The broad and vague concept "life' is used in the present context in the narrower sense of habits, modes of behavior, acts and activities. We employ the concept "life' when we speak of man's life as the sum-total of the deeds he has performed and the experiences he has undergone. It is in this sense that we inquire into the attitude of philosophy to life and its influence upon it. We shall begin our discussion with an examination of the two extreme views found in philosophical speculation with regard to this subject. Since philosophy is deliberate knowledge, it is clear that philosophy itself raises the question of its relation to the different spheres, including the sphere of life.
