Philosopher and wine enthusiast Barry Smith samples David Hume's theory of good taste. The 18th century Scottish philosopher argued that the appreciation of beauty was not easily arrived at - it required dedication, knowledge, expertise. In that sense he is the godfather of the critic and the patron saint of the connoisseur. As he delves into our sense of 'good taste' Barry recounts a wine laden tale from Don Quixote, talks to Neuroscientist Semir Zeki and to Art Historian Liz Prettejohn.
