I dont think cows require rembrant, but to a cow rebrant probably looks like pointless smudges...
Similarly there is probably a cow mooing his heart out that sounds like a symphony to another cow, an inspiration with beauty and depth like no other.. but to us it just sounds like a moo.
I dont think a cows depth of beauty is any less, just different.
Obviously I disagree, but as we covered i dont think its something we could prove too easily either way.
I've seen them cry, ive seen them happy, I've seen them express all the emotions we do at least.
