Empiricism is an epistemological theory, which was born in ancient Greece and emphasizes the understanding of feelings. Empiricism holds that all knowledge can be obtained through experience (perceptual experience) and can be verified through experience.

? There are two kinds of empiricism, one is materialistic empiricism and the other is idealistic empiricism. Like the British educator Locke's "mind whiteboard" is materialist empiricism. He believes that the mind can distinguish and summarize feelings and impressions by observing things and gaining all experiences.

? So as far as psychology is concerned, it is easy to accept empiricism. In the United States, Britain and other countries, empiricism is gradually strengthened, and the dominant trend is obvious, but new theories are also impacting empiricism, such as quantum mechanics.
