Others ... are in the habit of teaching that religion and philosophy are really the same thing. Such a statement, however, appears to be true only in the sense in which Francis I is supposed to have said in a very conciliatory tone with reference to Charles V: ‘what my brother Charles wants is also what I want', namely Milan. Others again do not stand on such ceremony, but talk bluntly of a Christian philosophy, which is much the same as if we were to speak of a Christian arithmetic, and this would be stretching a point. Moreover, epithets taken from such dogmas are obviously unbecoming of philosophy, for it is devoted to the attempt of the faculty of reason to solve by its own means and independently of all authority the problem of existence.
