Of mediumship there are many grades, one of the simplest forms being the capacity to receive an impression or automatic writing, under peaceful conditions, in an ordinary state; but the whole subject is too large to be treated here.

We know that communication must be hampered, and its form largely determined, by the unconscious but inevitable influence of a transmitting mechanism, whether that be of a merely mechanical or of a physiological character.

The amount of sophistication varies according to the quality of the medium, and to the state of the same medium at different times; it must be attributed in the best cases physiologically to the medium, intellectually to the control.

Oliver Joseph Lodge Quotes
