A Letter to James P. Cannon [1]¶
Core Argument¶
In this letter of 15 December 1939, Leon Trotsky addresses James P. Cannon, a leading figure in the American Socialist Workers Party, during a period of intense internal factional struggle. The core argument is that the opposition within the party has refused to engage on a principled, theoretical plane, instead seeking tactical recipes for immediate “concrete” questions. Trotsky dismisses this demand outright, refusing to write a “cookbook for the epoch of imperialist wars.” He insists that correct solutions to concrete problems—however complex—can only be derived from a firm principled approach to fundamental questions. The Finnish question is cited as a specific instance where the opposition’s incapacity to think from first principles led to error.
Trotsky anticipates the opposition’s defensive responses: that his analysis is too distant from the party’s day-to-day life, that it “ascribes” ideas to them they never held, and that not all petty-bourgeois elements are with the opposition nor all workers with the Majority. He counters these objections by arguing that no faction is ever chemically pure; the decisive issue is which social layer “sets the tone.” In the opposition, he asserts, the tone is set by petty-bourgeois elements. The charge of ascribing false ideas, he explains, arises not from misrepresentation but from the “formlessness and contradictory character” of the opposition’s own ideas, which cannot withstand critical analysis. The article in question, he claims, merely develops those ideas to their logical conclusion.
The letter draws on the Marxist method of analysing factional struggle through the lens of class composition and theoretical clarity. It is a polemic against empiricist and pragmatic tendencies within the Trotskyist movement—those who would substitute tactical improvisation for revolutionary theory. Trotsky also implicitly defends his own role as an observer from exile, arguing that the general traits of a struggle can often be seen more clearly from the sidelines. The letter is a sharp intervention in a faction fight, insisting that the opposition’s refusal to ground itself in principle is itself a political position, and a dangerous one.
