Chapter 2: Thought and Its Operation

=1. THE KNOWING MIND COMPARED WITH THE THINKING MIND.=

In the preceding chapter we were told that the mind may know in two ways (1) by intuition and (2) by thinking. It is thus implied that the knowing mind includes the thinking mind plus intuition. Thinking always involves knowing, but knowing need not involve thinking, and when some logicians maintain that to know a thing one must think it, there is danger of being misled. They mean by this that in order to know anything in a permanent and highly serviceable way one must think it. All animals know, even such a stupid one as the oyster, and yet one would hardly give an oyster credit for thinking. Only the higher orders of animal life think. Some argue that the power is confined exclusively to the human family. This opinion is debatable. If the claimant means by thinking, reasoning then his ground is well taken. But if he is willing to give to thinking a broader content, then he has little defense for his stand. However, attach as broad a meaning to thinking as the derivation of the word will permit and even then it is a narrower term than knowing. Thinking plus intuition equals knowing, and in intuition there is probably no thinking.

=2. KNOWING BY INTUITION.=

It has been affirmed that intuition is the process involved when the mind knows _instantly_.[2]

ILLUSTRATIONS:

(1) As I raise my eyes a figure comes to view. My mind knows _instantly_ that it is the figure three. (2) The ear catches _immediately_ a tune which is being sung in the room below. Without deliberation the mind recognizes the tune as America. The mind may thus know by intuition through any one of the five senses. These are the wires of connection between the outer world and the mind within and transmission over these wires may be instantaneous or intuitive. This is not all. (3) My mind may center its attention on itself and may recognize there a mental picture or image of a pet dog. Since this activity is without any apparent deliberation the process must be intuitive. To define intuitive knowledge as that which comes to the mind through the senses only is incorrect, as it leaves out altogether the knowledge the mind may obtain of its own activity as in illustration “(3).”

Knowledge is anything known. _Intuitive knowledge is knowledge which comes to the mind immediately by direct observation._ The field for intuitive knowledge may be the external world or the internal world though, of course, the former is the more common ground. It is here that the mind by intuition secures the most of its raw material which, through the process of thinking, is worked over into a connected, unified system of lasting value.

The intuitions are the beginning and the basis of all knowledge, and knowledge gained by intuition is the basis of all thinking.

=3. THE THINKING PROCESS.=

It is claimed that _think_ comes from the same root as _thick_. From this one would conclude that the process of thinking is virtually a process of thickening. Surely as one thinks he enriches or thickens his knowledge. As one thinks percepts into concepts and concepts into judgments he makes richer in meaning the various notions concerned. Thinking is largely a matter of pressing many into one: of linking together the disconnected fragments of the conscious field.

DEFINITION:

_Thinking is the deliberative process of affirming or denying connections._

The same idea may be expressed in a variety of ways as the following indicate.

(1) “Thinking is the conscious adjustment of a means to an end in
problematic situations.” Miller.

(2) “To think is to designate an object through a mark or attribute
or what is the same thing, to determine a subject through a
predicate.” Bowen.

(3) “Thought is the comprehension of a thing under a general notion
or attribute.” Wm. Hamilton.

(4) “To think is to make clear through concepts the perceived
objects.” Dressler.

In the foregoing definitions it is implied that thinking is a connecting or _thickening_ process. In all forms of thinking from the simplest to the most complex the knowing mind hunts for some basis of connection and having found it _thinks_ the relationship into a unified whole.

The thinking process is the digestive process of the mind. Much as the digestive organs assimilate the food stuff of the physical world, so the thinking organ assimilates the food stuff of the mental world.

ILLUSTRATIONS OF THE THINKING PROCESS:

(1) The child is unable to explain the meaning of “hocus-pocus” as it occurs in the question, “What hocus-pocus is this?” The child mind is unable to establish any connection between the word and its real meaning. In short, is unable to _think into it a meaning_; it therefore becomes necessary for the teacher to establish some basis of connection and this he does by suggesting _nonsense_ as a _synonym_.

