the divine Providence. It has been the most universal and cosmopolitan instructor of the human race and is so still. Instruction and learning are together the knowledge and experience of what is. Stars, animals and plants are ignorant of their law--it does not come into their experience; but man only then exists conformably to the principle of his being when he knows what he is and by what he is surrounded. He must recognize the powers by which he is driven or influenced; and it is just such a knowledge which poetry, in its original and vital[2] form, supplies.
(_b_) It is, however, also a content of the same character which belongs to man's _ordinary_ conscious life. This too instructs him in general laws, as such at least are interpreted by the motley crowd of human life, in their distinction, coordination, and significance. The question therefore arises, as previously observed, as to the nature of the distinction between the mode of conception severally adopted by prose and poetry, a similarity in the content of each being assumed as possible.
(_α_) Poetry is of greater antiquity than speech modelled in the artistic form of elaborate prose. It is the _original_ imaginative grasp of truths a form of knowledge, which fails as yet to separate the universal from its living existence in the particular object, which does not as yet contrast law land phenomena, object and means, or relate the one to the other in subordination to the process of human reason, but comprehends the one exclusively in the other and by virtue of the other. For this reason it does not merely, under the mode of imagery, express a content already essentially apprehended in its universality; on the contrary it lingers, conformably to its unmediated notion, in the unity of concrete life itself, which has not as yet effected such a separation or such an association of mere relationship.
(_αα_) Under the above forms of envisualization, poetry posits all that it comprehends as an exclusive and consequently independent totality, which, despite its capacity for a rich content and an extensive range of condition, individuals, actions, events, emotions and ideas of every kind, nevertheless is forced to exhibit the same in all their wide complexity as an essentially self-determined whole, as displayed and motived by the unity, whose individual expression this or that fact in its singularity actually is. And consequently the universal or rational principle is not expressed in poetry in its abstract universality, or in the complexus which lies open to philosophical exposition or under the relation of its varied aspects apprehended by science, but on the contrary as a vital union, in its phenomenal presence, possessed with soul and self-determined throughout; and it is further expressed in such a way that the all-embracing unity, the real soul of its vitality, is only suffered to be operative in mysterious guise from within outwards.
(_ββ_) The character of this mode of apprehending, reclothing and expressing fact is throughout one of construction. It is not the fact itself and its _contemplative_[3] existence, but reconstruction and speech which are the object of poetry. Its entrance on the scene dates from the first efforts of man at self-expression. What is expressed is simply made use of to satisfy this desire. The instant man, in the midst of his practical activities and imperative duties, seeks to summarize this effect for mind and to communicate himself to others, then we have some kind of artistic expression, some accord with what is poetical. To mention one from a host of examples, there is that distich which we read in Herodotus referring to the slain heroes of Thermopylae. As for its content it is simply the fact, the bare announcement that four thousand Peloponesians on a certain spot fought the battle with three hundred myriads. The main interest is, however, the composition of an inscription which communicates to contemporary life and posterity the historical fact, and is there exclusively to do so. In other words, the expression of this fact is poetical; it testifies to itself as a deed (εἱν ποιείν) which leaves the content in its simplicity, but expresses the same with a definite purpose. The language, in which the idea is embodied, is to that extent of such increased value that an attempt is made to distinguish it from ordinary speech; we have a distich in lieu of a sentence.
(_γγ_) For this reason, even from the point of view of language, poetry makes an effort to keep its domain singular and distinct from ordinary parlance, and to accomplish this elevates its expression to a higher virtue than that of merely articulate expression. We must, however, not only in this particular respect, but for the purposes of our present inquiry generally, make an essential distinction between a primitive poetry, which arises _previous to_ the creation of ordinary artificial prose, and that mode of poetical composition and speech the development of which is effected where already the conditions of our everyday life and prosaic expression exist. The first is poetical without intention, in idea no less than speech; the latter, on the contrary, is fully conscious of the sphere, from which its task is to detach itself, in order that it may establish itself on the free basis of art. It is consequently quite aware of the distinction and contrast implied in its self-creation to the world of prose.
(_β_) _Secondly_, the kind of _prose life_, from which poetry has to separate itself, postulates an entirely different nature of conception and speech.
