m which shows why a
third proposition must necessarily result if two others are assumed, but
which does not help us to determine whether the two initial statements are
true or not. To determine this is the province of inductive reasoning which
draws its conclusions from the observation of a series of facts. The
relation of the two modes of reasoning is that, first by observing a
sufficient number of instances, we inductively reach the conclusion that a
certain principle is of general application, and then we enter upon the
deductive process by assuming the truth of this principle and determining
what result must follow in a particular case on the hypothesis of its
truth. Thus deductive reasoning proceeds on the assumption of the
correctness of certain hypotheses or suppositions with which it sets out:
it is not concerned with the truth or falsity of those suppositions, but
only with the question as to what results must necessarily follow supposing
them to be true. Inductive reasoning; on the other hand, is the process by
which we compare a number of separate instances with one another until we
see the common factor that gives rise to them all. Induction proceeds by
the comparison of facts, and deduction by the application of universal
principles. Now it is the deductive method only which is followed by the
subjective mind. Innumerable experiments on persons in the hypnotic state
have shown that the subjective mind is utterly incapable of making the
selection and comparison which are necessary to the inductive process, but
will accept any suggestion, however false, but having once accepted any
suggestion, it is strictly logical in deducing the proper conclusions from
it, and works out every suggestion to the minutest fraction of the results
which flow from it.

As a consequence of this it follows that the subjective mind is entirely
under the control of the objective mind. With the utmost fidelity it
reproduces and works out to its final consequences whatever the objective
mind impresses upon it; and the facts of hypnotism show that ideas can be
impressed on the subjective mind by the objective mind of another as well
as by that of its own individuality. This is a most important point, for it
is on this amenability to suggestion by the thought of another that all the
phenomena of healing, whether present or absent, of telepathy and the like,
depend. Under the control of the practised hypnotist the very personality
of the
