I am a child of the poisonous wind that copulated with the East River on an oil-slick, garbage infested midnight. I turn about on my own parentage. I inoculate against those very biles that brought me to light. I am a serum born of venoms. I am the antibody of all Time. I am the Cure. You do of the City, do you not? Manhattan is your punisher, let me be you shield.
An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system has evolved and functions without assistance of the brain.
Fundamentalism in most of its forms is the active creation of antibodies to some threatening [god] virus. As long as threatening religions or mutations [heresies] are present, fundamentalism will churn out antibodies to keep the population under control and prevent mutations from getting out of hand.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences. The secret of antibody diversity would emerge from that. Fortunately at the time I was sufficiently ignorant of the subject not to realise how naive I was being.
