“Textbook Philosophy” has a two-part meaning.
Textbook: School textbooks.
Philosophy: I tend to think a lot about life when I’m supposed to be learning (by reading through my textbooks.)
So, there you have it :] Simple.
It’s not Textbook Philosophy as in an actual class you can take on Philosophy, but that I tend to become very philosophic during school, and become more involved in my thoughts than the text layed in front of me.
Later, Tumblr’s :]
