In an essay on "The Problem of Philosophy at the Present Time," Professor Edward Caird says that "philosophy is not a first venture into a new field of thought, but the rethinking of a secular and religious consciousness which has been developed, in the main, independently of philosophy."[vii:A] If there be any inspiration and originality in this book, they are due to my great desire that philosophy should appear in its vital relations to more familiar experiences. If philosophy is, as is commonly assumed, appropriate to a phase in the development of every individual, it should grow out of interests to which he is already.
