Most biologists have believed for over a century that
selection is the sole source of order in biology, that
selection is the tinkerer that crafts the forms. But if
the forms selection chooses among were generated by laws
of complexity, then selection has always had a
handmaiden...If all this is true, what a revision of the
Darwinian worldview will lie before us! Not we the
accidental, but we the expected!

4.1 Darwinism and Scientism The
modern discovery, or rediscovery of the idea of evolution,
was one of the greatest turning points in the development of
human thought. First appearing during the Axial Age, in
Greece and India, then reemerging in the period of the
Enlightenment (note how it follows our non-random pattern),
it begins a complex development in multiple dimensions,
beside its track toward science, from the Kantian philosophy
of history, the teleomechanists, Hegelian Naturphilosophie,
and the embryologists. The work of Lamarck and Erasmus
Darwin foretells the coming of evolutionary science with the
first theories. The marriage of Darwin’s theory to
population genetics will lead in the twentieth century to
the Neo-Darwinian Synthesis.
Lamarck, especially, had
the gist of a true theory of evolution, despite his thinking
about acquired characteristics. But in the next generation,
in the fall-off of the Enlightenment kleiglight we see the
onset of positivism, and the crystallization of Darwinism as
a brand of reductionism.
As in the tale of the blindmen
and the elephant, we find a dialectical field of candidates,
each with a piece of the answer, and then a collapse into an
obsessive reductionism armed with a fragmented piece. The
result is the classic metaphysical deadlock of the Darwin
debate, effectively depriving the public of any clarity or
viable options on the subject of evolution. The sudden
crystallization of positivism reduced science to what is
sometimes called ‘scientism’, the obsessive application of
reductionist universalism to all forms of explanation. This
is part of the mystique of natural selection. The result is,
for example, a disregard of the fact/value distinction. But
if this distinction is essential for understanding
evolution, then a new category of methodological science is
needed.
Darwin’s seminal publication of his
Origin of
Species consolidated the revolution in thought we associate
with ‘evolution’. But this was a highly flawed triumph of
publicity, as the reality of evolution went mainstream. The
resulting theory has left the endless Darwin debate in its
wake, a debate that has become a central feature of modern
culture itself as it downshifts into the conflict of science
and religion. Darwin’s theory of evolution became a defining
moment in the emergence of a distorted pseudo-secularism,
and resulted in the twentieth century opposition of
fundamentalist religious groups whose challenges to Darwin
have grown into a series of skirmishes in a cultural war.
Much of the controversy over evolution predates the work
of Darwin and it was Darwin’s achievement to create an
almost packaged formulation of gestating ideas of evolution,
one that the public was prepared to accept. In many ways,
the real founder of evolutionary science was Lamarck whose
more cogently intelligible, but still inchoate perspective
never survived the radical associations of evolution in the
wake of the French Revolution. Accounts of the history of
biology tend to put the central focus on Darwin, even to the
point of suggesting indirectly that the idea of evolution
was his achievement. But in fact all of the main ideas, even
that of natural selection, preceded Darwin, and the real
source of the new biology was in the period of the
Enlightenment at the end of the eighteenth century, a period
replete with a host of innovations in all fields.
There
is something almost mysterious in the creative career of the
Enlightenment, especially in the last half of the eighteenth
century. This period, which should include the Romantic
reaction, and much else, creates a sort of great divide in
which a whole new culture comes into being. We see the
Industrial Revolution, and the birth of modern capitalism,
the triumph of liberalism in the era of the French and
American Revolutions, a cascade of technical innovations,
and the crystallization of the secular society struggling to
be born since the equally seminal period of the Protestant
Reformation. We have a tendency to produce univalent
descriptions of this rich and many-sided period of bursting
change.
It is significant that the idea of evolution
appeared in concert with the era of the French and
Industrial Revolutions. After the groundwork of figures such
as Linnaeus and Buffon we find the foundations of
evolutionary thought in Lamarck and Erasmus Darwin, the
ancestor of Charles Darwin, first formulating explicitly the
idea of transmutation or development. To see the inherent
ideological character lurking in the idea of evolution, we
can look at the birth of the idea under the specter of
Jacobinism in the wake of the generation of revolution. The
conservatizing Darwin all too obviously fixed the idea of
‘slow evolution’ from its association with ‘revolution’, in
the match with emergent ideologies of classical liberalism,
managing to pass this off as ‘science’.
