The wine itself has aesthetic value; but what it is for a wine to have aesthetic value cannot be understood without making reference to the experience to tasting it

I do think that if you are trying to think empirically about the relationship between conscious experience and the underlying physical reality, wine provides an excellent practical example. Winemakers manipulate the chemicals they are dealing with in a way that is very sensitive to the kinds of effects it will have on the subjective experience of tasters - this is not an accident.

The thing I think I have learned from Wittgenstein is the importance of not making things up: philosophers should not invent problems, and they should also be conscious of the risk of inventing pointless 'technical' machinery which do not offer real explanations, but often just re-state the known facts in a more complex way.

One odd thing about the current debate between religious people and atheists is that the participants don't seem to care that they entirely fail to communicate with the other side. They therefore have no account of why the religious or the atheists believe what they do, except that they are stupid or deluded. I think philosophers should try and make sense of their disputes with their opponents as far as possible without treating them as idiots. This applies to the religious participants in the debate as much as to the atheists.

Many people like to think that their moral or political enemies are not just wicked or wrong - as if that were not enough - but stupid or idiotic too. We tend to find this attitude too in the contemporary religion debate. It might console those on each side of the debate to think of their opponents in these terms, but if we want to make real progress in understanding what is going on here, this approach cannot help.

I do think that philosophy and science are very different intellectual enterprises, but that does not mean that when we get knowledge from philosophy it is a different kind of knowledge.

Unlike art which contains a message, wine conveys nothing, it has no intellectual or cognitive content
