What is truth?

‘Appearance…constitutes the actuality and the movement of the life of truth. The True is thus the Bacchanalian revel in which no member is not drunk; yet because each member collapses as soon as he drops out, the revel is just as much transparent and simple repose. Judged in the court of this movement, the single shapes of Spirit do not persist any more than determinate thoughts do, but they are as much positive and necessary moments, as they are negative and evanescent.’

Hegel’s Rose of ‘Reason’ on the Rosicrucian Cross

‘To comprehend what is, this is the task of philosophy, because what is, is reason. …To recognise reason as the rose in the cross of the present and thereby to enjoy the present, this is the rational insight which reconciles us to the actual, the reconciliation which philosophy affords to those in whom there has once arisen an inner voice bidding them to comprehend…’

‘Now, because it has only phenomenal knowledge for its object, this exposition seems not to be Science, free and self-moving in its own peculiar shape; yet from this standpoint it can be regarded as the path of the natural consciousness which presses forward to true knowledge; or as the way of the Soul which journeys through the series of its own configurations as though they were the stations appointed for it by its own nature, so that it may purify itself for the life of the Spirit, and achieve finally, through a completed experience of itself, the awareness of what it really is in itself.’

Hegel and Nicholas of Cusa – part five

What Hegel read but never acknowledged and what all the academics missed. Why?

09.12.13

From Johann Gottlieb Buhle, Geschichte der neuern Philosophie seit der Epoche der Wiederherstellung der Wissenschaften, in six volumes, Johann Georg Rosenbusch, Göttingen, 1800, volume 2

pp. 341-353 continued

De sapientia, a work in three books, is a commentary on De coniecturis. It is in dialogue form, an imitation of the similarly titled dialogue of Petrarch.1 A Layman and an Orator (professor of rhetoric) meet in the Roman Forum; the former scoffs at scholastic learning, the latter defends it. The author makes a third person, describing the external setting of the dialogue. In the third book a fourth person makes his appearance, a renowned philosopher from outside Rome, present there for the Jubilee, whom the Orator meets by chance. Nicholas, speaking in the person of the Layman, presents in a popular form his theory of the numbers as the beginnings of knowledge. He begins with the observation that the people in the Roman Forum are counting money, weighing goods, measuring out commodities. How are they able to do this, he asks the Orator. And he proceeds to expound his philosophical system of numbers in its application to God, the world, and the soul. These dialogues demonstrate once again that the gift of setting out philosophical concepts in a comprehensible, popular manner was one utterly denied to Nicholas. Before long the Layman is speaking in such mathematically mystical terms that the Orator would be fully justified in throwing back at him the rebukes he himself suffered for his scholastic learning at the beginning of the dialogue. How much more appropriate and interesting is the Petrarchian dialogue that Nicholas is seeking to imitate! That Nicholas gives himself the role of the Layman is not so much due to contempt for scholastic learning, which Petrarch indeed shared, but to Nicholas’ desire to present his philosophy as one of non-knowing, as merely the outcome of speculation, as he called it, and thus opposed to the supposititious knowledge of the rhetoricians and philosophers of his time; for the renowned foreign philosopher too is brought by the Orator to the Layman and has to submit to his teaching.

Tomb in S.Pietro in Vincoli, Rome, with the relief ‘Cardinal Nicholas before St Peter’ by Andrea Bregno

Nicholas deals in particular with the numbers as the most appropriate signs of the nature of objects in a treatise of which the compendium has been transcribed;2 as he further expounds his theology in the treatises De visione Dei (On the vision of God), De Dato Patris luminum (On the gift of the Father of lights), De quaerendo Deum (On seeking God), De venatione sapientiae (On seeking for wisdom), and De apice theoriae (On the Summit of Contemplation).3 These last treatises differ from the aforementioned in being even more thickly interwoven with Alexandrine mysticism; in them Nicholas adopts much of the mystical theological enthusiasm of Dionysius the Areopagite, one of his favourite authors (as he is of most philosophers of the Middle Ages as well as of Nicholas’ own day), whom he follows almost without reserve. Nicholas further shows himself a fiery zealot on behalf of Christian Catholicism against the Muslims and the Bohemian Hussites. In a separate work he undertakes a comparison of Christianity with the religion of Mohammed,4 proves the Koran a forgery, and defends Christianity against the reproaches of the Moorish philosophers, in some cases from passages of the Koran itself. The Bohemians or Hussites are the target of four Epistles. His remaining works are concerned with mathematics, astronomy and physics.5

