Lecture XI

Logic may indeed be applied to all worlds, but can only be applied directly to the physical world; hence when it appears as human logic it is bound unconditionally to its instrument, the physical brain. Abstract thought could never have entered the world without a further descent into the world of the senses. This development of logical thought is bound up with the loss of ancient clairvoyant vision, and was bought at the cost of this loss. The task of man is to re-conquer clairvoyant vision, adding logical thought to it. In time to come he will obtain imagination as well, but logical thinking will be retained.
