 Judgments of beauty have, or make a claim to, “universality” or “universal validity”. (Kant also uses the expression “universal communicability”; this has been taken by many commentators as equivalent to “universal validity” but recently this has been questioned; see  Section 2.3.8.)  That is, in making a judgment of beauty about an object, one takes it that everyone else who perceives the object ought also to judge it to be beautiful, and, relatedly, to share one’s pleasure in it. But the universality is not “based on concepts”. That is, one’s claim to agreement does not rest on the subsumption of the object under a concept (in the way, for example, that the claim to agreement made by the judgment that something is green rests on the ascription to the object of the property of being green, and hence its subsumption under the concept green). It follows from this that judgments of beauty cannot, despite their universal validity, be proved: there are no rules by which someone can be compelled to judge that something is beautiful (Kant expands on this point in §§32–33). More strongly, judgments of beauty are not to be understood as predicating the concept beauty of their objects: as he puts it later, “beauty is not a concept of the object” (§38, 290). Still later, in the “Antinomy of Taste”, Kant seems to go back on this strong claim by saying that a judgment of beauty rests on an “indeterminate concept” (§57, 341); however, by “concept” here he diverges from the standard use of the term “concept” as referring to a kind of representation which can figure in cognition.
