Philosphy

There seems to be 5 different main divitions of philosophy. And there are futher divisions, but i wont mention them. Read wikipedia about philosophy branches here for further information about these branches.

• Metaphysics: In Western philosophy this field has become the study of the fundamental nature of all reality - what is it, why is it, and how are we to understand it. Some only regard metaphysics as the study of "higher" reality or the "invisible" nature behind everything, but that isn't actually true. It is, instead, the study of all of reality, visible and invisible. Metaphysics covers the kinds of things most people probably think of if asked what philosophy covers e.g. those 'big questions', such as, is there God, why are we here, what is the ultimate nature of the universe, and so on. Another important area of metaphysics is the nature of substance, that is, what is the universe really made of. Metaphysics has often come under attack for being too abstract to actually have any worth, particularly famously by A.J. Ayer. Classic works include Aristotle's Metaphysics, Spinoza's Ethics (which unsurprisingly also is a classic work on Ethics), and almost anything written by Leibniz.
• Epistemology: The philosophy of knowledge. Concerned with such questions as, is knowledge of anything really possible, is our knowledge certain, how do we get our knowledge, what things can we have knowledge about, what exactly is knowledge, etc. Epistemological studies usually focus upon our means for acquiring knowledge; thus modern epistemology generally involves a debate between rationalism and empiricism, or the question of whether knowledge can be acquired a priori or a posteriori. Classic works include Descartes' Meditations, Locke's An Essay Concerning Human Understanding, Hume's Treatise on Human Nature, and Kant's Critique of Pure Reason. Almost all the major philosophers have written on this subject, though it is less popular nowadays.
• Ethics: This is probably the most self-explanatory of all the branches. Concerned with such things as what is good/evil, is there such a thing as objective morals or are they created by us, or some other being, how we should live our lives, and so on. Classic works include Plato's Republic, Aristotle's Nichomachean Ethics, Kant's Groundwork for the Metaphysics of Morals, Nietzsche's Beyond Good and Evil.
• Politics: Closely related to ethics, this is a study of government and nations, particularly how they came about, what makes good governments, what obligations citizens have towards their government, and so on. Classic works include Plato's Republic, Hobbes' Leviathan, Locke's Two Treatises, and J.S. Mill's On Liberty.
• Aesthetics: The philosophy of art. Concerned with questions like why do we find certain things beautiful, what makes things great art, so on. The word comes from the Greek aisthetikos, "of sense perception." Aesthetics has traditionally been part of other philosophical fields like epistemology or ethics but it started to come into its own and become a more independent field under Immanuel Kant. Classic works include Aristotle's Rhetoric and Poetics, Schopenhauer and Hegel's lectures, Kant's Critique of Judgement. Plato had a famously dim view of this branch.

Philosophy is the study of general problems concerning matters such as existence, knowledge, truth, beauty, justice, validity, mind, and language. Philosophy is distinguished from other ways of addressing these questions (such as mysticism) by its critical, generally systematic approach and its reliance on reasoned argument. The word philosophy is of ancient Greek origin meaning "love of wisdom."
