ABSTRACT
Even the simple act which we describe as ‘seeing someone we know’ is, to some extent, an intellectual process. We pack the physical outline of the creature we see with all the ideas we already formed about him, and in the complete picture of him which we compose in our minds those ideas have certainly the principal place. In the end they come to fill out so completely the curve of his cheeks, to follow so exactly the line of his nose, they blend so harmoniously in the sound of his voice that these seem to be no more than a transparent envelope, so that each time we see the face or hear the voice it is our own ideas of him which we recognize and to which we listen.
