The Darwin debate revolves around the claims and
definitions of naturalism. The project of science is the discipline of
methodological naturalism. We can certainly embrace naturalism, but its
definition cannot prejudge the issue of what nature itself shows to be the case.
We are stuck with the obstinate Cartesian legacy of dualism, leaving our
naturalistic assumptions schizophrenic. Religious critics then proceed to the
opposite confusion of spiritualizing the leftovers at the limits of
reductionism. The glaring lack of any account of the evolution of consciousness
ought to have made Darwinian certainties close to preposterous, but it is
assumed in advance that some scenario of adaptation can account for this.
Even as Darwinism challenges the legacy of metaphysics, its
claims for evolution are forced to impinge on this realm with tacit assumptions
that belong to the same genre. The problem is, first, the complexity of the
organism, and its intangible mysteries such as the nature of the 'will', if such
exist, in the human evolutionary development of ethical behavior.
If we invoke science we should recall its history, and the
moment of the scientific revolution in the seventeenth century. Descartes not
only founds the science of analytic geometry, he creates his famous dualism of
body and consciousness. This dualism is forever rejected, but never transcended,
although the appearance of Spinoza produces a new perspective on the question
that will be the undercurrent of a classic Enlightenment debate. Newton,
beside his great achievements in physics, nonetheless exempts the human will
from his dynamics. In the wake of Rousseau, it is the figure of Kant, beside
Hume, who, embracing the system of Newton, formalized a more refined version of
this dualism, in a classic gesture arising during the so-called crisis of the
Enlightenment. And it is significant that Kant stands at the dawn of the rise of
evolutionary biology, with a set of critiques that can mediate the
contradictions of causality, freedom, and teleology, especially in the
analytical study of organisms. The onset of the positivistic period completely
bypasses this important stage in the development of the modern social and
biological sciences.
It is not surprising, and yet remarkable, therefore
that the work of the philosopher Kant is too little considered in the
dialectical collisions of science and religion, since his system of philosophy
addressed wholesale the problematic that pervades not only the philosophies of
rationalist theology, but of the empiricist tradition as well. In fact,
positivism is a form of collapsed Kantianism and it is a pity that scientific
methodology, mostly through reductionist downshifting, has lost his analysis of
the boundaries of science.
In essence the question is simple. The need for a 'science
of metaphysics' is the first step to a 'science of history and/or evolution'.
But it is just this requirement that proves the stumbling block. In the
preface to his famous first critique Kant isolated the three great issues of the
metaphysical tradition destined to get into trouble on the way to a 'science of
metaphysics': that of divinity, followed by those of soul and free will. To
these we should add the question of teleology, and note the way Kant
considered teleology within the bounds of methodological naturalism, albeit
ambiguously. The questions of divinity, soul, and free will demand proofs of
existence, and Kant exposed the way that the road to these three proofs is beset
with contradictions. They are metaphysical because they stand beyond the
empirical.
The important issue here is that while we can easily agree,
for example, that a 'soul' question (there are a multiplicity of such) is
metaphysical, we might forget that its antithesis, the negation of the existence
of soul, is equally metaphysical. The very term 'existence' is unclear in this
case. The possibility that definable 'soul' has a reality but is beyond the
possibility of knowledge would prove a severe check to a theory of the organism,
and, unfortunately, that is just where Darwinian theory is going wrong. We can
easily predict, then, that a theory such as Darwin's will become ambiguous on
these three issues, even as it has banished the fourth. There can be no
mystery to the Darwin debate. Each of these questions enters into the ambiguity
of evolutionary theory. We see Darwinists attempting to claim that free will
rises in the context, once again, of natural selection, and adaptation, a very
peculiar approach, one with no evidentiary basis. We should demand the
strictest evidence of this, and we rapidly discover just how difficult
demonstration would prove there. We need a much broader approach.
We notice immediately that the conflict of science and
religion, notably Darwinians and fundamentalists, impinges on the first, soon
followed by the second, the third creating a dilemma even in the context of
secular culture. The monotheistic religions have shown an obsessive reluctance
to yield ground on the issue of divinity in history, hence evolution. The
Eastern religions have not yielded an inch on the question of 'soul' (although
Buddhism gives the misleading appearance of rejecting the idea of ‘soul’),
would grant the problematic shown by Kant, yet demonstrate methods of enquiry
into issues of self. And the core concepts of modernity, its definitional
liberalisms, are equally problematical in relation to the causal monism of the
defining scientism of the modern era.
The principle of freedom shows ironically the way in which
secular thought is entangled in metaphysical ambiguity as much as the
religionist, and this idea creates a more subtle version of the drama of theists
and atheists. For the will to freedom soon shades into the hopeless quagmire of
the 'will of god'.
Intelligent design The current
design challenge to Darwinism offers no relief or clarification of the problems
with Darwinism. Note that the design argument is perched ambiguously between the
question of monotheistic divinity and some obscure polytheistic 'will to
design'. The question of supernatural teleology lurks in mix. Kant and Hume
produced some classic (attempted) refutations of the design argument, which is a
variant of our first metaphysical barrier, the divinity proof. The design
argument has the same problem as natural selection: proper verification.
