"It should not be believed that there are limits to the horror that the human mind is capable of accepting.  On the contrary, everything seems to indicate that as the darkness grows deeper, that depth begins to grow exponentially - and while we refuse to admit it, experience tells us that when the nightmare turns black enough, the horror begins to grow, and  one accidental evil breeds another, often deliberate evil, until finally darkness swallows everything.  The most terrible question is, exactly how much of the horror„
