THE FOUR PRINCIPLES OF LOGIC

Since this work wishes to demonstrate the positive outcome of

philosophy, the reader may ask the author what are his proofs that

instead of the quintessence of thousands of years of philosophical work

he is not offered the elaboration of any individual philosopher, or even

that of the author himself.

In reply I wish to say that my work would be rendered uselessly

voluminous by quotations from the works of the most prominent

philosophical writers, without proving anything, since the words of one

often contradict those of another.

What is said by Kant, Fichte, Schelling, or Hegel, in one place of any

of their works, is at least considerably modified, if not contradicted,

in another place of the same work. It is of little consequence, how and

by whose help I have arrived at the positive outcome of philosophy as

here rendered. Whether it is the actual outcome or not can be judged

only by the expert, and every opinion is necessarily very subjective.

Under the circumstances I, as author, claim that my opinion is worth as

much as any other, and the reader may therefore accept my assurance. As

to the further value of that which I offer, it is a peculiarity of the

subject under discussion that every reader carries it and its

experiences within himself and may, without consulting any other author,

at once draw his own conclusions about my views, provided he has

acquired the necessary training in thought. What a traveler tells us

about the interior of Africa must either be believed to the letter or

verified by the accounts of other travelers. But what I say about logic

will, I hope, find its corroboration in the logic of every reading

brain.

The theory of understanding which has become the special object of

philosophy, is nothing else, and cannot be anything else, but expanded

logic. Many practical rules and laws of this department are known and

recognized since the time of Aristotle. But the question whether there

is one world or two, a natural and unnatural, or supernatural as it is

called with preference, that is the point which has given much trouble

to philosophy and which will influence the health of logic so long as

it is undecided.

Dr. Friedrich Dittes, director of the institute of pedagogy in Vienna,

has published a _School of Pedagogy_, several editions of which have

appeared, in which he gives much attention to logic. Dittes is a

prominent pedagogue, well known through his writings. He confines

himself in his _School_ to teaching only that which is well established

and accepted without a doubt. As a practical man who addresses himself

mainly to teachers of primary grades, he would not place himself on the

pinnacle of the outcome of philosophy, even if he could. He must confine

himself to that which is well established, which is far removed from the

disputes of the day. But it may here serve as a whetstone by the help of

which we may give to the positive product of philosophy its latest and

greatest sharpness.

He writes right in the beginning of the first part: "Our ideas are as

manifold as the objects to which they refer. Several things may have

many or few, or at least one quality, in common. Still they may also be

totally different."

This last point, viz., that there may be things which are "totally"

different from one another, is the one which is decidedly rejected by

that science which has risen to the eminence of the positive acquisition

of philosophy. There can be no natural things which are "totally"

different from one another, because they must all of them have in common

the quality of being natural.

It sounds very commonplace to say that there are no unnatural things in

nature. Since the last witch was burnt, everybody is sufficiently

enlightened to know that. But the logical conclusions of natural monism

have not yet been drawn. True, natural science, properly socalled, is

busily engaged in arriving at them. But so much more strife is there in

the "science of mind" and there is no other remedy but a well founded

theory of understanding which teaches that nature is not alone absolute

nature, but also the nature of the absolute. From this doctrine it

necessarily follows that all things are not individually independent,

but related by sex, dependent children, "predicates" of the monistic

unity of the world.

"The arch fountain of the human spirit," says Dittes, "is perception....

Whether perception as such discloses to us the true nature of things, or

whether it makes us familiar only with their phenomena, this is not to

be discussed by logic." The practical pedagogue who confines himself to

the education of children's brains or who wishes at most to influence

such teachers as educate children's brains, is quite right in being

satisfied with the old traditional Aristotlean logic. But in the school

of the human race, this logic has not been sufficient. For this reason

the philosophers have broached the question whether perception, "the

arch fountain of the human spirit," is a true or a deceptive fountain.

The product of the philosophical investigation which we here offer

amounts to the declaration that the logicians are greatly mistaken about

the "arch fountain." It is a cardinal error of ancient logic to regard

perception as the ultimate source from which the human mind dips its

knowledge. It is nature which is the ultimate source, and our perception

is but the mediator of understanding. And its product, recognized

truth, is not truth itself, but merely a formal picture of it. Universal

nature is the arch fountain, is the eternal and imperishable truth

itself, and our perception, like every other part of universal

existence, is only an attribute, a particle of absolute nature. The

human mind, with whose nature logic is dealing, is no more an

independent thing than any other, but simply a phenomenon, a reflex or

predicate of nature.

To confound true perceptions or perceived truths with general truth,

with the _non plus ultra_ of all truths, is equivalent to regarding a

sparrow as _the_ bird in general, or a period of civilization as

civilization itself, which would mean the closing of the door to all

further development.

Modern philosophy, beginning with Bacon of Verulam and closing with

Hegel, carries on a constant struggle with the Aristotlean logic. The

product of this struggle, the outcome of philosophy, does not deny the

old rules of traditional logic, but adds a new and decidedly higher

circle of logical perception to the former ones. For the sake of better

understanding it may be well to give to this circle a special title, the

special name of "theory of understanding," which is sometimes called

"dialectics."

