23O THE LAW OF PSYCHIC PHENOMENA.
trary, in the fact that there is room for a doubt on that question. It is self-evident that if facts, known neither to the medium nor those surrounding him, that is, facts not known to him nor obtainable by means of telepathy, can be perceived or obtained by him from independent sources, the evidence of that fact would be thrust upon us from ten thousand different sources every hour. This is also negative evidence, it is true, but it is all but conclusive. Thus, the question of spirit identity has given spiritists no end of trouble. Their ablest writers have sought in vain for a solution of the question why it is that spirits constantly fail to give conclusive evidence of their identity by means which could not be referred to the knowledge of the medium or to telepathy.
On this subject Allan Kardec, one of the ablest writers on the subject, discourses as follows:
" The identity of contemporaneous spirits is much more easily proved, those whose character and habits are known ; for it is precisely these habits, which they have not yet had time to throw aside, by which they can be recognized." 1
This may be true; but it is also true that where the " character and habits " of a supposed spirit are known to the medium, or to those who are in telepathic rapport with him, simulation of that character and those habits is perfectly easy to the expert medium. The more generally the character and habits are known, the less evidential value is to be attached to their reproduction.
Our author then proceeds :

In leaving his body the spirit has not laid aside his susceptibility; he is wounded by any question tending to put him to the proof.
