20. Behold, the present time, which alone we found could be called long, is abridged to the space scarcely of one day. But let us discuss even that, for there is not one day present as a whole. For it is made up of four-and-twenty hours of night and day, whereof the first has the rest future, the last has them past, but any one of the intervening has those before it past, those after it future. And that one hour passes away in fleeting particles. Whatever of it has flown away is past, whatever remains is future. If any portion of time be conceived which cannot now be divided into even the minutest particles of moments, this only is that which may be called present; which, however, flies so rapidly from future to past, that it cannot be extended by any delay. For if it be extended, it is divided into the past and future; but the present has no space. Where, therefore, is the time which we may call long? Is it nature? Indeed we do not say, It is long, because it is not yet, so as to be long; but we say, It will be long. When, then, will it be? For if even then, since as yet it is future, it will not be long, because what may be long is not as yet; but it shall be long, when from the future, which as yet is not, it shall already have begun to be, and will have become present, so that there could be that which may be long; then does the present time cry out in the words above that it cannot be long.
