Famous quotes containing the words internal and/or workings:
“I believe that there was a great age, a great epoch when man did not make war: previous to 2000 B.C. Then the self had not really become aware of itself, it had not separated itself off, the spirit was not yet born, so there was no internal conflict, and hence no permanent external conflict.”
—D.H. (David Herbert)
“So much of truth, only under an ancient obsolete vesture, but the spirit of it still true, do I find in the Paganism of old nations. Nature is still divine, the revelation of the workings of God; the Hero is still worshipable: this, under poor cramped incipient forms, is what all Pagan religions have struggled, as they could, to set forth.”
—Thomas Carlyle (1795–1881)