(_αα_) In other words, looked at from one point of view, such a consciousness regards the wide expanse of reality according to that association of cause and effect, object and means, and all other categories of the mode of reflection which deals with _finite_ conditions and the objective world generally, that is, the limited categories of science or the understanding. It is a feature of such thought that every particular trait should at one moment appear with a false subsistency, at another should be placed in the position of _bare_ relation to something else, that as such it should be so apprehended in its relativity and dependence that no unity of a free nature whatever is possible, no unity, that is, which remains essentially throughout, and in all its branches and separate filaments, a complete and free totality, no unity, in short, where we find that the individual aspects are simply the appropriate explication and phenomenal presence of _one_ content which constitutes the point of focus, the soul that unites all together, and which also finds its vital principle in this all-pervading centre of animation. Rather the type of conception we above refer to as that of science goes no further than the discovery of particular laws in phenomena, and persists for this reason in the separation, or bare relation, of the particular existence with its general law, the laws themselves under this view tending to harden from each other in their isolate singularity; that their relation is, in fact, conceived exclusively under external and finite conditions.
(_ββ_) And, furthermore, man's _ordinary_ consciousness has nothing to do with what we call the ideal principle of association, the essential core of facts, their bases, causes, ends, and so forth. It rests satisfied with the acceptance of the mere fact that something exists or happens as distinct from something else; or, in other words, with its insignificant contingency. It is no doubt true that the unity of life is not, in such a case, deliberately cancelled by any express separation; that unity, I mean, in which the intuition of the poet arrests the ideal _rationale_ of the fact, its expression and determinate existence. What, however, is absent here, is just that flash of insight into this core of reason and significance, which becomes consequently for our intelligence a thing essentially vacant, possessing no further claim on our minds to a rational interest. The comprehension of a rational cosmos; and its relations is exchanged then and there for a mere flux and contiguity of indifference, which it is true may possess a large expanse of external animation, but which none the less suffers the profounder impulse of reason[4] to remain unsatisfied. True vision, no less than soul-life in its full vigour, can only obtain satisfaction, where such are made aware in phenomena, through feeling no less than contemplation, of the reality in its essence and truth which is compatible with such a world. The life which is a mere external show is defunct to our deeper sense, if all that is ideal and intrinsically rich in significance fails to shine through as the very soul thereof.
(_γγ_) These defects, thirdly, in the conceptions of science and our ordinary conscious life _speculative thought_ effaces. It stands, therefore, in one respect in affinity with the imagination of the poet.
The cognizance of reason[5] is not solely, or even mainly, concerned with contingent singularity, nor does it overlook in the phenomenal world the essence of the same. It does not rest satisfied with the differentiations and external relations proper to the conceptions and deductions of the understanding; it unites them in a free totality, which in the apprehension of our finite faculty in part fails to preserve its self-consistency, and in part is posited in a relation that possesses no synthetic unity. Pure thought, however, can have but one result, namely thoughts. It evaporates the mode of reality in that of the pure notion. And although it grasps and comprehends actual things in their essential separation and their actual existence, it does also nevertheless translate this particularity into the ideal element of the universal, in which alone thought is at home with itself. Consequently there arises, in contrast to the world of phenomena, a world that is new in this sense, that though the truth of the Real is present, it is not displayed in _reality_ itself as the power itself which gives it form and the veritable soul thereof. Thinking is simply a reconciliation of truth with reality in _Thought._ The creations and reconstruction, however, of the poet is a reconciliation under the mode of phenomenal reality itself, albeit such a _real appearance_ is merely ideally conceived.
(_γ_) We have, therefore, two distinct spheres of consciousness, that of poetry and prose. In former times, in which there is neither present a deliberate outlook on the world elaborated, in respect to its religious belief and its general knowledge, under the co-ordinated form of scientific ideas and cognition, nor an actual world of human condition regulated conformably to such a standard, poetry is confronted with a lighter task. Prose is not in such a case opposed to it as an essentially independent field of ideal and external existence, which it has first to overcome. Its problem is for the most part simply limited to deepening all that is significant or transparent in the forms of ordinary consciousness. If, on the contrary, the prose of life has already appropriated within its mode of vision the entire content of conscious life, setting its seal on all and every part of it, the art of poetry is forced to undertake the task of melting all down again and re-coining the same anew. In every direction it finds itself involved in difficulties by the unresponsive nature of prosaic existence. It has, in short, not only to wrest itself from the adherence of ordinary consciousness to all that is indifferent and contingent, and to raise the scientific apprehension of the cosmos of fact to the level of reason's profounder penetration, or to translate speculative thought into terms of the imagination, giving a body to the same in the sphere of intelligence itself; it has further to convert in many ways the _mode of expression_ common to the ordinary consciousness into that appropriate to poetry; and, despite of all deliberate intention enforced by such a contrast and such a process, to make it appear as though all such purpose was absent, preserving the original freedom essential to all art.
