Jargon Alert!

Jargon, I’m learning, is a fundamental element of philosophy. Here are some especially confusing terms from today’s 3-hour Philosophy of Time seminar:
-relational construct
-mode of being/comes into being
-physical reality

…and my favorite:
-precondition for the possibility of experience

(I'm thinking about doing a jargon of the week post, so email me if you find any good ones!)
