MALTHUSIAN, adj. Pertaining to Malthus and his doctrines. Malthus
believed in artificially limiting population, but found that it could
not be done by talking. One of the most practical exponents of the
Malthusian idea was Herod of Judea, though all the famous soldiers
have been of the same way of thinking.
-- Ambrose Bierce, "The Devil's Dictionary"
