panpsychism

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. The view that all matter has consciousness.

Century Dictionary and Cyclopedia

1. n. The doctrine that the entire universe, or any least subdivision of it, has a mental as well as a physical side or aspect, and that the mental side stands to the physical (for instance, in the atom), precisely as human consciousness stands to the human body. Panpsychism may be monistic, reducing all reality to ultimate mental terms, or dualistic; and, if the latter, may receive an interactionist or a parallelistic interpretation. It is represented in ancient philosophy by hylozoism, has persisted in various forms throughout the history of philosophy, and finds acceptance among the moderns, for example, with G. T. Fechner.
