Extended information

Subjective idealism regards everything in the external world as the manifestation and product of one's own subjective spirit. In fact, it is believed that everything in the external world is determined by the subjective spirit of each self. Without the subjective spirit of each conscious self, there would be no things in the external world, that is, the existence of the objective world depends on the subjective spirit.

The views of Chinese Lu Jiuyuan’s “my heart is the universe” and the British Berkeley’s so-called “existence is to be perceived” and “objects are a collection of ideas” are representative and typical subjective idealist point of view.