Notes

1. The opening of the dialogue is just like Petrarch’s, except that the Layman and the Orator, as the author notes, go to a barber shop to continue their philosophical discussion undisturbed (Vol. 1, fol. 75). I would draw attention to the following passage of the dialogue: ORATOR. Quomodo ductus esse potes ad scientiam ignorantiae tuae, cum sis Idiota? IDIOTA. Non ex tuis, sed Dei libris. O. Qui sunt illi? I. Quos suo digito scripsit. O. Ubi reperiuntur? I. Ubique. O. Igitur et in hoc foro. I. Immo etiam dixi, quod sapientia clamat in plateis. O. Optarem audire quomodo? I. Si te absque curiosa inquisitione affectum conspicerem, magna tibi panderem. O. Potesne hoc brevi tempore efficere, ut qui(d) velis degustem? (ORATOR: Since you are a Layman, how are you able to be led to a knowledge of your ignorance? LAYMAN: Not from your books but from God’s books. O.: Which books are they? L.: Those that He wrote with his finger. O.: Where are they found? L.: Everywhere. O.: Therefore, even in this Forum? L.: Yes, indeed! I have already said that wisdom proclaims itself in the streets. O.: I would like to hear how it does so. L.: If I saw that you were not motivated by idle curiosity, I would disclose to you important matters. O. Can you at this moment bring it about that I sense what you mean?) — We see that the Layman speaks as the scholar ought to speak, and the scholar as the Layman ought to. In Petrarch the converse is the case. In the second book or dialogue the Rhetorician goes looking for the Layman, finds him circa templum aeternitatis (near the Temple of Eternity), and the conversation resumes. In the third dialogue the Rhetorician meets the Philosopher, a stranger, on a bridge over the Tiber and takes him to the Layman, who is carving wooden spoons in the basement of a house. The Layman is of the opinion that if the stranger is a true philosopher he will not despise his occupation. The Philosopher replies that Plato too is said to have painted now and then.—Nicholas appends to each dialogue the time it took to complete. The first was written in one day in July 1465, the second in two days in early August, and the third and longest near the end of August.

The world is maximality contracted or made finite, and the diversity of things arises from the differing kinds and degrees of contraction of maximality.1 However, in order to understand the maximum in its relation to the world, we must first, as Nicholas expresses it, have purged our understanding of all concepts of circles and spheres. It will then be found that it is not the most perfect body, like the sphere; nor a plane figure, like the circle or triangle; nor a straight line; but is raised above all of these, as it is above everything that can be comprehended by the senses, the imagination and the reason with material attributes. The maximum is the simplest and most abstract understanding; it contains all things and one; the line is at once triangle, circle and sphere; oneness is trinity and conversely; accident is substance; the body is mind; motion is rest etc. But unless we realise that the oneness of God must necessarily be a trinity as well, we have not yet completely purged our understanding of concepts of mathematical figures. Nicholas demonstrates this by an example borrowed from human understanding. The oneness of human understanding is nothing else than that which understands, that which is understandable, and the act of understanding. If we wish to ascend from that which understands to the maximum (that which understands infinitely), without adding that this is at once also the highest understandable and the highest act of understanding, we will not have a correct concept of the greatest and most perfect oneness.2 Nicholas applies the concept of the trinity of the primal maximum to the world as well, which as an image of that maximum must also express a threeness. This threeness of the universe manifests itself (1) in the mere possibility thereof or the primal material, (2) in the form, and (3) in the world soul or world spirit, which inheres in all things as well as in the whole. The

primal maximum also expresses the contracted maximum; creator and creation are one.3 Nicholas believed (missing words in German text – I am drawing attention to the fact that the German sentence is incomplete: its construction does not ‘add up’. The intended meaning is something like ‘N. believed one/he could find in the contracted maximum…the principal kinds of worldly creatures…’ Trans.) in the contracted maximum and its relation to the divine the principal kinds of worldly creatures, which differ in their degree of perfection, as Ficino had assumed. He too placed man on the intermediate level, as a link between the lower, lifeless organic and animal world on the one hand and the world of the angels and the divine on the other. But in these premises he also found—as Ficino had not—the explanation of the mystery of the incarnation of god as man. God wished to raise his work, the essence of creation, to perfection, and this could only be done by himself becoming a creature (created thing). As this creature he chose man, because man occupies the middle position in the order of worldly beings and is therefore the bond of his connection with the whole. God, who exists omnipresent in all things, assumed physical humanity and could do so without coming into contradiction with his own being; for considered absolutely, creator and creation are in any case one.4

