The analysis of matter

This work undertakes a philosophical examination of modern physics, analyzing its logical structure and implications for matter, space, and perception. It surveys relativity and quantum ideas, then traces how physical theory grows out of ordinary perception by treating measurement, hypotheses, causality, and the primacy of structural relations over substance. Physical entities are presented as constructions of events and relations in space-time rather than enduring material substrata; points, causal lines, invariants, and geodesics are developed to support this view. The argument culminates in a neutral monist account that aims to place mind and physical description on a common ontological footing and to clarify scientific method.
