ON THE CULTIVATION OF GEOMETRY IN LANCASHIRE.

If our Queries on this subject be productive of no other result than that

of eliciting the able and judicious analysis subsequently given by MR.

WILKINSON (Vol. ii., p. 57.), they will have been of no ordinary utility.

The silent early progress of any strong, moral, social, or intellectual

phenomenon amongst a large mass of people, is always difficult to trace:

for it is not thought worthy of record at the time, and before it becomes

so distinctly marked as to attract attention, even tradition has for the

most part died away. It then becomes a work of great difficulty, from the

few scattered indications in print (the books themselves being often so

rare[1] that "money will not purchase them"), with perhaps here and there a

stray letter, or a metamorphosed tradition, to offer even a probable

account of the circumstances. It requires not only an intimate knowledge of

the subject-matter which forms the groundwork of the inquiry, both in its

antecedent and cotemporary states, and likewise in its most improved state

at the present time; it also requires an analytical mind of no ordinary

powers, to separate the necessary from the probable; and these again from

the irrelevant and merely collateral.

MR. WILKINSON has shown himself to possess so many of the qualities

_essential_ to the historian of mathematical science, that we trust he will

continue his valuable researches in this direction still further.

It cannot be doubted that MR. WILKINSON has traced with singular acumen the

manner in which the _spirit_ of geometrical research was diffused amongst

the operative classes, and the class immediately above them--the exciseman

and the country schoolmaster. Still it is not to be inferred, that even

these classes did not contain a considerable number of able geometers

anterior to the period embraced in his discussion. The Mathematical Society

of Spitalfields existed more than half a century before the Oldham Society

was formed. The sameness of pursuit, combined with the sameness of

employment, would rather lead us to infer that geometry was _transplanted_

from Spitalfields to Manchester or Oldham. Simpson found his way from the

country to London; and some other Simpson as great as Thomas (though less

favourably looked upon by fortune in furnishing stimulus and opportunity)

might have migrated from London to Oldham. Or, again, some Lancashire

weaver might have adventured to London (a very common case with country

artisans after the expiration of apprenticeship); and, there having

acquired a taste for mathematics, as well as improvement in his mechanical

skill, have returned into the country, and diffused the knowledge and the

tastes he took home with him amongst his fellows. The very name betokens

Jeremiah Ainsworth to have been of a Lancashire family.

But was Ainsworth really the earliest mathematician of his district? Or,

was he merely the first that made any figure in print as a correspondent of

the mathematical periodicals of that day? This question is worthy of MR.

WILKINSON's further inquiry; and probably some light may be thrown upon it

by a careful examination of the _original_ Ladies' and Gentleman's Diaries

of the period. In the reprints of these works, only the names, real or

assumed, of those whose contributions were actually printed, are

inserted--not the list of all correspondents.

Now one would be led to suppose that the study of mathematics was

peculiarly suited to the daily mode of life and occupation of these men.

Their employment was monotonous; their life sedentary; and their minds were

left perfectly free from any _contemplative_ purpose they might choose.

Algebraic investigation required writing: but the weaver's hands being

engaged he could not write. A diagram, on the contrary, might lie before

him, and be carefully studied, whilst his hands and feet may be performing

their functions with an accuracy almost instinctive. Nay more: an

exceedingly complicated diagram which has grown up gradually as the result

of investigations successively {437} made, may be carried in the memory and

become the subject of successful peripatetic contemplation. On this point a

decided _experimental_ opinion is here expressed: but were further

instances asked for, they may be found in Stewart, Monge, and Chasles, all

of whom possessed this power in an eminent degree. Indeed, without it, all

attempts to study the geometry of space (even the very elements of

descriptive geometry, to say nothing of the more recondite investigations

of the science) would be entirely unproductive. It is, moreover, a power

capable of being acquired by men of average intellect without extreme

difficulty; and that even to the extent of "mentally seeing" the

constituent parts of figures which have never been exhibited to the eye

either by drawings or models.

That such men, if once imbued with a love for geometry, and having once got

over the drudgery of elementary acquisition, should be favourably situated

for its cultivation, follows as a matter of course. The great difficulty

lay in finding sufficient stimulus for their ambition, good models for

their imitation, and adequate facilities for publishing the results at

which they had arrived. The admirable history of the contents of their

scanty libraries, given by MR. WILKINSON, leaves nothing more to be said on

that head; except, perhaps, that he attributes rather more to the

_influences_ of Emerson's writings than I am able to do.[2] As regards

their facilities for publication, these were few, the periods of

publication being rarely shorter than annual; and amongst so many

competitors, the space which could be allotted to each (even to "the best

men") was extremely limited. Yet, contracted as the means of publication

were, the spirit of emulation did something; from the belief that

_insertion was an admitted test of superiority_, it was as much an object

of ambition amongst these men to solve the "prize question" as it was by

philosophers of higher social standing to gain the "prize" conferred by the

_Académie des Sciences_, or any other continental society under the wing of

Royalty, at the same period. The prize (half a dozen or a dozen copies of

the work itself) was not less an object of triumph, than a Copley or a

Royal medal is in our own time amongst the philosophers of the Royal

Society.

These men, from similarity of employment and inevitable contiguity of

position, were brought into intercourse almost of necessity, and the

formation of a little society (such as the "Oldham") the natural

result--the older and more experienced men taking the lead in it. At the

same time, there can be little doubt that the Spitalfields Society was the

pattern after which it was formed; and there can be as little doubt that

one or more of its founders had resided in London, and "wrought" in the

metropolitan workshops. Could the records of the "Mathematical Society of

London" (now in the archives of the Royal Astronomical Society) be

carefully examined, some light might be thrown upon this question. A list

of members attending every weekly meeting, as well as of visitors, was

always kept; and these lists (I have been informed) have been carefully

preserved. No doubt any one interested in the question would, upon

application to the secretary (Professor De Morgan), obtain ready access to

these documents.

