At issue is not only knowledge of the world but our survival as individuals and as a species. All the basic technologies ever invented by humans to feed and protect themselves depend on a relentless commitment to hard-nosed empiricism: you cannot assume that your arrowheads will pierce the hide of a bison or that your raft will float just because the omens are propitious and you have been given supernatural reassurance that they will. You have to be sure.

Upscale people are fixated with food simply because they are now able to eat so much of it without getting fat, and the reason they don't get fat is that they maintain a profligate level of calorie expenditure.

Given the cultural barriers to intersex conversation, the amazing thing is that we would even expect women and men to have anything to say to each other for more than ten minutes at a stretch. The barriers are ancient -- perhaps rooted, as some paleontologist may soon discover, in the contrast between the occasional guttural utterances exchanged in male hunting bands and the extended discussions characteristic of female food-gathering groups.

The secret of the truly successful, I believe, is that they learned very early in life how not to be busy. They saw through that adage, repeated to me so often in childhood, that anything worth doing is worth doing well. The truth is, many things are worth doing only in the most slovenly, halfhearted fashion possible, and many other things are not worth doing at all.

we are reaching the point, if we have not passed it already, where the largest public housing program in America will be our penitentiary system.