(2) The teacher holds before the class an Egyptian house god and asks, “What is it?” After a moment of hesitation some child who has seen pictures of “his satanic majesty” avers that the object is a “little devil.” Thus has a connection been established between the idol and pictures of satan.

(3) John is unable to solve the following problem as he can discern no connection between the data given and the data required. Problem. 3/4 of my salary is $900, what is my salary?

Data. Given: 3/4 of salary = $900.
Required: 4/4 of salary = ?

In order that John may _think_ a solution the teacher must lead him to see some connection between 3/4 and 4/4. With this in mind the form of the data is changed to

Given: 3-fourths = $900
Required: 4-fourths = ?

or

Given: 3 parts = $900
Required: 4 parts = ?

John now notes that 4 parts is 4/3 times 3 parts and consequently writes 4/3 of $900, which is $1,200 as the answer. Or he may find the value of 1 part and then of 4 parts.

=4. NOTIONS, INDIVIDUAL AND GENERAL.=

_A notion is any product of the knowing mind――anything which the mind notes or becomes aware of._

But the mind knows in two ways, by intuition and by thinking. In consequence the mind has two kinds of notions, those which are intuitive or _individual notions_ and those which originally result from thinking or _general notions_.

_An individual notion is a notion of one thing. A general notion is a notion of a class of things._

_Note._ Here it is necessary to distinguish between a thing and an object. _An object is a thing which occupies space_ such as a pencil or a book. “_Thing_” is, therefore, a broader term than “_object_.” “_A thing is that which has individual existence._” From the viewpoint of logic “thing” includes objects, qualities, relations, spiritual entities. Gravitation is a thing but not an object. A tree is both an object and a thing.

ILLUSTRATIONS OF NOTIONS.

My notion of the pencil with which I am writing is an individual notion, but my notion of pencil as a _class name_ is general. My yellow dog, the honesty of Lincoln, Albert White, New York City, are individual notions, while dog, honesty, man, city, are general notions.

A sure way to determine whether the notion is individual or general is to attempt to divide it into its kinds. Only general notions may be subdivided.

=5. KNOWLEDGE AND IDEA AS RELATED TO THE NOTION.=

Knowledge is anything known, while anything of which the mind becomes aware is a notion. Notions are always bits of knowledge, but knowledge is not always a notion. Notions are mental products belonging to the mind which thinks them, while knowledge, though it must first be a mental product of someone’s mind, may not necessarily be a product of yours or mine. Notions are always found in the mind, while knowledge may be found in books, but not necessarily in some individual mind. Knowledge stands for everything _known_, the notion, for everything _noted_. The Egyptians may have possessed much knowledge of which we may never become aware. Much of their _knowledge_ may never become _notions_ of the American people. A notion is an existing state of consciousness. Said notion may be committed to paper, and then it may give way to another notion. It now ceases to be your notion, but remains on the printed page, as a bit of knowledge.

“Idea,” because of its ambiguity, really has no place in logic. The term is frequently restricted to a _reproduced percept_. To illustrate: When the pencil is before me the mental product is a percept, but when the pencil is withdrawn and I try to think of it, then have I an _idea_ of “pencil.” Probably _idea_ is most commonly associated with _meaning_ and _belief_. To illustrate: What is your _idea_ as to the meaning of homogeny? or What are your _ideas_ on the tariff?

=6. THE LOGIC OF THE PSYCHOLOGICAL TERMS INVOLVED IN THE NOTION.=

Concerning the knowing mind the psychologist classifies its activities and their products as follows:

_Activity_ _Product_
(1) Presentative
(1) Sensation Sensation
(2) Perception Percept

(2) Representative
(1) Imagination } Image
(2) Memory }

(3) Thinking
(1) Conception Concept
(2) Judging Judgment
(3) Reasoning Inference

The notion as _any_ product of the knowing mind includes the _six_ products as indicated by the psychologist.

