All mere dreaming and imagining about the supersensible brings only confusion for they are incapable of satisfying the opponents. The latter are right when they say that such general references to supersensible beings are not an aid to the understanding of the facts. These opponents, it is true, may say the same thing about the definite indications of spiritual science. In this case, however, it can be shown how the effects of hidden spiritual causes appear in outer life.
The following can be maintained: Suppose that what spiritual research has established by means of observation is true, namely, that man after death has passed through a period of purification and that he has experienced psychically during that time how a definite act, which has been performed in a previous life, is a hindrance to further evolution. While he was experiencing this, the impulse developed in him to rectify the consequences of this act. He brings this impulse with him into a new life, and it then forms the trait of character that places him in a position where this rectification is possible. Consider the totality of such impulses, and you have a reason for the destined environment in which a person is born.

The same may apply to another supposition. Again assume that what spiritual science says is true, namely, that the fruits of a past life are incorporated in the spiritual human seed, and that the land of the spirits in which this seed exists between death and rebirth is the realm in which these fruits ripen in order to appear again in a new life changed into talents and capacities, and to form the personality in such a way that it appears as the effect of what has been gained in a former life. —
Anyone who makes these assumptions and, with them, observes life without prejudice will see that through them all facts of the sense world can be acknowledged in their full significance and truth, while at the same time everything becomes comprehensible that must remain forever incomprehensible to the one who, while relying only on physical facts, directs his attitude of mind toward the spiritual world. Above all, every illogical assumption will disappear, for instance the one mentioned above, that because the most important name stands at the end of a blood relationship series, the bearer of that name must have inherited his talents. Life becomes logically comprehensible by means of the supersensible facts communicated by spiritual science.
