A man can be so attuned in his soul—for the present it is immaterial by which of these twelve "mental-zodiacal signs" his soul is illuminated—that the soul-mood expressed in the whole configuration of his world-outlook can be designated as Gnosis. A man is a Gnostic when his disposition is such that he gets to know the things of the world not through the senses, but through certain cognitional forces in the soul itself. A man can be a Gnostic and at the same time have a certain inclination to be illuminated by e.g. the mental-zodiacal-sign that we have here called “Spiritism". Then his Gnosticism will have a deeply illuminated insight into the relationships of the spiritual worlds. But a man can also be, e.g. a Gnostic of Idealism; then he will have a special proclivity for seeing clearly the ideals of mankind and the ideas of the world. Thus there can be a difference between two men who are both Idealists. One man will be an idealistic enthusiast who always has the word "ideal", “ideal", “ideal", on his lips, but does not know much about idealism; he lacks the faculty for conjuring up ideals in sharp outline before his inner sight. The other man not only speaks of Idealism, but knows how to picture the ideals clearly in his soul. The latter, who inwardly grasps Idealism quite concretely—as intensely as a man grasps external things with his hand—is a Gnostic in the domain of Idealism. Thus one could say that he is basically a Gnostic, but is specially illuminated by the mental-zodiacal-sign of Idealism.
There are also persons who are specially illuminated by the world-outlook sign of Realism. They go through the world in such a way that their whole mode of perceiving and encountering the world enables them to say much, very much, to others about the world. They are neither Spiritists nor Idealists; they are quite ordinary Realists. They are equipped to have really fine perceptions of the external reality around them, and of the intrinsic qualities of things. They are Gnostics, genuine Gnostics, only they are Gnostics of Realism. There are such Gnostics of Realism, and Spiritists or Idealists are often not Gnostics of Realism at all. We can indeed find that people who call themselves good Theosophists may go through a picture-gallery and understand nothing about it, whereas others who are not Theosophists at all, but are Gnostics of Realism, are able to make an abundance of significant comments on it, because with their whole personality they are in touch with the reality of the things they see. Or again, many Theosophists go out into the country and are unable to grasp with their whole souls anything of the greatness and sublimity of nature; they are not Gnostics of Realism.
There are also Gnostics of Materialism. Certainly they are strange Gnostics. But quite in the sense in which there are Gnostics of Realism, there can be Gnostics of Materialism. They are persons who have feeling and perception only for all that is material; persons who try to get to know what the material is by coming into direct contact with it, like the dog who sniffs at substances and tries to get to know them intimately in that way, and who really is, in regard to material things, an excellent Gnostic. One can be a Gnostic in connection with all twelve world-outlook signs. Hence, if we want to put Gnosis in its right place, we must draw a circle, and the whole circle signifies that the Gnosis can move round through all twelve world-outlook signs. Just as a planet goes through all twelve signs of the Zodiac, so can the Gnosis pass through the twelve world-outlook signs. Certainly, the Gnosis will render the greatest service for the healing of souls when the Gnostic frame of mind is applied to Spiritism. One might say that Gnosis is thoroughly at home in Spiritism. That is its true home. In the other world-outlook-signs it is outside its home. Logically speaking, one is not justified in saying that there could not be a materialistic Gnosis. The pedants of concepts and ideas can settle such knotty points more easily than the sound logicians, who have a somewhat more complicated task. One might say, for example: “I will call nothing ‘Gnosis’ except what penetrates into the ‘spirit’.‿ That is an arbitrary attitude with regard to concepts; as arbitrary as if one were to say, “So far I have seen violets only in Austria; therefore I call violets only flowers that grow in Austria and have a violet color—nothing else.‿ Logically it is just as impossible to say that there is Gnosis only in the world-outlook-sign of Spiritism; for Gnosis is a “planet" which passes through all the mental-constellations.