In order to demonstrate the essential contents of this philosophical

product by an investigation of the fundamental laws of traditional logic

and to explain it thereby, I refer once more to the teacher of

elementary logic, Dittes.

Under the caption of "Principles of Judgment" he teaches: "Since

judging, like all thinking, aims at the perception of truth, the rules

have been sought after by which this purpose might be accomplished. As

universally applicable rules, as principles or laws of thought, the

following four have been named:

(1) The law of uniformity (identity).

(2) The law of contradiction.

(3) The law of the excluded third.

(4) The law of adequate cause."

So much scholastic talk has been indulged in over these four

"principles," that I can hardly bring myself to discuss them further.

But since my purpose, the demonstration of the positive outcome of

philosophy, consists in throwing a new light on the logic contained in

these four so-called principles or laws, I am compelled to lay bare

their inmost kernel.

The first principle, then, declares that A is A, or to speak

mathematically, every quantity is equal to itself. In plain English: a

thing is what it is; no thing is what it is not. "Characters which are

excluded by any conception must not be attributed to it." The square is

excluded from the conception of a circle, therefore the predicate

"square" must not be given to a circle. For the same reason a straight

line must not be crooked, and a lie must not be true.

Now this so-called law of thought may be well enough for household use,

where nothing but known quantities are under consideration. A thing is

what it is. Right is not left and one hundred is not one thousand.

Whoever is named Peter or Paul remains Peter or Paul all his life. This,

I say, is all right for household use.

But when we consider matters from the wider point of view of cosmic

universal life, then this famous law of thought proves to be nothing but

an expedient in logic which is not adequate to the nature of things, but

merely a means of mutual understanding for us human beings. Hence the

left bank of the Rhine is not the right, because we have agreed that in

naming the banks of a river we will turn our backs to the source and our

faces to the mouth of the river and then designate the banks as right

and left. Such a way of distinguishing, thinking, and judging is good

and practical, so long as this narrow standpoint is accompanied by the

consciousness of its narrowness. Hitherto this has not been the case.

This determined logic has overlooked that the perception which is

produced by its rules is not truth, not the real world, but only gives

an ideal, more or less accurate, reflection of it. Peter and Paul, who

according to the law of identity are the same all their lives, are in

fact different fellows every minute and every day of their lives, and

all things of this world are, like those two, not constant, but very

variable quantities. The mathematical points, the straight lines, the

round circles, are ideals. In reality every point has a certain

dimension, every straight line, when seen through a magnifying glass, is

full of many crooked turns, and even the roundest circle, according to

the mathematicians, consists of an infinite number of straight lines.

The traditional logic, then, declares with its law of identity, or in

the words of Dittes "law of uniformity," that Peter and Paul are the

same fellows from beginning to end, or that the western mountains remain

the same western mountains so long as they exist. The product of modern

philosophy, on the other hand, declares that the identity of people,

woods, and rocks is inseparably linked to their opposite, their

incessant transformation. The old school logic treats things, the

objects of perception, like stereotyped moulds, while the

philosophically expanded logic considers such treatment adequate for

household use only. The logical household use of stereotyped

conceptions extends, and should extend, to all of science. The

consideration of things as remaining "the same" is indispensable, and

yet it is very salubrious to know and remember that the things are not

only the same permanent and stereotyped, but at the same time variable

and in flow. That is a contradiction, but not a senseless one. This

contradiction has confused the minds and given much trouble to the

philosophers. The solution of this problem, the elucidation of this

simple fact, is the positive product of philosophy.

I have just declared that logic so far did not know that the perception

produced by its principles does not offer us truth itself, but only a

more or less accurate picture of it. I have furthermore contended that

the positive outcome of philosophy has materially added to the clearness

of the portrait of the human mind. Logic claims to be "the doctrine of

the forms and laws of thought." Dialectics, the product of philosophy,

aims to be the same, and its first paragraph declares: Not thought

produces truth, but being, of which thought is only that part which is

engaged in securing a picture of truth. The fact resulting from this

statement may easily confuse the reader, viz., that the philosophy which

has been bequeathed to us by logical dialectics, or dialectic logic,

must explain not alone thought, but also the original of which thought

is a reflex.

While, therefore, traditional logic teaches in its first law that all

things are equal to themselves, the new dialectics teaches not only that

things are equal to themselves and identical from start to finish, but

also that these same things have the contradictory quality of being the

same and yet widely variable. If it is a law of thought that we gain as

accurate as possible a conception of things by the help of thought, it

is at the same time a law of thought that all things, processes, and

proceedings are not things but resemble the color of that silk which,

although equal to itself and identical throughout, still plays from one

color into another. The things of which the thinking thing or human

intellect is one are so far from being one and the same from beginning

to end that they are in truth and fact without beginning and end. And as

phenomena of nature, as parts of infinite nature, they only seem to have

a beginning and end, while they are in reality but natural

transformations arising temporarily from the infinite and returning into

it after a while.