The individual notion which is intuitive includes the sensation, percept and image; the general notion which is a thought product stands for the concept, judgment and inference. To put it mathematically――

{ sensation } }
Individual notion = { percept } = intuitive products }
{ image } } _notion_
{ concept } }
General notion = { judgment } = thought products }
{ inference } }

As we shall have occasion frequently to refer to these psychological terms it may be well to define them.

judgments.

It is seen that the sensations furnish the raw material. Ignoring the few exceptions we may then say that a percept is a made-over group of sensations; a concept a thought-made group of percepts; a judgment a thought-made group of concepts; an inference a judgment derived from other judgments.

_Developed thinking_ is first found in the concept, and as we study the thought products, “concept,” “judgment” and “inference,” the truth is forced upon us that _thinking as a process aims to group the many into one_. From many percepts is built the one concept, from two concepts is built the one judgment and from two judgments is built the one inference.[3]

Speaking figuratively, thinking is a matter of picking up the fragments along the shore of consciousness and tying them into bundles.

=7. THOUGHT IN THE SENSATION AND PERCEPT.=

So far in this discussion it has been assumed that there is
no thinking involved in the sensation or the percept. There
are good authorities, however, who insist on dignifying the
sensation, even with a crude form of thinking. To illustrate:
One may be reading an interesting novel. The mind is being
entertained and ignores the activities of the objective world,
yet we cannot say that the mind is dead to the world outside.
There is a dim consciousness of certain noises without. These
unlocalized sounds are sensations; but how is the mind able to
recognize them as sounds or noises? To interpret the noises is
it not necessary for the mind to affirm a connection between
them and some past mental experience? Is it possible for
the mind to know anything without establishing some kind
of connection between the outside occurrence and an inner
situation? If this is granted then in sensation there must be
implicit thinking.

As the percept is a localized group of sensations then
there must be involved in perception a more complex form of
thinking, since in grouping sensations there is a recognition
of connections.

If there is thinking in the sensation which is the simplest and
lowest form of the knowing-mind then thinking conditions all
knowledge and really is the basic elemental cell of all knowing.

On the other hand there are those who maintain that the
sensation and percept are mere reflections of consciousness; the
sensation being a reflected quality and the percept a reflected
object. These mental situations come into being instantly――there
is no time for thought and we all know that thought requires
time. (“As quick as thought” is misleading, since light travels
more rapidly by many times than the agencies of thought.)

It will probably never be settled to the satisfaction of all
just when thinking commences. The question is as difficult
as some others which have never been solved. For example:
Where does life commence? When does the plant merge into the
animal? Which was first the egg or the hen? Does the objective
world really exist or is it only a mental interpretation of
vibrations? etc.

Logically considered the question is immaterial. All will agree
that developed thought is involved in the concept, judgment
and inference, while, if it appears at all in the percept and
sensation, it is more or less undeveloped and consequently lies
quite without the province of the logical field.

=8. EVOLUTION AND THE THINKING MIND.=

Speaking in general terms evolution is a development from a lower to a higher state. Thus have come the various species of the vegetable and animal world. The lower orders of life are simple in structure and function. In the one-celled animate form a single organ performs all of the work needed to maintain life and perpetuate the species. If these simple life-forms are cut in two, life continues in the two parts as if nothing had happened. Aside from their simplicity there is little of interdependence of function and little of co-ordination of organs in the lowest life-forms. In short there is no division of labor; “each cell is a world unto itself.”

An analogous development is seen in the thinking mind. The little child thinks in _lumps_, and these lumps are only faultily linked together, but the adult thinks in terms of the _grains_ of the lump, each grain having its place, which it must occupy for the sake of all the other grains as well as the entire lump. The child’s thinking is vague, general and inaccurate, while the adult’s thinking should be definite, specialized and accurate. Thinking in the lump means little discrimination and very faulty integration or unity, while thinking in terms of the grains means detailed discrimination and perfect integration. To illustrate: The child sees a dog trotting along the side walk which, according to the suggestion of his mother, he learns to call “bow-wow.” Later he observes a cat and at once says “bow-wow,” because all that the child notes is that something with legs, ears and a tail is trotting along the side walk. Anything which fits these general marks is a “bow-wow.” Similarly when a child first observes a robin perched on a gate post he fails to distinguish between the two――it is _all_ bird from the top of the robin’s head to the bottom of the gate post.

