Panpsychism is a philosophical doctrine that believes everything has consciousness and mental states. It is a complex term, and there are many synonyms that can be used to describe it. One such term is panexperientialism, which acknowledges the presence of consciousness and experience in all things. Another synonym is hylozoism, which believes that every object in the universe is animated by a vital principle or soul. Mind-body dualism, which posits that the mind and body are separate but interact with each other, is also considered a form of panpsychism. Other similar terms include animism, vitalism, and animatism. Despite their differences, all these terms share a fundamental belief in the presence of consciousness and life in all things.
