One critic complained that my argument was ‘philosophical’, as though that was sufficient condemnation. Philosophical or not, the fact is that neither he nor anybody else has found any flaw in what I said. And ‘in principle’ arguments such as mine, far from being irrelevant to the real world, can be more powerful than arguments based on particular factual research. My reasoning, if it is correct, tells us something important about life everywhere in the universe. Laboratory and field research can (...) tell us only about life as we have sampled it here.

In a recent Inquiry article Louis Pascal argues that the problem of massive starvation in the modern world is the result of a genetically-based human propensity to produce as many offspring as possible, regardless of ecological conditions. In this paper biological and anthropological objections to Pascal's thesis are discussed as well as the conclusions he draws from it. It is suggested that natural selection has produced humans who are flexible in their reproductive behavior in order to cope with rapidly changing (...) environments. The implications of both arguments for the population movement and the attempt to eliminate starvation are discussed. (shrink)
