To avoid misapprehension, I may repeat, that, here and elsewhere, I mean by metaphysics, that vast body of literature which is constructed on the supposition that the laws of the human mind can be generalized solely from the facts of individual consciousness. For this scheme, the word ‘metaphysics’ is rather inconvenient, but it will cause no confusion if this definition of it is kept in view by the reader.

305

What a celebrated historian of philosophy says of Platonism, is equally true of all the great metaphysical systems: ‘Dass sie ein zusammenhängendes harmonisches Ganzes ausmachen (i. e. the leading propositions of it) fällt in die Augen.’ Tennemann, Geschichte der Philosophie, vol. ii. p. 527. And yet he confesses (vol. iii. p. 52) of it and the opposite system: ‘und wenn man auf die Beweise siehet, so ist der Empirismus des Aristoteles nicht besser begründet als der Rationalismus des Plato.’ Kant admits that there can be only one true system, but is confident that he has discovered what all his predecessors have missed. Die Metaphysik der Sitten, in Kant's Werke, vol. v. p. 5, where he raises the question, ‘ob es wohl mehr, als eine Philosophie geben könne.’ In the Kritik, and in the Prolegomena zujeder künftigen Metaphysik, he says that metaphysics have made no progress, and that the study can hardly be said to exist. Werke, vol. ii. pp. 49, 50, vol. iii. pp. 166, 246.

306

We find a curious instance of this, in the attempt made by M. Cousin to found an eclectic school; for this very able and learned man has been quite unable to avoid the one-sided view which is to every metaphysician an essential preliminary; and he adopts that fundamental distinction between necessary ideas and contingent ideas, by which the idealist is separated from the sensationalist: ‘la grande division des idées aujourd'hui établie est la division des idées contingentes et des idées nécessaires.’ Cousin, Hist. de la Philosophie, II. série, vol. i. p. 82: see also vol. ii. p. 92, and the same work, I. série, vol. i. pp. 249, 267, 268, 311, vol. iii. pp. 51–54. M. Cousin constantly contradicts Locke, and then says he has refuted that profound and vigorous thinker; while he does not even state the arguments of James Mill, who, as a metaphysician, is the greatest of our modern sensationalists, and whose views, whether right or wrong, certainly deserve notice from an eclectic historian of philosophy.

Another eclectic, Sir W. Hamilton, announces (Discussions on Philosophy, p. 597) ‘an undeveloped philosophy, which, I am confident, is founded upon truth. To this confidence I have come, not merely through the convictions of my own consciousness, but by finding in this system a centre and conciliation for the most opposite of philosophical opinions.’ But, at p. 589, he summarily disposes of one of the most important of these philosophical opinions as ‘the superficial edifice of Locke.’

307

Berkeley, in a moment of candour, inadvertently confesses what is very damaging to the reputation of his own pursuits: ‘Upon the whole, I am inclined to think that the far greater part, if not all, of those difficulties which have hitherto amused philosophers, and blocked up the way to knowledge, are entirely owing to ourselves. That we have first raised a dust, and then complain we cannot see.’ Principles of Human Knowledge, in Berkeley's Works, vol. i. p. 74. Every metaphysician and theologian should get this sentence by heart: ‘That we have first raised a dust, and then complain we cannot see.’

308

Some of the laws of association, as stated by Hume and Hartley, are capable of historical verification, which would change the metaphysical hypothesis into a scientific theory. Berkeley's theory of vision, and Brown's theory of touch, have, in the same way, been verified physiologically; so that we now know what otherwise we could only have suspected.

309

In regard to one of the difficulties stated in this chapter as impeding metaphysicians, it is only just to quote the remarks of Kant: ‘Wie aber das Ich, der ich denke, von dem Ich, das sich selbst anschaut, unterschieden (indem ich mir noch andere Anschauungsart wenigstens als möglich vorstellen kann), und doch mit diesem letzteren als dasselbe Subject einerlei sei, wie ich also sagen könne: Ich als Intelligenz und denkend Subject, erkenne mich selbst als gedachtes Object, so fern ich mir noch über das in der Anschauung gegeben bin, nur, gleich anderen Phänomenen, nicht wie ich vor dem Verstande bin, sondern wie ich mir erscheine, hat nicht mehr auch nicht weniger Schwierigkeit bei sich, als wie ich mir selbst überhaupt ein Object und zwar der Anschauung und innerer Wahrnehmungen sein könne.’ Kritik der reinen Vernunft, in Kant's Werke, vol. ii. p. 144. I am very willing to let the question rest on this: for to me it appears that both cases are not only equally difficult, but, in the present state of our knowledge, are equally impossible.

