Mention the 18th century Royal Navy and visions come to mind of swashbuckling sailors swinging from rope to rope while a red-faced captain in an even redder coat and a powdered wig shouts order and pitches fits. Such visions naturally fail to do full justice to a group of men who functioned, with little direction and even less support, on the seas for years at a time. Disney may enjoy portraying them sitting down to sumptuous feasts or cavorting with scantily clad native girls, but the opposite was true.

The Critique of Pure Reason, published in 1781, by German philosopher Immanuel Kant, cornerstone of modern philosophy, is one of the most important works on metaphysics ever published and is often seen as the culmination of centuries of early-modern philosophical thought. The Critique of Pure Reason, also known as The First Critique, incorporates in-depth discussions on empirical reason, "pure" reason, human knowledge as a whole, space and time, cause and effect, and much, much more.