2. Ibid. Book I, ch. 10. Oportet philosophiam, ad trinitatis notitiam ascendere volentem, circulos et spheras evomuisse. Ostensum est in prioribus unicum simplicissimum maximum; et quod ipsum tale non fit nec perfectissima figura corporalis, ut est sphera, aut superficialis, ut est circulus, aut rectilinealis, ut est triangulus, aut simplicis rectitudinis, ut est linea. Sed ipsum super omnia illa est. Itaque illa, quae aut per sensum, aut imaginationem aut rationem cum naturalibus appendiciis attinguntur, necessario evomere oportet, ut ad simplicissimam et abstractissimam intelligentiam perveniamus, ubi omnia sunt unum; ubi linea sit triangulus, circulus, et sphera; ubi unitas sit trinitas, et e converso; ubi accidens sit substantia; ubi corpus sit spiritus; motus fit quies et caetera huiusmodi. Et tunc intelligitur, quando quodlibet in ipso uno intelligitur unum, et ipsum unum omnia, Et per consequens quodlibet in ipso omnia. Et non recte evomuisti spheram, circulum, et huiusmodi, si non intelligis, ipsum unitatem maximam necessario esse trinam. Maxima enim nequaquam recte intelligi poterit, si non intelligatur trina. Ut exemplis at hoc utamur convenientibus: Videmus unitatem intellectus non aliud esse, quam Intelligens, Intelligibile et Intelligere. Si igitur ab eo, quod est Intelligens, velis te ad maximum transferre et dicere, maximum esse maxime Intelligens, et non adiicias, ipsum etiam esse maxime Intelligibile et maxime Intelligere; non recte de unitate maxima et perfectissima concipis. (Philosophy, desiring to ascend unto a knowledge of this Trinity, must leave behind circles and spheres. In the preceding I have shown the sole and very simple Maximum. And I have shown that the following are not this Maximum: the most perfect corporeal figure (viz., the sphere), the most perfect surface figure (viz., the triangle), the most perfect figure of simple straightness (viz., the line). Rather, the Maximum itself is beyond all these things. Consequently, we must leave behind the things which, together with their material associations, are attained through the senses, through the imagination, or through reason—so that we may arrive at the most simple and most abstract understanding, where all things are one, where a line is a triangle, a circle, and a sphere, where oneness is threeness (and conversely) where accident is substances, where body is mind, where motion is rest, and other such things. Now, there is understanding when (1) anything whatsoever in the One is understood to be the One, and the One (is understood to be) all things, and consequently, (2) anything whatsoever in the One (is understood to be) all things. And you have not rightly left behind the sphere, the circle, and the like, unless you understand that maximal Oneness is necessarily trine—since maximal Oneness cannot at all be rightly understood unless it is understood to be trine. To use examples suitable to the foregoing point: We see that oneness of understanding is not anything other than that which understands, that which is understandable, and the act of understanding. So suppose you want to transfer your reflection from that which understands to the Maximum and to say that the Maximum is, most greatly, that which understands; but suppose you do not add that the Maximum is also, most greatly, that which is understandable, together with being the greatest actual understanding. In that case, you do not rightly conceive of the greatest and most perfect Oneness.)

