his lifetime. I think Shakespeare was attentive to questions raised by it, about human nature, history, reality itself. I find the two literatures to be mutually illuminating.

Memory is the sense of loss, and loss pulls us after it.

A man can know his father, or his son, and there might still be nothing between them but loyalty and love and mutual incomprehension.

It's not a man's working hours that is important, it is how he spends his leisure time.
