" That is to say, the condensation of the
nebula as a whole of necessity implies at least the origination of these
new material and dynamical relations among its constituent parts. "As fast
as this heat partially escapes by radiation, further approximation will
take place, attended by further evolution of heat, and so on continuously:
the processes not occurring separately, as here described, but
simultaneously, uninterruptedly, and with increasing activity." Hence the
newly established relations continuously acquire new increments of
intensity. But now observe a more important point. The previous essential
conditions remaining unaltered--viz., the persistence of matter and force,
as well as, or rather let us say and consequently, the law of
gravitation--these conditions, I say, remaining constant, and the newly
established relations would necessarily _of themselves_ give origin to
_new_ laws. For whenever two given quantities of force and matter met in
one of the novel relations, they would of necessity give rise to novel
effects; and whenever, on any future occasion, similar quantities of force
and matter again so met, precisely similar effects would of necessity
require to occur: but the occurrence of similar effects under similar
conditions is all that we mean by a natural law.
Continuing, then, our quotation from Mr. Herbert Spencer's terse and lucid
exposition of the nebular theory, we find this doctrine virtually embodied
in the next sentences:--"Eventually this slow movement of the atoms towards
their common centre of gravity will bring about phenomena of another order.
