The following remarks can pretend to he nothing more than a few loose and undigested thoughts upon a subject, which has recently occupied the attention of many men, and obtained an extraordinary vogue in the world. It were to be wished, that the task had fallen into the hands of a writer whose studies were more familiar with all the sciences which bear more or less on the topic I propose to consider: but, if abler and more competent men pass it by, I feel disposed to plant myself in the breach, and to offer suggestions which may have the fortune to lead others, better fitted for the office than myself, to engage in the investigation. One advantage I may claim, growing out of my partial deficiency. It is known not to be uncommon for a man to stand too near to the subject of his survey, to allow him to obtain a large view of it in all its bearings. I am no anatomist: I simply take my stand upon the broad ground of the general philosophy of man.
It is a very usual thing for fanciful theories to have their turn amidst the eccentricities of the human mind, and then to be heard of no more. But it is perhaps no ill occupation, now and then, for an impartial observer, to analyse these theories, and attempt to blow away the dust which will occasionally settle on the surface of science. If phrenology, as taught by Gall and Spurzheim, be a truth, I shall probably render a service to that truth, by endeavouring to shew where the edifice stands in need of more solid supports than have yet been assigned to it. If it be a falshood, the sooner it is swept away to the gulph of oblivion the better. Let the inquisitive and the studious fix their minds on more substantial topics, instead of being led away by gaudy and deceitful appearances. The human head, that crowning capital of the column of man, is too interesting a subject, to be the proper theme of every dabbler. And it is obvious, that the professors of this so called discovery, if they be rash and groundless in their assertions, will be in danger of producing momentous errors, of exciting false hopes never destined to be realised, and of visiting with pernicious blasts the opening buds of excellence, at the time when they are most exposed to the chance of destruction.
I shall set out with acknowledging, that there is, as I apprehend, a science in relation to the human head, something like what Plato predicates of the statue hid in a block of marble. It is really contained in the block; but it is only the most consummate sculptor, that can bring it to the eyes of men, and free it from all the incumbrances, which, till he makes application of his art to it, surround the statue, and load it with obscurities and disfigurement. The man, who, without long study and premeditation, rushes in at once, and expects to withdraw the curtain, will only find himself disgraced by the attempt.
There is a passage in an acute writer[39], whose talents singularly fitted him, even when he appeared totally immerged in mummery and trifles, to illustrate the most important truths, that is applicable to the point I am considering.
[39] Sterne, Tristram Shandy, Vol. 1.
"Pray, what was that man's name,--for I write in such a hurry, I have no time to recollect or look for it,--who first made the observation, 'That there was great inconstancy in our air and climate?' Whoever he was, it was a just and good observation in him. But the corollary drawn from it, namely, 'That it is this which has furnished us with such a variety of odd and whimsical characters;'--that was not his;--it was found out by another man, at least a century and a half after him. Then again, that this copious storehouse of original materials is the true and natural cause that our comedies are so much better than those of France, or any others that have or can be wrote upon the continent;--that discovery was not fully made till about the middle of king William's reign, when the great Dryden, in writing one of his long prefaces (if I mistake not), most fortunately hit upon it.
Then, fourthly and lastly, that this strange irregularity in our climate, producing so strange an irregularity in our characters, cloth thereby in some sort make us amends, by giving us somewhat to make us merry with, when the weather will not suffer us to go out of doors,--that observation is my own; and was struck out by me this very rainy day, March 26, 1759, and betwixt the hour of nine and ten in the morning.
"Thus--thus, my fellow-labourers and associates in this great harvest of our learning, now ripening before our eyes; thus it is, by slow steps of casual increase, that our knowledge physical, metaphysical, physiological, polemical, nautical, mathematical, aenigmatical, technical, biographical, romantical, chemical, and obstetrical, with fifty other branches of it, (most of them ending, as these do, in ical,) has, for these two last centuries and more, gradually been creeping upwards towards that acme of their perfections, from which, if we may form a conjecture from the advantages of these last seven years, we cannot possibly be far off."
Nothing can be more true, than the proposition ludicrously illustrated in this passage, that real science is in most instances of slow growth, and that the discoveries which are brought to perfection at once, are greatly exposed to the suspicion of quackery. Like the ephemeron fly, they are born suddenly, and may be expected to die as soon.
