I recently enjoyed this presentation by Sean Carroll that touches on definitional and philosophical issues with entropy. The talk made me feel less stupid for not feeling entirely comfortable with how entropy was explained to me before. Turns out there are a few different ways to define and quantify entropy that are used in different contexts and they each have some unresolved philosophical issues.

I wonder how many concepts that are so complicated for our brain to formalize or even process.
Another surprising thing is that physicists have not yet succeeded in reducing the ordinary notion of cause and effect to fundamental physics. Carroll has also worked on this issue.
I would recommend reading some Carlo Rovelli, it sounds like something you might like.
