Many of our examples suggest that clarity and excellence in thinking is very much like clarity and excellence in the display of data. When principles of design replicate principles of thought, the act of arranging information becomes an act of insight.

Edward Tufte, Visual Explanations

Painters in the grand style were not concerned with style – they drew with clarity and rigor. Style was born from their work, and just as thought does not think about the sound of its voice nor even the rhythm, but creates them through its act – so they did not … Style must arise naturally from one’s attention to an object and it disappears as the awareness of this attention decreases.

Paul Valéry

The separation of the sciences and the arts is merely a matter of convention and convenience. But in thinking and acting, man transcends these categories which are simply particular acts. Each one implicitly contains the other.
