I often find myself thinking what really distinguishes Humans apart from other animals. If it is intelligence (high or low is irrelevant, it is still an inelegance) then this statement isn't true since we know that there are numbers of highly intelligent species including birds (non-mammal). So I came to conclusion that the only thing that does separate us is art, or perhaps understanding the value of art. But to contradict myself I keep flashing back on various images and video clips of cats or other animals "painting" on the canvas. Do you think in your philosophical opinion do these animals go through similar (high or low is irrelevant) process of appreciating art.