And then
suddenly the period of reaction set in created by the
turmoil of the revolutionary generation. The period of the
Restoration indirectly conditioned the confusions over
evolution, and the association of the idea with revolution
made the idea highly controversial, even politicized. The
dilemma over slow and fast evolution arises here. The very
idea of progress or revolution was subject to concerted
attacks by the forces of reaction, and this seems to have
delayed the acceptance of evolutionary thought for a full
generation. In fact, it was in many ways Lamarck who first
formulated a theory of evolution, and yet by the end of his
life he was almost a forgotten figure. In the background the
new biology of the embryologists, such as Von Baer and
Geoffrey St. Hilaire, was creating the foundation for a new
conception of evolutionary development.
Then came the
famous
Vestiges of Creation by Robert Chambers whose
immensely popular but anonymous bestseller paved the way for
the work of Darwin twenty years later. In this context we
have a better sense of how Darwin managed to succeed where
these earlier figures had failed, and the conservatizing of
evolution was one of the keys to his success. We can thus
see that Darwin’s theory was successful as an unconscious
reaction to this political background, and the attempt to
fix the idea in association with a triumph of liberalism in
its classical version made for an easy passage at the right
time. This association of the issues with ideology and the
development of modern politics would seem to be irrelevant
to the question of science. And yet it can help us to
uncover the chronic confusion of cultural and biological
evolution that has always been a notable feature of
Darwinian thinking.
The explosive generation of
industrialization, emergent liberalism, and revolution is
the hidden context of Darwin’s theory. Darwin’s social
position and genealogy, scion of the family of Wedgewoods so
prominent at the birth of the industrial revolution in
England, colors his thinking, and his strategy proved to be
brilliant in the way he packaged his theory and timed its
publication. In fact, the curious phenomenon of the delay in
the presentation of a theory that was essentially tabled in
the 1840’s has many different aspects. It was sudden
appearance of the famous Ternate letter of Alfred Wallace
that forced the issue and drove Darwin to make public the
nexus of ideas that he had long kept private, even from many
of his friends and colleagues.
But the idea of evolution
was in the air, always with the built-in ambiguity between
social and biological development. One of the transparent
influences on Darwin’s thinking can be seen in the work of
Herbert Spencer whose views on cultural evolution produced
the classic phrase ‘survival of the fittest’, beginning the
career of ‘traveling concepts’ between evolutionary and
cultural categories of development.
The crystallizing
classical liberalism was a natural companion of Darwinian
theory, and the still more vexacious Social Darwinism
arising in the wake of Darwin’s work springs from this
incestuous constellation of mismatched conceptual themes
claiming the title of evolution. The work of Herbert
Spencer, now a very dated figure, is often made to take the
blame for the Social Darwinist implications of evolutionary
ideology, but these deflections of the essence of the
problem away from Darwin tend to make us fail to see the
ideological core of Darwin’s theory.
The point should be
clear from the direct influence of Malthus on Darwin’s
formulation of his theory. Malthus was the founder of the
science of demography, but he was also a highly contentious
conservative figure, one of the most blatant in his
propensity to use theory for social legitimation. The
polarized and acrimonious debate over Malthus’ work went on
for an entire generation, and in many ways prefigured the
more complex and subtle Darwin debate, still colored with
underground strains of class struggle, revolution, and the
reform bill. It is easy to lose sight of a simple fact: the
mechanism adopted by Darwin under the influence of
Malthusian thinking is open to severe challenge on its own
terms. The struggle of populations, and the incidence of
natural disasters or sudden population fluctuations, is
seldom seen as a very weak candidate for an evolutionary
theory. It is very doubtful if what we mean by evolution is
really caused by anything like a Malthusian scenario.
