“We have now reached that stage that we must admit that there is a mind within us, in our inner world, and a mind without us, in the outer world. What we call this mind, the Ego, the soul within us, and the Non-ego, the world-soul, the God without us, is a matter of indifference. The Brahmans appear to me to have found the best expression. They call the fundamental cause of the soul, of the Ego, the Self, and the fundamental cause of the Non-ego, of the World-soul, of God, the highest Self. They go still farther, and hold these two selves to be in their deepest nature one and the same—but of this another time. To-day I am content, if you will admit, that our mind is not mere steam, nor the world merely a steam-engine, but that in order that the machine shall run, that the eye shall see, the ear hear, the mind think, add, and subtract, we need a seer, a hearer, a thinker. More than this I will not inflict on you to-day; but you see that without deviating a finger’s breadth from the straight path of reason, that is from correct and honest addition and subtraction, we finally come to the soul-phantom and to the idea of God, which you look upon with such blood-thirstiness. I have indicated to you, with only a few strokes, the historical course of human knowledge. There still remains much to fill in, which must be gained from history and the diligent study of the sacred books of mankind, and the works of the leading philosophers of the East and the West. We shall then learn that the history of mankind is the best philosophy, and that not only in Christianity and Judaism, but that in all religions of the world, God has at divers times spoken through the prophets in divers manners, and still speaks.
