How to get started in philosophy
It is a platitude (at least among people who write introductions to philosophy)
that everybody has a philosophy, though they might not all realize it or be
able to defend it. But at the same time the word "philosophy" as it is used
by philosophers is nothing like what is meant by people who say "Here's my
philosophy (of life, etc.): . . ." Such is the tension between pedagogy and
scholarship.
If you're already interested in studying philosophy, your reason might be to
improve the way you live or think somehow, or you simply wish to get
acquainted with one of the most ancient areas of human thought. On the other
hand, if you don't see what all the fuss is about, it might help to read the
motivation to philosophize, which explains what motivates many people to "do
philosophy," and get an introduction to philosophical method, which is
important to understanding how philosophers think. It might also help to
acquaint yourself with some considerations about just what philosophy is.
Those who are new to the subject of philosophy are advised to study logic,
metaphysics, philosophy of mind, philosophy of language, epistemology,
philosophy of science, ethics, and political philosophy as these are -
arguably - the central disciplines.
Applied philosophy
Philosophy has applications. The most obvious applications are those in ethics
,applied ethics in particular--and in political philosophy. The political
philosophies of John Locke, Jean-Jacques Rousseau, Karl Marx, John Stuart Mill
, and John Rawls have shaped and been used to justify governments and their
actions. Philosophy of education deserves special mention, as well;
progressive education as championed by John Dewey has had a profound impact
on educational practices in the United States in the twentieth century.
Other important, but less immediate applications can be found in epistemology,
which might help one to regulate one's notions of what knowledge, evidence,
and justified belief are. Philosophy of science discusses the underpinnings
of the scientific method, among other topics sometimes useful to scientists.
Aesthetics can help to interpret discussions of art. Even ontology, surely
the most abstract and least practical-seeming branch of philosophy, has had
important consequences for logic and computer science. In general, the various
"philosophies of," such as philosophy of law, can provide workers in their
respective fields with a deeper understanding of the theoretical or conceptual
underpinnings of their fields.
Moreover, recently, there has been developing a burgeoning profession devoted
to applying philosophy to the problems of ordinary life: philosophical
counseling.
Philosophy contrasted with other disciplines
Natural Science
Originally the term "philosophy" was applied to all intellectual endeavour.
Aristotle studied what would now be called biology, meterology, physics,
and cosmology, alongside his metaphysics and ethics. Even in the eighteenth
century physics and chemistry were still classified as "natural philosophy",
that is, the philosophical study of nature. Today these latter subjects are
referred to as science.
Psychology, economics, sociology, and linguistics were once the domain of
philosophers insofar as they were studied at all, but now have only a weaker
connection with the field. In the late twentieth century cognitive science
and artificial intelligence could be seen as being forged in part out of
"philosophy of mind."
Philosophy is done a priori. It does not and cannot rely on experiment
. However, in some ways philosophy is close to science in its character and
method; Analytic philosophy urges that philosophers should emulate the
methods of natural science; Quine holds that philosophy just is a branch
of natural science, simply the most abstract one. This approach, common
nowadays, is called "philosophical naturalism"
Philosophers have always devoted some study to science and the
scientific method, and to logic, and this involves, indirectly, studying
the subject matters of those sciences. Whether philosophy also has its own,
distinct subject matter is a contentious point. Traditionally ethics,
aesthetics, and metaphysics have all been philosophical subjects, but many
philosophers have, especially in the twentieth century, rejected these as
futile questions (the Vienna Circle). Philosophy has also concerned itself
with explaining the foundations and character knowledge in general (of
science, or history), and in this case it would be a sort of "science of
science" but some now hold that this cannot consist in any more than
clarifying the arguments and claims of other sciences. This suggests that
philosophy might be the study of meaning and reasoning generally; but some
still would claim either that this is not a science, or that if it is,
it ought not to be pursued by philosophers.
