What is the order of scientific development?

Examples of human cognitive development are as follows:

1, phenomenological stage. It mainly describes observation phenomena and experimental results, and the individual facts described are equivalent to individual judgments in Hegel's conceptualism, which is a comfortable stage of scientific understanding.

2. The ontological stage. This paper mainly combs the description of related phenomena, explores the substantive structure of the phenomena and seeks regular knowledge. What it seeks is the special phenomenon of special entity structure under special circumstances, which is equivalent to the special judgment in Hegel's concept theory and is the stage of scientific understanding.

3. Essentialism stage. It mainly reveals the law of interaction between entities, which is equivalent to the general judgment in Hegel's concept theory and is the stage of scientific understanding. Scientific understanding generally develops circularly in the order of these three stages. The three-stage logical development sequence of human understanding of natural science is determined by the structure of phenomena, entities and essence of nature itself.
