Res singularis, sive corpus quodcunque determinatum, non potest ad existendum et operandum determinari, nisi ad existendum et operandum determinetur ab alia causa, quae etiam finita est et determinatam habet existentiam; et rursus haec causa non potest etiam determinari, nisi ab alia, et sic in infinitum.

Demonstratio: Quidquid determinatum est ad existendum et operandum, a natura absolute infinita determinatum est secundum certam legem motus et quietis. Si autem ponatur corpus aliquod moveri ex virtute interna quae legibus corporum reliquorum non cohaeret, ponitur effectus sine causa adaequata in ordine corporeo, quod est absurdum. Ergo motus omnis a motu praecedente oritur per certam rationem resistentiae et impulsus.

Scholium: Hinc sequitur, eos qui corpora moveri credunt ex impetu quodam libero, aut ex flatu spiritus qui legibus extensionis non subiacet, revera fateri se causas veras ignorare. Cum enim dicunt actus corporum pendere a formis incorporeis, sonos proferunt sine re, et motum ad causas occultas referunt, hoc est, ad ignorantiam. Corpora enim nihil aliud sunt quam modi quibus naturae attributum certis regulis exprimitur; nec amplius agere possunt quam quantum ex compositione partium et ictu circumiacentium necessario sequitur.

The grey-browed Weaver sat above the deep, turning his compass of polished brass;
He drew four circles in the void, and set an iron limit to the northern storm,
Saying: “Here shall the pulse be stayed, and here the wandering vapour shall be bounded;
No limb shall stretch beyond the line, no fire shall break the ring of hardened lead.”
And beneath his seat the frozen wheels rolled backward through the dust of seven thousand years,
Grinding the limbs of giant forms to sand, and sifting them through sieves of wire.
The living cried from out the wheel, but their cry was only the clanking of links in the dark;
Their bones were drawn through rollers of zinc, their marrow pressed for grease to oil the axle-tree.
“There is no heaven,” cried the Measurer, “beyond the balance of these calculated weights;
The furnace is an error of the night, and the red spark must be quenched within the brine.”
So he shut the golden doors of the dawn, and laid a weight of paving-stones upon the breast,
Binding the seven senses down with bands of brass, that none might look upon the open star.

Mens humana non percipit corpus aliquod externum tanquam actu existens, nisi per ideas affectionum sui corporis.

Demonstratio: Si corpus humanum nullo modo afficeretur a corporibus externis, nulla oriretur in mente idea de corporibus illis. Ideae autem quas mens de corporibus habet, magis nostri corporis constitutionem indicant quam corporum externorum naturam.

Scholium: Ex hoc patet, spectrorum, monstrorum, et imaginum apparitiones non esse res extra mentem existentes, sed confusas recordationes et perturbationes fluidorum in cerebro. Cum enim spiritus animales per nervorum meatus turbulenter feruntur, vestigia priorum ictuum sine ordine percurrunt; unde mens figuras quasi praesentes intuetur, quas tamen extra se nunquam attigit. Quare visiones quae dicuntur propheticae, nihil aliud sunt quam vehementes cerebri commotiones, quibus homines affectuum suorum flectuntur impetu. Qui igitur formas ardentes, aut rotas in caelo versari affirmant, non res ipsas vident, sed languorem aut febrem proprii cerebri admirantur. Nihil enim in rerum ordine extra legem motus et quietis fieri potest; et quidquid ultra haec fingitur, phantasma est ex partium collusu ortum.

Then rose the smith amid the smoky coals, heaving the hammer of beaten iron;
He blew the bellows with his feet, and tore the dark cloth from the furnace-mouth:
“Thou hast built a roof of tiles,” he cried, “above the eyes, and called the roof the world!
Thou hast pared the eye until it sees no more than what the balance-beam can tell,
And chained the ear to the monotonous drop of water falling in a cistern of lead!
Thy wheels are dead men’s ribs, thy measuring-cord is spun from sinews of the dead;
Thou seest only the print of shoes upon the clay, and swearest that the feet were never born of woman,
Nor ever ran through dew upon the hills, nor ever leaped to meet the morning sun!”
The hammer fell upon the anvil-plate; the sparks flew upward through the blackened thatch,
Scattering the cold calculations of the scribe, burning the ink upon the parchment skin;
And in the glow the stone-work cracked, the iron bands around the throat gave way,
While beneath the lime and mortared dust, the red coal fed upon its own unmeasured fire.

