Letter to Frederic H. Hedge
p113“Mr Ripley would have written you a better, but he is too busy fighting the battles of Spinoza and other infidels.”
Fuller, Margaret. The Letters of Margaret Fuller. Edited by Robert N. Hudspeth. Vol. II. Ithaca: Cornell University Press, 1984.
Inferred Fuller references Ripley's defense of Spinoza in his pamphlet controversy with Andrews Norton, employing a light tone ("fighting the battles of Spinoza and other infidels") that suggests her familiarity with the dispute; as Hudspeth identified.
