We can produce an idea in the theatre of the imagination. We can test it out against our other ideas, the ideas of others, or the world itself. If it falls short, we can let it go. We can, in Popper’s formulation, let our ideas die in our stead.147 Then the essential part, the creator of those ideas, can continue onward, now untrammeled, by comparison, with error. Faith in the part of us that continues across those deaths is a prerequisite to thinking itself.
