When I say that human beings are just gene machine...

Intelligent life on a planet comes of age when it first works out the reason for its own existence.

I was confirmed at my prep school at the age of 13.

Design can never be an ultimate explanation for anything. It can only be a proximate explanation. A plane or a car is explained by a designer but that's because the designer himself, the engineer, is explained by natural selection.

Whatever you may look like, marry a man your own age - as your beauty fades, so will his eyesight.

A bad manner spoils everything, even reason and justice a good one supplies everything, gilds a No, sweetens a truth, and adds a touch of beauty to old age itself.

Our scientific age demands that we provide definitions, measurements, and statistics in order to be taken seriously. Yet most of the important things in life cannot be precisely defined or measured. Can we define or measure love, beauty, friendship, or decency, for example?

I'm very accepting with my age. It's like notches on your belt: experience, wisdom, and a different kind of beauty. There comes a day when you've become comfortable in your skin.

How incessant and great are the ills with which a prolonged old age is replete.

The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all. And that, of course, causes great confusion.

Every great architect is - necessarily - a great poet. He must be a great original interpreter of his time, his day, his age.

Once I planned to write a book of poems entirely about the things in my pocket. But I found it would be too long and the age of the great epics is past.
