ABSTRACT
The world is indeterministic if some actual event might have failed to occur without violation of any actual laws; likewise, it is indeterministic if some event that did not in fact occur might have occurred without violation of any laws. One might also make the point in terms of chance: in a deterministic world the chance of an event's occurring, given the prior history of the world, is either 0 or 1, whereas in an indeterministic world the chance may be strictly between 0 and 1.
