To discover the why of it

From the introduction to Robert Hughes’s book on modern art, The Shock of the New:

I am not a philosopher, but a journalist who has had the good luck never to be bored by his subject. “Je resous de m’informer du pourquoi,” Baudelaire wrote after seeing Tannhäuser in 1860, “et de transformer ma volupté en connaissance”: “I set out to discover the why of it, and to transform my pleasure into knowledge.” Pleasure is the root of all critical appreciation of art, and there is nothing like a long, steady project to make one discover (and with luck, convey) what it was in the siren voices of our century that caught me as a boy—when I first read Roger Shattuck’s translations of Apollinaire, hidden from the Jesuits in the wrapper of a Latin grammar—and has never let me go.

In the same vein see Barthes on jouissance, and Ortega y Gasset on amor intellectualis; in the opposite vein, the Wordsworthian trope of murdering to dissect.
