What is the Second Stage of the Memory? This moment you recall what? Not the procession itself; for it is no longer in existence. You saw and heard it then, but you do not see or hear it now. You only recall the impression left upon your mind by the procession. A ray of Consciousness is passed over that impression and you re-read it, you re-awaken the record. This is the Second Stage of the Memory--the _revival_ of the previous experience--the recall to consciousness of the First Impression. The First Impression with no power to revive it afterward, gives no memory. However great the power of Revival, there is no memory unless there was a First Impression. There are three conditions of memory--(1) Impression. (2) Its Preservation. (3) Its Revival. We are mainly concerned here with the Impression and its Revival. There are (_five_) kinds of memories rising from the natural aptitudes of different individuals--(1) First Impressions are apt to be feeble and the power to revive them weak--a poor memory. (2) First Impressions are usually weak but the power to revive them is strong--still a poor memory. (3) First Impressions are usually vivid but the power to revive them is weak--a poor memory. (4) First Impressions on all subjects are strong and the power to revive them is strong--a first-class memory. (5) First Impressions in some particulars are very strong and the reviving power in regard to them is very strong--a good memory for these particulars, or a memory good for mathematics, or music, or faces, or reciting, or languages, &c., but usually weak in most other respects. SINCE WE ARE TO LEARN BY THINKING WE MUST AT THE OUTSET LEARN THE DEFINITION OF THE THREE LAWS OF THINKING. THREE LAWS OF MEMORY OR OF THINKING. _The first and principal thing the pupil requires to do in this lesson after learning the definition of the following Three Laws--is to be able to clearly understand the examples under each Law, and whether they verify or illustrate that Law._ I. INCLUSION indicates that there is an _overlapping_ of _meaning_ between two words, or that there is a _prominent idea_ or _sound_ that belongs to both alike, or that a similar fact or property belongs to two events or things as, to enumerate a few classes:-- WHOLE AND PART.--(Earth, Poles.)
