The Federation of Mankind
To take but one instance. How confident were the assertions made in the days preceding the unification of the states of the North American continent regarding the insuperable barriers that stood in the way of their ultimate federation! Was it not widely and emphatically declared that the conflicting interests, the mutual distrust, the differences of government and habit that divided the states were such as no force, whether spiritual or temporal, could ever hope to harmonize or control? And yet how different were the conditions prevailing a hundred and fifty years ago from those that characterize present-day society! It would indeed be no exaggeration to say that the absence of those facilities which modern scientific progress has placed at the service of humanity in our time made of the problem of welding the American states into a single federation, similar though they were in certain traditions, a task infinitely more complex than that which confronts a divided humanity in its efforts to achieve the unification of all mankind.
