What is Concrete, What is Abstract?July 2, 2021
Dialectically dependent categories reflecting the knowledge of the whole and its parts. In dialectical materialist philosophy, the knowledge of the concrete, the whole, and the objective reality; abstract expresses the incomplete knowledge of the parts. Concrete is a concept that expresses both the holistic truth grasped by the senses and the truth of this truth realized in human consciousness. In the process of scientific knowledge, the concreteness of the knowledge is reached by starting from the concreteness of the object.
It gives the meaning of “limited knowledge” in idealist philosophy, as a concept opposed to the concrete, which is claimed to express what is grasped by the senses, and in abstract, dialectical philosophy, which is claimed to express only what is grasped by thought. In other words, it reflects the objective reality of what is missing, or in other words, the part, as a form of knowledge in abstract, dialectical philosophy, which is only found in thought in idealist philosophy. In the process of scientific knowledge, in order to reach a concrete knowledge from the concreteness of the object (in other words, to reflect the concreteness of the object in concepts), it goes from abstract to concrete. This means that starting from the concreteness of the object, that object is recognized in its parts and in the relations between its parts, concepts that reflect all the aspects and properties of the object are obtained, a system of concepts is formed from these concepts, and objective concreteness is re-established as conceptual concreteness.
This process of knowledge also includes going from the concrete to the abstract, because knowing the whole requires knowing the part, and knowing the part requires knowing the whole. Scientific knowledge is the reflection of objective reality in concepts. But these concepts are not concepts abstracted from objective reality, as in the abstraction approach of idealist philosophy, but are concepts that reflect objective reality. The concretization of the abstract in dialectical philosophy means the conceptualization of the object. This expresses his raising to the level of knowledge.
