I thought the brain catscan scenario settled this. A bunch of experiments are done with people tasting food saying what they think tastes good. A distiguishable pattern of neuron firings are observed for "good tasting food", providing me the opportunity to show to you with my brain catscan that I find the grapes taste good. What more is needed that that? And then, there is the scenario where we were joined at the head, sharing brain tissue, right :-) Philip Thrift http://www.paleofitness.com