(_c_) We have now summarized in its most general terms that in which the content of poetry consists. We have further distinguished the form of poetry from that of prose. In conclusion, it is of importance to draw attention to the particularization which the art of poetry, to a degree unattained by the other arts, whose development is not nearly so rich in results, admits of. We find, no doubt, architecture illustrated in the arts of very varied peoples, and continuous through many centuries. But of sculpture, at least, it is true that it reaches its culminating point in the ancient world of Greece and Rome, just as painting and music have done more recently in Christendom. The art of poetry celebrates its epochs of brilliancy and bloom among all nations and in all ages almost that present any real artistic activity at all.
It embraces the collective Spirit of mankind, and it is differentiated through every kind of variation.
(_α_) Furthermore, inasmuch as poetry does not accept the universal in scientific abstraction from its object, but seeks to represent what is rational under the mode of individuality,[6] the specific traits of national character are essential to its growth; the content and the particular mode of its presentation are in fact conditioned by the nature of these and the general outlook in each case. We find it consequently adapting itself to every variety of form and peculiarity.
It matters not what the poetry may be, whether Oriental, Italian, Spanish, English, Roman, Hellenic, or German, each and all differ totally in their spirit, emotional impulse, general outlook and expression.
A similar distinctive variety asserts itself in particular epochs as they are favourable to the art of poetry or the reverse. The results secured, for example, by our German poetry were impossible in the Middle Ages, or the times of the thirty years' war. The particular motives, which in our own day excite the greatest interest, are inseparable from the entire evolution of contemporary life. And in the same way every age has its own wider or more restricted, more exalted and liberal, or more depressed phase of emotional life, in short its specific outlook on the world, which it is the express aim of poetry to bring home to the artistic consciousness in the most intelligible and complete manner, inasmuch as language is the one medium capable of expressing the human spirit wherever and in whatever form it may be manifested.
(_β_) Among these national characteristics, or views and opinions peculiar to particular epochs, some have closer affinity with the poetic impulse than others. The Oriental consciousness is, for example, in general more poetic than the Western mind, if we exclude Greece.
In the East the principle predominant is always that of coherence, solidity, unity, substance. An outlook of this nature is intrinsically most penetrative, even though it may fail to reach the freedom of the Ideal. Our Western point of view, especially that of modern life, is based on the endless breaking up and division of its boundless material into fragments, in virtue of which process, the extreme emphasis laid here on particular facts, what is merely finite becomes substantive for the imagination, and despite of this must be once more subsumed under the converse action of relativity. For the Oriental nothing persists as really substantive, but everything appears as contingent, discovering its supreme focus, stability and final justification in the One, the Absolute, to which it is referred.
(_γ_) By means of this diversity of national traits and the evolutionary process of the centuries we find that what is shared by all mankind alike, no less than all that claims to be artistic, is drawn as a common element within the reach of other nations and epochs, intelligible and enjoyable to the same. It is in this twofold connection that of late years to an exceptional degree Hellenic poetry has roused the admiration and imitation of most diverse nationalities.
And this is so because in the content of it no less than in the artistic form it receives the simply human is disclosed with most beauty. The literature of India itself, however, despite all the difficulties attendant on an outlook and artistic expression so alien to our own, is not wholly outside our sympathy; and the boast is no empty one that in our modern era pre-eminently a keen sense for all that art and the human spirit embraces in every direction has begun to unfold itself.
Were we in our present investigation of this impulse toward individualization, pursued so persistently by poetry, under the aspects we have already described, to restrict the same to a _general_ treatment of the art of poetry, such a generalization, however established, could not fail to be abstract and devoid of content. It is therefore of first importance, if our object be to consider poetry of a really genuine type, that we include in our survey the forms of the creative spirit as presented in their national form, the unique product of one age; and further we must not overlook the individuality which creates, the soul of the poet. Such, then, are the main points of view to which I would draw attention by way of a general introduction to poetical creation and conception.
