A Letter to Martin Abern

Core Argument

Here, Trotsky addresses a factional dispute within the Socialist Workers Party (SWP) by responding to Martin Abern’s denial of a reported remark. The core of the chapter is a procedural and political defence of how Trotsky handled a piece of hearsay in an internal party struggle. Trotsky’s narrative thrust is to justify his method of publishing an unverified report—that Abern allegedly said “This means split” upon reading a document—while simultaneously accepting Abern’s categorical denial and elevating the question of splits to a matter of principle.

Trotsky’s key claim is that he acted correctly by publishing the report with the caveat “it has been reported,” thereby giving Abern the opportunity to confirm or deny it. He argues that this is the “best checking possible in a party discussion,” rejecting the notion that he should have privately verified the claim before publication. The evidence he relies on is a letter from James P. Cannon, whom Trotsky describes as “a trustworthy comrade.” Trotsky does not retreat from his reliance on Cannon’s word; instead, he frames the entire episode as a normal hazard of “sharp fight,” where misunderstandings occur “without bad will.”

The historical context is the bitter factional struggle inside the SWP in 1939-40, which revolved around the party’s orientation toward the Soviet Union and the nature of the Russian state. Trotsky was in exile in Coyoacán, Mexico, intervening by correspondence. The chapter draws on the Leninist tradition of democratic centralism, where internal debate is conducted openly but with a strict prohibition on splitting the party. Trotsky’s polemical target is not only Abern’s denial but also the vague and insinuating language Abern used in his own letter. Trotsky turns the tables by demanding that Abern specify what “false statements” and “other things” he means, accusing him of using “vague insinuations” that could mislead “inexperienced comrades.” He also rebukes Abern for claiming to have “disregarded” false statements, suggesting that such disregard is a “lack of attention toward the party.”

The chapter concludes with Trotsky accepting Abern’s denial, but only after redefining its significance: he interprets Abern’s “energetic tone” as meaning that Abern shares Trotsky’s view that the idea of a split is a “despicable betrayal of the Fourth International.” This is a political trap: by accepting the denial on his own terms, Trotsky forces Abern to publicly renounce not just the quote but the very concept of splitting, thereby binding him to Trotsky’s factional line.
