There is scarce a moment of my life, wherein there is not a similar instance presented to me, and I have not occasion to suppose the continued existence of objects, in order to connect their past and present appearances, and give them such an union with each other, as I have found by experience to be suitable to their particular natures and circumstances. Opposed to this is empirical knowledge, or that which is possible only a posteriori, that is, through experience. For they have, in truth, no relation to any object, in experience, for the very reason that they are only ideas.
