fittest among innumerable spontaneous variations – but we must at least conclude our glimpse of his pregnant and suggestive work by quoting its great fundamental aperçu: – 'As the earth and ocean were probably peopled with vegetable productions long before the existence of animals, and many families of these animals long before other families of them, shall we conjecture that one and the same kind of living filament is and has been the cause of all organic life?'
A few lines from the 'Temple of Nature,' one of Erasmus Darwin's poetic rhapsodies, containing his fully matured views on the origin of living creatures, may be worth reproduction in further elucidation of his philosophical position: —
'Organic life beneath the shoreless waves
Was born, and nursed in ocean's pearly caves;
First forms minute, unseen by spheric glass.
Move on the mud, or pierce the watery mass;
These, as successive generations bloom,
New powers acquire, and larger limbs assume;
Whence countless groups of vegetation spring,
And breathing realms of fin and feet and wing.'
Have we not here the very beginnings of Charles Darwin? Do we not see, in these profound and fundamental suggestions, not merely hints as to the evolution of evolution, but also as to the evolution of the evolutionist?
On the other hand, though Erasmus Darwin defined a fool to his friend Edgeworth as 'a man who never tried an experiment in his life,' he was wanting himself in the rigorous and patient inductive habit which so strikingly distinguished his grandson Charles. That trait, as we shall presently see, the biological chief of the nineteenth century derived in all probability from another root of his genealogical tree. Erasmus Darwin gave us brilliant suggestions rather than cumulative proof: he apologised in his 'Zoonomia' for 'many conjectures not supported by accurate investigation or conclusive experiments,' Such an apology would have been simply impossible to the painstaking spirit of his grandson Charles.
Erasmus Darwin was twice married. His first wife was Mary, daughter of Mr. Charles Howard, of Lichfield, and it was her son, Robert Waring Darwin, who became the father of our hero, Charles. It is fashionable to say, in this and sundry other like cases, that the mental energy skips a generation. People have said so in the case of that intermediate Mendelssohn who was son of Moses Mendelssohn, the philosopher, and father of Felix Bartholdy Mendelssohn, the composer – that mere link in a marvellous chain who was wont to observe of himself in the decline of life, that in his youth he was called the son of the great Mendelssohn, and in his old age the father of the great Mendelssohn. As a matter of fact, one may fairly doubt whether such a case of actual skipping is ever possible in the nature of things. In the particular instance of Robert Waring Darwin at least we may be pretty sure that the distinctive Darwinian strain of genius lay merely latent rather than dormant: that it did not display itself to the world at large, but that it persisted silently as powerful as ever within the remote recesses of the thinking organism. Not every man brings out before men all that is within him. Robert Waring Darwin was a physician at Shrewsbury; and he attained at least sufficient scientific eminence in his own time to become a Fellow of the Royal Society, in days when that honour was certainly not readily conferred upon country doctors of modest reputation. Charles Darwin says of him plainly, 'He was incomparably the most acute observer whom I ever knew.' It may well have been that Robert Darwin lived and died, as his famous son lived for fifty years of his great life, in comparative silence and learned retirement; for we must never forget that if Charles Darwin had only completed the first half century of his laborious existence, he would have been remembered merely as the author of an entertaining work on the voyage of the 'Beagle,' a plausible theory of coral islands, and a learned monograph on the fossil barnacles. During all those years, in fact, he had really done little else than collect material for the work of his lifetime. If we judge men by outward performance only, we may often be greatly mistaken in our estimates: potentiality is wider than actuality; what a man does is never a certain or extreme criterion of what he can do.
The Darwins, indeed, were all a mighty folk, of varied powers and varied attainments. Erasmus's brother, Robert, was the author of a work on botany, which long enjoyed a respectable repute. Of his sons, one, Sir Francis Darwin, was noted as a keen observer of animals; a second, Charles, who died at twenty-one, was already the author of a very valuable medical essay; while the third, Robert, was the Shrewsbury F.R.S., the father of our great evolutionary thinker. And among Charles Darwin's own cousins, one is Mr. Hensleigh Wedgwood, the philologist; a second was the late Sir Henry Holland; and a third is Mr. Francis Galton, the author of that essentially Darwinian book, 'Hereditary Genius.'
Robert Waring Darwin took to himself a wife from another very great and eminent family. He married Susannah Wedgwood, daughter of Josiah Wedgwood, the famous potter; and from these two silent representatives of powerful stocks, Charles Robert Darwin, the father of modern evolutionary biology, was born at Shrewsbury, on February the 12th, 1809. That Wedgwood connection, again, is no mere casual or unimportant incident in the previous life-history of the Darwinian originality; it throws a separate clear light of its own upon the peculiar and admirably compounded idiosyncrasy of Charles Darwin.
A man, indeed, owes on the average quite as much to his mother's as to his father's family. It is a mere unscientific old-world prejudice which makes us for the most part count ancestry in the direct ascending male line alone, to the complete neglect of the equally important maternal pedigree. Prom the biological point of view, at least, every individual is a highly complex compound of hereditary elements, a resultant of numerous converging forces, a meeting place of two great streams of inheritance, each of which is itself similarly made up by the like confluence of innumerable distinct prior tributaries. Between these two it is almost impossible for us accurately to distribute any given individuality. How much Charles Darwin owed to the Darwins, and how much he owed in turn to the Wedgwoods, no man is yet psychologist enough or physiologist enough to say. But that he owed a great deal to either strong and vigorous strain we may even now quite safely take for granted.
The Wedgwood family were 'throwers' by handicraft, superior artisans long settled at Burslem, in the Staffordshire potteries. Josiah, the youngest of thirteen children, lamed by illness in early life, was turned by this happy accident from his primitive task as a 'thrower' to the more artistic and original work of producing ornamental coloured earthenware. Skilful and indefatigable, of indomitable energy and with great powers of forcing his way in life against all obstacles, young Wedgwood rose rapidly by his own unaided exertions to be a master potter, and a manufacturer of the famous unglazed black porcelain. Those were the darkest days of industrial art and decorative handicraft in modern England. Josiah Wedgwood, by his marked originality and force of character, succeeded in turning the current of national taste, and creating among us a new and distinctly higher type of artistic workmanship. His activity, however, was not confined to his art alone, but found itself a hundred other different outlets in the most varied directions. When his potteries needed enlargement to meet the increased demand, he founded for the hands employed upon his works the model industrial village of Etruria. When Brindley began cutting artificial waterways across the broad face of central England, it was in the great potter that he found his chief ally in promoting the construction of the Grand Trunk Canal. Wedgwood, indeed, was a builder of schools and a maker of roads; a chemist and an artist; a friend of Watt and an employer of Flaxman. In short, like Erasmus Darwin, he possessed that prime essential in the character of genius, an immense underlying stock of energy. And with it there went its best concomitant, the 'infinite capacity for taking pains.' Is it not probable that in their joint descendant, the brilliant but discursive and hazardous genius of Erasmus Darwin was balanced and regulated by soberer qualities inherited directly from the profound industry of the painstaking potter? When later on we find Charles Darwin spending hours in noting the successive movements of the tendrils in a plant, or watching for long years the habits and manners of earthworms in flower-pots, may we not reasonably conjecture that he derived no little share of his extraordinary patience, carefulness, and minuteness of handicraft from his mother's father, Josiah Wedgwood?
