The _Encyclopædia Britannica_, Ninth Edition, vol. viii. 1878 274 to 309 XII. THE COMING OF AGE OF “THE ORIGIN OF SPECIES.” An evening Lecture at the Royal Institution, Friday, 9th April 1880.—_Nature_, 1880 310 to 324 XIII. THE CONNECTION OF THE BIOLOGICAL SCIENCES WITH MEDICINE. An Address delivered at the Meeting of the International Medical Congress in London, 9th August 1881 325 to 349 I. SCIENCE AND CULTURE. Six years ago, as some of my present hearers may remember, I had the privilege of addressing a large assemblage of the inhabitants of this city, who had gathered together to do honour to the memory of their famous townsman, Joseph Priestley;[1] and, if any satisfaction attaches to posthumous glory, we may hope that the manes of the burnt-out philosopher were then finally appeased. No man, however, who is endowed with a fair share of common sense, and not more than a fair share of vanity, will identify either contemporary or posthumous fame with the highest good; and Priestley’s life leaves no doubt that he, at any rate, set a much higher value upon the advancement of knowledge, and the promotion of that freedom of thought which is at once the cause and the consequence of intellectual progress. Hence I am disposed to think that, if Priestley could be amongst us to-day, the occasion of our meeting would afford him even greater pleasure than the proceedings which celebrated the centenary of his chief discovery. The kindly heart would be moved, the high sense of social duty would be satisfied, by the spectacle of well-earned wealth, neither squandered in tawdry luxury and vainglorious show, nor scattered with the careless charity which blesses neither him that gives nor him that takes, but expended in the execution of a well-considered plan for the aid of present and future generations of those who are willing to help themselves. We shall all be of one mind thus far. But it is needful to share Priestley’s keen interest in physical science; and to have learned, as he had learned, the value of scientific training in fields of inquiry apparently far remote from physical science; in order to appreciate, as he would have appreciated, the value of the noble gift which Sir Josiah Mason has bestowed upon the inhabitants of the Midland district. For us children of the nineteenth century, however, the establishment of a college under the conditions of Sir Josiah Mason’s Trust, has a significance apart from any which it could have possessed a hundred years ago. It appears to be an indication that we are reaching the crisis of the battle, or rather of the long series of battles, which have been fought over education in a campaign which began long before Priestley’s time, and will probably not be finished just yet.
