The Bell inequalities can be discussed on three levels: by means of classical probabilities, with classical conditional probabilities, and with quantum probabilities. In the talk I will demonstrate that the violation of the Bell inequalities have a clear meaning on the first two levels: on the first, it rules out the probabilistic interőretation of certain events, and on the second, it rules out the a common cause type interpretation of the correlation of such events. But the interpretation of the Bell inequalities applied in the context of field theories is not so obvious.