Certainly the factor of natural selection is a given, but
there is no inherent reason to assume that this generates
the emergence of complex forms that we see in the fossil
record.
The Triumph of Positivism The nineteenth century
produced an immense proliferation of the methods of
scientific reductionism in the biological and social
sciences, as the onset of positivism led the way to a
monolithic consolidation of scientific viewpoints. A
symbolic influence is seen in the figure of Comte, and his
somewhat idiosyncratic Positivism, which influenced Darwin
at the early stage of his career. One of the problems here
is that Comte’s work exhibited its own metaphysical
tendency, and the historicist philosophy of history in which
the Age of Positivism was to succeed those of theology and
metaphysics induced a sense of an irreversible progression
of thought, with the methodology of science in the starring
role.
It is significant that the formulation of
Darwinism and the so-called Age of Positivism followed
directly in the wake of the collapse of the great era of
German philosophy. The end of the reign of Hegelianism,
which began with Kant, was very sudden and the history of
the 1840’s shows us the drama of Feuerbach and Marx
challenging the legacy of idealism and championing the need
for sciences of society. This period produced a clear
delineation of the human and natural sciences, with a
challenge to the reductionist implications of the expanding
scientific revolution. A kind of amnesia has overtaken
science in the stubborn regression, fueled by spectacular,
but misleading, technological wonders, to reductionist
obsessions dressed up in scientific methodological jargon.
It is nonetheless true that Darwinism thrived on this sense
of the epochal transition of modernity attempting to
establish the foundations of a new age of secularism. This
is not an unreasonable view, once its tacit assumptions are
brought out. The problem is Darwin’s selectionist
metaphysics, which cannot sustain the task of defining
secularism. A strong case can be made for the ‘new age of
science’, but this is not something fixed or defined by a
passing phase of evolutionary theory.
In this context the
triumph of the theory of natural selection became a driving
force to legitimate an immense passage of culture across a
threshold but in the process upheld a kind of naïvete about
culture, history, and evolution itself. The mechanization of
the principles of biology under the reductionist
perspectives of positivistic science blinded its champions
to the sudden contraction of thought created by their own
advance. Just as science wished to take over a sudden
narrowing of vision occurred, and the result has produced
many false starts, bogus paradigms in social science, and
the restive underground of puzzled dissenters watching the
triumph of secularism turn into a nest of adders.
The
Coming of Scientism In the wake of the Enlightenment a
contraction of thought occurs, reflected in the emergence of
positivism, and the new brand of science called ‘scientism’,
a reductionist universalism that cannot do justice to
evolutionary realities, as the phenomena of mind,
consciousness and ethics are treated like phenomena of
physics. It is not surprising that the debate lapses into a
debate with religion, given the extreme positions generated
by reductionist oversimplifications. Many warnings emerged
here, from Rousseau and the Romantic Movement to the phase
of German Classical philosophy initiated by Kant.
Is
There a Science of Evolution? The issue of scientism casts
doubt on the status of a science of evolution. The coming of
reductionist thinking in the formation of a science of
evolution was almost a regression from right understanding,
and produced a dumbed-down mechanics almost silly in some of
its extensions. The question has a one-punch knockout: the
failure to take into account the fact/value dichotomy makes
theories of evolution one-dimensional. But we must suspect
an entire dimension is missing in standard theories.
The
Iron Cage The sociologist Max Weber cogently depicted the
onset of scientism in his chronicle of the Iron Cage.
Beyond the public promotion the reality is that Darwinism is
an incomplete account. And the theory of natural selection
has become the keynote for a series of agendas. Some very
obvious issues are ignored in the promotion of a science of
evolution, such as the disregard of the fact/value
distinction, beside the failure to fully account for the
enigma of consciousness, and the agent of human ethical
action, with an intangible element of will.
These issues
should remind us that no real theory of evolution in its
complete form as yet exists. This situation should be common
knowledge, by the testimony of scientists themselves.
Instead we see the constant promotion of reductionist
ideology as a completed science able to resolve all
questions. A kind of religious metaphysics has taken hold,
and the theory becomes the object of a series of agendas.
