If then it be admitted as a necessary law of sensibility, and consequently a formal condition of all perception, that the preceding necessarily determines the succeeding time (inasmuch as I cannot arrive at the succeeding except through the preceding), it must likewise be an indispensable law of empirical representation of the series of time that the phenomena of the past determine all phenomena in the succeeding time, and that the latter, as events, cannot take place, except in so far as the former determine their existence in time, that is to say, establish it according to a rule. The natural consequence of this reasoning should be, that our perceptions have no more a continued than an independent existence; and indeed philosophers have so far run into this opinion, that they change their system, and distinguish, (as we shall do for the future) betwixt perceptions and objects, of which the former are supposed to be interrupted, and perishing, and different at every different return; the latter to be uninterrupted, and to preserve a continued existence and identity. It is evident I can never account for this phenomenon, conformable to my experience in other instances, without spreading out in my mind the whole sea and continent between us, and supposing the effects and continued existence of posts and ferries, according to my Memory and observation. For the existence of phenomena, always conditioned and never self-subsistent, requires us to look for an object different from phenomena--an intelligible object, with which all contingency must cease. We may, therefore, conclude with certainty, that the opinion of a continued and of a distinct existence never arises from the senses. It is this principle, which makes us reason from causes and effects; and it is the same principle, which convinces us of the continued existence of external objects, when absent from the senses. [*Footnote; As to the existence of pure natural science, or physics, perhaps many may still express doubts.
