Kennedy presents moral action as a willingness to do what one believes duty requires, even when the consequences are personally damaging. The emphasis is on conduct under pressure: obstacles, danger, criticism and possible loss do not remove the obligation to act according to conscience. In this sense, morality is shown not simply as a matter of belief, but as a test of whether principles are maintained when they become costly.

In Profiles in Courage, this idea is closely connected to political life. Kennedy examines public figures who accepted risks to reputation, office or career because they believed a particular course was right. The quotation therefore links personal integrity with public responsibility. Its broader claim is that moral character becomes most visible when duty conflicts with self-interest. Courage, in this account, is not the absence of danger or pressure, but the decision to act despite them.