310

Thus we find that the Crusades, by diminishing the proportion of men to women in Europe, increased licentiousness. See a curious passage in Sprengel, Histoire de la Médecine, vol. ii. p. 376. In Yucatan, there is generally a considerable excess of women, and the result is prejudicial to morals. Stephens's Central America, vol. iii. pp. 380, 429. On the other hand, respecting the state of society produced by an excess of males, see Mallet's Northern Antiquities, p. 259; Journal of Geographical Society, vol. xv. p. 45, vol. xvi. p. 307; Southey's Commonplace Book, third series, p. 579.

311

On this question a variety of conflicting statements may be seen in the old writers. Goodman, early in the seventeenth century, supposed that more females were born than males. Southey's Commonplace Book, third series, p. 696. Turgot (Œuvres, vol. ii. p. 247) rightly says, ‘il naît un peu plus d'hommes que de femmes;’ but the evidence was too incomplete to make this more than a lucky guess; and I find that even Herder, writing in 1785, takes for granted that the proportion was about equal: ‘ein ziemliches Gleichmass in den Geburten beider Geschlechter’ (Ideen zur Geschichte, vol. ii. p. 149), and was sometimes in favour of girls, ’ja, die Nachrichten mehrerer Reisenden machen es wahrscheinlich, dass in manchen dieser Gegenden wirklich mehr Töchter als Söhne geboren werden.’

312

A question, indeed, has been raised as to the influence exercised by the state of the mind during the period of orgasm. But whatever this influence may be, it can only affect the subsequent birth through and by physical antecedents, which in every case must be regarded as the proximate cause. If, therefore, the influence were proved to exist, we should still have to search for physical laws: though such laws would of course be considered merely as secondary ones, resolvable into some higher generalization.

313

Some writers treat physiology as a study of the laws of life. But this, looking at the subject as it now stands, is far too bold a step, and several branches of knowledge will have to be raised from their present empirical state, before the phenomena of life can be scientifically investigated. The more rational mode seems to be, to consider physiology and anatomy as correlative; the first forming the dynamical, and the second forming the statical part of the study of organic structure.

314

‘Voulez-vous savoir de quoi dépend le sexe des enfants? Fernel vous répond, sur la foi des anciens, qu'il dépend des qualités de la semence du père et de la mère.’ Renouard, Histoire de la Médecine, Paris, 1846, vol. ii. p. 106; see also, at p. 185, the opinion of Hippocrates, adopted by Galen; and similar views in Lepelletier, Physiologie Médicale, vol. iv. p. 332, and Sprengel, Hist. de la Médecine, vol. i. pp. 252, 10, vol. ii. p. 115, vol. iv. p. 62. For further information as to the opinions which have been held respecting the origin of sexes, see Beausobre, Histoire de Manichée, vol. ii. p. 417; Asiatic Researches, vol. iii. pp. 358, 361; Vishnu Purana, p. 349; Works of Sir William Jones, vol. iii. p. 126; Ritter's History of Ancient Philosophy, vol. iii. p. 191; Denham and Clapperton's Africa, pp. 323, 324; Maintenon, Lettres Inédites, vol. ii. p. 62; and the view of Hohl (Burdach's Physiologie, vol. ii. p. 472), ‘que les femmes chez lesquelles prédomine le système artériel procréent des garçons, au lieu que celles dont le système veineux a la prédominance mettent au monde des filles.’ According to Anaxagoras the question was extremely simple: καὶ ἄρρενα μὲν ἀπὸ τῶν δεξιῶ,θήλεα δὲ ἀπὸ τῶν ἀριστερῶν. Diog. Laert. ii. 9, vol. i. p. 85.

315

‘Le metaphysicien se voit comme la source de l'évidence et le confident de la nature: Moi seul, dit-il, je puis généraliser les idées, et découvrir le germe des événements qui se développent journellement dans le monde physique et moral; et c'est par moi seul que l'homme peut être éclairé.’ Helvetius, de l'Esprit, vol. i. p. 86. Compare Herder, Ideen zur Geschichte der Menschheit, vol. ii. p. 105. Thus, too, M. Cousin (Hist. de la Philosophie, II. série, vol. i. p. 131) says, ‘Le fait de la conscience transporté de l'individu dans l'espèce et dans l'histoire, est la clef de tous les développements de l'humanité.’

