Phenomenal worlds and nervous systems.

Here’s a little paper I just wrote about the relation between P-worlds and nervous systems.

Here’s the abstract:

The epistemological situation of a single cell is considered.
In chemotaxis, the relation between perception and action is
found to be lawful and bidirectional. Consideration of the
perception/action relation allows a characterization of the phe-
nomenal world of the cell that is grounded in perceptual dis-
tinctions that are relevant to its sustained viability. Moving
up the phylogenetic chain, this lawfulness, and its relation to
the phenomenal world of experience, is found to be essentially
unchanged in multicellular organisms. Nervous systems add
some innovation, in allowing distal responses and the non-
linear combination of information, but from cell to human,
the differentiation of the phenomenal world is found to arise
from the lawfulness of the perception/action relation, which in
turn reflects the biological constitution of the organism, and
not a pre-given objective world. This recognition suggests
that rather than looking within the nervous system for repre-
sentations of pre-given, external, entities, one might do bet-
ter to explore the fit between the function of the nervous sys-
tem and the phenomenal, meaningful, world encountered by
the organism in experience.
