In a recent Comment [I. Brevik and S. A. Ellingsen, Phys. Rev. A 79, 027801 (2009)], our position that the calculation of dispersion forces should be based preferably on the Lorentz force (or, equivalently, on Maxwell's stress tensor) is put into question, and it is argued that one should resort to Minkowski's stress tensor instead. After sketching briefly our reasons for preferring the Lorentz force, we point out that by use of Minkowski's stress tensor additional, compensatory force components are included in the calculation, but inconsistently. We consider the electrostatic arguments given in support of Minkowski's tensor in the Comment as unconvincing, and we point out that the issue of divergences raised in the Comment in the context of planar setups is not specific to Maxwell's stress tensor.
