(3) Then passing on to the Physical Plane, they illustrate the Principle by showing that Heat and Cold are identical in nature, the differences being merely a matter of degrees. The thermometer shows many degrees of temperature, the lowest pole being called "cold," and the highest "heat." Between these two poles are many degrees of "heat" or "cold," call them either and you are equally correct. The higher of two degrees is always "warmer," while the lower is always "colder." There is no absolute standard-all is a matter of degree. There is no place on the thermometer where heat ceases and cold begins. It is all a matter of higher or lower vibrations. The very terms "high" and "low," which we are compelled to use, are but poles of the same thing-the terms are relative. So with "East and West"--travel around the world in an eastward direction, and you reach a point which is called west at your starting point, and you return from that westward point. Travel far enough North, and you will find yourself traveling South, or vice versa.

(6) And so it is on the Mental Plane. "Love and. Hate" are generally regarded as being things diametrically opposed to each other; entirely different; unreconcilable. But we apply the Principle of Polarity; we find that there is no such thing as Absolute Love or Absolute Hate, as distinguished from each other. The two are merely terms applied to the two poles of the same thing. Beginning at any point of the scale we find "more love," or "less hate," as we ascend the scale; and "more hate" or "less love" as we descend this being true no matter from what point, high or low, we may start. There are degrees of Love and Hate, and there is a middle point where "Like and Dislike" become so faint that it is difficult to distinguish between them. Courage and Fear come under the same rule. The Pairs of Opposites exist everywhere. Where you find one thing you find its opposite-the two poles.

(4) Light and Darkness are poles of the same thing, with many degrees between them. The musical scale is the same--starting with "C" you move upward until you reach another "C" and so on, the differences between the two ends of the board being the same, with many degrees between the two extremes. The scale of color is the same-higher and lower vibrations being the only difference between high violet and low red. Large and Small are relative. So are Noise and Quiet; Hard and Soft follow the rule. Likewise Sharp and Dull. Positive and Negative are two poles of the same thing, with countless degrees between them.

(4) 4. The Principle of Polarity "Everything is Dual; everything has poles; everything has its pair of opposites; like and unlike are the same; opposites are identical in nature, but different in degree; extremes meet; all truths are but half-truths; all paradoxes may be reconciled." --The Kybalion. This Principle embodies the truth that "everything is dual"; "everything has two poles"; "everything has its pair of opposites," all of which were old Hermetic axioms. It explains the old paradoxes, that have perplexed so many, which have been stated as follows: "Thesis and antithesis are identical in nature, but different in degree"; "opposites are the same, differing only in degree"; "the pairs of opposites may be reconciled"; "extremes meet"; "everything is and isn't, at the same time"; "all truths are but half-truths"; "every truth is half-false"; "there are two sides to everything," etc., etc., etc. It explains that in everything there are two poles, or opposite aspects, and that "opposites" are really only the two extremes of the same thing, with many varying degrees between them. To illustrate: Heat and Cold, although "opposites," are really the same thing, the differences consisting merely of degrees of the same thing. Look at your thermometer and see if you can discover where "heat" terminates and "cold" begins! There is no such thing as "absolute heat" or "absolute cold"--the two terms "heat" and "cold" simply indicate varying degrees of the same thing, and that "same thing" which manifests as "heat" and "cold" is merely a form, variety, and rate of Vibration. So "heat" and "cold" are simply the "two poles" of that which we call "Heat"--and the phenomena attendant thereupon are manifestations of the Principle of Polarity. The same Principle manifests in the case of "Light and Darkness," which are the same thing, the difference consisting of varying degrees between the two poles of the phenomena. Where does "darkness" leave off, and "light" begin? What is the difference between "Large and Small"? Between "Hard and Soft"? Between "Black and White"? Between "Sharp and Dull"? Between "Noise and Quiet"? Between "High and Low"? Between "Positive and Negative"? The Principle of Polarity explains these paradoxes, and no other Principle can supersede it. The same Principle operates on the Mental Plane. Let us take a radical and extreme example--that of "Love and Hate," two mental states apparently totally different. And yet there are degrees of Hate and degrees of Love, and a middle point in which we use the terms "Like or Dislike," which shade into each other so gradually that sometimes we are at a loss to know whether we "like" or "dislike" or "neither." And all are simply degrees of the same thing, as you will see if you will but think a moment. And, more than this (and considered of more importance by the Hermetists), it is possible to change the vibrations of Hate to the vibrations of Love, in one's own mind, and in the minds of others. Many of you, who read these lines, have had personal experiences of the involuntary rapid transition from Love to Hate, and the reverse, in your own case and that of others. And you will therefore realize the possibility of this being accomplished by the use of the Will, by means of the Hermetic formulas. "Good and Evil" are but the poles of the same thing, and the Hermetist understands the art of transmuting Evil into Good, by means of an application of the Principle of Polarity. In short, the "Art of Polarization" becomes a phase of "Mental Alchemy" known and practiced by the ancient and modern Hermetic Masters. An understanding of the Principle will enable one to change his own Polarity, as well as that of others, if he will devote the time and study necessary to master the art.

