Abstract

To believe a proposition wishfully is to believe it because one wants to believe it, and not because one has evidence or reason that it is true. Is it wise to be open to believing wishfully? After criticising one popular argument that we ought be closed to believing wishfully, I develop an argument that being closed to believing wishfully is to labour under a debilitating prejudice. As a rule, then, we ought to be open to believing wishfully. I find one and only one exception to this rule. People who value understanding things as they are, and value this more than anything else they value, are wise to be closed to believing wishfully.
