Sometimes panpsychism is understood as any belief that maintains that everything is psychical, mental, spiritual in nature, but traditionally it is understood to mean a certain pluralistic form of idealism. Idealists differ, however, about how many distinct minds there are.
Absolutists say that there is but one mind of which the apparent many are parts or functions.
Pluralistic idealists declare that nature is the active experience of one ultimate mind, but that an indefinitely large number of nondivine minds also exist. Panpsychism adds further to the mind population of the universe, for in addition to the persons and selves recognized by pluralistic personalists, the panpsychists find an elementary monad or self or mind cell for every minute constituent of nature. But, for all idealists mind or personality is the model on which all reality is constructed. The view has been accepted by a good many philosophers and scientists. The constituents of this world are, for panpsychists, just as real as human minds or as any mind.