Progress in thinking is measured by progress in discrimination. The skilled thinker divides the large unit into very small units, compares these with each other and then reunites them into a more perfect and unified whole. First there is an analysis and then a synthesis. Like a shuttle the power of thought works in and out; it goes in to separate, it comes out to unify.

There is another aspect in the analogy between the life of the physical and mental worlds. Somewhere in the order of progress there is a connecting link between the mineral and vegetable kingdoms, likewise between the vegetable and animal kingdoms. The sensation is as much a state of feeling as an act of knowing and consequently is the connecting link between the _feeling_ mind and the _knowing_ mind. If the percept is the result of thinking as well as intuition then it may stand for the dividing line between the _knowing_[4] mind and the _thinking_ mind.

=9. THE CONCEPT AS A THOUGHT PRODUCT.=

_Conception is the process of thinking many notions into one
class._ The product of such a process is called a concept.
(1) The concept may stand for a group of concrete _general_
notions――as the concept _man_, which stands for the five general
notions: Caucasian, Mongolian, Ethiopian, Malay and American
Indian. (2) The concept may stand for a group of concrete
_individual_ notions. For example, the same concept _man_
represents all of the individual men of the world. (3) The
concept may stand for a group of _abstract general_ notions. To
wit: Virtue represents such general notions as honesty, justice,
industry, purity, etc. (These are general notions because they
admit of a subdivision into kinds. Industry, for instance,
may be divided into two kinds: mental industry and physical
industry.) (4) The concept may stand for a group of _abstract
individual_ notions. To illustrate: Blueness stands for the
various shades of blue, as sky blue, bird’s egg blue, navy blue,
etc.

Thus does the concept stand for a group of all kinds of notions,
individual and general, abstract and concrete.

THE PROCESS OF CONCEPTION ILLUSTRATED.

I see for the first time in my life a pencil. In other words I
become conscious of a localized group of sensations――this is a
percept. I am told that the name of that which I see is _pencil_.
I note that this particular pencil has a thread of black lead
encased in a cylindrical strip of wood which is brown in color.
A second object is presented which I recognize as a pencil
though the shape is prismatic rather than cylindrical and the
color green rather than brown. But I call it a pencil because
it has a thread of black lead encased in a strip of wood. The
notion which I now have in mind stands for two pencils and
is therefore represented by a class name. As I observe other
pencils of various shapes, made of wood and paper with threads
of different colored lead, my notion of pencil broadens till
finally it stands for all pencils. This is the process of
conception according to the definition, namely: “The process of
thinking many notions into one class.” In this case the notions
are individual.

An examination of conception makes evident two distinct
characteristics. First, I may be able to recognize each
individual pencil because of the two common qualities, a
thread of lead and an encasement of some kind. This process of
the knowing mind whereby it recognizes and affirms connections
is called thinking as we have already learned. Here is the
_thinking_ aspect of conception. Second, as the instances of
the observed objects are multiplied, my notion of pencil is
_broadened_. It is a building process where many are cemented
into one; like the blocks of a cement wall. Here we find the
characteristic which enables us to call the process _conception_.
This is the mark which distinguishes conception from all the
other thought processes.

=10. THE JUDGMENT AS A THOUGHT PRODUCT.=

Judging is the process of conjoining and disjoining notions.
The product of judging is the judgment and all judgments are
expressed by means of propositions. A proposition consists of
one subject and one predicate connected by some form of the verb
_be_ or its equivalent.

(1) A judgment may conjoin or disjoin two individual notions.
To wit: Conjoined――This pencil belongs to Albert White.
Disjoined――This pencil does not belong to Mary Smith.

(2) A judgment may conjoin or disjoin two general notions.
Conjoined――Some men are virtuous.
Disjoined――Some men are not virtuous.

(3) A judgment may conjoin or disjoin a general and an individual
notion.
Conjoined――Abraham Lincoln was virtuous.
Disjoined――Edgar Allen Poe was not temperate.

