 A caution about how to set up the issue is in order. If you think that perceptual justification is only binary and does not come in degrees, you should avoid the following common formulation of that sort of view: either your experience justifies a belief that there is a snowman in the park or it does not. We can all agree that the law of excluded middle applies to perceptual justification, that doesn’t yet rule out the possibility that perceptual justification comes in degrees. For example, perhaps your experience justifies a belief when the degree of justification it gives is sufficiently high, and otherwise not. This is a scenario in which your experience either justifies a belief or it does not, as well as a scenario where perceptual justification comes in degrees.
