Note 740 — Chapter X · JUDICIAL REVIEW
Reading edition
249 U. S. 47 (1919). Holmes’ reasoning was perhaps based on J. S. Mill’s analysis in his essay “On Liberty:” “No one pretends that actions should be as free as opinions. On the contrary, even opinions lose their immunity when the circumstances in which they are expressed are such as to constitute their expression a positive instigation to some mischievous act.” On Liberty (New York: Dutton, 1950), Ch. III, p. 152.
