What wisdom can there be to choose, what continence to forbear without the knowledge of evil? He that can apprehend and consider vice with all her baits and seeming pleasures, and yet abstain, and yet distinguish, and yet prefer that which is truly better, he is the true wayfaring Christian.
I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary, but slinks out of the race where that immortal garland is to be run for, not without dust and heat.
That virtue therefore which is but a youngling in the contemplation of evil, and knows not the utmost that vice promises to her followers, and rejects it, is but a blank virtue, not a pure; her whiteness is but an excremental whiteness.
If all the world Should in a pet of temp'rance, feed on pulse, Drink the clear stream, and nothing wear but frieze, Th' All-giver would be unthank'd, would be unprais'd.
O impotence of mind, in body strong! But what is strength without a double share Of wisdom, vast, unwieldy, burdensome, Proudly secure, yet liable to fall By weakest subtleties, not made to rule, But to subserve where wisdom bears command.
Thus with the year Seasons return; but not to me returns Day, or the sweet approach of even or morn, Or sight of vernal bloom or summer's rose, Or flocks, or herds, or human face divine; But cloud instead, and ever-during dark Surrounds me; from the cheerful ways of men Cut off, and for the book of knowledge fair Presented with a universal blank Of Nature's works, to me expung'd and raz'd, And wisdom at one entrance quite shut out.
