The reason which persuades me that the soul can have no other place in the whole body but this kernel where she immediately exercises her* functions is for that I see: all the other parts of our brain are paired, as also we have two eyes two hands, two ears; lastly, all the organs of our exterior senses are double and forasmuch as we have but one very thing at one and the same time. It must necessarily be that there is some place where the two images that come from the two eyes, or the two other impressions that come from any single object through the double organs of the other senses, have somewhere to meet in one, before they come to the soul, that they may not represent two objects instead of one. And it may be easily conceived that these images, or other impressions, join to hither in this kernel by intercourse of the spirits that fill the cavities of the brain, but there is no other place in the body where they can be so united, unless it be granted that they are in this kernel.
