4. Anthroposophical Spiritual Science and the Great Questions of Civilization in the Present Day

But one must do such exercises for years. And what one has to accomplish within the soul is truly no easier than what one accomplishes in the laboratory, in the physics room, or at the observatory. Outward research is no more difficult to acquire than that which is carefully and conscientiously cultivated in the soul over many years. But then certain inner soul powers, which we otherwise only know as powers of remembrance, become stronger, and thus something arises in us as soul power that we have not known at all before. This enables us to clearly recognize what materialism says about the power of memory and remembrance. Materialism tells us that the human being's power of remembrance is bound to the material body; if something in the nervous system is not properly constituted, then the power of remembrance also declines, and it declines with age. In any case, mental powers depend on physical development. Spiritual science does not deny this for the life between birth and death. For someone who is developing his memory as I have just described it knows from direct experience how the ordinary memory, which conjures up images of our experiences before our soul, is dependent on the human body. But what he is now developing becomes completely independent of the human body.
