The Discourse on Method

We must concentrate our minds I totally on the most insignificant and easiest of matters. In my translation he distinguishes two principal faculties of mine. Perspicacity viewing single objects distinctly and sagacity, skillful deduction of certain facts by others. But why did you just preface that with no Mark? You said that we had been talking about how this is accessible to everybody and anybody can do it. Well no because you have to hone your first precacity to actually see these distinct objects as clearly distinct. And you have to learn how to focus your attention in order for these supposedly universal inborn things to be seen clearly distinctly.
