The truth is, when all is said and done, one does not teach a subject, one teaches a student how to learn it. - Jacques Barzun

Philosophers no longer write for the intelligent, only for their fellow professionals. The few thousand academic philosophers in the world do not stint themselves: they maintain more than seventy learned journals. But in the handful that cover more than one subdivision of philosophy, any given philosopher can hardly follow more than one or two articles in each issue. This hermetic condition is attributed to "technical problems" in the subject. Since William James, Russell, and Whitehead, philosophy, like history, has been confiscated by scholarship and locked away from the contamination of general use.

The French call mot juste the word that exactly fits. Why is this word so hard to find? The reasons are many. First, we don't always know what we mean and are too lazy too find out.
