According to determinism, the state of the world long before you were born, a world you never made, determines everything that happens. In one very weak version of indeterminism, its incompatibility with determinism is simple contradiction . This view is true so long as somewhere in the universe some occurrence violates the thesis of determinism. By way of maximum contrast, an extremely strong version of indeterminism is strongly contrary rather than merely contradictory to determinism. The world at any time and in all its aspects is totally independent of its state at any earlier time.
Successive events are never causally related in any way.
This form of indeterminism appears to be incompatible with the existence of successive events. Between these extremely strong and weak versions of indeterminism, views of intermediate strength hold that there are many events, widely scattered in space and time, that violate determinism. These events need not be totally independent of earlier states of the world. Determination and indetermination admit of degrees. The state of the world ten minutes ago may, for example, be causally sufficient for your now being somewhere in the general vicinity without exactly determining your current location.
