Research in neuroaesthetics involves measuring brain activity, using technology like fMRI machines, when subjects look at works of art. It also involves looking at people with different brain disorders and seeing how this affects their ability to appreciate or create art. You might wonder how looking at someone’s brain can ever answer the big questions of aesthetics—like, what is beauty? Or, what is aesthetic taste? Isn’t neuroaesthetics just another attempt on the part of science to encroach on philosophy’s turf?