Another ardent anti-scholastic was Nicholas from Cusel [Cusa in Latin], a village in the district of Trier (Treves), where he was born in the early fifteenth century. He so distinguished himself by his brilliance, erudition and taste that he was made a doctor of theology, bishop of Brixen, and also a cardinal. In his De docta ignorantia praecisionis veritatis inattingibilis (On learned ignorance of the unattainability of exact truth) he attacked in particular the craze of the scholastics for debating any subject even if it utterly transcended the bounds of human reason. In his own philosophising he was closer to a skeptical attitude. In another work, De coniecturis (On speculation), he declared that any human proposition with real content was no more than a probable assumption. He also dealt with more particular metaphysical questions in other works.

pp. 341-353

The history of the Platonists of the fourteenth and fifteenth centuries, as described up to now, contains far more that is worthy of note than that of those of their contemporaries who were true Aristotelians. The latter were for the most part mere Latin translators of and commentators on Aristotle’s writings. What was particular to them, such as George of Trebizond, Gennadius Georgius Scholarius etc. in their dispute with the Platonists, has already been mentioned in the historical discussion of this dispute, where I also touched on the most important circumstances of their lives.

Nicholas of Cusa (1401-1464), detail of relief ‘Cardinal Nicholas before St. Peter’ on his tomb by Andrea Bregno, church of St. Peter in Chains, Rome

More attention is due to Cardinal Nicholas of Cusa, not so much as a true Aristotelian, but as an original writer who had educated himself by the methods of Aristotelian philosophy. He had primarily occupied himself with the study of mathematics and hence applied his mathematical concepts to metaphysical subjects, in particular theology. But his mathematical concepts are just as incomprehensible in themselves as is his metaphysical application of them, and for this reason Nicholas of Cusa’s philosophy, insofar as it is original, might be termed a kind of mathematical mysticism. Apart from writings specifically devoted to mathematics and theology, his most important philosophical works are the following: De docta ignorantia liber I (On learned ignorance [three books]); Apologia doctae ignorantiae liber I (Defence of learned ignorance [one book]); De coniecturis libri duo (On speculation [two books]); De sapientia libri III (On wisdom [three books]).1 The contents of the first of these are quite different from what one would expect from its title. A metaphysic is constructed on the idea of the absolute maximum, which is simultaneously absolute oneness, from which Nicholas ultimately seeks to explain also the positive dogmatics of religion and the mysteries of the Trinity and the Redemption. The docta ignorantia (learned ignorance) consists in the recognition that the absolute maximum or absolute oneness is unknowable per se, because all knowledge must be mediated through a number, yet this maximum is greater than any number. Hence the result of this recognition is a learned ignorance.2 Nicholas does not here undertake to investigate how we attain to the idea of the maximum or absolute oneness; he merely assumes that it is presupposed by all men and is the end of their rational endeavour. Only an imperfect, symbolic knowledge of the maximum is possible; the symbol is drawn from mathematics. The maximum is absolute oneness and thus coincides with the minimum; it is absolutely necessary, eternal, and the eternal foundation of the world.3 It passes first into the Trinity. The maximum as absolute Oneness is God; this oneness repeats itself or begets equality with itself (the divine Son), and the union of oneness with its equality constitutes the third person of the divinity (the Holy Spirit). Ab unitate gignitur unitatis aequalitas; connexio vero ab unitate procedit et ab unitatis aequalitate.4 (Equality of oneness is begotten from oneness, but union proceeds from oneness and from equality of oneness.)

Notes

1. Besides the above-mentioned edition of the works of Nicholaus of Cusa (Basel 1565, 3 folio volumes), two other editions exist. The first was published in Germany, probably at Basel, and is lacking several of Nicholas’ works. See Hamberger’s Nachrichten von den vornehmsten Schriftstellern, vol. IV, P. 768. The second is more complete. As the dedicatory letter shows, it was prepared by Jacob Faber of Estaples. Its description reads: Haec accurata recognitio trium voluminum operum clarissimi P. Nicolai Cusae Card. ex officina Ascensiana recenter emissa est; cuius universalem indicem proxime sequens pagina monstrat. Vaenundantur cum caeteris eius operibus in aedibus Ascensianis; III Voll. fol. (This careful revision of three volumes of the works of the famous Cardinal Nicholas of Cusa, was recently issued by the Ascensian Press, of which a complete catalogue appears on the next page. They are available together with the rest of his works from the Ascensian Publishing House; Three folio volumes), with no indication of the year and place of printing. At the end of De mathematica perfectione (On mathematical perfection) in volume 3 there is a note that the entire collection was printed at Paris in 1514. To this work in volume 3 is appended the De concordantia catholica (On Catholic concordance). This edition is the one I have before me.

