Full Idea
If one concept is 'better' than an earlier one, it is because it makes us aware of new variations and unknown resonances, it carries out unforeseen cuttings-out, it brings forth an Event that surveys (survole) us.
Gist of Idea
Concepts are superior because they make us more aware, and change our thinking
