A recent innovation in quantum field theory is the locally covariant
framework developed by Brunetti, Fredenhagen and Verch, in which quantum
field theories are regarded as functors from a category of spacetimes to a
category of *-algebras. I will review these ideas and particularly discuss
the extent to which they correspond to the intuitive idea of formulating the
same physics in all spacetimes.
