“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…” quote by Niels Kaj Jerne

“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.”

About This Quote

This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.

The immune system can generate specific antibodies without nervous input, showing language‑like complexity and independent cognition.

In simple terms: Immune cells create antibodies on their own, similar to language.

Key Takeaway

Recognize the brain‑independent intelligence of immunity.
