which some of the proposed remedies for social troubles were based, and
this examination may be found in his "Collected Essays." But the
educational campaign which he carried on in England had its counterpart
in America. It was not only that he was chosen to open the Johns Hopkins
University as the type of a new form of education; there and elsewhere
pupils of his carried out in America his methods of teaching biology,
while others engaged in general education would write testifying to the
influence of his ideas upon their own methods of teaching. But it must
be remembered that nothing was further from his mind than the desire to
found a school of thought. He only endeavoured as a scholar and a
student to clear up his own thoughts and help others to clear theirs,
whether in the intellectual or the moral world. This was the help he
steadfastly hoped to give the people, that interacting union of
intellectual freedom and moral discernment which may be furthered by
good education and training, by precept and example, that basis of all
social health and prosperity. And if, as he said, he would like to be
remembered as one who had done his best to help the people, he meant
assuredly not the people only of his native land, but the wider world to
whom his words could be carried.
