Again, there are people who, owing to a certain inwardness, are naturally predisposed to see in all that is material only the revelation of the spiritual. Naturally, they know as well as the materialists do that, externally, the material world exists; but matter, they say, is only the revelation, the manifestation, of the underlying spiritual. Such persons may take no particular interest in the material world and its laws. As all their ideas of the spiritual come to them through their own inner activity, they may go through the world with the consciousness that the true, the lofty, in which one ought to interest oneself – all genuine reality—is found only in the Spirit; that matter is only illusion, only external phantasmagoria. This would be an extreme standpoint, but it can occur, and can lead to a complete denial of material life. We should have to say of such persons that they certainly do recognize what is most real, the Spirit, but they are one-sided; they deny the significance of the material world and its laws. Much acute thinking can be enlisted in support of the conception of the universe held by these persons. Let us call their conception of the universe: Spiritism. Can we say that the Spiritists are right? As regards the Spirit, their contentions could bring to light some exceptionally correct ideas, but concerning matter and its laws they might reveal very little of any significance. Can one say the Materialists are correct in what they maintain? Yes, concerning matter and its laws they may be able to discover some exceptionally useful and valuable facts; but in speaking of the Spirit they may utter nothing but foolishness. Hence we must say that both parties are correct in their respective spheres.
