it for himself to all the others.

Take such a sentence as this: African explorers are subject to fevers
which cause restlessness and delirium.

Note the expression, "cause restlessness." _Restlessness has a cause._
Clearly, then, any one who wished to get rid of restlessness would
proceed at once to deal with the cause. If that were not removed, a
doctor might prescribe a hundred things, and all might be taken in
turn, without producing the least effect. Things are so arranged in
the original planning of the world that certain effects must follow
certain causes, and certain causes must be abolished before certain
effects can be removed. Certain parts of Africa are inseparably linked
with the physical experience called fever; this fever is in turn
infallibly linked with a mental experience called restlessness and
delirium. To abolish the mental experience the radical method would be
to abolish the physical experience, and the way of abolishing the
physical experience would be to abolish Africa, or to cease to go
there.

Now this holds good for all other forms of Restlessness. Every other
form and kind of Restlessness in the world has a definite cause, and
the particular kind of Restlessness can only be removed by removing
the allotted cause.

All this is also true of Rest. Restlessness has a cause: must not
