I have already sent to be printed the most formal declaration of war.[379] There is no longer any room for diplomacy here -- of course, I am speaking of diplomacy not in the bad sense, but in the good sense of the word.
"Good" diplomacy on your part, dear A. M. (if you, too, have not come to believe in God), should consist in separating our joint (i.e., including myself) affairs from philosophy.
A talk on other matter than philosophy won't come off now: it would be unnatural. Incidentally, if these other matters, not philosophical, but Proletary matters, for example, really demand talks just now, and at your place, I could come (I don't know whether I shall find the money: there are difficulties at present), but I repeat: only on condition that I do not speak about philosophy or religion.
And I definitely intend coming to have a talk with you when I am free and through with my work.
All the very best.
Yours,
Lenin
Best regards to M. F.: she is not for God, by any chance, is she?
