  The aim of this work is to offer a general theory of reciprocity laws for
symbols on arbitrary vector spaces, and to show that classical explicit
reciprocity laws are particular cases of this theory (sum of valuations on a
complete curve, Residue Theorem, Weil Reciprocity Law and the Reciprocity Law
for the Hilbert Norm Residue Symbol). Moreover, several reciprocity laws
introduced over the past few years by D. V. Osipov, A. N. Parshin, I. Horozov,
I. Horozov - M. Kerr and the author -together with D. Hern\'andez Serrano-, can
also be deduced from this general expression.