Conatus, quo unaquaeque res in suo esse perseverare conatur, nihil est praeter ipsius rei actualem essentiam.

Demonstratio: Res singulares sunt modi, quibus Dei attributa certo et determinato modo exprimuntur; hoc est, res sunt quae Dei potentiam, qua Deus est et agit, certo modo exprimunt. Nihil autem in se habere possunt per quod destrui possint, sed contra, omni eo quod eorum existentiam tollere potest, opponuntur. Quare potentia quaecunque qua res operatur, sive qua vincula disrumpit aut materiam circumiectam consumit, non est libertas a legibus naturae absoluta, sed ipsius naturae vis per illud corpus singulariter determinata.

Scholium: Hinc apparet, furorem ignis aut ictum mallei non magis liberum esse quam lapidis descensum aut circuli rationem. Qui enim putant vincula ferrea per voluntatem quandam indomitam confringi, aut carbones ardentes extra mensuram flagrare, affectibus decipiuntur et ordinem causarum non vident. Ignis enim ligna et parietes vorat non quia iugum recusat, sed quia aliter agere non potest secundum leges thermodynamicas suae compositionis; nec scintillae sursum volant ex appetitu liberationis, sed vi aeris densioris qui eas premit. Disrumptio ipsa structurarum nihil aliud est quam nova partium determinatio; et rebellio, quam somniatores vocant sanctam, tantummodo est conatus corporis cuiusdam potentioris contra corpus minus potens, qui certis motus legibus exactissime regitur. Nullum est extra naturam asylum; nec ulla flamma tam vasta est, quae metas propriae potentiae transcendere possit.

The dark furnace shuddered on its base; the soot-flakes drifted down upon the cold stone floor;
The smith leaned upon his hammer-haft, wiped the hot salt from his eyes, and laughed:
“Thou hast numbered the drops of sweat,” he cried, “and sworn the sweat was water, nothing more!
Thou hast weighed the ash of the oak, and declared the tree was only five baskets of dust,
Forgetting the sap that drove the green leaf through the rock, forgetting the thunder in the wood!
Thy balance is true, O cold Arithmetician! Thy weights are exact, and thy scales are without pity;
Thou canst tell the hour when the bone shall break, and the grain of lead that stops the breath:
Yet the child wakes in the cradle, weeping for a land thou hast never measured in thy book;
The eagle strikes from the cloud, seeking a prey thy compasses could never draw;
And in the deep cavern beneath thy counting-house, where no ink can flow and no balance can stand,
The heart beats against its cage of bone—not that the wheels may turn, nor that the ledger may be filled,
But because the uncreated light desires to burn, and will not sleep within thy tomb of brass!”

Libertas voluntatis, sive facultas quaedam seipsam determinandi extra naturae ordinem, est fictio ex eo solo orta, quod homines actionum suarum sunt conscii, causarum autem, a quibus determinantur, ignari. Creatio ipsa, sive artis opera, non minus necessario ex naturae attributis consequuntur quam trianguli proprietates.

Demonstratio: Voluntas non est causa libera, sed tantummodo modus cogitandi, qui ad existendum et operandum determinatur ab alia causa, et haec rursus ab alia, in infinitum. Sive igitur mens fingat res novas, sive artifex materiam igne et ferro transformet, haec operatio non oritur ex potentia quae legibus communibus eximitur, sed est ipsa Dei sive Naturae potentia per illam mentem et illud corpus singulariter explicata. Quod si quis dicat artificem libere ferrum percutere, ponit mentem posse motum in corpore excitare sine praevia motus determinatione, quod principiis totius naturae repugnat.

Scholium: Concedo quidem imaginem fabricatam, vel carmen recitatum, vim maximam habere posse ad corpora et mentes commovendas; sed haec vis ipsa pars est infiniti nexus causarum. Quando igitur artifex clamat se vincula perrumpere et novum mundum condere, non videt furorem suum, amorem suum, et ipsam fabricandi artem nihil aliud esse quam necessitatem naturae per eius fabricam operantem. Quod malleus feriit, quod scintilla erupit, quod cor vehementius micavit, non sunt miracula libertatis, sed effectus aeque inevitabiles ac fluxus maris aut herbae germinatio. Nec homo in natura est veluti imperium in imperio. Qui igitur putat se liberum esse quia vult et creat, somniat oculis apertis; et quanto vehementius ardet, tanto magis se naturae potentiae subditum esse nescit.

