I've been reading Gary Cziko's _The Things We Do_ (2000. MIT Press.
Cambridge, Massachusetts, ISBN 0-262-03277-5). He talks about circular
causation and physiological homeostasis where effects supposedly feedback to
causes, a view less simplistic than the standard unidirection linear cause
leads to effect view. Not too bad of a book so far, but I could not pass up
this particular quote (p. 178-9):
(bq) "The human immune system's primary function is to protect our bodies
from microscopic pathogens such as bacteria, viruses, and chemical toxins
that are collectively known as *antigens*. It does this by producing cells
called *antibodies* that are able to recognize invading antigens and bind
with them so that other cells produced by the immune system can find and
neutralize or destroy them." (eq)
There's something not quite right with this passage considering that
antibodies are proteins and that cells known as B-lymphocytes produce
antibodies. I'm not sure you can equate pathogens with antigens. If I'm not
mistaken, antigens are molecules and as such could be contained by a
pathogen. A given pathogen could contain more than one antigen.
This gaffe aside the larger point in this part of Cziko's book of
intraselection operating within an organism over its lifetime was not lost.
