Pietism Quotes
The philosophical thought of Kant, the supreme flower of the Germanic people, has its roots in the religious feeling of Luther, and it is not possible for Kantism, especially the practical part of it, to take root and bring forth flower and fruit in peoples who have not undergone the experience of the Reformation and who perhaps were incapable of experiencing it. Kantism is Protestant, and we Spaniards are fundamentally Catholic. And if Krause struck some roots here - more numerous and more permanent than is commonly supposed - it is because Krause has roots in pietism, and pietism, as Ritschl has demonstrated in his Geschichte des Pietismus, has specifically Catholic roots and may be described as the irruption, or rather the persistence of Catholic mysticism in the heart of Protestant rationalism. And this explains why not a few Catholic thinkers in Spain became followers of Krause.
