irradiation Quotes

You will see Coleridgeöhe who sits obscure In the exceeding lustre and the pure Intense irradiation of a mind, Which, through its own internal lighting blind, Flags wearily through darkness and despairö A cloud-encircled meteor of the air, A hooded eagle among blinking owlsö You will see Huntöone of those happy souls Which are the salt of the earth, and without whom This world would smell like what it isöa tomb.

—Shelley, Percy Bysshe
