42. By the same means the spirit acts upon the table, either to make it simply to move, or give intelligent raps, indicating the letters of the alphabet, in order to form words or phrases, a phenomenon named “typtology.” Here the table is only an instrument for use, as a pencil in writing. It gives to it a momentary vitality by the fluid with which it penetrates it; but it does not identify itself with it. Persons who, in their emotion at being able to communicate with spirits dear to them, embrace the table perform a foolish act; for it is absolutely the same as if they should embrace the stick which a friend uses to make the raps. It is equivalent to saying that the spirit was enclosed in the wood of the table, or that the wood had become a spirit.
When communications like these take place, it is necessary to represent the spirit as not in the table, but beside us as he was in life; and thus they would see him if their spiritual eyes were open. The same takes place when one obtains communications by writing; one would see the spirit beside the medium, directing or transmitting to him his ideas by a fluidic-current.
