What we must do now is something that has never been done seriously on either side and has never been done radically and consistently: we must go from the scientific fundamental concepts back to the contents of pure experience, we must radically set aside all presumptions of exact science, all its peculiar conceptual superstructures in other words, we must consider the world as if these sciences did not yet exist, the world precisely as life world, just as it maintains its coherent existence in life throughout all its relativity, as it is constantly outlined in life in terms of validity.
