Refutation

The best refutation of the imaginary Malthusian laws of "land depletion" is the practice of Soviet collective farming.

Near-synonyms: rebuttal (see note), counterargument, counterassertion, counterclaim, denial

Apply these tests to his arguments and you will render your task of refutation easier. But in your refutation, be sure you refute. Don’t think for a minute that either heat or violence or sarcasm is a good answer.

The conclusion to which we shall be led by a full consideration of these facts will be that the effective refutation of such errors will frequently require further intellectual advance, and often advance on points which are very abstract and may seem very remote from the practical issues.
