The common notions that we find in credit around us and infused into our souls by our fathers' seed, these seem to be the universal and natural ones. Whence it comes to pass that what is off the hinges of custom, people believe to be off the hinges of reason.
Michel de MontaigneSeeing that the Senses cannot decide our dispute, being themselves full of uncertainty, we must have recourse to Reason; there is no reason but must be built upon another reason: so here we are retreating backwards to infinity.

Michel de Montaigne
