The Philosophy of Spiritual Activity

There are two fundamental problems in the life of the human mind, to one or other of which everything belongs that is to be discussed in this book. One of these problems concerns the possibility of attaining to such a view of the essential nature of man as will serve as a support for whatever else comes into his life by way of experience or of science, and yet is subject to the suspicion of having no support in itself and of being liable to be driven, by doubt and criticism, into the limbo of uncertainties.
