[25] See concerning this the above-named work by Hj. Holmquist, in which he says p. 223 concerning Swedenborg’s method of research: Swedenborg himself indicates the scientific method which he followed: first, the collecting of as many experiments and investigations as possible, afterwards the working over of these according to the laws of geometry, and lastly, speculation, hypotheses: ’as long as proofs are lacking, principles may not be accepted and hypotheses defended, as they then deserve better the name of fantasies than of principles’. ’Experientia, geometria et facultas ratiocinandi’, experience, geometry and reason, were the foundations of Swedenborg’s work both within the world of nature and that of spirit.

[30] As observed in Quain’s Elements of Anatomy, Tenth edition, edit. by E. A. SchÄfer and G. D. Thane, Vol. III., Part.

III., No. 127, fin., and No. 404, where we read as follows: Ex anatome Cerebri id constat, quod Cerebrum, seu substantia ejus corticalis, quae proprie cerebrum audit, sit Sensorium commune, nam quinque organa suos sensus externos ad corticem ut ad suum sensorium commune et unicum internum referunt. Cerebrum corticale etiam est Motorium commune voluntarium, quicquid enim agendum est mediantibus nervis et musculis, id praevia voluntate a cerebro determinandum est.

[33] Œc. R. A. II., 107: Partes hujus substantiae — — — merentur Organa Sensuum interiorum et Cerebellula nuncupari, nam media substantia medullari et sanguine ab Organis externis alluentes modos et tactus recipiunt, et ad judicem animam referunt. See also Œc. R. A. 191, 192, Œc. R. A. II., 195: — — Substantiae Corticales totidem sunt Cerebellula, — —; singula enim sensorium est in particulari, quale est Cerebrum in communi.

[34] Œc. R. A. II., 193: Haec minime effectum consequerentur, — — — nisi partes substantiae Corticalis inter se, atque in gradus et series sint divisae, in quales sunt modificationum causae: seu nisi series substantiarum corticalium sint uti series sensationum; nisi sphaerularum Corticis perfectissima sit varietas harmonica, ita ut nulla earum, praeter qua essentialia et attributa, alteri sit simillima. For the same see also Regnum Animale, VII., chap. XX; Œc. R. A. II., No. 307: Ex lustratione ipsius Cerebri apparet, quod substantiae corticales ita Sapienter sunt ordinatae, ut cuilibet sensationi externae ad amussim correspondeant; nam dictae substantiae, ut unitates glomatim in quendam numerum coalescunt, et hi glomuli tanquam novae unitates in congeries adhuc majores, et hae in maximam, quae est ipsum Cerebrum: singulae partitiones discriminatae sunt per rimas, sulcos et anfractus, et consertae per vasa et productiones meningeas, sic ut quasi sint numeri unitatum in analogiae formam redacti, prorsus ut decet sensorium commune, quod recepturum sit omnem speciem sensationis externae, distinctim suum visum, distinctim auditum, gustum et olfactum.

And III., 59, 127, at the end, and 197.

[39] Œc. R. A. II., No. 147: Sphaerulae illum sortitae sunt in Cerebro ordinem et situm, ut singulae aut plures simul, aut omnes in communi queant systolen suam et diastolen perficere. Œc. R. A. II., No. 156: Quare ita compaginatum est Cerebrum, ut totum queat alterna vertigine auferri, utque solum ejus medietas aut semiglobi Haemisphaerium; aut solum plures aut una circumgyratio; aut utmodo hujus glomus, minor congeries, aut pars. The same in The Brain, No. 104 c.

[40] Œc. R. A. I., No. 505: Ergo inquirendum venit, qui tori corticei his aut illis musculis in Corpore correspondent; quod fieri non potest nisi per experientiam in vivis Animalibus; per punctiones, sectiones et compressiones plurium, perque inde in Corporis musculis redundantes effectus.

[41] Œc. R. A. II. Nos. 151, 157: — — — licet ipsa fibra Cerebri non agat motricem in musculis, agit tamen in utraque illa Medulla, quarum fibras ad sic non aliter agendum disponit, uti ab Anatomia Cerebri tam humani, quam animalium brutorum, imo insectorum, clare colligitur: idque ob rationem, ut Cerebri Voluntarium abeat in spontaneum et naturale mediis Medullis, ne toties in particulares profundas motiones auferatur, quoties actio semel incepta ex consueto continuanda sit; id ejus sublimiorum officiorum administrationem toties alias interturbaret, et in Homine analyses rationales, quae quietiorem Cerebri statum poscunt: quare ut primum actio voluntaria poscit seriem agendorum continuam, Cerebrum annuet et consentiet, tum et actionis actualitatem producet: Sic ejus est causa principalis, Medullis autem incineratis injuncta secundaria. See also I., No. 574:—origo secundaria vel causa intermedia actionum Voluntariarum in Spontaneas abeuntium sit in Medulla Spinali et oblongata.

