Before I begin, I'd like to personally thank whatever may remain of Immanuel Kant for saving my bacon during my A-Level Philosophy exam. Without a vague, semi coherent allusion to his work which I lovingly peppered with 'categorical imperative' and 'ethical maxim' every so often like a master chef, I doubt that I'd have managed a half-decent grade. Thanks Kant. Hegel, I owe you nothing.
Both Kant and Hegel are German idealist philosophers, meaning their philosophy is based around the idea that human experience of the world is only a rough approximation of what actually exists.
