Philosophy is the study of general and fundamental problems, such as those connected with
reality,
existence,
knowledge,
values,
reason,
mind, and
language.
[1][2]
Philosophy is distinguished from other ways of addressing such problems
by its critical, generally systematic approach and its reliance on
rational argument.
[3]
In more casual speech, by extension, "philosophy" can refer to "the
most basic beliefs, concepts, and attitudes of an individual or group".
