“The first degree of folly is to conceit one's self wise; the second to profess it; the third to despise counsel.”

The Architecture of Theories (1891)
Context: The origin of things, considered not as leading to anything, but in itself, contains the idea of First, the end of things that of Second, the process mediating between them that of Third. A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one. The idea of the Many, because variety is arbitrariness and arbitrariness is repudiation of any Secondness, has for its principal component the conception of First. In psychology Feeling is First, Sense of reaction Second, General conception Third, or mediation. In biology, the idea of arbitrary sporting is First, heredity is Second, the process whereby the accidental characters become fixed is Third. Chance is First, Law is Second, the tendency to take habits is Third. Mind is First, Matter is Second, Evolution is Third.

Dieu se manifeste à nous au premier degré à travers la vie de l’univers, et au deuxième degré à travers la pensée de l’homme. La deuxième manifestation n’est pas moins sacrée que la première. La première s’appelle la Nature, la deuxième s’appelle l’Art.
