Fig. 14.2 A triadic definition of evolution. It is suggested here that Y is related to Firstness, X to
Secondness, and Z to Thirdness in the triadic metaphysics of C. S. Peirce (1839-1914) (Sect.
6.2
)
.
This figure is qualitatively similar to Fig.

type
with its
tokens
in physics, biology, and the spiritual
world. The symbols X, Y, and Z are defined in Statement 14.17 and Fig.

It should be noted that
Evolution
is represented by the whole triangle (see the
square brackets) and
Emergence
by one of its three edges, that is, Y-X. As indicated
in Table
14.8
below, physical evolution differs from biological one because their
mechanisms of evolution are different - one is cosmological in spatiotemporal scale
and the other is local, that is, earth- and biosphere-bound.
Laughlin's treatment of the concept of
evolution
in the above quotations appears
to go against the mainstream view of contemporary biologists (Salthe 2009).
Theodosius Dobzhansky (1900-1975) (1973) has remarked that
Nothing in biology makes sense except in the light of evolution.
(14.19)
To a physical-organic-chemist-turned theoretical cell biologist who has spent
more than three decades studying living systems, Statement 14.18 rings true. More
recently, Fodor and Piatelli-Palmarini (2010, p. 30) expressed what they thought
was the opposite of Statement 14.18:
...
nothing in evolution makes sense except in the light of developmental biology.
