But higher in the personal life than unconsciousness, higher than the reflex instincts, are the conscious experiences. By these, we for the first time became aware of what is going on within us and without. Messages sent from the outer world are stopped at a central office established in consciousness, looked over, and deciphered. We judge whether they require to be sent in one direction or another, or whether we may not rest in their simple cognizance. Every moment we receive a multitude of such messages. They are not always called for, but they come of themselves. My hand carelessly falling on the table reports in terms of touch. A person near me laughs, and I must hear. I see the flowers on the table; smell reports them too; while taste declares their leaves to be bitter and pungent. All this time the inner organs, with the processes of breathing, blood circulation, and nervous action, are announcing their acute or massive experiences. Continually, and not by our own choice, our minds are affected by the transactions around. Sensations occur—
"The eye, it cannot choose but see;
We cannot bid the ear be still;
Our bodies feel, where'er they be,
Against or with our will."
These itemized experiences thus pouring in upon our passive selves are found to vary endlessly also in degree, time, and locality. Through such variations indeed they become itemized. "Therefore is space and therefore time," says Emerson, "that men may know that things are not huddled and lumped, but sundered and divisible."
