Re: [math-fun] how do you structure causality?

In freshman Humanities, we had to read Hume's 1. *An Enquiry Concerning Human Understanding*<http://www.infidels.org/library/historical/david_hume/human_understanding.html> **wherein he concluded causality was essentially illusory. Or so I gathered. In his gedanken mechanics, the terminology was so muddled and in conflict with modern terminology that I boggled. --rwg
