introspection soon proves as hostile to the idea as the lawas of physics are?

Does " introspection soon proves as hostile to the idea as the lawas of physics are" mean " introspection soon proves as hostile to the idea (of free will) as the lawas of physics are hostile to the idea (of free will)"?

Context:

The popular conception of free will seems to rest on two assumptions: (1) that each of us could have behaved differently than we did in the past, and (2) that we are the conscious source of most of our thoughts and actions in the present. As we are about to see, however, both of these assumptions are false.

But the deeper truth is that ree will doesn't even correspond to any subjective fact about us - and introspection soon proves as hostile to the idea as the lawas of physics are.
