June 26, 2021 Off By Felso

Philosophy, with its wide range of influence and interest, is one of the oldest pursuits of human existence, which has been the source of all fields of science. The issues and problems addressed in philosophy depend on the questions asked and the answers given to them.

From sports to art, from ethics to politics, from language to science, all kinds of issues that concern people and their actions are the direct field of interest and way of dealing of philosophy. In this context, philosophy is divided into different sub-disciplines within the framework of the subjects it covers.

In this title, we will try to explain these philosophical disciplines one by one and briefly. Because each sub-discipline is already available as a separate heading in their broadest form on

We can say that there are three main subjects of philosophy that have remained unchanged since the First Age: Existence, knowledge, value.

“What is being, which deals with being as a whole?” philosophy of being seeking the answer to the question;
“What is the source and value of the information?” philosophy of knowledge seeking the answer to the question;
Examining human life and basic virtues, “What is good?” philosophy of value seeking the answer to the question.

Apart from these, different subjects and sub-branches have emerged according to the ages, historical and social conditions. Subjects and sub-branches of philosophy can be listed as follows in relation to the questions asked:

What is the source of power? (political philosophy)
What is beautiful? (philosophy of art)
What is religion? (philosophy of religion)
What is science? (philosophy of science)
Is accurate information possible? (philosophy of knowledge)
Can anything be said to exist? (philosophy of being)
Are there universal moral rules? (moral philosophy)
Philosophy of knowledge (epistemology)

One of the subjects that philosophy deals with is knowledge. Science is also interested in this subject. But science does not investigate what knowledge is. Philosophy explores this. Philosophy also tries to find the relation of knowledge to what it is acquired, its relevance to what it is gained, and the measure of this conformity.

Ontology, which deals with tangible entities that can be seen and tangible, as well as abstract entities such as numbers, concepts, ideas, primarily deals with the problem of existence or not.

Moral philosophy (ethics)

It is a branch of philosophy that considers human actions as a special problem area, investigates the principles that govern them, and wants to find out what “ought to be” behaviors are as well as “what is happening”.
