Materialisme vs. idealisme…

Hegel can deny that this raw information amounts to knowledge, but he cannot deny that it suggests the existence of something outside mind itself. The same point holds even more obviously for the view that mind shapes the world practically by working upon it. Michelangelo may have thought of David, taken a lump of marble, and turned it into a statue that accorded with his thoughts; but he would not have got far if there had been no marble in the first place.
