It's necessary to address the concerns and beliefs of those who are taken in by the fraud, or who don't recognize the nature and significance of the issues for other reasons. If by philosophy we mean reasoned and thoughtful analysis, then it can address the moment, though not by confronting the "alternative facts" but by analyzing and clarifying what is at stake, whatever the issue is. Beyond that, what is needed is action: urgent and dedicated, in the many ways that are open to us.
