Immune System Quotes (2 quotes)
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 absence 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.
I would picture myself as a virus, or as a cancer cell, for example, and try to sense what it would be like to be either. I would also imagine myself as the immune system, and I would try to reconstruct what I would do as an immune system engaged in combating a virus or cancer cell. When I had played through a series of such scenarios on a particular problem and had acquired new insights, I would design laboratory experiments accordingly Based upon the results of the experiment, I would then know what question to ask next When I observed phenomena in the laboratory that I did not understand, I would also ask questions as if interrogating myself: Why would I do that if I were a virus or a cancer cell, or the immune system? Before long, this internal dialogue became second nature to me; I found that my mind worked this way all the time.
