“Thus, we have three principles for increasing adequacy of data: if you must work with a single object, look for imperfections that record historical descent; if several objects are available, try to render them as stages of a single historical process; if processes can be directly observed, sum up their effects through time. One may discuss these principles directly or recognize the “little problems” that Darwin used to exemplify them: orchids, coral reefs, and worms—the middle book, the first, and the last.”

Penser, c'est voir! me dit-il un jour emporté par une de nos objections sur le principe de notre organisation. Toute science humaine repose sur la déduction, qui est une vision lente par laquelle on descend de la cause à l'effet, par laquelle on remonte de l'effet à la cause; ou, dans une plus large expression, toute poésie comme toute oeuvre d'art procède d'une rapide vision des choses.
Honoré de Balzac, Louis Lambert http://fr.wikisource.org/wiki/Louis_Lambert (1832), translated by Clara Bell
