The portrait of Herbert Spencer, which forms the frontispiece to this number of the Monthly, is from a photograph taken soon after he reached the age of seventy-eight. Though of late years his health has been unusually feeble, this is scarcely reflected in the face, which still retains in a marked degree the expression of intellectual strength that was so characteristic of his prime.

About the time Mr. Spencer completed the Synthetic Philosophy, or, as it is better known, the Philosophy of Evolution, with the publication of the third volume of the Principles of Sociology, we gave an account of The Man and his Work, from the pen of Prof. William H. Hudson, who had for a number of years acted as his secretary, and was so familiar with his thought that he afterward published an Introduction to the Philosophy, which Mr. Spencer himself has cordially commended. It was naturally supposed by his many friends that having practically carried out his original plan as laid down in his prospectus thirty-six years before, Mr. Spencer would throw off the cares and vexations of authorship, to enjoy the rest and relaxation that his arduous and long-continued labors had earned. But this, it seems, he was not inclined to do. Apparently as active intellectually as ever, he has kept at work to the full extent of his physical ability, devoting himself mainly to such additions and modifications of his published writings as new knowledge and the advance of thought have made necessary. This persistent industry, unusual, to say the least, in one so far advanced in life, the presentation of his latest portrait, and the interest which the world takes in the doings of a man who has so profoundly influenced the thought of his time, make this a fitting opportunity to refer to some of the later incidents in his career.

Though never inclined to plume himself on the importance or the grandeur of his great undertaking, wondering now that he ever had the "audacity" to begin it, and regarding its completion as more an "emancipation" than a triumph, Mr. Spencer is nevertheless entitled to the satisfaction which comes from the contemplation in the evening of a long life of the fulfillment of the purpose to which that life has been devoted. Although he speaks of the series of works comprising the Synthetic Philosophy as "complete yet incomplete," because more things might have been put into it, Mr. Spencer has the unquestionable right to look upon his "system" as finished in all the essentials of a symmetrical and self-sustaining structure; and more than this, he finds it generally accepted as a masterpiece, embodying, if not all the truth, yet a fundamental truth manifested in the growth and order of the universe of matter and mind.

When we regard the comprehensiveness of Mr. Spencer's system, embracing everything there is, and the multitude of the details that had to be considered in the course of its preparation, we wonder at the magnitude of the aggregation that may be formed by the repetition of small daily tasks. The portions of time he was able to give to work were at most very brief, and would be regarded by the majority of workers as insufficient for any great accomplishment; and when the frequent and sometimes long interruptions that occurred are considered, seem absolutely insignificant. Yet in these small fragments of two or three hours a day with many lost days in the year, and several lost years, one of the greatest works in the history of the human mind was carried to its end. The old figure of the dropping of the water on the stone and the fable of the tortoise and the hare are newly illustrated.

Outside of his work in the composition of the Philosophy, Mr. Spencer has always taken a vital interest in leading public questions, making them the subjects of frequent communications to the press, and seeking the co-operation of others when opportunity offered either in combating some needless innovation or aiding some important reform. True to the teaching of his philosophy, it will be observed that in any attempts of the kind his reliance has always been on the power of gradual development, rather than abrupt changes by acts of Parliament or otherwise, to bring about desired conditions. Before his visit to the United States, in 1882, he interested himself in forming an Anti-Aggression League, for the purpose of opposing schemes for extending the lines of British dominion in various parts of the world. Among his associates in this effort were Mr. John Morley, Mr. Frederic Harrison, and the Rev. Llewellyn Davis and Canon Fremantle, now Dean of Ripon, liberal-minded clergymen of the Church of England. The movement found little public sympathy, and no adequate support. Mr. Spencer, severely taxing his strength in promoting it, suffered another breakdown (from which he has never fully recovered), in consequence of which the next number of his Philosophy—Part VI of the Principles of Sociology: Ecclesiastical Institutions—did not appear till the close of 1855. It is worthy of remark in connection with this incident that it seems to have been left for non-Christians almost alone in a professedly Christian community to take the advance in inculcating and disseminating one of the central ideas of the Christian religion; as now, in the United States, with the orthodox church people almost unanimous in supporting war and the wildest schemes of aggression, it has been left for a few New England Unitarians first to dare to speak in protest against an iniquitous and perilous crusade for foreign dominion. Mr. Spencer has never neglected an opportunity to express in unmistakable terms his aversion to militancy, and has been at great pains to demonstrate, as in his Sociology, that the true road to all higher development of society is through encouraging the growth of its industrial factors.

