ProofWeb is an interactive way of exploring hundreds of arguments from the history of philosophy. It knows the logical relations? between propositions?, and so can show you what those you accept imply - or what might imply those you have yet to accept.
Below you can explore these arguments from two angles, either seeing famous arguments for conclusions like the existence of God or checking whether there is a proof from propositions you already accept to conclusions you don't, such as the counter-intuitive 'sceptical' position that you cannot know anything about the external world.