2. THE ART-PRODUCT OF POETRY AND PROSE Poetry is not, however, exhausted by the imaginative idea alone: it must necessarily proceed to make itself articulate and complete in the _poetical work of art._ Such an object of study opens a large field of investigation. We may conveniently arrange and classify the course of our discussion as follows: _First,_ we shall endeavour to point out what is of most importance relatively to the _poetical composition generally._ _Secondly_, we shall distinguish it from the principal types of _prose composition_, in so far as the same are compatible with artistic treatment.
We shall then, _finally_ be in a position to deduce with some completeness the notion of the _free art-product._ (_a_) In respect to the poetical work of art under its generic aspect all that is necessary is once more to enforce our previous contention that it must, no less than any other production of an unfettered imagination, receive the form and independence of an organic whole.
This demand can only receive satisfaction as follows: (_α_) In the _first_ place that which constitutes a homogeneous content, whether it be a definite object of action and event, or a specific emotion and passion, must before everything else possess intrinsic unity.
(_αα_) All else must be posited under relation to this bond of unity, and thereby combine to form a freehand concrete coherence of all parts.
This is only possible under the condition, that the content selected is not conceived as abstract _universal_, but as the action and emotion of men, as the object and passion which are actually present in the mind, soul, and volition of definite individuals, arising as such from the distinctive basis of an individual nature in each case.
(_ββ_) The universal, which is to receive representation, and the individuals, in whose character events and actions the manifestation of poetry is asserted must not consequently fall into fragments, or be so related that the individuals are merely of service as an abstract universal; both aspects must combine in vital coalescence. In the Iliad, for example, the contest of Greeks and Trojans, and the victory of the former is inseparably bound up with the wrath of Achilles, which for this reason becomes the common focus welding all together.
No doubt we also find poetical works in which the fundamental content is partly more abstract in its generalization, and also partly is executed in a way that expresses a universal of more significance.
Dante's great epic poem is an illustration, which not only embraces the world divine throughout, but displays individuals of the most varied character in their relation to the punishments of hell, purgatory and the blessedness of Paradise. But even here we find no entirely abstract separation, of the two points of view, no mere relation of service between the particular objects. For in the Christian world the focus of conscious life is not conceived as nothing more than an accident of Godhead, but as essential and infinite cause or end itself, so that here the universal purpose, that is the divine justice in condemnation and salvation can verily appear as immanent fact, the eternal interest and being of the individual himself. In this divine world the individual is throughout of pre-eminent importance. In that of the State he can of course be sacrificed in order to save the universal, that is the State. In his relation to God, however, and in the kingdom of God he is essentially and exclusively the end.
(_γγ_) We must, however, _thirdly_, conceive the universal, which supplies the content of human emotion and action as self-subsistent, intrinsically complete where it is, and constituting as such in itself a definitive and exclusive world. When, for instance, in our contemporary life mention is made of any officer, official, general, professor, and so forth, and we try to imagine what kind of action such a man or personality is likely to attempt or carry out under his own particular conditions of environment, we place before ourselves simply a content of interest and activity, which in part is not itself a rounded and self-substantive whole, but one which stands in infinitely manifold external connections, relations and conditions, in part also, if we regard it as abstract totality, one which can receive the form of a universal concept in its separation from the individuality of the, in other respects, entire personality, as for instance that of personal obligation. Conversely we may have no doubt a content of sterling character, making, that is to say, an essentially independent whole, which, despite of this, and without further development and advance, is complete in one sentence. It is really impossible to say whether a content of this nature belongs more properly to poetry or prose. The grand affirmation of the old Testament, "God said Let their be Light and there was Light," is at once in its penetration, no less than the precision of its embrace,[7] as much essentially sublime poetry as it is ordinary prose. Of a similar nature is the command, "I am the Lord thy God, thou shalt have no other gods but me"; or that, "Honour thy father and thy mother." The golden epigrams of a Pythagoras and the wise sayings of Solomon are of the same type. Phrases, so rich in content as the above, have their origin in a world where the distinction between poetry and prose is as yet absent. We can, however, hardly affirm of such that they are a poetical work of art, even though many such phrases may be combined together. The independence and rounding off of a genuine poetical work must be assumed at the same time to be of the nature of a process, and a differentiation of parts: we assume it therefore to be a unity, the true character of which is only made explicit by emphatic insistence upon its diversity. This process, absolutely essential in the plastic arts, regarded at least according to the requirements of their form, is also more generally of the greatest moment in a poetical composition.
