Wherefore we find, that to learn these things whereof we imbibe nor the images by our senses, but perceive within by themselves, without images, as they are, is nothing else, but by conception, to receive, and by marking to take heed that those things which the memory did before contain at random and unarranged, be laid up at hand as it were in that same memory where before they lay unknown, scattered and neglected, and so readily occur to the mind familiarised to them. And how many things of this kind does my memory bear which have been already found out, and as I said, placed as it were at hand, which we are said to have learned and come to know which were I for some short space of time to cease to call to mind, they are again so buried, and glide back, as it were, into the deeper recesses, that they must again, as if new, he thought out thence, for other abode they have none: but they must be drawn together again, that they may be known; that is to say, they must as it were be collected together from their dispersion: whence the word "cogitation" is derived. For cogo (collect) and cogito (re-collect) have the same relation to each other as ago and agito, facio and factito. But the mind hath appropriated to itself this word (cogitation), so that, not what is "collected" any how, but what is "recollected," i.e., brought together, in the mind, is properly said to be cogitated, or thought upon.
