All real theories are the products of its time, and so is philosophy. Philosophy is the product of the times. On the one hand, it means that the emergence of any philosophical theory can not be separated from the individual philosopher who founded this philosophy, but fundamentally speaking, it can not be separated from the various conditions of its birth era; On the other hand, it also means that it is closely related to the needs of that era. Although some philosophical systems contain some elements of fiction and meditation, the background, content and value orientation of this philosophy are inseparable from the era when it was born.

Marxist philosophy pays special attention to the relationship between philosophy and the times, which is the inevitable product of its times. Marx once pointed out: "Any real philosophy is the essence of the spirit of its own era." This refers to "real philosophy", not any philosophy. Although all philosophy depends on its own times, it is not necessarily the essence of the spirit of the times. Only the philosophy that expresses the spirit of the times in the form of thought is the "real philosophy", such as17 ~18th century French materialistic philosophy,18th century late and19th century early idealistic philosophy of Kant and Hegel, while Marxist philosophy is the "real philosophy" of our time and the spirit of this time.
