The Anti-essentialism in modern and contemporary philosophy is wrong to oppose all essences. We should only oppose essences in the objective world, not in the subjective world. Anti-essentialism pours out the dirty water and the child after bath, while Neo-essentialism advocates pouring out the dirty water and leaving the child behind.
It is difficult to create correct philosophical theories. Although all philosophical theories in history have mistakes, they provide the foundation for creating correct philosophical theories. The creation of a correct philosophical theory requires the foundation of three aspects: dogmatic Metaphysics, Epistemology and Meta-ethics. Only after these three aspects have been fully developed can Metaphysics be rebuilt. The subject of this Metaphysics is Neo-essentialism.
The essence believed by the old and the new Essentialism is completely different, so the truth view of the old and new Essentialism will be completely different. New Essentialism holds that essence is artificial and therefore fallible. In this way, essence is not a supreme principle of action or a standard of truth, but a tool by which we understand and transform the world. Neo-essentialism is pragmatism, the ultimate principle of behavior is value maximization, the ultimate standard of truth is usefulness, which means valuable. Value is embodied in practice, so the standard of truth is practice. The old Essentialism regarded the Dao Li of the objective world as supreme, so it must take these objective Dao Li as essence, and take these essence as the ultimate principle of action and the ultimate standard of truth. If these principles contradict people's interests, then we must preserve objective principles and destroy human desires. All kinds of man-eating legal institutions in history were the inevitable result of the development of old Essentialism. Old Essentialism was also the theoretical source of many religions, such as Christianity from Plato's Essentialism, Daoism from Laozi's Essentialism.
