castle or cathedral ; lie shall raise a monument, or he shall 
build a ship ; and wherever there is most strength and most 
beauty in his production, the most perfect conception, of the 
sphere, is simply and unobtrusively manifested. Is this 
strange ? Not so if we remember that there is not a possible 
movement of the hand from the body that is not included in a 
sphere ; that is to say, every movement, if it were written down 
on paper in lines, would present part of a spherical figure or 
design. 
It remains yet for the philosopher to learn the elementary 
causes of typical divergences from the primitive plan. If the 
sun force gives the primitive impulse as to motion of matter, 
and to form, — and respecting this I think there need be little 
doubt, — there must be either virtually or actually an opposing 
force, which we may call earth force, to keep matter together, 
by which retarding influence variations of form are realized. 
Here for the moment we must rest content. 
Sun force and earth force ! When we know them better in 
their duality or unity, we shall have the key to nature ! Then 
the so-called vitalist, so mysterious, so haughty, so dogmatic, 
so voluminous in words, and so nebulous in fact, will be 
here no more to exalt superstition, and to confound the 
wisdom of the time that is most worth possession, — the 
physical interpretation of the universe.
