Brainethics has a very nice post introducing bioaesthetics, a field that endeavours to use "neuroscience to understand art and aesthetic behaviour". I'd like to take this opportunity to jump up on my soapbox and ask, what exactly do we want biology (or neuroscience) to say about art ? What are the questions that biology can hope to answer and art history or aesthetics cannot ?
