itive Impulse, as I believe it is supposed to
do, then to that extent it is not conformable to the principles of our
Philosophy, as embodied in the rules given by Newton.

Simply because, while it supposes a source or origin of its activity at
the first, it goes on to suppose a continuance of that activity, without
recognizing a continuing source or cause. It only recognizes and
supposes the one original impulse given at the beginning, to account for
the cause of the continually existing, and exerted power of the
Centrifugal Force. I do not for a moment suggest, that the Divine
Creator of all things, and the Ordainer and Upholder of all powers,
forces and laws could not, had He chosen to give such a force, have
given it and for ever operating. With that aspect of the question I have
nothing to do, and of it nothing to say. I am dealing, and only wish to
deal, with scientific facts, and scientific teaching from the purely
philosophical standpoint.

Such an idea of a continuing effect, without a continuing cause, is
altogether opposed to experience and observation, and is a violation of
the second Rule of Philosophy.

Look where we will, or at what we will, and not only effects and causes
are seen on every side, and in every thing, linked together inseparably,
but wherever, and in whatever phenomena there is found a continuance of
effect or effects, there is always and without exception found also a
continuing source or cause.

Wherever Nature, therefore, gives us a continuous effect of any kind or
sort, she always gives us a continuing cause, that can be both proved
and demonstrated to exist. Nowhere in Nature, amid all her powers,
principles and laws, is there to be found an effect without a cause, and
in all continuing effects, a continuing and perpetuating cause also, and
that effect exists just as long as the cause exists.

If the effect is perpetual, then the source and cause is perpetual also,
both in its existence and energy. Hence if the Centrifugal Force
embodies the idea of continuance of the Primitive Impulse, without
showing how that Primitive Impulse is continued, then such an idea is an
anomaly in the universe, is altogether opposed to the teaching of Nature
and science, and violates the most fundamental principles of our
Philosophy.

The philosophic explanation, therefore, of the Centrifugal Force, is
that Force which flows from a centre, and _which is the exact opposite
and counterpart of the Centr
