Lucifer

We call him at once the Angel of Light and the Angel of Darkness: is this because we instinctively feel that no one can know much till he has sinned much—or because we feel that extremes meet, or how?

The Oracle in Erewhon

The answer given by the oracle was originally written concerning any vice—say drunkenness, but it applies to many another—and I wrote not “sins” but “knows”: [26]

He who knows aught
Knows more than he ought;
But he who knows nought
Has much to be taught.
