“Kautsky is pursuing a characteristically petty—bourgeois, philistine policy by pretending (and trying to make the people believe the absurd idea) that putting forward a slogan alters the position. The entire history of bourgeois democracy refutes this illusion; the bourgeois democrats have always advanced all sorts of “slogans” to deceive the people. The point is to test their sincerity, to compare their words with their deeds, not to be satisfied with idealistic or charlatan phrases, but to get down to class reality.”
– Lenin, “The Proletarian Revolution and the Renegade Kautsky”
