Every plausible policy must be followed by the question 'And then what?'

The optimum population is, then, less than the maximum.

Fundamentalists are panicked by the apparent disintegration of the family, the disappearance of certainty and the decay of morality. Fear leads them to ask, if we cannot trust the Bible, what can we trust?

The population problem has no technical solution; it requires a fundamental extension in morality.

But as population became denser, the natural chemical and biological recycling processes became overloaded, calling for a redefinition of property rights.

In a finite world this means that the per capita share of the world's goods must steadily decrease.

Freedom in a commons brings ruin to all.
