How Charles Richet might approach Biology

It is a marvelous thing that biology, the very science of life, should remain so stubbornly a science of the unknown. Let us consider the facts, gentlemen. When I first observed that a dog, having survived an injection of *Physalia* toxin, died within minutes upon a second, minuscule dose, I was not content to call it a mere accident. I repeated the experiment. I varied the doses. I changed the species. And there it was: a law of organic sensibility, anaphylaxis, hidden in plain sight. This is the method we must apply to all of biology.

We must not be afraid of the truth, however strange it may seem. The living organism is not a simple machine; it is a dynamic equilibrium of forces, many of which we have only begun to glimpse. From the cellular shock of anaphylaxis to the mysterious transmission of thought in telepathy, the same principle holds: the organism remembers, and that memory can be either protective or destructive. Experiment is the only guide. We must quantify, we must control, we must reproduce. But we must also dare to ask: what other sensitivities lie dormant in the protoplasm? What other latent powers of the living being await a rigorous, systematic inquiry?

The unknown is not the unknowable. Biology, properly pursued, must extend from the chemistry of the blood to the sociology of nations. If we can induce anaphylactic shock, can we not also induce immunity? If we can observe the inheritance of temperament, can we not, through careful selection, guide the evolution of our own species toward greater intelligence and peace? The same experimental logic that revealed the fragility of the dog before the jellyfish toxin must now be turned upon the great questions of human heredity and social organization. Let us not shrink from the task. The facts are…
