But this proposition involves the contradictory of the former one. For wherever quarrelling is permissible, there must be a hope of mutual reconciliation; and consequently we can count on grounds of our judgement that have not merely private validity, and therefore are not merely subjective.

And to this the proposition, everyone has his own taste, is directly opposed.

There emerges therefore in respect of the principle of taste the following Antinomy: —

(1) Thesis. The judgement of taste is not based upon concepts; for otherwise it would admit of controversy (would be determinable by proofs).

(2) Antithesis. The judgement of taste is based on concepts; for otherwise, despite its diversity, we could not quarrel about it (we could not claim for our judgement the necessary assent of others).
