The first commonplace of taste is contained in the proposition, with which every tasteless person proposes to avoid blame: every one has his own taste. That is as much as to say that the determining ground of this judgement is merely subjective (gratification or grief), and that the judgement has no right to the necessary assent of others.
The second commonplace invoked even by those who admit for judgements of taste the right to speak with validity for every one is: there is no disputing about taste. That is as much as to say that the determining ground of a judgement of taste may indeed be objective, but that it cannot be reduced to definite concepts, and that consequently about the judgement itself nothing can be decided by proofs, although much may rightly be contested. For contesting [quarrelling] and disputing [controversy] are doubtless the same in this, that by means of the mutual opposition of judgements they seek to produce their accordance; but different in that the latter hopes to bring this about according to definite concepts as determining grounds, and consequently assumes objective concepts as grounds of the judgement. But where this is regarded as impracticable, controversy is regarded as alike impracticable.
We easily see that between these two commonplaces there is a proposition wanting, which, though it has not passed into a proverb, is yet familiar to every one, viz. there may be a quarrel about taste (although there can be no controversy). 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, every one 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).
