"And I enter the fields and spacious halls of memory, where are stored as treasures the countless images that have been brought into them from all manner of things by the senses. There, in the memory, is likewise stored what we cogitate, either by enlarging or reducing our perceptions, or by altering one way or another those things which the senses have made contact with; and everything else that has been entrusted to it and stored up in it, which oblivion has not yet swallowed up and buried." st. augustine on memory.
