2-55-7. Peter Guthrie Tait to H. Poincaré
I need scarcely say that I never dreamt of doubting the good faith of M. Poincaré. What I did (and still do) doubt is my having made my meaning clear to him. For I cannot see how such a discussion could degenerate into a mere war of words. So far as I understand myself, I have been dealing mainly with the validity of certain modes of establishing physical laws, not with the mere terms employed in describing the experimental facts on which they are founded.
