In philosophy, panpsychism is the view that all matter has a mental aspect, or, alternatively, all objects have a unified center of experience or point of view. Baruch Spinoza, Gottfried Leibniz, Gustav Theodor Fechner, Friedrich Paulsen, Ernst Haeckel, Charles Strong, and partially William James are considered panpsychists.
Panexperientialism, as espoused by Alfred North Whitehead, is a less bold variation, which credits all entities with phenomenal consciousness but not with cognition, and therefore not necessarily with full-fledged minds.
Panprotoexperientialism is a more cautious variation still, which credits all entities with non-physical properties that are precursors to phenomenal consciousness (or phenomenal consciousness in a latent, undeveloped form) but not with cognition itself, or with conscious awareness.
