"Dogmatism" and Dogmatism

The so-called paradox of dogmatism has it that it seems that one is both entitled and not entitled to ignore evidence against what one knows. By knowing something, one knows it to be true, and one also knows that there can be no non-misleading evidence against what is true. But to ignore evidence against what one believes - and, surely, one believes what one knows - is to be dogmatic, something one should not be. I argue that there is no genuine paradox here. One's attitude to evidence is governed not by what one knows but by what one thinks one knows. Thinking that one knows something does not entail that it is true. Knowing this, one knows that there may be non-misleading evidence against what one thinks one knows and should be open to examining what purports to be evidence against it.
