"Windelband, the historian of philosophy, in his essay on the meaning of philosophy (Was ist Philosophie? in the first volume of his Präludien) tells us that "the history of the word 'philosophy' is the history of the cultural significance of science." He continues: "When scientific thought attains an independent existence as a desire for knowledge, it takes the name of philosophy; when subsequently knowledge as a whole divides into its various branches, philosophy is the general knowledge of the world that embraces all other knowledge. As soon as scientific thought stoops again to becoming a means to ethics or religious contemplation, philosophy is transformed into an art of life or into a formulation of religious beliefs. And when afterwards the scientific life regains its liberty, philosophy acquires once again its character as an independent knowledge of the world, and in so far as it abandons the attempt to solve this problem, it is changed into a theory of knowledge itself." Here you have a brief recapitulation of the history of philosophy from Thales to Kant, including the medieval scholasticism upon which it endeavored to establish religious beliefs. But has philosophy no other office to perform, and may not its office be to reflect upon the tragic sense of life itself, such as we have been studying it, to formulate this conflict between reason and faith, between science and religion, and deliberately to perpetuate this conflict?"
