  I critically discuss two dogmas of the "dynamical approach" to spacetime in
general relativity, as advanced by Harvey Brown [Physical Relativity (2005)
Oxford:Oxford University Press] and collaborators. The first dogma is that
positing a "spacetime geometry" has no implications for the behavior of matter.
The second dogma is that postulating the "Strong Equivalence Principle"
suffices to ensure that matter is "adapted" to spacetime geometry. I conclude
by discussing "spacetime functionalism". The discussion is presented in
reaction to and sympathy with recent work by James Read ["Explanation,
geometry, and conspiracy in relativity theory"(20??) Thinking about Spacetime.
Boston: Birkauser].
