What leads people today to regard the science of spirit as nonsensical and irrelevant? It is because they are unconsciously afraid of the powers that have to be developed in order to grasp the spirit in a completely free kind of experience of the spirit. For courage is necessary for such investigation, courage to believe that we do not immediately fall into an abyss of nothingness when we are dependent upon our own powers for producing a particular kind of experience which we ourselves place before our souls. It is certainly easier to want to penetrate the mysteries of life with outer means than to be told that the soul needs an inner strengthening far beyond anything found in ordinary life. It is therefore largely a matter of comfort and fear that leads to opposition to the science of spirit. Such things, however, will gradually be overcome by a humanity that is increasingly thirsting for truth.
