the scheme of human education formerly taken by 
languages and philosophy. I shall not—it would be 
presumptuous on my part to attempt to do so—say 
anything to disparage the claims of science. It is 
essential, not only to industry and commerce and 
progress of every material kind, but also indispensable 
as part of education itself, opening up to us the whole 
dealings of nature and God’s dealings with men 
through nature, which it is essential that an educated 
man should possess. But any scheme of education 
is narrow and imperfect which does not reserve an 
important place for the human subject. A knowledge 
of men, their nature and literature, their history, their 
institutions, social and political, and their economic 
life—a knowledge of men and everything about men 
is at least as vital and essential to us as a knowledge 
of nature.” :
