2. After an unattached couple of years, during which he continued his self-education, experimented, invented, and meditated, there began a period of miscellaneous literary work, of journalism, and essay-writing, during which he wrote his Principles of Psychology and felt his way to his System (1848-1860).
3. At the age of forty, he settled down to something like unity of occupation—developing and writing The Synthetic Philosophy (1860-1882).
4. Finally, during a prolonged period of pronounced invalidism, he withdrew almost completely from social life, husbanding his meagre supply of mental energy for the completion of his System, the revision of his works, and his Autobiography (1882-1903).
Engineering.—For about ten years (1837-46) Herbert Spencer had a varied experience of practical life. He began as assistant, at £80 a year, to Mr Charles Fox, who had been one of Mr George Spencer's pupils,—a man of mechanical genius, who was at that time resident engineer of the London division of the "London and Birmingham" railway, and afterwards became well known as the designer and constructor of the Exhibition-Building of 1851. Spencer had surveying and measuring, drawing and calculating to do, and he threw off the slackness which marked his school-days. During the first six months in London he never went to any place of amusement and never read a novel, but gave his leisure to mathematical questions and to suggesting little inventions or improved methods.
A transference for the summer months to Wembly, near Harrow, gave him even more time for study, and we read of an appliance by which he proposed to facilitate some kinds of sewing. He seems to have pleased his employer well, for in September 1838 he was advanced to a post of draughtsman in connection with the "Gloucester and Birmingham" railway, at a salary of £120 yearly. Thus the next two years were spent at Worcester, where he had his first experience of working alongside of other young men, to whom he appeared rather an "oddity," though not one to be "quizzed." His "mental excursiveness" grew stronger and stronger, and had occasionally useful results, leading, for instance, to an article in The Civil Engineer and Architect's Journal (May 1839) on a new plan of projecting the spiral courses in skew bridges, to a re-invention of Nicholson's Cyclograph, and to an improvement in the apparatus for giving and receiving the mail-bags carried by trains.
Many Inventions.—In 1840, Spencer became engineering secretary to his chief, Captain Moorson, and went to live in the little village of Powick, about three miles out of Worcester. He enjoyed his work, and had the new experience of establishing relations with a number of children, with whom he soon became a favourite. Long afterwards, in his declining years he found much gratification in making friends with children, and referred to it quaintly as "a vicarious phase of the philoprogenitive instinct." It was at Powick that Spencer first began to have a conscience about his very defective spelling (his morals had always been sans reproche) and to take an interest in style. It was at Powick, too, in a physical and social environment that suited him, that Spencer invented his "Velocimeter," a little instrument for showing by inspection the velocity of an engine, and two or three other devices. He had inherited his father's constructive imagination, and his father's discipline had increased it. The father wrote on July 3rd, 1840, "I am glad you find your inventive powers are beginning to develop themselves. Indulge a grateful feeling for it. Recollect, also, the never-ceasing pains taken with you on that point in early life." And the son remarks gratefully that this conveys a lesson to educators; the inherited endowment is much, but the fostering of it is also much. "Culture of the humdrum sort, given by those who ordinarily pass for teachers, would have left the faculty undeveloped." On the whole, however, Spencer attached most importance to the hereditary endowment, for he goes on to say that Edison, "probably the most remarkable inventor who ever lived," was a self-trained man, and that Sir Benjamin Baker, "the designer and constructor of the Forth Bridge, the grandest and most original bridge in the world, received no regular engineering education." It was at Powick, too, that place of many inventions, that Herbert Spencer (aetat. 20) made the intimate acquaintance of an "intelligent, unconventional, amiable, and in various ways attractive" young lady, who "tended to diminish his brusquerie." Luckily or unluckily, the young lady was engaged; and Spencer remarks, "It was pretty clear that had it not been for the pre-engagement our intimacy would have grown into something serious. This would have been a misfortune, for she had little or nothing and my prospects were none of the brightest." Here the ancestral prudence crops out.
Glimpses of Evolution-Idea.—The year 1840-41 was "a nomadic period," of bridge-building at Bromsgroove and Defford, of "castle-building," too, for he dreamt of making a fortune by successful inventions, of testing engines, and other routine duties,—a life involving considerable wear and tear which began to tell on Spencer's eyes. During this period he renewed his youth by collecting fossils, and "making a collection is," as he afterwards said, "the proper commencement of any natural history study; since, in the first place, it conduces to a concrete knowledge which gives definiteness to the general ideas subsequently reached, and, further, it creates an indirect stimulus by giving gratification to that love of acquisition which exists in all." It was then that the purchase of Lyell's Principles of Geology led him, curiously enough, to adopt the supposition that organic forms have arisen, not by special creation, but by progressive modifications, physically caused and inherited. In spite of Lyell's chapter refuting Lamarck's views concerning the origin of species, it was with Lamarck that Spencer, at the age of twenty, sided. The idea of natural genesis was in harmony with the general idea of the order of Nature towards which Spencer had been growing. "My belief in it never afterwards wavered, much as I was, in after years, ridiculed for entertaining it."
"The incident illustrates the general truth that the acceptance of this or that particular belief, is in part a question of the type of mind. There are some minds to which the marvellous and the unaccountable strongly appeal, and which even resent any attempt to bring the genesis of them within comprehension. There are other minds which, partly by nature and partly by culture, have been led to dislike a quiescent acceptance of the unintelligible; and which push their explorations until causation has been carried to its confines. To this last order of minds mine, from the beginning, belonged."
Spencer's engagement with Capt. Moorson came to a natural termination, and an offer of a permanent post on the Birmingham and Gloucester railway was declined, one motive being a desire to prepare for the future by a course of mathematical study, another being to work at an idea his father had arrived at of an electro-magnetic engine. Thus his twenty-first birthday was spent at home in Derby, after an absence of three and a half years,—which had been on the whole "satisfactory, in so far as personal improvement and professional success were concerned."
