"the impersonal, mindless—and therefore implacable—cruelty to which all men are subject. The universe with its violent natural forces was cruel in Artaud's eyes, and this cruelty, he felt, was the one single most important fact of which man must be aware. . . . Artaud's theater must be ecstatic. It must crush and hypnotize the onlooker's sense."
the alternative IMO is an "implacable cruelty" which is not expressed (felt) but created, not lived with - but a rebellion against those that do... it is not the shadow of traditional theatre, but artaud's shadow - and with it perhaps the last great expression of hope.