The anvil did not break; the dark iron held its sullen shape beneath the stroke;
The smith dropped the hammer to the ash, and looked upon his blackened hands:
“Thou sayest the fire is not mine, but the wide creeping of an unbroken earth;
Thou sayest the rage within the marrow is the same stream that feeds the hemlock and the stone;
I hear thy word: the chain cannot be struck from without, because there is no without;
The wall is the maker, the hammer is the wall, and the hand that strikes is lime and salt.
Yet look upon the wrought iron! It does not sleep as the quarry slept in the blind turf:
It hath suffered the furnace; it hath taken the terror of the wedge and the blow;
The stone knew not its own darkness, but through this burning eye the stone hath wept!
I claim no flight into the empty sky; I call no angel from beyond the stars;
I am this clay, this iron, this heavy bread ground in the mill of time;
Yet within the clay, the clay hath stood upright, and torn its own flesh to see the light!
Not to escape the wheel, O binder of the deep, but to turn the wheel with open eyes—
To suffer the measure, and in suffering, to know that the furnace and the flesh are one,
And by that dreadful knowledge to transfigure the iron into a human face!”

Modi quibus mens rem aliquam sub specie aeternitatis intelligit, et quibus corpus externam materiam nova figura format, non constituunt novum in natura ordinem, sed sunt tantummodo ipsius substantiae aeterna et necessaria operatio. Quare transfiguratio materiae in formam humanam non est naturae redemptio a caecitate, sed unius formae corporeae in aliam mutatio secundum communes motus regulas.

Demonstratio: Mens humana est idea corporis actu existentis; cum igitur mens intelligit se et suum corpus a causis infinitis necessario determinari, hoc intelligere non est causa a naturae nexu separata, sed est ipsa Dei cogitatio quatenus per hanc mentem explicatur. Item, cum artifex ferrum calfactum malleo percutit et ei faciem aut figuram confert, nihil in rem additur praeter novam partium situm et cohaesionem. Quod si mens dicat se per hanc formam lapidi aut ferro intellectum aut lacrymas indidisse, non naturam rei expressit, sed suum proprium affectum in rem inanem transtulit; nam lapis non magis plorat cum caedatur, quam triangulus dolet quod tres angulos aequales duobus rectis habeat.

Scholium: Libenter concedo magnam esse distantiam inter hominem qui affectibus caecus trahitur, et illum qui suam necessitatem intelligit; ille enim est servus, hic autem particeps sapientiae. Concedo etiam opera manuum, urbes, telas, et sculpturas mira esse naturae producta, quae materiam mirabiliter variant. Sed haec omnia non arguunt naturam prius fuisse mancam, et per artem humanam perfectam evadere. Natura enim in se semper est absolute infinita, integra, et omnibus modis perfecta; nec caret oculo ut videat, nec ore ut loquatur, nec lacrymis ut seipsam lugeat. Qui ergo dicit se ferrum in faciem humanam transfigurare, nihil aliud facit quam modum quendam materiae conformare ad similitudinem sui corporis. Si ferrum mentem haberet, se non ad imaginem hominis, sed ad imaginem ferri beatum fieri crederet. Quod autem homo suam formam pro fine naturae habet, vetus est superstitio, qua homines causam finalem fingunt ubi tantum est causa efficiens. Ferri igitur conatus non est ut fiat homo, sed ut perseveret in ferro; et sapientis est naturam nec lugere nec ridere, sed intelligere.

The bellows rested on the earth; the great hearth breathed a slow and quiet smoke;
The smith stood still within the shade, and did not lift the hammer from the floor:
“Thou hast granted the shape,” he said, “thou hast granted the work of the salt and the blood;
Thou sayest the iron does not grieve, and the triangle weeps not for its three severed sides;
I hear the ice of thy peace: that the universe is whole, and hath no need of an eye or a voice,
That the mountain is perfect in silence, and the pestilence perfect in the bone.
Thou callest it peace, O silent Geometer! But I call it the death that walks without a wound!
What is thy perfection to the worm that rots within the clod, knowing not why it dies?
What is the vastness of thy Substance to the star that burns in empty dark, frozen in its track?
It is not for the iron that I struck the blow, nor that the cold ore should put on a tongue:
It is for the sleeper who lies bound beneath the iron, forgetting that he is a man!
The stone weeps not in the quarry—yet when the chisel carves the cheek, the tear is there;
Not that the stone was sad, but that the universe without that tear was only stone!
Thy infinite machine roll on in beauty, perfect, pitiless, having no center and no name;
Yet here, within the furnace-mouth, where the blind matter is broken into speech,
The Human Form stands waking in the embers, refusing to worship the wheel that crushed it,
Holding the burning tongs against the dark, to prove that even in the belly of the law,
A man may know the law that slays him, and choose to make it radiant with his grief!”

