I've been looking through my old course webpages to see what I want to salvage for Houyhnhnm Land, and came across my old doggeral mnemonic ('dogmonic' as I called it) for the thought of Hume's Treatise 1.4.7. And I thought you might like to read it for yourself:
The Shipwreck of David Hume
(Oh, and you can compare it 1.4.7 itself. Scroll down to section VII.)
