A chief distinction of the present day is a community of opinions and knowledge amongst men in different nations, existing in a degree heretofore unknown. Knowledge has, in our time, triumphed, and is triumphing, over distance, over difference of languages, over diversity of habits, over prejudice, and over bigotry. The civilized and Christian world is fast learning the great lesson, that difference of nation does not imply necessary hostility, and that all contact need not be war. The whole world is becoming a common field for intellect to act in. Energy of mind, genius, power, wheresoever it exists, may speak out in any tongue, and the _world_ will hear it. A great cord of sentiment and feeling runs through two continents, and vibrates over both. Every breeze wafts intelligence from country to country; every wave rolls it; all give it forth, and all in turn receive it. There is a vast commerce of ideas; there are marts and exchanges for intellectual discoveries, and a wonderful fellowship of those individual intelligences which make up the mind and opinion of the age. Mind is the great lever of all things; human thought is the process by which human ends are ultimately answered; and the diffusion of knowledge, so astonishing in the last half-century, has rendered innumerable minds, variously gifted by nature, competent to be competitors or fellow-workers on the theatre of intellectual operation. From these causes important improvements have taken place in the personal condition of individuals. Generally speaking, mankind are not only better fed and better clothed, but they are able also to enjoy more leisure; they possess more refinement and more self-respect. A superior tone of education, manners, and habits prevails. This remark, most true in its application to our own country, is also partly true when applied elsewhere. It is proved by the vastly augmented consumption of those articles of manufacture and of commerce which contribute to the comforts and the decencies of life; an augmentation which has far outrun the progress of population. And while the unexampled and almost incredible use of machinery would seem to supply the place of labor, labor still finds its occupation and its reward; so wisely has Providence adjusted men's wants and desires to their condition and their capacity.