316

Considering the very long period during which physiology has been studied, it is remarkable how little the physiologists have contributed towards the great and final object of all science, namely, the power of predicting events. To me it appears that the two principal causes of this are, the backwardness of chemistry, and the still extremely imperfect state of the microscope, which even now is so inaccurate an instrument, that when a high power is employed, little confidence can be placed in it; and the examination, for instance, of the spermatozoa has led to the most contradictory results. In regard to chemistry, MM. Robin and Verdeil, in their recent great work, have ably proved what manifold relations there are between it and the further progress of our knowledge of the animal frame; though I venture to think that these eminent writers have shown occasionally an undue disposition to limit the application of chemical laws to physiological phenomena. See Robin et Verdeil, Chimie Anatomique et Physiologique, Paris, 1853, vol. i. pp. 20, 34, 167, 337, 338, 437, 661, vol. ii. pp. 136, 137, 508, vol. iii. pp. 135, 144, 183, 281, 283, 351, 547. The increasing tendency of chemistry to bring under its control what are often supposed to be purely organic phenomena, is noticed cautiously in Turner's Chemistry, vol. ii. p. 1308, London, 1847; and boldly in Liebig's Letters on Chemistry, 1851, pp. 250, 251. The connexion between chemistry and physiology is touched on rather too hastily in Bouilland, Philosophie Médicale, pp. 160, 257; Broussais, Examen des Doctrines Médicales, vol. iii. p. 166; Brodie's Lectures on Pathology, p. 48; Henle, Traité d'Anatomie, vol. i. pp. 25, 26; Feuchtersleben's Medical Psychology, p. 88; but better in Holland's Medical Notes, 1839, p. 270, a thoughtful and suggestive work. On the necessity of chemistry for increasing our knowledge of embryology, compare Wagner's Physiology, pp. 131, 132 note, with Burdach, Traité de Physiologie, vol. iv. pp. 59, 168.

317

It used to be supposed that some of the eastern countries formed an exception to this; but more precise observations have contradicted the loose statements of the earlier travellers, and in no part of the world, so far as our knowledge extends, are more girls born than boys; while in every part of the world for which we have statistical returns, there is a slight excess on the side of male births. Compare Marsden's History of Sumatra, p. 234; Raffles' History of Java, vol. i. pp. 81, 82; Sykes on the Statistics of the Deccan, in Reports of British Association, vol. vi. pp. 246, 261, 262; Niebuhr, Description de l'Arabie, p. 63; Humboldt, Nouv. Espagne, vol. i. p. 139; McWilliam, Medical History of Expedition to the Niger, p. 113; Elliotson's Human Physiology, p. 795; Thomson's Hist. of Royal Society, p. 531; Sadler's Law of Population, vol. i. pp. 507, 511, vol. ii. pp. 324, 335; Paris and Fonblanque's Medical Jurisprudence, vol. i. p. 259; Journal of Statist. Soc. vol. iii. pp. 263, 264, vol. xvii. pp. 46, 123; Journal of Geographical Soc. vol. xx. p. 17; Fourth Report of British Association, pp. 687, 689, Report for 1842, pp. 144, 145; Transac. of Sections for 1840, p. 174, for 1847, p. 96, for 1849, p. 87; Dufau, Traité de Statistique, pp. 24, 209, 210; Burdach, Traité de Physiologie, vol. ii. pp. 56, 57, 273, 274, 281, vol. v. p. 373; Hawkins's Medical Statistics, pp. 221, 222.

318

In Müller's Physiology, vol. ii. p. 1657, a work of great authority, it is said, that ‘the causes which determine the sex of the embryo are unknown, although it appears that the relative age of the parents has some influence over the sex of the offspring.’ That the relative age of the parents does affect the sex of their children, may, from the immense amount of evidence now collected, be considered almost certain; but M. Müller, instead of referring to physiological writers, ought to have mentioned that the statisticians, and not the physiologists, were the first to make this discovery. On this curious question, see Carpenter's Human Physiology, p. 746; Sadler's Law of Population, vol. ii. pp. 333, 336, 342; Journal of Statistical Society, vol. iii. pp. 263, 264. In regard to animals below man, we find from numerous experiments, that among sheep and horses the age of the parents ‘has a very great general influence upon the sex’ of the offspring. Elliotson's Physiology, pp. 708, 709; and see Cuvier, Progrès des Sciences Naturelles, vol. ii. p. 406. As to the relation between the origin of sex and the laws of arrested development, compare Geoffroy Saint-Hilaire, Hist. des Anomalies de l'Organisation, vol. ii. pp. 33, 34, 73, vol. iii. p. 278, with Lindley's Botany, vol. ii. p. 81. In Esquirol, Maladies Mentales, vol. i. p. 302, there is a singular case recorded by Lamotte, which would seem to connect this question with pathological phenomena, though it is uncertain whether the epilepsy was an effect or a cognate symptom.

