Oportet ingenii aciem ad res minimas et maxime faciles totam convertere, atque in illis diutius immorari, donec assuescamus veritatem distincte et perspicue intueri.
“It is necessary to turn the mind the whole of the edge of the easy to very little, and most of all, and to spend time with them for a long time, until we accustom ourselves to look at the truth distinctly and clearly.
We should totally focus the vision of the natural intelligence on the smallest and easiest thing, and we should dwell on them for a long time, so long, until we have become accustomed to intuiting the truth distinctly and perspicuously. “
– Rene Descartes on perspicacity : a penetrating discernment – a clarity of vision or intellect which provides a deep understanding and insight
