It is argued that the natural kinematics of the pilot-wave theory is A
ristotelian. Despite appearances, Galilean invariance is not a fundame
ntal symmetry of the low-energy theory. Instead, it is a fictitious sy
mmetry that has been artificially imposed. It is concluded that the se
arch for a Lorentz-invariant extension is physically misguided. (C) 19
