Thirteenth Lecture

The deepest riddles of life are contained in what I have now more or less abstractly discussed, and we can approach these riddles by taking together various aspects of what is scattered in our anthroposophical considerations today. The world of ideas appears abstract to us, pictorial to us! Where do we use it first? We use it when we think through what affects our senses from the outside world – colors, sounds, warmth and cold. We think through our perceptions. You will find more precise details in my books 'Truth and Science' and 'Philosophy of Freedom'. When we penetrate our perceptions with thinking, we use this world of ideas to imprint it, as it were, on our spiritual and psychological experience, on what we have as a world of perception. But we need to look a little more closely at what is actually happening. And this can be done by directing one's own soul abilities through spiritual scientific methods, as described in my books. One can actually raise the question: What would it be like if our sensory perceptions only penetrated us from the outside, if only what penetrates our eye as color, our ear as sound, our sense of warmth as heat, and so on, from the light, what would happen to us then?