(16) Heat is set in opposition unto it, and qualifieth therein, as if it were one and the same thing; but cold opposeth the fierceness or rage of the heat, and allayeth the heat.

(20) We have to ascertain whether there is not to every quality a contrary. In the case of virtue and vice, even the mean appears to be contrary to the extremes.

But when we turn to colours, we do not find the intermediates so related. If we regard the intermediates as blendings of the extremes, we must not posit any contrariety other than that between black and white, but must show that all other colours are combinations of these two. Contrariety however demands that there be some one distinct quality in the intermediates, though this quality may be seen to arise from a combination.

It may further be suggested that contraries not only differ from each other, but also entail the greatest possible difference. But "the greatest possible difference" would seem to presuppose that intermediates have already been established: eliminate the series, and how will you define "the greatest possible"? Sight, we may be told, will reveal to us that grey is nearer than black to white; and taste may be our judge when we have hot, cold and no intermediate.

That we are accustomed to act upon these assumptions is obvious enough; but the following considerations may perhaps commend themselves:

White and yellow are entirely different from each other- a statement which applies to any colour whatsoever as compared with any other; they are accordingly contrary qualities. Their contrariety is independent of the presence of intermediates: between health and disease no intermediate intrudes, and yet they are contraries.

It may be urged that the products of a contrariety exhibit the greatest diversity. But "the greatest diversity" is clearly meaningless, unless we can point to lower degrees of diversity in the means. Thus, we cannot speak of "the greatest diversity" in reference to health and disease. This definition of contrariety is therefore inadmissible.

Suppose that we say "great diversity" instead of "the greatest": if "great" is equivalent to greater and implies a less, immediate contraries will again escape us; if, on the other hand, we mean strictly "great" and assume that every quality shows a great divergence from every other, we must not suppose that the divergence can be measured by a comparative.

Nonetheless, we must endeavour to find a meaning for the term "contrary." Can we accept the principle that when things have a certain similarity which is not generic nor in any sense due to admixture, but a similarity residing in their forms- if the term be permitted- they differ in degree but are not contraries; contraries being rather those things which have no specific identity? It would be necessary to stipulate that they belong to the same genus, Quality, in order to cover those immediate contraries which have nothing conducing to similarity, inasmuch as there are no intermediates looking both ways, as it were, and having a mutual similarity to each other; some contraries are precluded by their isolation from similarity.

If these observations be sound, colours which have a common ground will not be contraries. But there will be nothing to prevent, not indeed every colour from being contrary to every other, but any one colour from being contrary to any other; and similarly with tastes. This will serve as a statement of the problem.

