Thomas Malthus：An Essay on the Principle of Population, Excerpt 94

If this be the case, there is at once an end of all human science. The whole train of reasonings from effects to causes will be destroyed. We may shut our eyes to the book of nature, as it will no longer be of any use to read it. The wildest and most improbable conjectures may be advanced with as much certainty as the most just and sublime theories, founded on careful and reiterated experiments. We may return again to the old mode of philosophising and make facts bend to systems, instead of establishing systems upon facts. The grand and consistent theory of Newton will be placed upon the same footing as the wild and eccentric hypotheses of Descartes. In short, if the laws of nature are thus fickle and inconstant, if it can be affirmed and be believed that they will change, when for ages and ages they have appeared immutable, the human mind will no longer have any incitements to inquiry, but must remain fixed in inactive torpor, or amuse itself only in bewildering dreams and extravagant fancies.
