Abstract
I argue that, from the liberal perspective, citizens have a pro tanto moral duty to cultivate and maintain a readiness to participate in politics when such an action is called for from the moral perspective—I will call it “the pro tanto duty of political engagement.” It requires a citizen to monitor what the government is doing, evaluate its actions, and learn what she can do to intervene politically. In Section 1, I will discuss some doubts on the pro tanto duty of political engagement. In Section 2, I will describe Alexander Guerrero’s account of culpable ignorance and argue from his account that the pro tanto duty of political engagement is derived from a general moral duty to properly manage one’s morally relevant beliefs. In Section 3, I will argue that to properly assess the moral significance of any government policy or policy proposal, one must learn about the lives and personal values of those who would be affected by the policy.
