Continuing our
look at the critics of Thomas Nagel’s recent book Mind
and Cosmos, we turn to philosopher Alva Noë’s very interesting remarks over
at NPR’s 13.7: Cosmos & Culture blog.
Noë’s initial comments might seem broadly sympathetic to Nagel’s
position. He writes:
Science has produced no standard
account of the origins of life.
We have a superb understanding of how
we get biological variety from simple, living starting points. We can thank
Darwin for that. And we know that life in its simplest forms is built up out of
inorganic stuff. But we don't have any account of how life springs forth from
the supposed primordial soup. This is an explanatory gap we have no idea how to
bridge.
Science also lacks even a
back-of-the-envelop [sic] concept explaining the emergence of consciousness
from the behavior of mere matter. We have an elaborate understanding of the
ways in which experience depends on neurobiology. But how consciousness arises
out of the action of neurons, or how low-level chemical or atomic processes
might explain why we are conscious — we haven't a clue.
We aren't even really sure what
questions we should be asking.
These two explanatory gaps are
strikingly similar… In both cases we have large-scale phenomena in view (life,
consciousness) and an exquisitely detailed understanding of the low-level
processes that sustain these phenomena (biochemistry, neuroscience, etc). But
we lack any way of making sense of the idea that the higher-level phenomena
just come down to, or consist of, what is going on at the lower level.
