I argue that rationally persuading another to do something for their own good is sometimes (objectionably) paternalistic. Rational persuasion may express, and be guided by, the motive of distrust in the other’s capacity to gather or weigh evidence, and may intrude on the other’s deliberative activities in ways that conflict with respecting their agency and autonomy. I also examine factors that make a difference to whether (and when) the provision of reasons is respectful.