[43] Œc. R. A. II., No. 159: Id jam extra omnem dubitationis aleam ponimus, quod substantia corticalis sit determinans, licet non omnium primum, actionum Corporis, quia determinans est fibrarum, et fibrae musculorum, a quibus actio. — — — II., No. 160: Sed hae substantiae corticales licet sunt determinantes actionum sui Corporis, respective tamen sunt modo subdeterminantes et mediantes, quibus respondent subdeterminantes in Corpore, quae sunt fibrae motrices. See also II., No. 204.

[44] Œc. R. A. II., No. 277: — — — dicere quod Anima sit supra mentem intellectualem, — — — See also II., No. 280. II., No. 160: Per illas (substantias corticales) etenim determinatur in actum voluntas, cujus principium altius est rimandum. — — — requiritur vis altior, sublimior, principalior, et universalior, in qua sit principium voluntatis, qua his mediis determinatur in actum. Proinde est fluidum spirituosum, in quo est vita, et proinde anima.

[45] Œc. R. A. II., 285: Ex his jam sequitur, quod Anima sit, quae intelligit, cogitat, judicat, vult, desiderat, imaginatur, cupit, reminiscitur, videt, audit, gustat, odorat, sentit, loquitur, agit, — — —. See also II., 287.

[46] Œc. R. A. II., No. 160, 161: Et haec denique concludit, quod sit anima, quae huic fluido (spirituoso) inest, cujus est determinare in actum. II., 165. II., 303: Ipsum Fluidum Spirituosum est substantia eminenter organica suae Animae; uti Oculus est organum visus, Auris auditus, Lingua gustus, Cerebrum perceptionis omnium; etc. See also The Brain, No. 7.

[47] See for example Œc. R. A. II., No. 246: — — — sic etiam quod hoc Fluidum sit Spiritus et Anima sui Corporis. — — — Œc. R. A. III., No. 317: Anima est purissima essentia animalis, caelestis et spiritualis, quae fibram simplicem excitat et simul sanguinem tam candidum quam rubrum ingreditur.

[48] See also Œc. R. A. II., No. 348: Ex his jam praemissis usque ad fidem intellectus demonstrari potest, quod Fluidum Spirituosum humanum immunissimum sit ab omni injuria contingentium in regione sublunari; nec exstinguibile, sed immortale, tametsi non per se, post casum sui Corporis. Quod exsolutum a vinculis et laqueis terrestrium in omnem sui Corporis formam coaliturum sit et victurum vitam omni imaginatione puriorem. Tum quod nulla sit actiuncula ex consulto, et nulla vocula ex consensu, in vita ejus corporea, edita, quae non affulgente luce sapientiae, inhaerenter designatae, tunc ante ejus conscientiae judicium, distincte compariturae sint.

[73] These lobes are, as he says, marked out and encompassed by the carotid artery, a statement by which he probably means the same as Ridley, when the latter says of the whole anterior region that it is marked out, as it were, by two branches of the carotid artery, one at the front and one at the side, i. e., Arteria cerebri anterior and Arteria cerebri media.

A., III., No. 127: Si enim vivum corticem in apertis cerebris lente microscopica, sive delineatum ex vivo contemplamur, evidenter conspicitur, quomodo fibra ex illo procedat, et tanquam rivulus ex fonticulo scaturiat; id etiam in hydrocephalis, apoplecticis, catalepticis, paralyticis, maniacis, motibus convulsivis et spasmis cynicis vexatis confirmatur, nam ipsa labes substantiÆ eorum corticalis post mortem deprehensa in continuas fibras, et tandem in musculares, unde prodeunt actiones et inconcinni motus, derivatur. — — — Ergo, quia substantia corticalis est parens fibrarum, sequitur, quod cerebrum non nisi quam in hac sua substantia incipiat cerebrum esse, quatenus ibi est receptaculum sensationum seu sensorium commune, et simul principium actionum, seu motorium commune.

[87] See Œc. R. A., II., No. 156: Vitiato uno cerebellulo aut pluribus in toto, contagium se non latius quam in appensas fibras et subjectos musculos immediate extendat.
