What is idealism and how to distinguish it?

idealism can be divided into subjective idealism and objective idealism.

1. Subjective idealism

Subjective idealism is one of the basic forms of idealism philosophy. Subjective idealism regards individual subjective spirits such as feeling, experience, mind, consciousness, concept and will as the root and foundation of the emergence and existence of everything in the world, and everything in the world is derived from these subjective spirits and is the manifestation of these subjective spirits. The so-called "mind is reason", "my mind is the universe", "nothing outside the mind" and "unreasonable outside the mind" in China's mind study in the Song and Ming Dynasties, and the so-called "being is perceived" and "things are a collection of ideas" in Bekele, England are representative and typical subjective idealism and solipsism. Subjective idealism logically leads to the conclusion of "solipsism", that is, everything in the world is only the expression of "I" feeling.

2. objective idealism

objective idealism is one of the two basic forms of idealism philosophy. Objective idealism holds that an objective spirit or principle is an ontology that exists before and independent of the material world, while the material world (or phenomenal world) is just the externalization or expression of this objective spirit or principle. The former is original and primary, while the latter is derived and secondary.
