One of the frustrating things about the modern world is its focus on specialization. To be fair, this is also one of the strengths of many businesses and organizations in the U.S. The U.S. military, for example, provides a baseline of military training to all soldiers, but then specializes them with significant additional training in their chosen field. There are few businesses where employees are cross-trained on other jobs as a matter of course. I've been thinking about all of this in my search for a new job (unlike many people, however, I still have the old one so I can afford to be a little picky). Our university system operates especially like this, with very focused majors. It is even rare for people to study multiple fields at the graduate level of education. Probably, this has a lot to do with the time it takes for such studies to bear fruit so that you can get paid.
Some of the most notable philosophers in the Western world were so-called "Rennaisance Men". Aristotle studied logic, ethics, politics, biology, and was arguably the first zoologist. Descartes attempted to reason from first principles, through the sciences, and into philosophy. Hobbes began with science and worked through religion into politics. Why did our greatest minds seek to bring together many different areas of thought? Did they see connections that we cannot?
It seems that part of being human might relate to bringing together the diverse parts of the world in ways that make sense. From an individual's perspective, all thoughts, experiences, sensations, and emotions are jumbled together. Although we try to split out the various parts of the world, perhaps it is this internal mixture that is leaking through making us want to fit such varied ideas together.
Personally, I try to remain something of a generalist. I am interested in so many different fields that I find it challenging to constrain my inquiries to one or two. While I'm sure it's impossible to be in expert in more than one, I wonder whether any of them is truly split apart from the others. I think we've shown over the course of time that many "Sciences" are interrelated, and many of the "Arts" are as well. I think we see true genius in those who can seamlessly integrate the two. By directing ourselves toward this interdisciplinary thought we may learn more than we bargained for.
