In the circle of philosophy, we have two kinds of philosophy.
The first kind is a pure philosophy. And the second
kind is an applied one. The pure philosophy is the philosophy
which explores philosophical ideas within the area of
philosophy only. Pure philosophy consists of three major
branches: metaphysics, epistemology, and ethics (esthetics
is included in ethics as both of them study a thing called in
philosophy as ‘value.’ Metaphysics studies what beyond
human perception. Epistemology studies what to be
counted as properties of knowledge. So, these three
branches have their different subjects.)
