an unity to the universe, and
show, within rational limits, how such unity may be physically
conceived, which result will be an advance upon any physical conception
of the universe hitherto manifested or revealed. Further, by accepting
the first of Kepler's Laws in relation to the sun, and admitting the
existence of a central body, we shall be able then to apply the second
of Kepler's Laws, and by so doing shall be able to give a physical
explanation of two scientific facts which up to the present have never
been physically explained, viz. the physical conception of the plane of
the ecliptic, and a physical explanation of the eccentricity of the
earth's orbit, which is but the result of the application of Kepler's
Second Law to the sun's orbital motion around its central body.

ART. 108. _The Sun and Kepler's Second Law._--We will now proceed to
apply the second of Kepler's Laws to the orbital motion of the sun, and,
in so doing, shall find we are able to give at the same time a physical
explanation of the eccentricity of the earth's orbit.

In order to obtain a physical conception of the sun's orbital motion
according to Kepler's First Law, it is essential that we should consider
the effect of the existence of a central body around which the sun
revolves; or, to put the matter into another form, we will ask the
question as to what is the physical cause of the sun revolving round
that central body?

Let us look at the case for a moment. Here, according to astronomical
observation, we find a certain phenomenon which takes the form of a huge
body 865,000 miles in diameter moving through space with a velocity of
nearly 500,000 miles per day. What then is the physical cause of the
movement of this large sphere?

Certainly there must be some physical cause, or else we have a violation
of all experience, which indisputably teaches us that no body moves
unless it is either pushed or pulled. We have, however, done away with a
pulling power so far as the cause of the actual revolution of bodies
around a central body is concerned, and in its place have substituted a
medium that pushes or carries them round each central body. For over 200
years the scientific world has accepted a pulling power, that is, an
attractive power, solely as the cause of the movements of celestial
bodies, with the result that the physical cause of all the motions of
planets and satellites has been outstanding and undiscovered.

It would, therefore