All these views have something in common: whatever philosophy
essentially is or is concerned with, it tends on the whole to proceed more
"abstractly" than most (or most other) natural sciences. It does not depend
as much on experience and experiment, and does not contribute as directly
to technology. It clearly would be a mistake to identify philosophy with
any one natural science; whether it can be identified with science very
broadly construed is still an open question.
Philosophy of Science
This is an active discipline pursued by both trained philosophers and
scientists. Philosophers often refer to, and interpret, experimental work
of various kinds (as in philosophy of physics and philosophy of psychology).
But this is not surprising: such branches of philosophy aim at philosophical
understanding of experimental work. It is not the philosophers in their
capacity as philosophers, who perform the experiments and formulate the
scientific theories under study. Philosophy of science should not be
confused with science it studies any more than biology should be confused
with plants and animals.
Theology and Religious studies
Like philosophy, most religious studies, are not experimental. Parts of
theology, including questions about the existence and nature of gods,
clearly overlap with philosophy of religion. Aristotle considered theology
a branch of metaphysics, the central field of philosophy, and most
philosophers prior to the twentieth century have devoted significant effort
to theological questions. So the two are not unrelated. But other part of
religious studies, such as the comparison of different world religions, can
be easily distinguished from philosophy in just the way that any other
social science can be distinguished from philosophy. These are closer to
history and sociology, and involve specific observations of particular
phenomena, here particular religious practices.
Nowadays religion plays a very marginal role in philosophy. The
empiricist tradition in modern philosophy often held that religious
questions are beyond the scope of human knowledge, and many have claimed
that religious language is literally meaningless: there are not even
questions to be answered. Some philosophers have felt that these
difficulties in evidence were irrelevant, and have argued for, against,
or just about religious beliefs on moral or other grounds. Nonetheless,
in the main stream of twentieth century philosophy there are very few
philosophers who give serious consideration to religious questions.
Mathematics
Math uses very specific, rigorous methods of proof that philosophers
sometimes (only rarely) try to emulate. Most philosophy is written in
ordinary prose, and while it strives to be precise it does not usually
attain anything like mathematical clarity. As a result, mathematicians
hardly ever disagree about results, while philosophers of course do
disagree about their results, as well as their methods.
The Philosophy of mathematics is a branch of philosophy of science;
but in many ways mathematics has a special relationship to philosophy. This
is because the study of logic is a central branch of philosophy, and
mathematics is a paradigm example of logic. In the late nineteenth and
twentieth centuries logic made great advances, and mathematics has been
proven to be reducible to logic (at least, to first-order logic with some
set theory). The use of formal, mathematical logic in philosophy now
resembles the use of math in science, although it is not as frequent.
Some tentative generalizations about what philosophy is
So philosophy, it seems, is a discipline that draws on knowledge that the
average educated person has, and it does not make use of experimentation and
careful observation, though it may interpret philosophical aspects of
experiment and observation.
More positively, one might say that philosophy is a discipline that
examines the meaning and justification of certain of our most basic,
fundamental beliefs, according to a loose set of general methods. But what
we might mean by the words "basic, fundamental beliefs"?
A belief is fundamental if it concerns those aspects of the universe
which are most commonly found, which are found everywhere: the universal
aspects of things. Philosophy studies, for example, what existence itself
is. It also studies valuethe goodness of things--in general. Surely in human
life we find the relevance of value or goodness everywhere, not just moral
goodness, though that might be very important, but even more generally,
goodness in the sense of anything that is actually desirable, the sense,
for example, in which an apple, a painting, and a person can all be good.
(If indeed there is a single sense in which they are all called "good.")
Of course, physics and the other sciences study some very universal
aspects of things; but it does so experimentally. Philosophy studies those
aspects that can be studied without experimentation. Those are aspects of
things that are very general indeed; to take yet another example,
philosophers ask what physical objects as such are, as distinguished from
properties of objects and relations between objects, and perhaps also as
distinguished from minds or souls. Physicists proceed as though the notion
of a physical body is quite clear and straightforwardwhich perhaps in the end
it will found to be--but at any rate, physics assumes that, and then asks
questions about how all physical bodies behave, and then does experiments to
find out the answers.
