There is, and always has been, some question about the scope and content of philosophy. What is it, and what does it talk about? Not to speak of the often-asked question, what is it good for? And of course, anybody who spends time playing at philosophy will develop some sort of notion about the answers to those questions. Not being an authority, the final answer cannot be given in this column, but clearly it would be appropriate to say what my intentions are.
The most basic answer is probably to be found in the origins of the study: The greeks began a discussion of philosophy over 2500 years ago, in an attempt to escape the eternal dogmatic squabbles of prophets, teachers, and masters–the traditional way people developed their beliefs. Their idea was simple: try to figure out the answers to our questions using logic and reason, rather than looking to revelation, divination, and unsupported claims. It was really that simple. They didn’t say there were no gods, and they didn’t refuse to listen to Homer’s poetry, but they set that all over in one corner called tradition and opened up the questions anew, to be answered a different way.
Now, of course, in the centuries that have passed, numerous specialized disciplines have emerged to address specific classes of questions. Many of these are sciences of some sort. Others, like astrology, have fallen into folklore and superstition, and are no longer given serious credence. Philosophy remains as the odd man out, without a clearly defined question, yet clearly distinct from all these other knowledge disciplines.
There is an apocryphal story about one philosopher who, when asked what philosophy was about, pointed to the shelves of books behind his desk and said, “It’s what these books are about.” That’s a good start, but it leaves wanting the question of how do you tell when a new book belongs on his shelf?
There is another approach, preferred by pragmatists, that answers the question this way: Philosophy is what philosophers do. Not very good either, is it, because it begs the question of who are the philosophers, and while we might go by one’s academic title, it isn’t clear that only academics with the title “Philosopher” qualify for the post. In fact, to be a bit of a scamp, we might wonder if some of the people professionally considered to be philosophers aren’t something else, when instead of advancing the cause of philosophy, they advance the cachet of some other discipline, like physics, or psychology, or evolution science.
But let’s not get into that now.
When I do philosophy, there are two main issues. One is the sorting of social categories, and by this I mean sorting out the sciences, deciding what they entail, and describing what they do. This sort of classification began with Aristotle’s work, but Aristotle cannot be the last word on the subject since new ideas, new methods, new fields are always emerging. And clearly it isn’t exclusively the job of the mathematician to say what mathematics is, or of the poet to delimit the field of poetry. There are cross-disciplinary issues, and ultimately, it’s a social question, since we are social beings who do these things. At such a high level of disquisition, many people are qualified to speak, not least the people who intend to be in the field, but certainly philosophy, acting as the General Science, has to assist in the effort. This is not one of my major themes, but I see it as a basic function of philosophy.
The second is the questioning of Man’s relationship to the Universe. Philosophy is a very homocentric concern. We’re not interested, as the physicist is, in the color of electrons for its own sake. We want to know why we should care, and we want to take some concern for how this knowledge, and its pursuit, improves or impairs the welfare of mankind. Philosophy is ethics, among other things, and it seeks to distinguish the Good from the Evil, and surely this is not something the dispassionate, objective, fact-based sciences can do with any clear confidence.
Philosophy is interested in the nature of society, both what it is doing, and what it should be doing. How we organize ourselves and how we pursue our lives is a choice, and philosophy is the field where we analyze the choices and prioritize them. Philosophy is concerned with social architecture, and we can see some of its products in the social contract theory of J. J. Rousseau, or the natural ethics of John Locke, people who laid the foundations for our modern political state.
Philosophy has always included the study of how we think, that is, what methods can we use, and what are their strengths? So the study of logic is part of mathematics, but it’s also a part of philosophy. The philosophical approach is different from the mathematical approach, for, in mathematics, we create a formal method, such as boolean logic, and define its primitive notions, and set it out on the table as a tool ready to use; but there is no justification for it, no arguments that say why you should use it, or whether it’s any good. It exists as a construct, shorn of the philosophy that justifies its very existence. Philosophy provides that justification, and suggests what kind of criteria might be applied for judging methods.
Philosophy is ultimately concerned with the nature of Man himself. And if, someday, we meet intelligent aliens, it will be concerned with their nature too, not in the biological sense, but as Beings. We want to know who we are, why we’re here, what we should do, and what our purpose is. There is no final answer to these questions because the way we measure the answers is always subject to change and growth, but the building of the answers, for today, for ourselves, this is what we have to do as philosophers.
It has often been said that Science answers questions like How, When, Where, and we no longer respect Why. Why calls for purposes, motives, and teleology, and so it garners no respect. If a Why question is answered at all, it’s answered by saying how. The sky is blue, because molecules of air refract different frequencies of light in different degrees, etc etc. The sky is blue because various phyusical mechanisms cause this. But this isn’t why the sky is blue. The sky is blue because it looks blue to us, and the explanation for this is shrouded deep in questions confronting both neuroscience and philosophy today. Some people don’t even believe in qualia. “Why is the sky blue” is a question without end.
So when I do philosophy, I”m really trying to understand my nature, and my relationship to others– other people, other things, and the universe as a whole. When science studies the observer, it becomes confused because science is empirical; it has to trust the observer to do its work, yet in making the study, it undermines the observer as an authority. Philosophy doesn’t have to be empirical. We can study the observer. And we must.
