Here’s a thought that could—and likely should—be further developed, but I won’t do so: the thought being that life is much too interesting and varied to become overly specialized.
I’m not saying that specialization is all bad, or that I can even name the line where it becomes myopic, insular and just plain ridiculous. I’m just saying that most of us (in the Western world) crossed this line some time ago, and that I refuse to let philosophy, politics, photography, theology, culture, technology, or any other -ology or -ism put me in the ingeniously small boxes (they’re getting smaller all the time!) that the modern world has made for us.
Life is much too broad, much too varied and fertile for that kind of thing.
