‘Malebranche,’ says our author, ‘deduces the different manner of thinking and feeling in men and women from the different delicacy of the cerebral fibres. According to our doctrine, certain parts of the brain are more developed in men, others in women; and in that way is the difference of the manifestations of their faculties perfectly explicable.’ Page 105.
For my part, I prefer Malebranche’s solution to the more modern one. It seems to me that the strength or weakness, the pliancy or firmness of the characters of men or women is to be accounted for from something in the general texture of their minds, just as their corporeal strength or weakness, activity or grace is to be accounted for from something in the general texture of their bodies, and not from the arbitrary preponderance of this or that particular limb or muscle. I think the analogy is conclusive against our author. If there is no difference of quality; i.e. of delicacy, firmness, &c. in the parts of the brain ‘more developed in men,’ the difference of quantity alone cannot account for the difference of character. And, on the other hand, if we allow such a difference of quality in the cerebral fibres, or of hardness and softness, flexibility or sluggishness in the whole brain, we shall have no occasion for particular bumps or organs of the brain to account for the difference in the minds of men and women generally. Drs. Gall and Spurzheim seem desirous to set aside all differences of texture, irritability, tenacity, &c. in the composition of the brain, as if these were occult qualities, and to reduce every thing to positive and ostensible quantity; not considering that quantity alone accounts for no difference of character or operation. The increasing the size of the organ of music, for instance, will not qualify that organ to perform the functions of the organ of colour: there must be a natural aptitude in kind, before we talk about the degree or excess of the faculty resulting from the peculiar conformation of a given part. The piling up larger parcels of the same materials of the brain will not produce a new faculty: we must include the nature of the different materials, and it is not too much to assume that whenever the faculty is available to a number of purposes, the difference in the nature of the thinking substance cannot be merely local or organic. For instance, say that the Organ of Memory is distinguished by greater tenaciousness of particles, or by something correspondent to this; that in like manner, the Organ of Fancy is distinguished by greater irritability of structure; is it not better to suppose that the first character pervades the brain of a man remarkable for strong memory, and the last that of another person excelling in fancy, generally and primarily, instead of supposing that the whole retentiveness of the brain is in the first instance lodged in one particular compartment of it, and the whole volatility or liveliness, in the second instance, imprisoned in another hole or corner, with quite as little reason? It may be said, that the organ in question is not an organ of memory in general, but of the memory of some particular thing. Then this will require that there should be an organ of memory of every other particular thing; an organ of invention, and an organ of judgment of the same; which is too much to believe, and besides can be of no use: for unless in addition to these separate organs, over which is written—‘No connexion with the next door’—we have some general organ or faculty, receiving information, comparing ideas, and arranging our volitions, there can be no one homogeneous act or exercise of the understanding, no one art attained, or study engaged in. There will either be a number of detached objects and sensations without a mind to superintend them, or else a number of minds for every distinct object, without any common link of intelligence among themselves. In the first case, each organ would be that of a mere brute instinct, that could never arrive at the dignity of any one art or science, as painting or music; in the second case, no art or science (such as poetry) ever could exist that implied a comparison between any two ideas or the impressions of different organs, as of sight and sound.
Dr. Spurzheim observes, (page 107) ‘The child advances to boyhood, adolescence, and manhood. Then all these faculties manifest the greatest energy. By degrees they begin to decrease; and in the decrepitude of old age, the sensations are blunted, the sentiments weak, and the intellectual faculties almost or entirely suppressed. Hence, as the manifestations of the faculties of the mind and understanding are proportionate to the organization, it is evident that they depend on it.’
I do not see the exact inference meant to be drawn here. All the conditions above enumerated affect the whole brain generally. There is not an organ of youth, of manhood, of decrepitude, &c.
‘A brain too small, however, is always accompanied with imbecility. Willis described the brain of one who was an idiot from birth. It was not more than half the size of an ordinary brain.’ Page 109.
At this rate, if there are idiots by birth, there must be also such a thing as general capacity.
‘I have seen two twin-boys so like each other, that it was almost impossible to distinguish them. Their inclinations and talents presented also a striking and astonishing similitude. Two others, twin-sisters, are very different: in the one the muscular system is the most developed, in the other the nervous. The former is of little understanding, whereas the second is endowed with strong intellectual faculties.’ Page 112.
This is coming to Malebranche’s way of putting the question. In the same page we find the following morceau:—
‘Gaubius relates, that a girl, whose father had killed men in order to eat them, and who was separated from her father in her infancy and carefully educated, committed the same crime. Gaubius drew from this fact the consequence, that the faculties are propagated with the organization.’—Good Gaubius Gobbo! Without believing his fact, we need not dispute his consequence.
‘Malebranche explains the difference of the faculties of both sexes, the various kinds and particular tastes of different nations and individuals, by the firmness and softness, dryness and moisture of the cerebral fibres; and he remarks that our time cannot be better employed than in investigating the material causes of human phenomena. The Cartesians, by their doctrine of the tracks which they admit in the brain, acknowledge the influence of the brain on the intellectual faculties.’ Page 118.