The preceding remarks will, in some degree, furnish the elements of an

answer to the inquiry, "_Why_ did geometrical speculation take so much

deeper root amongst the Lancashire weavers, than amongst any other classes

of artisans?" The subject was better adapted to the weaver's mechanical

life than any other that could be named; for even the other favourite

subjects, botany and entomology, required the suspension of their proper

employment at the loom. The formation of the Oldham Society was calculated

to keep alive the aspiration for distinction, as well as to introduce

novices into the arcanium of geometry. There was generous co-operation, and

there was keen competition,--the sure stimulants to eminent success. The

unadulterated love of any intellectual pursuit, apart from the love of fame

or the hope of emolument, is a rare quality in all stages of society. Few

men, however, seem to have realised Basil Montagu's idea of being governed

by "a love of _excellence_ rather than the pride of _excelling_," so

closely as the Lancashire geometers of that period--uncultivated as was the

age in which they lived, rude as was the society in which their lives were

passed, and selfish as the brutal treatment received in those days by

mechanics from their employers, was calculated to render them. They were

surrounded, enveloped, by the worst social and moral influences; yet, so

far as can now be gathered from isolated remarks in the periodicals of the

time, they may be held up as a pattern worthy of the imitation of the

philosophers of our own time in respect to the generosity and strict honour

which marked their intercourse with one another.

Mathematicians seldom grow up solitarily in any locality. When _one_

arises, the absence of all external and social incentives to the study can

only betoken an inherent propensity and constitutional fitness for it. Such

a man is too much in earnest to keep his knowledge to himself, or to wish

to stand alone. He makes disciples,--he aids, encourages, guides them. His

own researches are fully communicated; and this with a prodigality

proportioned to his own great resources. He feels no jealousy of

competition, and is always gratified by seeing others successful. Thus such

bodies of men are created in wonderfully short periods by the magnanimous

labours of one ardent {438} spirit. These are the men that found societies,

schools, sects; wherever one unselfish and earnest man settles down, there

we invariably find a cluster of students of his subject, that often lasts

for ages. Take, for instance, Leeds. There we see that John Ryley created,

at a later period, the Yorkshire school of geometers; comprising amongst

its members such men as Swale, Whitley, Ryley ("Sam"), Gawthorp, Settle,

and John Baines. This, too, was in a district in many respects very

analogous to Lancashire, but especially in the one to which the argument

more immediately relates:--it was a district of weavers, only substituting

wool for cotton, as cotton had in the other case been substituted for the

silk of Spitalfields.

We see nothing like this in the agricultural districts; neither do we in

those districts where the ordinary manufacturing operations themselves

require the employment of the head as well as the hands and feet. With the

exception, indeed, of the schoolmaster, and the exciseman, and the

surveyor, there are comparatively few instances of persons whose employment

was not strictly sedentary having devoted their intellectual energies to

mathematics, independent of early cultivation. To them the subject was more

or less professional, and their devotion to it was to be expected--indeed

far more than has been realised. It is professional now to a larger and

more varied class of men, and of course there is a stronger body of

non-academic mathematicians now than at any former period. At the same time

it may be doubted whether there be even as many really able men devoted to

science purely and for its own sake in this country as there were a century

ago, when science wore a more humble guise.

Combining what is here said with the masterly analysis which MR. WILKINSON

has given of the books which were accessible to these men, it appears that

we shall be able to form a correct view on the subject of the Lancashire

geometers. Of course documentary evidence would be desirable--it would

certainly be interesting too.

To such of your readers as have not seen the mathematical periodicals of

that period, the materials for which were furnished by these men, it may be

sufficient to state that the "NOTES AND QUERIES" is conceived in the exact

spirit of those works. The chief difference, besides the usual

subject-matter, consists in the greater formality and "stiffness" of those

than of this; arising, however, of necessity out of the specific and rigid

character of mathematical research in itself, and the more limited range of

subjects that were open to discussion.

The one great defect of the researches of those men was, that they were

conducted in a manner so desultory, and that the subjects themselves were

often so isolated, that there can seldom be made out more than a few

dislocated fragments of any one subject of inquiry whatever. Special

inquiries are prosecuted with great vigour and acumen; but we look in vain

for system, classification, or general principles. This, however, is not to

be charged to _them_ as a scientific vice, peculiarly:--for, in truth, it

must be confessed to be a vice, not only too common, but almost universal

amongst English geometers; and even in the geometry of the Greeks

themselves, the great object appears to have been "problem-solving" rather

than the deduction and arrangement of scientific truths. The modern French

geometers have, however, broken this spell; and it is not too much too hope

that we shall not be long ere we join them in the development of the

systems they have already opened; and, moreover, add to the list some

independent topics of our own. The chief dangers to which we are in this

case exposed are, classification with incomplete data, and drawing

inferences upon trust. It cannot be denied, at all events, that some of our

French cotemporaries have fallen into both these errors; but the abuse of a

principle is no argument for our not using it, though its existence (or

even possible existence) should be a strong incentive to caution.

These remarks have taken a more general form than it is usual to give in

your pages. As, however, it is probable that many of your readers may feel

an interest in a general statement of a very curious intellectual

phenomenon, I am not without a hope that, though so far removed from the

usual topics discussed in the work, they will not be altogether

unacceptable or useless.