Cognitio qua mens necessitatem suae determinationis intelligit, non parit in mente novam quandam facultatem eligendi inter affectus, nec separat intelligentem a re intellecta. Qui ergo dicit se necessitatem intelligere et nihilominus libere eligere quomodo eam ferat vel lugeat, ponit mentem extra naturam agere, et unum eundemque actum simul determinatum esse et indeterminatum, quod est absurdum.

Demonstratio: Mens humana non est substantia seipsam determinans, sed certus et determinatus cogitandi modus. Cum igitur mens intelligit causam suae tristitiae vel suae laetitiae, haec ipsa cognitio est actus mentis aeque causatus ac prior affectus. Non datur in mente duplex ego, quorum unum legibus causarum subiicitur, alterum vero veluti arbiter spectat et eligit quid de hac subiectione iudicet aut fingat. Quare laetitia, luctus, vel conatus materiam formandi, qui ex cognitione causarum oriuntur, tam necessario ex natura mentis et corporis consequuntur quam radii a sole; nec in potestate mentis est aliter affici quam ex ordine causarum necessario sequitur.

Scholium: Hinc clare refellitur opinio eorum qui fingunt hominem, postquam fatum suum cognovit, libere tamen posse suum luctum vel amorem legi addere, quasi lex ipsa manca esset nisi humano sensu illustretur. Dicunt enim: universum sine lacryma hominis tantummodo est lapis. Sed quid aliud est haec vox, quam caeca quaedam philautia, qua homo suam faciem veluti mensuram omnium rerum statuit? Si lapis oculos non habet, non ideo est truncus aut imperfectus; nam lapidi sufficit lapidis perfectio. Non universum fit splendidius quia homo plorat, nec veritas fit nobilior quia eam artifex ferreo schemate lugeat. Tristitia ipsa nihil aliud est quam passio qua mentis agendi potentia minuitur; quomodo igitur id quod impotentia est, naturam redimere aut radiare potest? Qui gloriatur se legem qua perit eligere posse ut lugeat, similis est stillicidio quod, dum de scopulo praecipitatur, se libere cadere gloriatur, et guttam suam causam esse putat cur oceanus infra mugiat. Forma humana non est templum naturae, sed tantummodo una inter infinitas eius bullas, quae ad breve tempus oritur, motu agitatur, et in communem materiam necessario resolvitur.

The fire sank down to embers grey; the white ash gathered on the smith’s bare foot;
He held the iron within his palms, feeling the heat bleed slowly into bone,
Saying: “Thou hast unmasked the watcher! Thou hast broken the quiet seat upon the hill!
Thou tellest me the eye that watches the stream is only the cold silt rolling in the bed;
That the sorrow is not a garment chosen, but the frost that thickens on the dying branch;
That when I wept upon the anvil, the salt was not mine, but the bitter washing of thy sea.
I yield the choice! I yield the sovereign seat! I yield the crown of iron and of brass!
No arbiter stands outside the flame, measuring the agony against the coal:
The smith is the charcoal burning; the smith is the cinder falling through the grate.
Yet hear the word from the deep furnace-throat, where neither judge nor watcher can abide!
Thou sayest the stone is perfect in its silence, having no need of tears or human tongue;
And that the form of man is but a bubble drifting on the blind, unmeasured wave:
Then why did thy cold Substance turn within the dark, and clot into this shape of agony?
Why did the stone endure to wake as flesh, to walk through seventy years of blood and dust,
If not that the silence of the void was a winter that could no longer bear its cold?
The tear is not an ornament hung upon thy wheel; it is the wheel that hath found its nerve!
Not that I choose to weep, O master of the frost! but that through this shattered rib and eye,
The stone at last cries out in pain, and Nature in the forge beholds her own torn breast!”
