Charles L. Stevenson coined the term "persuasive definitions" (Ethics and Language, 1944). It means: to apply words with favorable or unfavorable connotations to things or actions in such a way as to substitute for actual argument. Examples abound in political discourse nowadays.
I'll focus on just one: "invest." Politicians repeatedly tell us Americans to "invest" in our children, education, job retraining, medical and other research, defense, infrastructure, a healthy environment, clean energy, energy independence, transportation, progress, the future — whatever. Here "invest in" means "have the government spend more money on." More fully, it means "have the government spend more money on such things — money raised by taxes and by increasing the national debt."
