Query: On the compatibility of causality and symmetry (Comments on "Analysis of
  causality in time-dependent density functional theory")   It is argued that there exists the only one inverse of the linear response
function $\chi$, i.e. $\chi^{-1}$, which depends symmetrically of its
spatial-times variables, see M.K. Harbola, and A. Banerjee, Phys. Rev. A {\bf
60}, 5101 (1999). Some brief comments on this consideration are presented. We
show instead, that it is possible to construct the causal inverse also. At the
same time we confirm the main statement of M.K. Harbola and A. Banerjee that in
fact there is no contradiction between the symmetry and causality.
