Thomas Malthus：An Essay on the Principle of Population, Excerpt 125

The probable increase of the voluntary power of man over his animal frame comes next under Mr Godwin's consideration, and he concludes by saying, that the voluntary power of some men, in this respect, is found to extend to various articles in which other men are impotent. But this is reasoning against an almost universal rule from a few exceptions; and these exceptions seem to be rather tricks, than powers that may be exerted to any good purpose. I have never heard of any man who could regulate his pulse in a fever, and doubt much, if any of the persons here alluded to have made the smallest perceptible progress in the regular correction of the disorders of their frames and the consequent prolongation of their lives.
