He claims that the way we study complex systems, like those in biology, simply can't be reduced to physics. Then he goes on to claim that the first Newton law doesn't apply to biology: but when we look at the biological world, matter seems to move by itself all the time. This is simply not true. If it was true then we could also claim that any chemical process (that is governed by physics) can't be reduced to physics. Which obviously we know to be not true.
