In thirty-odd years’ study of the arcane field of Philosophy, I have not learned very much; which perhaps means that I am doing it right.
Here is one thing I have definitely learned:
In the field of Philosophy, there are two kinds of people: Philosophers and Academic Philosophers. All the actual philosophies are created by the first group, but it is the second group that gets tenure.
Philosophers think very hard about the meaning of life, the nature of knowledge, and things like that, and write about it for the public.
Academic Philosophers, by tradition, are angry old men with beards and elbow patches who write incomprehensible gobbledygook at each other because they just like arguing that much.
In these enlightened times, however, Academic Philosophy has risen above its ignoble past and taken on a whole new look. For nowadays, most of the Academic Philosophers are clean-shaven.
