I've recently come across many intelligent individuals in the field of metaphysics. Their intellectual prowess impressed me; since their field of expertise informs all other fields, they demonstrated an amazing knack for understanding concepts and critically analyzing them. Yet, they use terms like 'relational concept,' 'quantitatively/qualitatively,' 'principally as opposed to pragmatically,' 'formal/informal,' etc.,. I also noticed that they generally develop their argument from the most basic categories, necessarily involving the 5 predicables (they are able to classify anything into genus/species). It's been months since I have been exposed to this kind of an intellectual environment; it has allowed me to think more in depth about about anything (text, science, argument, speech, etc.,) that I come across.
Basically, I want to keep up with them, so I want to know of the basic terms that will help me navigate this field. Thanks!
