Philosophy is the discipline concerned with questions of how one should live (ethics); what sorts of things exist and what are their essential natures (metaphysics); what counts as genuine knowledge (epistemology); and what are the correct principles of reasoning (logic). The word is of Greek origin: φιλοσοφία (philosophía), meaning love of wisdom.
Definition of Philosophy
No single definition of philosophy is uncontroversial. The field has historically expanded and changed depending upon what kinds of questions were interesting or relevant in a given era.
Different philosophers have had varied ideas about the nature of reason.
The Thinker- A philosophical Structure
The term analytic philosophy roughly designates a group of philosophical methods that stress clarity of meaning above all other criteria. The philosophy developed as a critique of Hegel and his followers in particular, and of speculative philosophy in general.
Some schools in the group include 20th-century realism, logical.
atomism, logical positivism, and
ordinary language. The motivation is to have philosophical studies
go beyond personal opinion and begin to have the cogency of
mathematical proofs. Applied philosophy
The thoughts a society thinks have profound repercussions on what it does. The applied study of philosophy yields applications such as those in ethics – applied ethics in particular – and political philosophy.
Other important applications can be found in epistemology, which aid in understanding the requisites for knowledge, sound evidence, and justified belief (important in law, economics, decision theory, and a number of other disciplines).
