Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence.

One must state it plainly. Religion comes from the period of human pre-history where nobody - not even the mighty Democritus who concluded that all matter was made from atoms - had the smallest idea what was going on.

Nothing could make me forget what the Reagan years had actually been like.

In order to be a part of the totalitarian mind-set, it is not necessary to wear a uniform or carry a club or a whip. It is only necessary to wish for your own subjection, and to delight in the subjection of others.

The Bible may, indeed does, contain a warrant for trafficking in humans, for ethnic cleansing, for slavery, for bride-price, and for indiscriminate massacre, but we are not bound by any of it because it was put together by crude, uncultured human mammals.

In one way, traveling has narrowed my mind. What I have discovered is something very ordinary and unexciting, which is that humans are the same everywhere and that the degree of variation between members of our species is very slight. This is of course an encouraging finding; it helps arm you against news programs back home that show seething or abject masses of either fanatical or torpid people. In another way it is a depressing finding; the sorts of things that make people quarrel and make them stupid are the same everywhere.

When I abandoned the smoking habit of more than three decades I was given a supposedly helpful pill called Wellbutrin. But as soon as I discovered that this was the brand name for an antidepressant, I tossed the bottle away. There may be successful methods for overcoming the blues but for me they cannot include a capsule that says: 'Fool yourself into happiness, while pretending not to do so.' I should actually want my mind to be strong enough to circumvent such a trick.