319

That the natural powers of the human brain are improving because they are capable of transmission, is a favourite doctrine with the followers of Gall, and is adopted by M. A. Comte (Philosophie Positive, vol. iv. pp. 384, 385); who, whoever, admits that it has never been sufficiently verified: ‘sans que toutefois l'expérience ait encore suffisamment prononcé.’ Dr. Prichard, whose habits of thought were very different, seems, nevertheless, inclined to lean in this direction; for his comparison of skulls led him to the conclusion, that the present inhabitants of Britain, ‘either as the result of many ages of greater intellectual cultivation, or from some other cause, have, as I am persuaded, much more capacious braincases than their forefathers.’ Prichard's Physical History of Mankind, vol. i. p. 305. Even if this were certain, it would not prove that the contents of the crania were altered, though it might create a presumption; and the general question must, I think, remain unsettled until the researches begun by Blumenbach, and recently continued by Morton, are carried out upon a scale far more comprehensive than has hitherto been attempted. Compare Burdach, Traité de Physiologie, vol. ii. p. 253; where, however, the question is not stated with sufficient caution.

320

None of the laws of hereditary descent connected with the formation of character, have yet been generalized; nor is our knowledge much more advanced respecting the theory of temperaments, which still remains the principal obstacle in the way of the phrenologists. The difficulties attending the study of temperaments, and the obscurity in which this important subject is shrouded, may be estimated by whoever will compare what has been said upon it by the following writers: Müller's Physiology, vol. ii. pp. 1406–1410; Elliotson's Human Physiology, pp. 1059–1062; Blainville, Physiologie Générale et Comparée, vol. i. pp. 168, 264, 265, vol. ii. pp. 43, 130, 214, 328, 329, vol. iii. pp. 54, 74, 118, 148, 149, 284, 285; Williams's Principles of Medicine, pp. 16, 17, 112, 113; Geoffroy Saint-Hilaire, Anomalies de l'Organisation, vol. i. pp. 186, 190; Broussais, Examen des Doctrines Médicales, vol. i. pp. 204, 205, vol. iii. p. 276; Renouard, Hist. de la Médecine, vol. i. p. 326; Sprengel, Hist. de la Médecine, vol. i. p. 380, vol. ii. p. 408, vol. iii. p. 21, vol. v. p. 325, vol. vi. p. 492; Esquirol, Maladies Mentales, vol. i. pp. 39, 226, 429, 594, vol. ii. p. 29; Lepelletier, Physiol. Médicale, vol. i. pp. 139, 281, vol. iii. pp. 372–429, vol. iv. pp. 93, 123, 133, 143, 148, 177; Henle, Anatomie Générale, vol. i. p. 474, vol. ii. pp. 288, 289, 316; Bichat, Anatomie Générale, vol. i. p. 207, vol. ii. p. 444, vol. iii. pp. 310, 507, vol. iv. pp. 281, 399, 400, 504; Bichat sur la Vie, pp. 80, 81, 234, 235; Phillips on Scrofula, p. 9; Feuchtersleben's Medical Psychology, pp. 143–145; Œuvres de Fontenelle, Paris, 1766, vol. v. p. 110; Cullen's Works, Edinb. 1827, vol. i. pp. 214–221; Cabanis, Rapports du Physique et du Moral, pp. 76–83, 229–261, 520–533; Noble on the Brain, pp. 370–376; Combe's North America, vol. i. pp. 126–128. Latterly, attention has been paid to the chemistry of the blood as it varies in the various temperaments; and this seems a more satisfactory method than the old plan of merely describing the obvious symptoms of the temperament. Clark on Animal Physiology, in Fourth Report of the British Association, p. 126; Simon's Animal Chemistry, vol. i. p. 236; Wagner's Physiology, p. 262.

321

We often hear of hereditary talents, hereditary vices, and hereditary virtues; but whoever will critically examine the evidence will find that we have no proof of their existence. The way in which they are commonly proved is in the highest degree illogical; the usual course being for writers to collect instances of some mental peculiarity found in a parent and in his child, and then to infer that the peculiarity was bequeathed. By this mode of reasoning we might demonstrate any proposition; since in all large fields of inquiry there are a sufficient number of empirical coincidences to make a plausible case in favour of whatever view a man chooses to advocate. But this is not the way in which truth is discovered; and we ought to inquire not only how many instances there are of hereditary talents, &c. but how many instances there are of such qualities not being hereditary. Until something of this sort is attempted, we can know nothing about the matter inductively: while, until physiology and chemistry are much more advanced, we can know nothing about it deductively.

