Quotable Screwtape

I've been rereading C. S. Lewis' The Screwtape Letters in preparation for a book club.  For those of you unfamiliar with the book, the demon Screwtape writes a series of letters to the novice Wormwood, coaching him in  the use of sinful temptations to undermine their "patients" - mankind.  The following quote is a sample of the wisdom about the "road" to hell, albeit from the perspective of the evil Screwtape:

"You will say that these are very small sins; and doubtless, like all young tempters, you are anxious to be able to report spectacular wickedness.  But do remember, the only thing that matters is the extent to which you separate the man from the Enemy [God].  It does not matter how small the sins are, provided that their cumulative effect is to edge the man away from the Light and out into the Nothing.  Murder is no better than cards if cards can do the trick.  Indeed, the safest road to Hell is the gradual one -- the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts.  Your affectionate uncle, Screwtape"
