If you want to understand what it means to be afraid, what fear as experienced by human beings is, then your focus must shift. No longer will you be satisfied with mechanical, physiological, neurological accounts. For this inquiry will require you to observe closely what human beings feel, sing, think, write and say to one another.

Modern science is a vast attempt to homogenize the universe. Aristotelian science, by contrast, remains faithful to our lived experience, and thus conceives of the world as essentially heterogeneous; composed of different kinds of beings.

The great virtue, I think, of studying Aristotle - and, more importantly, taking him seriously as a possible teacher - is that he presents an alternative view of both science and the world.

Even before Plato, techne was conceived as knowledge of a determinate field that could be mastered by "the expert". Such a person becomes an authority to whom laypersons should, in their dealings with that field, defer. Techne typically results in a useful result.

Postmodernism - and is that term used much any more? - is simply a reiteration of the sophistic or the rhetorical worldview.

We live in a technocratic culture. We worship at the altar of technology. Our lives are increasingly shaped by the machinations of the techies. It is vital, therefore, for all of us to think hard about the role the technical plays in our lives.

The earth is, of course, not the geometric center of the universe. But it is certainly the center of our lives.
