"We have been carrying around the dualism of mind and body, soul and flesh for centuries or even millennia. Even before the results of biology and neurophysiology, this dualism was however dismantled by two great protagonists of modern philosophy: the rationalist Baruch Spinoza and the empiricist David Hume. Starting from very different premises, the two converge in telling us that our Io which claims to be immortal is nothing more than a mode of nature."
