Thus, the relation of phenomena (as possible perceptions), according to which that which happens is, as to its existence, necessarily determined in time by something which antecedes, in conformity with a rule--in other words, the relation of cause and effect--is the condition of the objective validity of our empirical judgements in regard to the sequence of perceptions, consequently of their empirical truth, and therefore of experience. I shall only infer from them, that since reason can never give rise to the idea of efficacy, that idea must be derived from experience, and from some particular instances of this efficacy, which make their passage into the mind by the common channels of sensation or reflection. Thus, when I say that certain events occurred in past time, I merely assert the possibility of prolonging the chain of experience, from the present perception, upwards to the conditions that determine it according to time. Now I cannot obtain the least representation of a thinking being by means of external experience, but solely through self-consciousness. In both these cases the principle of causality, which is valid only in the field of experience--useless and even meaningless beyond this region, would be diverted from its proper destination. But in this case it is not an object of possible experience.
