Living Within Limits - Chapter 11

The Demostat

Negative feedback is essential to produce stability in a self-regulating system.  Consider elements in nature, such as body temperature, blood sugar level, cell salt level, or even animal population levels.

The Malthusian Demostat is the theory of what regulates human populations.  Hardin argues, like the Demostat, that 'true respect for life must include respect for the functions and necessity of death'

Demostat
Overpopulation -> Misery/Vice -> Less Fertility/More Death -> Equilibrium
Underpopulation -> Surplus -> More Fertility/Less Death -> Equilibrium

Individual thinking vs community thinking...

These two philosophies have conflicting values.  In individual thinking, the value of one person is infinite, and cannot possibly be sacrificed.  Any action which causes the suffering to accrue to just one person is unjustifiable.  In community thinking, there are certain actions that, though unpleasant for individuals, can be a 'blessing' to the whole.

Community-oriented thinking was more pervasive during prior times, than today.  Though we now have mega-cities, western society (the drivers of progress) are shifting individuals further and further away from communities.  Today, the 'greatest honor is accorded to speakers who focus on individual interests to the exclusion of community interests.'
