Let's think first the following argument: if (1) classical mechanics implies Laplacian determinism, and (2) biology is reducible in principle to classical mechanics, then Laplacian determinism holds in biology and therefore, probability used in biology is only the result of classical ignorance. This claim seems to represent the so-called classical attitude toward the probability concept, but still there are many advocates of this position. I will show that this position is wrong by investigating the argument of Laplace's demon. It is shown that probability model can't be reduced to mechanical model, because of having different points of view. We will see the concrete differences between two types of models. From the construction of each model, I will claim that the difference between two types of models is due to the point of view of thinking of the world. Models include many points of view and among them the elements of agents are implicitly included in (genetic) probability models, whereas there are fewer elements in mechanical models than probability models.
