From the beginning there has been something irreplaceable in philosophy. Through all the change in human circumstances and the tasks of practical life, through all the progress of the sciences, all the development of the categories and methods of thought, it is forever concerned with apprehending the one eternal truth under new conditions, with new methods and perhaps with greater possibilities of clarity. It is our task today, amid the most extreme nihilism, to ascertain this truth once more.

— Karl Jaspers
