Abstract

The primitive conception is that the future already exists like a terra incognita which one can dimly make out with or without the help of the gods. This idea is at the basis of fatalism and of belief in prophets, oracles and astrologers. This ancient concept was replaced in the nineteenth century by the vocabulary of scientific determinism which said that actual beings can only function. If one knew in detail their structures and their movements, one could calculate the results of their functioning with perfect precision.
