Did you find Hume's writing approachable? I'm skeptic by nature and always wanted to read him, but nowadays I tend to read articles instead of diving into 18th-century books...

For "Enquiry Concerning Human Understanding", I found this edition with explanations of certain words/phrases by Jonathan Bennett very useful: https://www.earlymoderntexts.com/assets/pdfs/hume1748.pdf