In order that the knowing mind may conjoin notions it must
recognize some mark of similarity or connection. This is the
_thinking_ aspect of the judgment. It is likewise to a certain
degree the judging aspect as the latter is simply a matter of
affirming or denying connections between notions. But thinking
is a broader term than judging. There may be connections
established between a name and a notion. For example in the case
of the dog which the child sees trotting along the sidewalk and
which the mother refers to as a “bow-wow”; the term “bow-wow” is
not a percept and has no meaning independent of its association
with the dog, hence it is not a notion, yet some connection has
been made in the child’s mind between “bow-wow” and his notion
of dog. This is a simple form of thinking, but not of judging,
as the latter affirms or denies connections between _notions_
only.

The fact that judging and thinking so closely resemble each
other has given just cause for some logicians to designate
judging as the most fundamental element in all thinking. “The
simplest form of thinking,” says Creighton, “is judging.” In
order to think many notions into one class it is necessary to
conjoin notions. To illustrate: The child who has a general
notion of man sees for the first time a negro. If he recognizes
the negro as a colored man he must conjoin his general notion of
man with this individual notion. In short, a concept is built by
means of a series of judgments. It may be said further that an
inference is simply a _made-over judgment_. It is thus evident
that judging appears in both the thought processes of conception
and inference and, therefore, as a final conclusion it may be
affirmed that judging, though perhaps not the simplest form of
thinking, is the basic element of _developed_ thought.

=11. INFERENCE AS A THOUGHT PRODUCT.=

Reasoning is the process of deriving a new judgment from a
consideration of other judgments. The product of any reasoning
process may be called an inference, although, as will appear in
a later chapter, inference is commonly used as indicating the
process as well as the product.

Often reasoning may assume a syllogistic form with the inference
as its conclusion. A syllogism is an arrangement of three
propositions using three different terms. The following are
syllogisms:

(1) All children should play.
Mary is a child.
Hence, Mary should play.

(2) No teacher should judge hastily.
You are a teacher.
Hence, you should not judge hastily.

In the second syllogism the inference, “you should not judge
hastily,” is derived from the other two judgments by merely
eliminating the common term teacher and disjoining the remaining
two terms. The inference is consequently a _new_ judgment.
Therefore, reasoning is only a matter of judging carried to a
more complex stage.

To summarize――_conception_ is largely a matter of conjoining
a general notion with an individual notion, _judging_ of
conjoining and disjoining all kinds of notions and _inference_
of conjoining and disjoining judgments. All three processes
go to form the larger process of thinking. _The concept, the
judgment and the inference are products arising from conjoining
and disjoining notions._

=12. THINKING AND APPREHENSION.=

Says Jevons: “Simple apprehension is the act of the mind by which we merely become aware of something, or have an idea or impression of it brought into the mind;” while Hyslop states that “The process of knowledge which gives us percepts is apprehension.” It is obvious that the idea of the latter is that _apprehension_ yields individual notions only, while Jevons, in citing the term _iron_ as an illustration of his definition, would infer that the general notion is the product of _apprehension_. The term is strikingly ambiguous and will not be referred to often in this treatise. If the student desires a definition this will cover the concensus of opinion on the meaning of apprehension. _Apprehension is that process of the knowing mind which yields the percept and concept._ Some logicians give to the thinking mind the three aspects of apprehension, judging and reasoning.

=13. STAGES IN THINKING.=

In all thinking there are three steps or stages which may be termed _discrimination_, _comparison_, _integration_.

In the case of the two pencils held in the hand, it is noted that one is longer than the other. Let us analyze the process which made possible this conclusion. Step one――Attention is given first to one pencil and then to the other. In each case the pencils are distinguished from the hand and the other surrounding objects. This is discrimination. Step two――The pencils are _compared_ in length. Step three――The two notions are united in the judgment, “Pencil number _one_ is longer than pencil number _two_.” This is integration.

Another illustration. The child is requested to solve this problem: If 8 tons of hay cost $165, what will 16 tons cost?

