"The philosophy of a purely theoretical thinker, who contemplates all things from the point of view of things in themselves, belongs in the same class as the attempt to apply abstract thought to the entire field of consciousness without meeting any byways or stops. Look at Baruch Spinoza, that true hero of thought, who studied in his own person the way in which the emotions and passions, as expressions of his internal mechanism, transform themselves for him into objects of geometrical analysis! In the meantime, until the heroism of Baruch Spinoza shall become the matter-of-fact virtue of everyday life in the higher developed humanity of the future, and until myths, poetry, metaphysics and religion shall no longer overshadow the field of consciousness, let us be content that up to now, and for the present, philosophy in its differentiated and its improved sense has served, and serves, as a critical instrument and helps science to keep its formal methods and logical processes clear; that it helps us in our lives to reduce the obstacles, which the fantastic projections of the emotions, passions, fears and hopes pile in the way of free thought; that it helps and serves, as Spinoza himself would say, to vanquish imaginationem et ignorantiam."
