I also believe - and hope - that politics and economics will cease to be as important in the future as they have been in the past; the time will come when most of our present controversies on these matters will seem as trivial, or as meaningless, as the theological debates in which the keenest minds of the Middle Ages dissipated their energies. Politics and economics are concerned with power and wealth, neither of which should be the primary, still less the exclusive, concern of full-grown men.

The person one loves never really exists, but is a projection focused through the lens of the mind onto whatever screen it fits with least distortion.

A wise man once said that all human activity is a form of play. And the highest form of play is the search for Truth, Beauty and Love. What more is needed? Should there be a ‘meaning’ as well, that will be a bonus? If we waste time looking for life’s meaning, we may have no time to live — or to play.

As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.

You can't have it both ways. You can't have both free will and a benevolent higher power who protects you from yourself.

There is hopeful symbolism in the fact that flags do not wave in a vacuum.
