In the states of Maxilua and Callet, in Further Spain, as well as in Pitane in Asia Minor, there are bricks which, when finished and dried, will float on being thrown into water. The reason why they can float seems to be that the clay of which they are made is like pumice-stone. So it is light, and also it does not, after being hardened by exposure to the air, take up or absorb liquid. ...They have therefore great advantages; for they are not heavy to use in building and, once made, they are not spoiled by bad weather.

The Great War through which we have passed differed from all ancient wars in the immense power of the combatants and their fearful agencies of destruction, and from all modern wars in the utter ruthlessness with which it was fought. ... Europe and large parts of Asia and Africa became one vast battlefield on which after years of struggle not armies but nations broke and ran. When all was over, Torture and Cannibalism were the only two expedients that the civilized, scientific, Christian States had been able to deny themselves: and these were of doubtful utility.

"When I was a freshman, I fooled around with shooting free throws this way: For some reason, I thought you had to stay within the top half of that free-throw circle, so I would step back to just inside the top of the circle, take off from behind the line and dunk. They outlawed that, but I wouldn't have done it in a game, anyway. I was a good free throw shooter in college." Actually he was a 62% free throw shooter, which is poor except in comparison to his 51% as a pro.

Once efficiency is universally accepted as a rule, it becomes an inner compulsion and weighs like a sense of sin, simply because no one can ever be efficient enough, just as no one can ever be virtuous enough. And this new sense of sin only contributes further to the enervation of leisure, for the rich as well as the poor.The difficulty of carrying on a leisure-oriented tradition of culture in a work-oriented society is enough in itself to keep the present crisis in our culture unresolved.

It is so hard for an evolutionary biologist to write about extinction caused by human stupidity. [...] Let me then float an unconventional plea, the inverse of the usual argument. [...] The extinction of Partula is unfair to Partula. That is the conventional argument, and I do not challenge its primacy. But we need a humanistic ecology as well, both for the practical reason that people will always touch people more than snails do or can, and for the moral reason that humans are legitimately the measure of all ethical questions-for these are our issues, not nature's.

Let's be clear: all professions look bad in the movies. And there's a good reason for this. Movies don't portray career paths, they conscript interesting lifestyles to serve a plot. So lawyers are all unscrupulous and doctors are all uncaring. Psychiatrists are all crazy, and politicians are all corrupt. All cops are psychopaths, and all businessmen are crooks. Even moviemakers come off badly: directors are megalomaniacs, actors are spoiled brats. Since all occupations are portrayed negatively, why expect scientists to be treated differently?
