Seeing neither hook nor line

You shall see neither hook nor line, much less the subtle angler himself, while he is offering you his bait. And his bait shall be so fitted to your temper and disposition, that he will be sure to find advantages within you, and make your own principles and inclinations betray you; and whenever he ruineth you, he will make you the instruments of ruin to others.

--Richard Baxter (12 November 1615 – 8 December 1691, commenting upon the nature of temptation and our adversary).