Statement: Given: 8 tons cost $165.
Required: 16 tons cost?

Discrimination. The child notes that 8 tons cost $165 and at this rate he is required to find the cost of 16 tons.

Comparison. The child perceives that 16 tons is twice 8 tons.

Integration. The child concludes that the cost of 16 tons will be twice the cost of 8 tons or $330.

When we think, we first tear to pieces that we may become acquainted with every part. This may be called analysis. Then we put the related pieces together again. This may be called synthesis. Before, however, the parts are re-united a certain amount of comparison is necessary. The three stages of thought might thus be denominated: (1) analysis, (2) comparison, (3) synthesis.

After the synthesis or integration it is necessary to name the result, consequently a fourth step is sometimes given, namely denomination.

=15. SUMMARY.=

(1) Knowing is a broader term than thinking as the former equals the latter plus intuition.

(2) Intuitive knowledge is that which comes to the mind immediately by direct observation.

Although intuitive knowledge comes to the mind without thought, yet such knowledge is _essential_ to all thinking. Intuitive knowledge is the foundation upon which the thinking mind builds.

(3) Thinking is the deliberative process of affirming and denying connections. Thinking is a “thickening process,” the smaller units being pressed together to make a larger. Thinking is chiefly a matter of reducing plurality to unity.

(4) A notion is any product of the knowing mind.

An individual notion is the notion of one thing.

A general notion is a notion of a class of things.

A thing includes objects, qualities, relations or any existing entity. A thing is that which has _individual existence_.

(5) A bit of knowledge must have been a notion of some one’s mind, but may not necessarily be a notion of _your_ mind. Knowledge may be found in books, but a notion is a mental product found only in the mind. Idea is ambiguous, though its meaning is usually restricted to an image, a meaning or a belief.

(6) The products of the knowing mind are the sensation, the image, percept, concept, judgment, inference.

The sensation, image and percept are individual notions, while the concept, judgment and inference are general notions.

A sensation is a vague, unlocalized product of the knowing mind.

A percept is a consciously localized group of sensations.

An image is a reproduced percept.

A concept is a mental product arising from thinking many notions into one class.

A judgment is a mental product arising from conjoining and disjoining notions.

An inference is a judgment derived from antecedent judgments.

The developed thought processes are the concept, the judgment and the inference.

(7) Just where the simplest form of thinking appears in the various activities of the knowing mind is still an undecided question. It is agreed that thinking in its developed and more complex form is found in conception, judging and reasoning.

(8) Thinking evolves from the simple to the more complex, just as life has evolved.

The child thinks in vague, indefinite wholes, while the adult thinks in clear, definite parts. The child discriminates very imperfectly while the adult discriminates accurately.

The sensation seems to be the connecting link between the feeling mind and the knowing mind, while the percept links together the knowing mind and the thinking mind.

(9) Conception is the process of thinking many notions into one class. The product of such a process is a concept. The concept stands for groups of all kinds of objects.

Conception has the two aspects of _affirming connections_ and of _building many into one_. The first is the thinking side of the process and the second is the mark which distinguishes conception from the other thought processes.

(10) Judging is the process of conjoining or disjoining notions. Judgment is the product of judging.

Judgments conjoin and disjoin all kinds of notions.

Judging and thinking, though they closely resemble each other, are not synonomous terms. Thinking is a broader term in that connections may be established between a notion and a name for that notion.

Judging is the most fundamental of all thinking, as the concept is built from a series of judgments and an inference is simply a made-over judgment.

(11) Inference.

Reasoning is the process of deriving a new judgment from a consideration of antecedent judgments. This derived judgment may be called an inference. Sometimes the term inference denotes the process of reasoning as well as the product.

Reasoning often takes the form of a syllogism.

The concept, the judgment and the inference are _products_ arising from conjoining and disjoining notions.

(12) Some give to the thinking mind the three aspects, apprehension, judging and reasoning. Apprehension is another word for the two processes, perception and conception.

(13) The three important stages in thinking are discrimination, comparison, integration; or analysis, comparison and synthesis.