(_β_) This introduces us, then, to a _second_ feature of the work of art, namely, the organic differentiation of its several parts, essential to it not merely that it may be presented as an organic unity, but that the elaboration of all it implies may be rendered complete.
(_αα_) The most obvious reason of this necessity is referable to the fact that Art in general tends instinctively to particularization.
The effect of the scientific faculty is that what is particular and singular fails to receive its complete vindication. And this is so not merely because the understanding apprehends the manifold, as such theoretic faculty, starting from its principles of generalization, causing the particular fact thereby to evaporate in its abstract deductions and categories; but also because it makes this manifold subserve ends of purely practical import. Severe adherence to that purely relative value, which strictly belongs to the nature of the process, appears to the understanding as useless and tedious. To the conception and composition of poetry on the contrary every part, every phase in the result must remain of essential interest and vital.
It dallies therefore with delight in detail, depicts the same with enthusiasm, and treats every part as an independent whole. However great, therefore, in addition the content may be of a poetical work in its central interest, the organic completeness is equally asserted in subordinate detail, precisely as in the human organism every member, every finger is rounded with exquisite delicacy in its unified completeness, and as a rule, we find in Nature that every particular existence is enclosed within a perfect world of its own. The advance of poetry is therefore more slow than that compatible with the judgments and conclusions of the understanding, where we find that, whether regarded theoretically as science or with reference to practical conduct and action, the main stress is on the final result, this rather than on the path by which it is reached. As for the degree in which poetry approaches realization in its tenderness for such detail we have already pointed out that it is not its vocation to describe with excessive diffuseness what is exterior in the form of its sensuous appearance. If it therefore undertakes extensive descriptions without making them reflect at the same time the claims and interests of soul-life it becomes heavy and tedious. Above all it must take care not to enter into deliberate rivalry with the actual detail, in its exact completeness, presented by natural fact itself. Even painting in this respect should aim at circumspection and restriction. We have therefore here and in the case of poetry a twofold point of view to consider.
On the one hand we must remember that the impression is on our mental vision; and on the other the art can only place before the mind the object, which in Nature we can survey and comprehend in a single glance in a series of separate traits. For this reason it is important that poetry does not carry its elaboration of detail so far, that the vision of the whole in its entirety becomes inevitably disturbed, confused, or lost. It is obvious therefore that difficulties of an exceptional nature have to be overcome when the attempt is made to place an action or event of varied nature before our vision, and where in actual life such happen in a single moment of time, and in close connection with such immediacy, for all it can do is to present the same in a continuous series. As respects this difficulty, no less than the general way in which poetry, as already described, approaches the detail of Nature, we find the demand of the several generic types of the art differs very considerably. Epic poetry, for instance, attaches itself to the particularity of the external world with an emphasis totally different from that of dramatic poetry, with its rapidity of forward movement, or from that of lyrical poetry with its exclusive insistence on the ideally significant.
(_ββ_) It is through an elaboration of this kind that the several parts of a composition secure _subsistency._ No doubt this appears to stand in direct contradiction to the unity which we established as a primary condition: as a matter of fact the opposition is merely apparent.
This independence should not, that is to say, assert itself in such a way that the several parts are placed in absolute separation from each other: it must on the contrary only be carried so far that the several aspects and members of the whole are clearly seen on their own account to be asserted in the vital form peculiar to each, and to stand on their own free basis of independence. If, on the contrary, this individualized life is absent from the several parts, the composition becomes, precisely as Art generally can only invest the universal with determinate existence under the form of actual particularity, cold and defunct.
