Uncertainty for Everyone The one thing that is certain about the world is that the world is uncertain. I have here, the question that apart of the matter, living matter, has to resolve in each and every one of its moments of existance. The environment of a living being is apart of the living being where it turns out, the rest of the living beings live. This is the drama of life on earth. Every living individual debates with his environment, exchanging matter, energy and information in the hope of staying alive, the same as all living beings who share that same environment. The adven­ ture of a living being (of all living beings ) is to maintain reasonable independ­ ence in face of the fluctuations ofuncertainty within the environment. The range of restrictions and mutual relationships is colossal. How is the tran­ seendental pretension of staying alive regulated? There is an equation imposed by the laws of thermodynamics and the mathematical theory ofinformation about the interaction ofa living being with his environment which we could state like this: The complexity 01 a living individual plus his capacity for anticipation in re­ spect to his environment is identical to the uncertainty of the environmentplus the capacity of that living being to change the environment.