As for Degree , it was given as our opinion that it exists in the objects participating in Quality, though whether it enters into qualities as such- into health and justice- was left open to question. If indeed these qualities possess an extension quite apart from their participants, we must actually ascribe to them degrees: but in truth they belong to a sphere where each entity is the whole and does not admit of degree.

(23) These two [air and water] are caused by heat and cold, and qualify or mix and operate together as one thing.

(1) The great Fourth Hermetic Principle--the Principle of Polarity embodies the truth that all manifested things have "two sides"; "two aspects"; "two poles"; a "pair of opposites," with manifold degrees between the two extremes. The old paradoxes, which have ever perplexed the mind of men, are explained by an understanding of this Principle. Man has always recognized something akin to this Principle, and has endeavored to express it by such sayings, maxims and aphorisms as the following: "Everything is and isn't, at the same time"; "all truths are but half-truths"; "every truth is half-false"; "there are two sides to everything"--"there is a reverse side to every shield," etc., etc.

(2) The Hermetic Teachings are to the effect that the difference between things seemingly diametrically opposed to each other is merely a matter of degree. It teaches that "the pairs of opposites may be reconciled," and that "thesis and anti-thesis are identical in nature, but different in degree"; and that the "universal reconciliation of opposites" is effected by a recognition of this Principle of Polarity. The teachers claim that illustrations of this Principle may be had on every hand, and from an examination into the real nature of anything. They begin by showing that Spirit and Matter are but the two poles of the same thing, the intermediate planes being merely degrees of vibration. They show that THE ALL and The Many are the same, the difference being merely a matter of degree of Mental Manifestation. Thus the LAW and Laws are the two opposite poles of one thing. Likewise, PRINCIPLE and Principles. Infinite Mind and finite minds.

(17) Cold containeth also two sorts or species in it, which are to be observed, viz. It mitigateth the heat, makes all things pleasant, and is in all creatures a quality of life; for no creature can subsist without cold; for it is a springing, driving mobility in every thing.

(8) The student who is familiar with the processes by which the various schools of Mental Science, etc., produce changes in the mental states of those following their teachings, may not readily understand the principle underlying many of these changes. When, however, the Principle of Polarity is once grasped, and it is seen that the mental changes are occasioned by a change of polarity-a sliding along the same scale-the hatter is readily understood. The change is not in the nature of a transmutation of one thing into another thing entirely different-but is merely a change of degree in the same things, a vastly important difference. For instance, borrowing an analogy from the Physical Plane, it is impossible to change Heat into Sharpness, Loudness, Highness, etc., but Heat may readily be transmuted into Cold, simply by lowering the vibrations. In the same way Hate and Love are mutually transmutable; so are Fear and Courage. But Fear cannot be transformed into Love, nor can Courage be transmuted into Hate. The mental states belong to innumerable classes, each class of which has its opposite poles, along which transmutation is possible.

(9) The student will readily recognize that in the mental states, as well as in the phenomena of the Physical Plane, the two poles may be classified as Positive and Negative, respectively. Thus Love is Positive to Hate; Courage to Fear; Activity to Non-Activity, etc., etc. And it will also be noticed that even to those unfamiliar with the Principle of Vibration, the Positive pole seems to be of a higher degree than the Negative, and readily dominates it. The tendency of Nature is in the direction of the dominant activity of the Positive pole.

(19) Air has its original from heat and cold; for heat and cold work powerfully and replenish all, whereby is caused a lively and stirring motion; but when cold allayeth or mitigateth the heat, then both their qualities are rarefied and made thin; and the bitter quality attracteth or concreteth them together, so that they become dewy.

(15) Cold is a quality also, as well as heat; it qualifieth or operateth in all creatures whatsoever that come forth in nature, and in all whatsoever that move therein, in men, beasts, fowls, fishes, worms, leaves and grass.

(8) It is a general principle that, to be modified, an object must be opposed in faculty, and in quality to the forces that enter and act upon it.

