Of all the truly seismic shifts transforming daily life today -- deeper than our financial fissures, wider even than our most obvious political and cultural divides -- one of the most important is also among the least remarked. That is the chasm in attitude that separates almost all of us living in the West today from almost all of our ancestors, over two things without which human beings cannot exist: food and sex.

The question before us today is not whether the two appetites are closely connected. About that much, philosophers and other commentators have been agreed for a very long time. As far back as Aristotle, observers have made the same point reiterated in 1749 in Henry Fielding's famous scene in Tom Jones: The desires for sex and for food are joined at the root. The fact that Fielding's scene would go on to inspire an equally iconic movie segment over 200 years later, in the Tom Jones film from 1963, just clinches the point.
What happens when, for the first time in history, adult human beings are free to have all the sex and food they want?
