It is not easy to say how we categorize things like red roses as beautiful. The beauty of the roses is not out there in the world, as the roundness and flatness are in the plates. If it were, then we would not get into so many disagreements of taste. And yet there is some sort of basis for claiming that the roses are beautiful. After all, there is quite a lot of human agreement that roses are beautiful and that cockroaches are ugly. Hume tried to resolve this problem by saying that judgements of taste are ‘intersubjective’: people with taste tend to agree with each other. Kant believed that judgements of beauty were universal and grounded in the real world, even though they were not actually ‘objective’. How could this be?
