Quote of the Day: René Descartes

So if we seriously wish to propose rules for ourselves which will help us scale the heights of human knowledge, we must include, as one of our primary rules, that we should take care not to waste our time by neglecting easy tasks and occupying ourselves only with difficult matters. That is just what many people do: they ingeniously construct the most subtle conjectures and plausible arguments on difficult questions, but after all their efforts they come to realize, too late, that rather than acquiring any knowledge, they have merely increased the number of their doubts.

– René  Descartes,  The Philosophical Writings of Descartes