4. Nicholas also expresses this as follows: Quemadmodum generatio unitatis ab unitate est una unitatis repetitio; ita processio ab utroque est repetitionis illius unitatis, sive mavis dicere, unitatis et aequalitatis unitatis ipsius unitio. Ibid. Book II, ch. 6. Vol. I fol. 4. (Just as generation of oneness is one repetition of oneness, so the procession from both is oneness of the repetition of this oneness—or, if you prefer the expression – is oneness of oneness and of the equality of this oneness. [Trans. The reference is incorrect, which is the reason I was at first unable to identify this quote: the source is De docta ignorantia, Book I, ch. 9])

Plato, the poet, inspiration and change

Raphael’s imagining of Plato and Aristotle, The School of Athens, fresco, 1509-11, Apostolic Palace, Vatican City

Plato believed that art is essentially mimetic and used ‘mimesis’ in different ways to express what the product of a craftsman is on a scale of diminishing degrees of reality and knowledge (from knowledge [pure thought and reason] to opinion [belief and illusion]), in relation to the true objects of knowledge – the Forms. Using the example of a bed: the eidos of Bed, made by the god is a unique, eternal and unchanging and therefore fully real essence, embodied in all beds.

A bed made by a carpenter participates in the essence of Bed, but because it is in the world of change, is less real. An artist’s painting of the bed is a mere image or illusion because it is only of the appearance of the bed – the bed painted from one perspective, as though seen in a mirror – so the painting is thrice removed from true reality and knowledge. Similarly, the mimesis produced by the poet (who creates pictures with words) is the re-presentation of life – mere imitation.

While an artist can paint a bit and bridle he does not understand the form that is proper to these objects, he has neither knowledge nor correct belief of what he depicts because he has no experience of them. The smith and leather-worker can make them – but even they don’t have the understanding of them that the horseman has. As with the soul, the tripartite Platonic divisions apply in the arts: here – the art of use, the art of making and the art of representation. The implied equation between ‘art of use’ and (knowledge of) eternal reality is on the basis of ‘complete engagement with’ – developed in Neoplatonism. The poet is the counterpart of the painter – their work too is thrice removed from reality, for the same reasons. The poet knows nothing more than their own craft – how to re-present appearances. They have no knowledge on the basis of experience of what they write about but employ their mere imagination.

Plato held that the only poetry that should be allowed in the commonwealth is that which praises the gods and ‘good’ men. He had particular hostility to ‘imitative’ poetry because it was to this that the Greeks had traditionally looked for moral and intellectual guidance (his prime target was Homer). He wanted to establish philosophy as that sole source, denying not only the parallels between poetry and philosophy – that they were both art forms that could be literary and pedagogical, but also the cognitive potential of poetry and the arts. He believed that ‘wisdom’ could be gained not through the study of the poet’s portraits of heroes but only through rigorous dialectic.

He argued that whereas (his) philosophy had as its summum bonum true knowledge on the basis of reason’s engagement with what was most real through strict training, the poet’s (particularly tragic) aim was to appeal to the ‘non-rational’ part of the soul and the arousal of emotion in their audience, on the basis of the poet’s imitation of appearances. The experience of the emotions aroused would then carry over into the daily lives of the citizens, to their detriment.

What was particularly threatening to Plato (because of his sensitivity to and capacity for inspiration and his determination to deny lived emotions and change with his controlled, rationalist system, and whom Guthrie correctly described as a philosophical theologian) was that the poet is ‘divinely inspired’. Poets work from inspiration not (linguistic) reason, they don’t understand the meaning of their language, they present a semblance of life with no grasp of reality. Such poetry, like all art, is play and not to be taken seriously. Thus Plato argued that the poet should be not allowed into a just commonwealth ‘because he stimulates and strengthens an element which threatens to undermine the reason.’

Driven by his antipathy to change and his incapacity to accept its necessity and by the manifestation of this in his division and opposition between ‘reason’ and ‘emotions’, Plato banished from his republic (from what was in effect his model for the perfection of self) that which, as evidenced by his own writing, he had the deepest appreciation of – poetry – and those whose business it was – including, by implication and most particularly, himself.
