The German language site Philolex, designed and maintained by Peter Möller, is dedicated to the subject of philosophy. The site provides an alphabetical list of philosophers, and there is also a section designated to philosophical concepts. As well as dealing with German philosophers such as Friedrich Nietzsche, Immanuel Kant and Nicolai Hartmann, there are also entries for many other European thinkers such as Voltaire, Socrates and Francis Bacon. The site provides a detailed list of works written by each philosopher and many texts are available online via the Gutenberg Project. There are summaries of the main philosophical concepts of each philosopher, as well as discussions and critiques, and links are provided to other useful sites. Unfortunately some of the pages are rather long, involving a considerable amount of scrolling.
