Every axiomatic (abstract) theory admits, as is well known, an unlimited
number of *concrete* interpretations besides those from which it was
derived. Thus we find applications in fields of science which have no
relation to the concepts of random event and of probability in the precise
meaning of these words.

---A.N. Kolmogorov
