there is a hard ceiling to food production, though Malthus (in ignorance of future technologies) greatly underestimated it.
We have not reached it, yet.
doesn't mean we won't. If/When we do, Malthus' nighmare scenario will come to pass.
Indeed. The great insight that Malthus had was that populations either check themselves, or the environment does it for them. For this we are apparently supposed to revile him, along with Darwin, and if the original poster's second link is to be believed, along with Edmund Burke. I'm not sure what we're to make of this when that same page says that Marxists rejected Malthus - apparently, here on the New Free Republic, Darwin and Edmund Burke are bad, because they were influenced by Malthus, and Marx is good because he rejected Malthus. And this is somehow "conservative". What a mess.
Where and when this fact has been established?
