Initiation into Philosophy by Émile Faguet. The aim of philosophy is to seek the explanation of all things: the quest is for the first causes of everything, and also how all things are, and finally why, with what design, with a view to what, things are. That is why, taking "principle" in all the senses of the word, it has been called the science of first principles. Philosophy has always existed. Religions-all religions-are philosophies. They are indeed the most complete. But, apart from religions, men have sought the causes and principles of everything and endeavoured to acquire general ideas. These researches apart from religious dogmas in pagan antiquity are the only ones with which we are here to be concerned.
