According to Wikipedia,
Philosophy is the study of general problems concerning matters such as existence, knowledge, truth, beauty, law, justice, validity, mind, and language.
[1][2] Philosophy is distinguished from other ways of addressing these questions (such as
mysticism or
mythology) by its critical, generally systematic approach and its reliance on
reasoned argument.
[3] The word
philosophy is of
Ancient Greek origin:
φιλοσοφία (
philosophía), meaning "love of wisdom."
[4][5][6]
According to a printed philosophical dictionary, philosophy is love for the truth and in this sense probably first used in the socratic school; it goes on to mention that the word φιλοσοφοσ,
or philosopher,
was first used by Heraclit in the sense of one searching for the nature of things. (H. Schmidt, G. Schischkoff, Philosophisches Wörterbuch).
According to an on-line philosophical dictionary:
Literally, love of wisdom. Hence, careful thought about the fundamental nature of the world, the grounds for human knowledge, and the evaluation of human conduct. As an academic discipline, philosophy's chief branches include
logic,
metaphysics,
epistemology, and
ethics, and the appropriate aims and methods of each are the concern of
metaphilosophy. (

Apart from this, philosophy may also be (sub)divided into ancient, medieval and modern or Western, Christian, Islamic or Eastern philosophy.
Philosophy then,
being the oldest theoretical discipline to strive for knowledge and wisdom, may for some have a clear definition, while for others the definition itself is a philosophical problem to be answered. In addition, philosophy is not an empirical science, but a normative one; instead of relying on practical experiment it is founded on reasoning and mental experiment. As a consequence there will never be empirical evidence to support a certain philosophical vison or theory. (The conclusion that philosophy not be a science, however, ignores the fact that all science presuposes certain principles a priori.)
I think that may do by way of an introduction.
So, if anyone has a question relative to philosophy, I shall do my best to answer it, or, failing that, indicate where the answer might be found.
And if anyone feels the need to discuss issues of philosophical interest, feel free to do so here.
