11.27.36   It is in thee, my mind, that I measure times. Interrupt me not, that is, interrupt not thyself with the tumults of thy impressions. In thee I measure times; the impression, which things as they pass by cause in thee, remains even when they are gone; this it is which still present, I measure, not the things which pass by to make this impression. This I measure, when I measure times. Either then this is time, or I do not measure times. What when we measure silence, and say that this silence hath held as long time as did that voice? do we not stretch out our thought to the measure of a voice, as if it sounded, that so we may be able to report of the intervals of silence in a given space of time? For though both voice and tongue be still, yet in thought we go over poems, and verses, and any other discourse, or dimensions of motions, and report as to the spaces of times, how much this is in respect of that, no otherwise than if vocally we did pronounce them. If a man would utter a lengthened sound, and had settled in thought how long it should be, he hath in silence already gone through a space of time, and committing it to memory, begins to utter that speech, which sounds on, until it be brought unto the end proposed. Yea it hath sounded, and will sound; for so much of it as is finished, hath sounded already, and the rest will sound. And thus passeth it on, until the present intent conveys over the future into the past; the past increasing by the diminution of the future, until by the consumption of the future, all is past.
