Allama Iqbal: Don’t Separate Rational Thought from Concrete Experience!

Allama Iqbal tells us stuff about how to think.

If you don't already know this, Iqbal is an influential 1900s Islamic philosopher of the Subcontinent (i.e., India and Pakistan, but before the separation of the two).

He has one of the better philosophy mustaches, and he's the only great philosopher I can name who has an airport named after him, but there are better reasons to be familiar with his thought.
