THIRD AND LAST LAW OF MEMORY.

=Good Princess.= } In. & Con.

=Pocahontas.= }

A proper name as such has little meaning. It is usually a mere _sound_

to which the person that bears it answers as the dog responds to the

name "Carlo." It is a sound which we call a name, and which we apply to

one person to distinguish that person from all others, as in this case

Pocahontas is used to distinguish the daughter of Powhattan from all

other Indian women. She knew who was meant when that name was applied to

her. But the name Pocahontas does not indicate that she was wise or

unwise, learned or unlearned, tall or short, old or young. In saving the

life of Capt. John Smith she became entitled to be called a "_Good_

Princess." In this case it would be In. by G. & S. We have heard of all

this, and now when we think of Pocahontas, we are apt to remember that

she was a good Princess for saving Smith's life. The connection between

these words I call Concurrence. We have thought of these words together,

and the mind by its own operation has cemented them together, so that

when we think of one it is apt to make us remember the other.

_Concurrence means that which has been accidentally, or as cause and

effect, conjoined in our experience._ Between the words or ideas thus

conjoined, there is, strictly speaking, neither Inclusion or Exclusion.

Whenever there are unrelated things which the mind holds together simply

because it has occupied itself with them, then we have a case of

concurrence to be represented by Con. Other examples: "Harrison,

Tippecanoe;" "Columbus, America;" "Washington, Cherry Tree;" "Andrew

Jackson, To the Victors belong the Spoils;" "Newton, Gravitation;"

"Garfield, Guiteau;" "Gladstone, Home Rule," &c.

=Pocahontas.= } Con.

=Capt. John Smith.= }

We have read the story of the rescue of Smith by Pocahontas. We have

_thought of these names together_ and they have united in our memories

by the Law of Concurrence. When we recall the name of Pocahontas, we are

apt to revive also the name of Capt. John Smith and _vice versa_.

Another case:--A gentleman was present at Ford's Theatre in Washington

when John Wilkes Booth shot Abraham Lincoln. Just a moment before, he

recognised the odour of a hyacinth held by a lady in front of him. The

next moment he heard the fatal shot, and turning whence the report came,

he saw the murderous result. After the lapse of a quarter of a century,

he could not smell, see, or think of hyacinth without at once thinking

of that scene, nor could Lincoln's assassination be mentioned in his

presence without his instantly thinking of hyacinth. Nothing could have

been more purely _accidental_ than the quick succession of the sensation

of the odour and the murder of the President. But they were _experienced

together_ or nearly together. They became cemented together, so that the

revival of one is apt to call up the other, and this is concurrence.

=Capt. John Smith.= } Con.

=Anvil.= }

A proper name may be also used in other relations. The word, sound, or

name Smith may also be a general term applicable to many classes of

persons, as _coppersmith_, _goldsmith_, _silversmith_, &c. When we think

of _Capt. John_ Smith we use the word as a proper name. But when we

think of Smith and Anvil we use the word Smith in its general sense. In

either case it is an act of Concurrence. Smiths use anvils. We have

thought of these words together, and that mental act has had a tendency

to unite them together.

=Anvil.= } In. by A. & C.

=Heavy.= }

Anvil is a _concrete thing_ that possesses the attribute heaviness; and

heavy is an abstract term that applies to heavy things, but does not

state what they are. The idea or thought of heaviness is _common_ to

both words, and therefore it is a case of In., and as one term is

concrete and the other abstract, it is a case of In. by A. & C.

=Heavy.= } Con.

=Gravitation.= }

Things are heavy that press toward the earth, in consequence of the

action of gravity in their case. Gravitation, whatever that is, is what

makes them tend toward the earth. We may say it is a Cause, and as we

think of Cause producing Effect, and Effect as produced by Cause, such

cases are _thought of together_, or almost simultaneously, and hence we

have a case of Concurrence.

=Gravitation.= } Con.

=Sir Isaac Newton.= }

There is no In. or Ex. here, but Con. We have read or heard that Newton

discovered the Law of Gravitation. We have exercised our minds in regard

to these two words, in thinking of them together, and that is

concurrence.

=Sir Isaac Newton.= } Con.

="Diamond."= }

Newton went out of his library on one occasion, leaving his pet dog

"Diamond" in the room. The dog jumped up on to the table, overturned the

light, which set fire to most valuable manuscripts. They burned up. When

Newton returned and discovered what his pet had done, he exclaimed, "O!

Diamond, Diamond, thou little knowest what thou hast done." The name

Diamond becomes thus vividly associated in our minds with the

forbearance of the great Newton. We cannot forget it. We hold them

together hereafter by Con.

=Diamond.= } In. by s.

=Dying.= }

A plain case of Inclusion by sound.

=Dying.= } Con.

=Cholera.= }

We know that cholera _causes_ numerous deaths; that people die in great

numbers wherever it prevails.

=Cholera.= } Con.

=Terror.= }

Concurrence includes all cases of Cause and Effect, Instrument or Means

to End, Person by whom or Thing by which, &c. Cholera causes terror.

Terror is the _effect_ of the existence of the cholera. Now carefully

read over the eleven words just considered, and think out the relations

between them.

Good Princess.

Pocahontas.

Capt. John Smith.

Anvil.

Heavy.

Gravitation.

Sir Isaac Newton.

"Diamond."

Dying.

Cholera.

Terror.

Now recite them from memory at least five times forward and backward,

and then recite the entire thirty words from Building to Terror, and

from Terror to Building, the same number of times.

For further training, let each pupil recite the foregoing series of

thirty words forward and backward two or three times per day for an

entire month. He need not stop further study, but whatever else he

learns let him at least practise this daily recital for one month.