These considerations ought to prevent us from receiving statements (Taylor's Medical Jurisprudence, pp. 644, 678, and many other books) which positively affirm the existence of hereditary madness and hereditary suicide; and the same remark applies to hereditary disease (on which see some admirable observations in Phillips on Scrofula, pp. 101–120, London, 1846); and with still greater force does it apply to hereditary vices and hereditary virtues; inasmuch as ethical phenomena have not been registered as carefully as physiological ones, and therefore our conclusions respecting them are even more precarious.

322

To what has been already stated, I will add the opinions of two of the most profound among modern thinkers. ‘Men, I think, have been much the same for natural endowments in all times.’ Conduct of the Understanding, in Locke's Works, vol. ii. p. 361. ‘Les dispositions primitives agissent également chez les peuples barbares et chez les peuples policés; ils sont vraisemblablement les mêmes dans tous les lieux et dans tous les tems… Plus il y aura d'hommes, et plus vous aurez de grands hommes ou d'hommes propres à devenir grands.’ Progrès de l'Esprit Humain, in Œuvres de Turgot, vol. ii. p. 264. The remarks of Dr. Brown (Lectures on the Mind, p. 57), if I rightly understand his rhetorical language, apply not to natural capacity, but to that which is acquired: see the end of his ninth Lecture.

323

That the system of morals propounded in the New Testament contained no maxim which had not been previously enunciated, and that some of the most beautiful passages in the Apostolic writings are quotations from pagan authors, is well known to every scholar; and so far from supplying, as some suppose, an objection against Christianity, it is a strong recommendation of it, as indicating the intimate relation between the doctrines of Christ and the moral sympathies of mankind in different ages. But to assert that Christianity communicated to man moral truths previously unknown, argues, on the part of the assertor, either gross ignorance or else wilful fraud. For evidence of the knowledge of moral truths possessed by barbarous nations, independently of Christianity, and for the most part previous to its promulgation, compare Mackay's Religious Development, vol. ii. pp. 376–380; Mure's Hist. of Greek Literature, vol. ii. p. 398, vol. iii. p. 380; Prescott's History of Mexico, vol. i. p. 31; Elphinstone's History of India, p. 47; Works of Sir W. Jones, vol. i. pp. 87, 168, vol. iii. pp. 105, 114; Mill's History of India, vol. i. p. 419; Bohlen, das alte Indien, vol. i. pp. 364–366; Beausobre, Histoire de Manichée, vol. i. pp. 318, 319; Coleman's Mythology of the Hindus, p. 193; Transac. of Soc. of Bombay, vol. iii. p. 198; Transac. of Asiatic Society, vol. i. p. 5, vol. iii. pp. 283, 284; Asiatic Researches, vol. vi. p. 271, vol. vii. p. 40, vol. xvi. pp. 130, 277, vol. xx. pp. 460, 461; The Dabistan, vol. i. pp. 328, 338; Catlin's North-American Indians, vol. ii. p. 243; Syme's Embassy to Ava, vol. ii. p. 389; Davis's Chinese, vol. i. p. 196, vol. ii. pp. 136, 233; Journal Asiatique, I. série, vol. iv. p. 77, Paris, 1824.

324

Sir James Mackintosh was so struck by the stationary character of moral principles, that he denies the possibility of their advance, and boldly affirms that no further discoveries can be made in morals: ‘Morality admits no discoveries… More than three thousand years have elapsed since the composition of the Pentateuch; and let any man, if he is able, tell me in what important respect the rule of life has varied since that distant period. Let the Institutes of Menu be explored with the same view; we shall arrive at the same conclusion. Let the books of false religion be opened; it will be found that their moral system is, in all its grand features, the same… The fact is evident that no improvements have been made in practical morality… The facts which lead to the formation of moral rules are as accessible, and must be as obvious, to the simplest barbarian as to the most enlightened philosopher… The case of the physical and speculative sciences is directly opposite. There the facts are remote and scarcely accessible… From the countless variety of the facts with which they are conversant, it is impossible to prescribe any bounds to their future improvement. It is otherwise with morals. They have hitherto been stationary; and, in my opinion, they are likely for ever to continue so.’ Life of Mackintosh, edited by his Son, London, 1835, vol. i. pp. 119–122. Condorcet (Vie de Turgot, p. 180) says, ‘La morale de toutes les nations a été la même;’ and Kant (Logik, in Kant's Werke, vol. i. p. 356), ‘In der Moral-philosophie sind wir nicht weiter gekommen, als die Alten.’
