 Kant’s idea is that in a judgment of taste, we demand or require agreement from other human beings in a way we do not in our judgments about the niceness of Canary-wine, which is just a question of individual preference. In matters of taste and beauty, we think that others ought to share our judgment. That is why we blame them if they don’t. It is because the judgment of taste has such an aspiration to universal validity that it seems “as if [beauty] were a property of things”.
