… is from page 69 of Harold Stearns’s 1919 book, Liberalism in America; I’ve not read this book, but found this quotation from it on page 451 of Hayek’s 1960 volume, The Constitution of Liberty (emphasis original to Stearns):
Coercion for the sake of virtue is as repugnant as coercion for the sake of vice. If liberals are unwilling to fight the principle of coercion in the case of the Prohibition Amendment simply because they personally are not much interested in whether the country is dry or not, then they are discredited the moment they fight coercion in those cases where they are interested.
