Hank Harrison - Hume

How could Hume possibly have felt like he was on to anything when he was trying to quantify exactly what makes something beautiful? I've never been much of a fan of Hume's works, but with art I feel he is especially misguided. He even contradicts himself regularly. For example, when he says that beauty is objectively based somewhere, how then can he say there will be disagreements? If beauty is objective and universal, that would mean there are no disagreements on what is beautiful. Hume says these differences would be based on either cultural influences or psychological influences. In my opinion, this is Hume copping out of having to admit his original premise is totally incorrect. It sounds to me like he wants so badly to value his "sentiments" as the source for beauty that he cannot figure out a way to explain things in a more coherent manner.
