Note VIII.
If numerous immigrants were to enter a foreign country, there would be among them every class of people, all capacities, all characters, all degrees of learning and morality. If we asked them for information about the laws and customs of their country, they would give it to us with greater or lesser accuracy, according to their knowledge and the social position of each one. We would surely form a quite false idea of the physical and moral state of the country if we relied on the first one who came along, merely because he came from such a country. The same thing happens in the spiritual world; the Spirits speak to us only of what they know, and it is by the language they use that we can judge their aptitude to describe it to us.
