Quote:
To judge the appearances we receive of things, we should need a judicatory instrument; to verify this instrument, we should need a demonstration; to rectify this demonstration, we should need an instrument: so here we are arguing in a circle.
Seeing 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 all eternity.
