What is the basic concept of philosophy

I’m not sure what you meant to ask. There are a lot of philosophy “basics,” including ideas, key arguments, and fields. As such is the case, the most accurate answer I could give you is a list of what I refer to as the pillars of philosophy. In other words, these are the main subjects / subsets of philosophy that people study.

1. Epistemology: What can we know, if anything? Why can we know anything? What is the basis for our knowing anything?

2. Existentialism: Why are we here? What does it mean to live a good life? Does life have meaning? How does one derive meaning without the presence of a god?

3. Logic: How does one craft a logical argument? What are the logical fallacies, both formal and informal? How does one assess whether an argument is logical? Broadly, the language of philosophical argumentation.

4. The Question of Free Will: Do we have free will? Is all action determined? Are free will and determinism compatible?

5. Philosophy of Mind & Philosophy of Body: Does the problem of dualism exist? How are the mind and the body connected, if at all?

6. Ethics: How does one behave morally or ethically? Is there even such a thing as morality? If morality does exist, does it have any foundation? Does morality require an absolute foundation? What, if any, is the so-called “best” ethical system to abide by? Can there be such a thing as coherent ethical pluralism?

To each of these, there are many more subfields, and there are also a couple of large fields that I have left out. But it seems to me that these are the most prevalent and relevant to the average human. So in a pragmatic sense, these may be considered as the most important.

So basically the concept of philisophy is the systematic study of ideas and issues, a reasoned pursuit of fundamental truths, a quest for a comprehensive understanding of the world, a study of principles of conduct, and much more.

Hope this helps
