People can have various reasons for studying philosophy.

If we divide this into four reasons, they can be explained as 'luxury goods', 'escape', 'intellectual curiosity', and 'self-fulfillment'.

First, those who study philosophy as a luxury good are trying to satisfy their intellectual vanity. They seek to stand out through philosophy and claim to study it deeply to gain social interest and recognition.

Philosophy serves to make oneself more special, like an expensive luxury item. They use studying philosophy merely as a means to show off to others.

Second, those who study philosophy as an escape rely on it to get away from life's difficulties or problems. For example, they claim to explore the essence of life through philosophy to escape from predicaments such as breakups, divorces, or layoffs.

Philosophy can also be used as a means to avoid real-life problems. This reflects a desire to transcend specific life issues by utilizing philosophy as a metaphysical approach.

Third, those who study philosophy out of intellectual curiosity do so purely for the pleasure of intellectual stimulation. They do not use philosophy as an escape or luxury good, but rather enjoy the sense of achievement in fulfilling their intellectual curiosity and experience pleasure through a reversal of existing ways of thinking.

Philosophy is like a dramatic twist in itself, providing astonishing thoughts that break existing notions, leading to intense intellectual joy.

Finally, philosophy goes beyond mere theoretical study to construct a mental world. Philosophers create their own worldview and seek to transcend existing worldviews through it.

Philosophy forms a system in itself, and within that system, it creates a new world that overturns previous notions.

This is not merely a reversal of thought but a process of building a new system of thought, which can provide a more intense intellectual pleasure for those with a thirst for knowledge than philosophy itself.

Therefore, the reason for studying philosophy is not simply intellectual vanity, escape from reality, or using it like a toy, but rather a deep exploration of human existence and the world, as well as an intellectual journey to build a new system of thought.
