Even worse is the second term of the question, “matter.” It is, as well, the residue of an incorrect metaphysics based on too naive a conception of matter as a universal substance defined only by mass and motion. This is erroneous metaphysics because it is contradicted by quantum physics. If we think in terms of processes, events, in terms of relative properties, of a world of relations, the hiatus between physical phenomena and mental phenomena is much less dramatic. It becomes possible to see both as natural phenomena generated by complex structures of interactions.