A disposition manifested among English legislators to favor the passage of acts embodying some of the ideas of the socialists led to the publication of a series of magazine articles showing the demoralizing tendencies of measures of paternalism and foreshadowing the disastrous ultimate results that would ensue from the unnecessary interference of the state. These were afterward collected and published under the title of The Man versus the State, and are now bound up with the revised Social Statics.

From the spring of 1886 till 1889, when conditions of health compelled entire suspension of the work on the Philosophy, and it was even doubtful whether it could ever be continued, Mr. Spencer dictated the larger part of his autobiography. This has since been completed and put in print, but will not be published during his lifetime. It will comprise two considerable volumes.

Not finding life in a boarding house in all respects suited to his wishes, Mr. Spencer for many years entertained the idea of establishing himself in a home of his own in the suburbs of London, but had been deterred from so doing by the prospective troubles of housekeeping. In the summer of 1889, however, after making such arrangements as promised to relieve him in great measure of these cares, he finally carried out the idea by taking a house in the neighborhood of Regent's Park. But though for some years the bachelor household was a success, we understand it eventually ceased to be so, though it was continued until Mr. Spencer changed his residence to Brighton two years ago. There was wanting in those who had immediate charge of details that feeling of identity of interests and that disposition to co-operate which belong to the ordinary family, and as a consequence differences grew up that could not be permanently composed, and that on the whole did not conduce to domestic tranquillity.

About the time his housekeeping experience was entered upon, Mr. Spencer found himself well enough to go on with the composition of his Philosophy. As he relates in the preface to the Data of Ethics and to Justice, he had already, ten years before, in the imminent doubt of ever being able to complete the work as it had been laid out, determined to devote his attention first to the end and ultimate object of the system—to that part of it to which all the rest was intended to lead up; the purpose, "lying behind all proximate purposes," of finding a scientific basis for the principles of right and wrong in conduct at large. When, now, the question arose again of what work to undertake first, completion of the Principles of Ethics was at once decided upon. As it was still doubtful whether he would be able to accomplish even this, he took up the part which seemed most important—Justice. This was published as Part IV of the Ethics in the summer of 1891. No further serious interruptions occurred in the execution of the work. Parts II and III, completing the first volume of the Ethics, were finished in the spring of 1892; and a year afterward Parts V and VI were added, forming, with Justice, the second volume.

The ethical part of the Philosophy as contemplated by Mr. Spencer having been completed, only two divisions remained to be worked out—Professional Institutions and Industrial Institutions, parts of the Principles of Sociology—to fill out the whole plan. A subsidiary discussion of considerable importance for the integrity of the theory of evolution now intervened to be disposed of before these parts of the work could be proceeded with. Prof. August Weismann had published a book in which he denied the transmission of acquired characters; or, as Mr. Spencer would word it, the transmission of functionally-wrought modifications—a very vital point in all Mr. Spencer's philosophy. Mr. Spencer took the matter up at once, and published several incisive essays refuting Professor Weismann's positions. He opened his argument against the neo-Darwinian position with essays on the Inadequacy of Natural Selection, and on Professor Weismann's Theories, and followed them, at intervals of a few months, with the additional articles, A Rejoinder to Professor Weismann, and Weismannism Once More. Anxious that the question should be brought to the notice of every biologist, Mr. Spencer had reprints of these essays distributed among the teachers of the science all over Europe and America.