Natural truth or true nature, without beginning and end, is so

contradictory that it only expresses itself by shifting phenomena which

are nevertheless quite true. To old line logic this contradiction

appears senseless. It insists on its first, second, and third law, on

its identity, its law of contradiction and excluded third, which must be

either straight or crooked, cold or warm, and excludes all intermediary

conceptions. And in a way it is right. For every-day use it is all right

to deal in this summary fashion with thoughts and words. But it is at

the same time judicious to learn from the positive outcome of philosophy

that in reality and truth things do not come to pass so ideally. The

logical laws think quite correctly of thoughts and their forms and

applications. But they do not exhaust thinking and its thoughts. They

overlook the consciousness of the inexhaustibleness of all natural

creations, of which the object of logic, human understanding, is a part.

This object did not fall from heaven, but is a finite part of the

infinite which actually has the contradictory quality of possessing in

and with its logical nature that universal nature which is superior to

all logic.

From this critique of the three first "fundamental laws of logic" it is

apparent that the human understanding is not only everywhere identical,

but also different in each individual and has a historical development.

We are, of course, logically entitled to consider this faculty like all

others by itself and give it a birthday. Wherever man begins, there

understanding, the faculty of thought, begins. But we are

philosophically and dialectically no less entitled, and it is even our

duty, to know that the faculty of understanding, the same as its human

bearer, has no beginning, in spite of the fact that we ascribe a

beginning to them. When we trace the historical development of these

two, of man and understanding, backward to their origin, we arrive at a

transition to the animal and see their special nature merging into

general nature. The same is found in tracing the development of the

individual mind. Where does consciousness begin in the child? Before,

at, or after birth? Consciousness arises from its opposite,

unconsciousness, and returns to it. In consequence we regard the

unconscious as the substance and the conscious as its predicate or

attribute. And the fixed conceptions which we make for ourselves of the

units or phenomena of the natural substance are recognized by us as

necessary means in explaining nature, but at the same time it is

necessary to learn from dialectics that all fixed conceptions are

floating in a liquid element. The infinite substance of nature is a very

mobile element, in which all fixed things appear and sink, thus being

temporarily fixed and yet not fixed.

Now let us briefly review the fourth fundamental law of logic, according

to which everything must have an adequate cause. This law is likewise

very well worthy of attention, yet it is very inadequate, because the

question what should be our conception of the world and what is the

constitution of the most highly developed thinking faculty of the world

requires the answer: the world, in which everything has its adequate

cause, is nevertheless, including consciousness and the faculty of

thought, without beginning, end, and cause, that is, a thing justified

in itself and by itself. The law of the adequate cause applies only to

pictures made by the human mind. In our logical pictures of the world

everything must have its adequate cause. But the original, the universal

cosmos, has no cause, it is its own cause and effect. To understand that

all causes rest on the causeless is an important dialectic knowledge

which first throws the requisite light on the law of the necessity of an

adequate cause.

Formally everything must have its cause. But really everything has not

only one cause, but innumerable causes. Not alone father and mother are

the cause of my existence, but also the grand parents and great grand

parents, together with the air they breathed, the food they ate, the

earth on which they walked, the sun which warmed the earth, etc. Not a

thing, not a process, not a change is the adequate cause of another, but

everything is rather caused by the universe which is absolute.

When philosophy began its career with the intention of understanding the

world, it soon discovered that this purpose could be accomplished only

by special study. When it chose understanding, or the faculty of

thought, as the special object of its study, it separated its specific

object too far from the general existence. Its logic, in opposing

thought to the rest of existence, forgot the interconnection of the

opposites, forgot that thought is a form, a species, an individuality

which belongs to the genus of existence, the same as fish to the genus

of meat, night to the genus of day, art to nature, word to action, and

death to life. It does not attempt to explore the essence of thought for

its own sake, but for the purpose of discovering the rules of exploring

and thinking correctly. It could not very well arrive at those coveted

rules, so long as it idealized truth transcendentally and elevated it

far above the phenomena. All phenomena of nature are true parts of

truth. Even error and lies are not opposed to truth in that exaggerated

sense in which the old style logic represents them, which teaches that

two contradictory predicates must not be simultaneously applied to the

same subject, that any one subject is either true or false, and that any

third alternative is out of the question. Such statements are due to an

entire misconception of truth. Truth is the absolute, universal sum of

all existing things, of all phenomena of the past, present, and future.

Truth is the real universe from which errors and lies are not excluded.

In so far as stray thoughts, giants and brownies, lies and errors are

really existing, though only in the imagination of men, to that extent

they are true. They belong to the sum of all phenomena, but they are not

the whole truth, not the infinite sum. And even the most positive

knowledge is nothing but an excellent picture of a certain part. The

pictures in our minds have this in common with their originals that they

are true. All errors and lies are true errors and true lies, hence are

not so far removed from truth that one should belong to heaven and the

other to eternal damnation. Let us remain human.

Since old line logic with its four principles was too narrowminded, its

development had to produce that dialectics which is the positive

outcome of philosophy. This science of thought so expanded regards the

universe as the truly universal or infinite, in which all contradictions

slumber as in the womb of conciliation. Whether the new logic shall have

the same name as the old, or assume the separate title of theory of

understanding or dialectics, is simply a question of terms which must be

decided by considerations of expediency.
