In this book, generally held to be the key to his view of an academic approach to phenomenology, Edmund Husserl (1859-1938) sets out his ideas on the subject of 'pure' phenomenology, taking account of the idealist agnosticism he was inspired by throughout his life and which prevented him from ever crossing the threshold to the object world, a threshold considered 'out of bounds' by Kant and all other German philosophers. According to the German idealist view still upheld today, there can be only limited knowledge about the nature of the world and the internal impressions it leaves on us.
