 Concurrently, Friedrich Nietzsche built on ideas from Kant which emphasized the experience of space as a force field generated by human movement and perception.Martin Heidegger would later contradict both of these schools.In his 1927 "Being and Time" and 1951 "Building, Dwelling, Thinking" he claimed that space was neither a construct of the mind nor a given, but was "that for which a room has been made" and was created by the object within a room rather than the room itself.
