"Trotsky's most obvious gifts were his talents as an orator and as a writer. I regard Trotsky as probably the greatest orator of our age. ... His impressive appearance, his handsome, sweeping gestures, the powerful rhythm of his speech, his loud but never fatiguing voice, the remarkable coherence and literary skill of his phrasing, the richness of imagery, scalding irony, his soaring pathos, his rigid logic, clear as polished steel: those are Trotsky’s virtues as a speaker."
