Two thousand years ago, Lucretius said that everything is atoms in the
void; it's physics all the way down. Contemporary physicalism agrees.
But if that's so how can we--how can our thoughts, emotions, our
values--make anything happen in the physical world?
This conceptual knot, the mental causation problem, is the core of the
mind-body problem, closely connected to the problems of free will,
consciousness, and intentionality. Anthony Dardis shows how to unravel
the knot. He traces its early appearance in the history of philosophical
inquiry, specifically in the work of Plato, Aristotle, Descartes, and T.
H. Huxley. He then develops a metaphysical framework for a theory of
causation, laws of nature, and the causal relevance of properties. Using
this framework, Dardis explains how macro, or higher level, properties
can be causally relevant in the same way that microphysical properties
are causally relevant: by their relationship with the laws of nature.
Smelling an orange, choosing the orange rather than the cheesecake,
reaching for the one on the left instead of the one on the right-mental
properties such as these take their place alongside the physical "motor
of the world" in making things happen.