(_γγ_) Despite of this self-subsistency, however, these several parts must remain likewise in conjunction to the extent that the _one_ fundamental motive or purpose, made explicit and manifest in and through them, must declare itself as the unity which pervades the whole, and in which the parts coalesce and to which they return. This is the condition of art, and pre-eminently so of poetry, where it falls short of its noblest reach, upon which it most readily is wrecked, and the work of art declines from the realm of a free imagination into that of mere prose. To put it in another way, the connexion into which the parts fall must not merely be one of final _cause and effect._ For in the relation of teleology the end is the universal as essentially presupposed and willed, which it is true succeeds in making the several aspects tally with the process, yet employs them none the less as means and to this extent robs them of all really free stability and thereby of every sort of vitality. In such a case the parts merely fall under a relation of purpose to one end, which is asserted imperiously to the disadvantage of all else, and which accepts the same in abstraction as subservient and subordinate to itself. The freedom and beauty of art contradict flatly this servile relation of the abstract faculty of science.
(_γ_) On these grounds the unity, asserted in the several parts of the composition, must be of another character. The definition of this may be stated under two aspects of conception, as follows.
(_αα_) In the _first_ place, the vital presence we have already referred to as peculiar to every part separately must be maintained.
If we direct our attention, however, to that which in fact justifies the introduction of any detail whatever into the composition, we find the point of departure to be _one_ fundamental idea which the same as a whole is undertaken to manifest or interpret. Consequently everything defined and particular must announce that as the source of its own specific appearance. In other words, the content of a poetical work must not be itself intrinsically abstract, but concrete, one that by reason of its own wealth conducts us to a rich unravelment of its varied aspects. And when this variety, even assuming that in its realization it falls to every appearance into plain contradictions, yet is as a matter of fact rooted in the essentially unified content we have adverted to, in that case we may affirm that by necessity the content itself, in a form agreeable to its notion and being, comprises what is fundamentally an exclusive and harmonious totality of particular characteristics, which it possesses as its own, and in the continuous expatiation of which what it is in its real significance is in truth rendered explicit. It is only _these_ several parts, which originally belong to the content, and which consequently should be carried into the composition under the mode of actual and essentially sound and vital existence. In this respect, therefore, despite all appearance the display of particular characteristics present of opposition to others, they are throughout combined in a union of mysterious accord, rooted in its own nature.
(_ββ_) _Secondly,_ since the composition is presented under the form of _natural_ phenomena, the unity must, in order to preserve the vital appearance of such reality, only be the _ideal_ bond, which to all appearance without intention holds together the parts and includes them in an organic whole. It is just this animating union of organic life which alone is able to bring into being true poetry as contrasted with the expressed intention of plain prose. That is to say whenever particularity exclusively appears as means to a definite end, it does not possess and cannot conceivably possess an independent and unique vitality of its own; what it does testify to, on the contrary, is that it exists for the sake of something else, that is the end proposed.
Purpose of this type declares its sovereignty over the objective facts through which it is fulfilled. An artistic composition should, however, confer upon all that is particular within it, all in the expatiation of which it displays continuously the central and fundamental content selected, the appearance of an unfettered stability. This is absolutely necessary, because what we here comprise under the term particularity is just that content itself under the mode of the reality which corresponds with it. We may therefore recall to our minds the analogous task of speculative thought, which in the same way has on the one side to develop the particular to the point of self-subsistency or freedom from that which is at first an indefinite universality; and likewise, too, it is called on to demonstrate how within this totality of what is particular, in which that and that only is divulged which essentially reposes in the universal, the unity is on this very account once more asserted, and indeed then and only then is truly concrete unity, established through its own differences and their mediation.
Speculative philosophy is thus, in the same way, through the method of dialectic above adverted to, responsible for works which resemble in this respect those of poetry, containing, that is, by virtue of the content, an essential identity of self-seclusiveness and a revelation of differentiated material in accord with it. We must, however, despite this similarity between these two activities, and apart from the obvious difference between the evolution of pure thinking and creative art, draw attention to a further essential distinction. The deduction of philosophy no doubt vindicates the necessity and actuality of particularity, but none the less, in virtue of the dialectic process in which this aspect of reality is asserted, it is expressly demonstrated of this particularity and all of it, that it for the first time discovers its truth and its stability in the concrete unity.[8] Poetry, on the contrary, does not proceed to any such express demonstration.
The concordant unity must no doubt be completely vindicated in every one of its creations, and be operative there in all their manifold detail as the soul and vital core of the whole; but this presence remains for Art an ideal bond which is implied rather than expressly posited, precisely as the soul is immediately made vital in all the bodily members, without robbing the same of the appearance of an independent existence. We have the same truth illustrated by colour and tone. Yellow, blue, green and red are different colours which admit
