2. Those who are unfamiliar with Spiritism believe that spirit phenomena can be produced in the same way that other phenomena can be produced in physics and chemistry experiments. Hence, their intention to subject them to their will and their refusal to place themselves in the conditions needed to observe them. Since in principle they do not believe in the existence and intervention of spirits - at least they do not understand their nature or their modes of action - they act as if they were dealing with raw matter and since they do not get what they were asking for, they conclude ' that there are no spirits after all.
If they would look at the issue from a different perspective, they would understand that spirits are human souls, that after death we ourselves will be spirits and that we too would be ill-disposed to serve as playthings to satisfy the fantasies of the curious.
