Macbeth's self-justifications were feeble - and his conscience devoured him. Yes, even Iago was a little lamb too. The imagination and the spiritual strength of Shakespeare's evildoers stopped short at a dozen corpses. Because they had no ideology.
Aleksandr SolzhenitsynA work of art contains its verification in itself: artificial, strained concepts do not withstand the test of being turned into images; they fall to pieces, turn out to be sickly and pale, convince no one. Works which draw on truth and present it to us in live and concentrated form grip us, compellingly involve us, and no one ever, not even ages hence, will come forth to refute them.
Aleksandr SolzhenitsynMany of you have already found out, and others will find out in the course of their lives, that truth eludes us if we do not concentrate our attention totally on it's pursuit. But even while it eludes us, the illusion of knowing it still lingers and leads to many misunderstandings. Also, truth seldom is pleasant; it is almost invariably bitter.
