continue to control our actions.

Since we are loaded with the popular ideas which we have absorbed
from our environment, it will be well for us to begin by
critically examining our environment and the process by which
ideas have been taken in. This may enable us to put out some of
the erroneous views, and perhaps more firmly fix the true ideas;
thereby preparing the mind for a more ready acceptance of what
otherwise would be barred out as contradictory.

We shall not go deeply into the psychology of the subject, as it
will not be necessary to go contrary to or beyond the well-known
facts.

We shall not try to locate the man or refer to him as the ego or
inner man. We shall simply say that we know that we can use our
brains to think on any subject, and we can use our senses to
collect information regarding any chosen subject.

Our senses and mental faculties can be directed to consider one
element in a business, and for the moment be unmindful of the many
other elements. In other words, we can to a certain extent manage
our mental processes. Just as a horse can be managed, so may we
manage our brains. A driver may carefully control the expenditure
of energy and the course traveled, or he may throw the reins over
the dash and allow the horse to go his own gait and route. In the
same way we may manage or mismanage our brains.
