For just as there is as much or more sensation involved in the visual perception of an object that I hold close to my eyes and carefully examine as in the perception of an entire countryside that I look at haphazardly and without much attention, with the result that the clarity of the sensation I have of the object near my eyes makes up for the scope of my confused sensation of the many things I see at random in the countryside, so the perception the mind has of a single object is sometimes so lively and distinct that it contains as much or even more thought than the perception of the relations between several objects.
