1. The existence of the spiritual principle is a fact needing no more demonstration than does the existence of the material principle. It is sort of axiomatic truth; it affirms itself by its effects as matter by those which are peculiar to it.
According to the maxim, “all effects have a cause; all intellectual effects must have an intelligent cause.” There is no one who would not see a difference between the mechanical effect of a bell agitated by the wind and the movement of this same bell destined to give a signal, a notice, attesting by that a thought, an intention. Now, as it can occur to no one to attribute the thought to a bell, one concludes that it is moved by an intelligence to which it serves as an instrument of manifestation.
For the same reason no one thinks of attributing thought to the body of a deceased man. If a living man thinks, it is because there exists something in him that is not destroyed by his death. The difference between him and the simple bell is that the intelligence that makes the bell ring is outside of it, whereas that which makes a man act comes from within.
