The World Of Sensation

The reports of our sense organs are called "sensations." A sensation is

defined as "an impression, or the consciousness of an impression, made

upon the mind through the medium of a nerve or one of the organs of

sense. The term 'sense' is defined as 'a faculty possessed by animals of

perceiving external objects by means of impressions made upon certain

organs of the body, or of perceiving changes in the condition of the

body.' Our senses have been well said to constitute 'the doors to the

outside world.' Unless our attention is specially directed to the

subject, few of us even begin to realize how completely we are dependent

upon these 'doors' to the outside world" for our knowledge of that

outside world. It is only when we stop to imagine how completely shut

in, or shut out, we would be if all of our sense channels should be

destroyed, that we can even begin to realize just how dependent we are

upon our senses for our knowledge of the world in which we live, and

move, and have our being.
