All true theories are products of their time, and the same is true for philosophy. The so-called philosophy is the product of the times. On the one hand, it means that although the emergence of any philosophical theory is inseparable from the individual philosophers who founded this philosophy, it is fundamentally related to the various conditions of the era in which it was produced. Inseparable; on the other hand, it means that it is closely related to the needs of that era. Although some philosophical systems contain certain elements of fabrication and meditation, judging from the background of this philosophy as well as its content and value orientation, it is inseparable from the era in which it was produced.
Marxist philosophy attaches special importance to the relationship between philosophy and the times, and it itself is an inevitable product of its times. Marx once pointed out: "Any true philosophy is the essence of the spirit of its own time." This refers to "real philosophy", not just any philosophy. Although all philosophy depends on its own era, it may not be the essence of the spirit of the times. Only philosophy that expresses the spirit of the times in the form of ideas is "real philosophy", such as the French materialist philosophy of the 17th to 18th centuries, the idealist philosophy of Kant and Hegel in the late 18th and early 19th centuries, and the Marxist philosophy , it is the "real philosophy" of our time and the essence of the spirit of this time.
