Is the belief that mind, or consciousness, is omnipresent throughout the universe and is a fundamental aspect of the universe. Examples of panpsychic beliefs are that atoms have "atom consciousness", rocks have "rock consciousness", trees have "tree consciousness", planets have "planet consciousness" (see Gaia Hypothesis), and the universe has "universe consciousness", and so on. Panpsychism is sometimes called panexperientialism or panprotopsychism in contemporary Philosophy of mind.

Panpsychism, in philosophy, is either the view that all parts of matter involve mind, or the more holistic view that the whole universe is an organism that possesses a mind. It is thus a stronger and more ambitious view than hylozoism, which holds only that all things are alive. This is not to say that panpsychism believes that all matter is alive or even conscious but rather that the constituent parts of matter are composed of some form of mind and are sentient.
