This has been called the Law of Uni to experience. It was, however, largely Hume's versal Causation, and may be expressed by doctrine of causality that led to Kant's new point saying that the explanation of every event is of view, and to the doctrine that experience is the to be found in antecedent conditions. Scientific product of the understanding, the realisation of its investigation also presupposes the Law of the a priori forms. It is not the sequence of events in Uniformity of Nature, that the same conditions time, Kant holds, that gives rise to the principle of or cause will be followed (at all times and places) causality ; but the pure notion of causality finds by the same effects. The grounds and mutual its realisation in this time-sequence, in which each relation of these two assumptions form the chief event is determined by its antecedent.
