Is beauty just a biological function?
Want some rules for making "beautiful" art?
Neuroesthetics is the study of the electrical activity of the brain while looking at "beautiful" art.
I'm going to call it paint by dial!
In simple terms, does that mean we just wire up an EGG machine to an art critic's Prefrontal Cortex and watch the dial while we show them our work? :)
Alternatively, nature has already done it for us, we just need to mimic nature, where beauty comes from function i.e. where beauty is used for sexual purposes! For some background on this look at the writings of Associate Professor Michal Gibod.(google translation).
