Importance of this Fact to the Teacher. — This fact of
the interdependence of knowing, feeling, and willing is, as
we know, of cardinal importance to the teacher. Teachers
are coming to feel the importance of knowing the contents
of their pupils' minds, in order that they may adapt their
teaching to them. To go from the known to the unknown
is to make what the pupil knows a starting-point from
which to lead him to something he does not know. Plainly
any attempt to explain the unknown will be a failure un-
less the explanation is made in terms known to the pupil.
For this reason intelligent teachers are always trying to
make a map of their pupils' minds, that they may learn

what points they can help their pupils to start from in
making excursions into the unknown.
But there is another fact just as important which we are
more likely to overlook. When you have arranged an ex-
cursion, there is something else you must do before you
can be sure it will be a success ; you must see to it that
people have a sufficient motive to go on it. So also, when
you have planned a mental excursion for your pupils,
when you have found a place from which they can start,
before you can be sure of their company, you must be sure
that they have a sufficient motive for going with you.
