Objects of representations and Kant's Second Analogy

Kant's Second Analogy attempts to prove a causal principle, which is best interpreted as arguing that successions of appearances or events cannot be objects of experience or objects of representations unless they occur according to a rule. The Second Analogy does not present Kant's complete theory of causation, but includes only those aspects needed to make experience possible, those that come under the transcendental proof. Therefore, requirements for repeatability and necessary order are not included in the causal principle of the Second Analogy.
