Note 242 — Chapter IX · ROMANTIC MELANCHOLY
Reading edition
This is the thought of Keats’s Ode to Melancholy:
Ay, in the very temple of Delight Veil’d Melancholy has her sovran shrine, Though seen of none save him whose strenuous tongue Can burst Joy’s grape against his palate fine.
Cf. Chateaubriand: Essai sur les Révolutions, Pt. II, ch. LVIII: “Ces jouissances sont trop poignantes: telle est notre faiblesse, que les plaisirs exquis deviennent des douleurs,” etc.
