Abstract
The problematic nature of the relation between a politicized historical rhetoric and the presumed authority of brute fact was starkly outlined in the irreconcilable interpretations of the purge trials that tore apart the political Left in the 1930s. The conclusions of the Commission, headed by John Dewey, on the mock trial of Leon Trotsky in Mexico City in April 1937 rested on the evidence of the factual fabrications of key confessions. The critical contemporary responses were more or less predictable in light of political partis pris. They either disparaged the entire procedure as a Trotskyite "court," where the driving purpose was to acquit Trotsky of guilt, deftly disposed of the key factual allegations, or saw the trial as attacking the Soviet system of justice itself, thus making irrelevant Trotsky's actual guilt or innocence. We now find the Commission's conclusions more persuasive than those of William Z. Foster, Malcolm Cowley, or F. L. Schuman not because of their superior tropological strategies, nor because of a skillful parade of rhetorical figures, nor because of the hermeneutic fusing of historical horizons, but because they satisfy familiar criteria of empirical inference and rational discourse
