Perceive >>> Feel >>> Remember
We depend first of all upon our observation in forming judgments, or more strictly speaking, upon the perceptions of our senses—hearing, touch, smell, taste, as well as sight; the accumulation and repetition of these sense perceptions and of our interpretation of them becomes what we may call experience; and the power that stores them up in our mind we term memory. "Seeing is Believing," but it is a notorious fact that our eyes can easily lead us astray. How often, too, is it found that reliable eyewitnesses may give substantially different accounts of the same simple occurrence! Why is this?
It is possible to see things, without noticing or being aware of them. The eye registers an impression of everything that comes within the range of its view; but our awareness depends upon a number of circumstances; our attention may be weak, or intermittent, or distracted; we may be preoccupied; we may be in poor bodily health. Again, the direction of our attention is naturally determined by our interests at the time or by our point of view.
