When we cast a glance upon the immense progress realized by the natural sciences in the course of the nineteenth century, and when we perceive the promises they contain for the future, we can not but feel deeply impressed by the idea that mankind is entering upon a new era of progress It has, at any rate, before it all the elements for preparing such a new era.

Such attempts at a constructive synthetic philosophy were made several times during the nineteenth...