Thus where heat is present, the change comes by something that chills, where damp by some drying agency: we say a subject is modified when from warm it becomes cold, from dry wet.

A further evidence is in our speaking of a fire being burned out, when it has passed over into another element; we do not say that the Matter has been burned out: in other words, modification affects what is subject to dissolution; the acceptance of modification is the path towards dissolution; susceptibility to modification and susceptibility to dissolution go necessarily together. But Matter can never be dissolved. What into? By what process?

Still: Matter harbours heat, cold, qualities beyond all count; by these it is differentiated; it holds them as if they were of its very substance and they blend within it- since no quality is found isolated to itself- Matter lies there as the meeting ground of all these qualities with their changes as they act and react in the blend: how, then, can it fail to be modified in keeping? The only escape would be to declare Matter utterly and for ever apart from the qualities it exhibits; but the very notion of Substance implies that any and every thing present in it has some action upon it.

(23) First there is the astringent quality, then the sweet, and next the bitter: The sweet is in the midst between the astringent and the bitter. Now the astringent causes things to be hard, cold and dark; and the bitter teareth, driveth, rageth and divideth or distinguished. These two qualities rub and drive each other so hard, and move so eagerly, that they generate the heat, which now in these two qualities is dark, even as heat in a stone is.

(523) do not pass from one sensation to the opposite; inviting objects are those which do; in this latter case the sense coming upon the object, whether at a distance or near, gives no more vivid idea of anything in particular than of its opposite. An illustration will make my meaning clearer:—here are three fingers—a little finger, a second finger, and a middle finger. Very good. You may suppose that they are seen quite close: And here comes the point. What is it? Each of them equally appears a finger, whether seen in the middle or at the extremity, whether white or black, or thick or thin—it makes no difference; a finger is a finger all the same. In these cases a man is not compelled to ask of thought the question what is a finger? for the sight never intimates to the mind that a finger is other than a finger. True. And therefore, I said, as we might expect, there is nothing here which invites or excites intelligence. There is not, he said. But is this equally true of the greatness and smallness of the fingers? Can sight adequately perceive them? and is no difference made by the circumstance that one of the fingers is in the middle and another at the extremity? And in like manner does the touch adequately perceive the qualities of thickness or thinness, of softness or hardness? And so of the other senses; do they give perfect intimations of such matters?

(7) And it is this fact that enables the Hermetist to transmute one mental state into another, along the lines of Polarization. Things belonging to different classes cannot be transmuted into each other, but things of the same class may be changed, that is, may have their polarity changed. Thus Love never becomes East or West, or Red or Violet-but it may and often does turn into Hate and likewise Hate may be transformed into Love, by changing its polarity. Courage may be transmuted into Fear, and the reverse. Hard things may be rendered Soft. Dull things become Sharp. Hot things become Cold. And so on, the transmutation always being between things of the same kind of different degrees. Take the case of a Fearful man. By raising his mental vibrations along the line of Fear- Courage, he can be filled with the highest degree of Courage and Fearlessness. And, likewise, the Slothful man may change himself into an Active, Energetic individual simply by polarizing along the lines of the desired quality.

(100) Thou must see that all this is really so. For example, take a root which is of a hot quality, put it in warm water, or take it into thy mouth, and make it warm and supple or moist; then thou wilt soon perceive its life, and active or operative quality: But so long as it is without or absent from the heat, it is captivated in death, and is cold, as any other root or piece of wood is.

(25) And the same thing becomes the cause of contrary effects; sometimes through the magnitude of the cause and its power, and sometimes in consequence of the susceptibility of that on which it acts. According to the nature of the force, the same string, according to its tension or relaxation, gives a shrill or deep sound. And honey is sweet to those who are well, and bitter to those who are in fever, according to the state of susceptibility of those who are affected. And one and the same wine inclines some to rage, and others to merriment. And the same sun melts wax and hardens clay.