The concept of freedom, behind that of free will, is
indispensable for the proper discourse of secularism itself, with its defense of
freedom and autonomy. We can proceed in an indirect way by looking at the
historical phenomenon of freedom with or without the far more elusive proof of
the existence of 'free will'.
Freedom evolving It is not
necessary to assume the existence of free will to posit an ‘evolution of
freedom’, since the evolving system might show ‘evolving toward’ rather
than ‘result achieved’. Any
such system will provoke a paradoxical question, What causes freedom? This
question was directly addressed by Kant. We must distinguish the macro and micro
aspects of ‘freedom evolving’,
a strange complication that will in fact lead to the solution of the problem.
And it might be the case that as observers looking backward we are still
short of the final stage. So we
need not assume ‘free will’ as yet in the observer, able to document earlier
stages of evolution.
We can adopt a double strategy, simply introducing an 'idea
of freedom' as an extra axiom, to be used for empirical study of the history of
freedom, and/or creating an explicitly dualistic model that learns to live with
a contradiction. We will also have still another tactic, a surrogate for 'free
will', which we will call 'self-consciousness', which can be taken with
chameleon neutrality as either in the causal category, or in the freedom
category.
But Kant's thinking enforces a severe discipline of the
limits of our knowledge on these questions, and, this being the case, we can see
that while the affirmation of a thesis on divinity is taken as metaphysical, its
negation is destined to suffer a similar fate. We can see at once that, if Kant
is right, then the theory of natural selection, the spearhead of much secular
thought in a post-religious mode, is forced into a task that it cannot fulfill.
As we proceed to examine history in the light of evolution
we might, since our task is a fairly straightforward one of demonstrating an
empirical pattern, restrain explicit assumptions on all three of these
assumptions. Kant's first critique can be approached in many ways, one of
them being simply the question of the 'antinomies' that infest our processes of
reason. The classic Third Antinomy expresses the problematic of evolution and
ethics directly:
Kant’s Third Antinomy The crux
of the contradiction pervading evolutionary and ethical ideas is posed in the
classic ‘Dialectic
’ of Kant’s first Critique. “Causality according to laws of nature is not
the only kind of causality from which the phenomenon of the world can be
derived. It is necessary, in order to explain them, to assume a causality
through freedom.” Its antithesis is: “There is no freedom: everything in the
world takes place solely in accordance with laws of nature.”
These antinomies are posed in the form of a debate whose
thesis and antithesis are both established by logical argumentation, provoking a
dilemma that can only be resolved by a transformation of our basic perspective
on space, time, and the representation of them in our commonsense perspectives.
But if we take the simple duality of the statement of the antinomy directly as
given in the starting point of observation and reflection we can see that our
questions about evolution and ethics are simply variant confusions of Kant's
dialectic. That the question ‘What causes freedom’ suffers ‘logical
collapse’ requiring a new language is no final objection to this approach. Our
difficulty with the depiction of the evolutionary agent rises from the way in
which we take the antithesis given by Kant as the sole mode of explanation. It
is entirely problematical to be bringing in two forms of causality, but the
dilemma is there, that we cannot reduce the potential of freedom to the level of
causality and produce an account of evolutionary ethics. That this issue should
prove the clue to any theory of evolution as such will become clear as we
proceed.
One of the earliest stages of the confusion over evolution
lay in the conflict with the outstanding 'Nature Philosophy', especially the
Hegelian version that was influential at the beginning of the nineteenth
century. This reaction to the great foundation created by Kant has obscured his
contribution, which is very well adapted to the needs of science. The sudden
collapse of this tide of idealism, so visible in the generation of Feuerbach and
Marx, left its mark on evolutionary thought as it absorbed the influences
of Comte and the new positivism. But even as it embraced this rejection of
metaphysics Darwin's theory of natural selection unwittingly adopted a
metaphysical stance of its own. This springs from the totalizing character of
the theory, which is required to reduce all organismic phenomena to scenarios of
adaptation. That is not a realistic research project.
Transcendental idealism Lost in
the progression of modern philosophy, next to the emergence of positivism, is
the Kantian tour de force, transcendental idealism, a unique hybrid (with
a misleading terminology) of causality/freedom issues, and easily taken as a
superset of standard scientific thinking. The ‘positivism done right’ allows
us to restate, if not fully solve, the issues of human action and scientific law
in a workable form.
Despite the endless theological controversies over
evolution, Darwinists, by and large, with important exceptions, tend in fact to
adopt a proper stance on the issue of divinity. Darwin's theory merely wishes to
explore the naturalistic implications of evolution without ad hoc theistic
explanations. This is not a commitment to atheism, or some claim to have
disproved the existence of god, but simply the perception that the data of
evolution strongly suggest a naturalistic interpretation. And this approach has
proven fruitful indeed. However, it is true that many Darwinists attempt to
extend this formulation to use natural selection as argument in favor of hard
claims on theistic issues. This is not in itself illegitimate but, by and large,
simply creates a new metaphysical myth, and an egregious ambition that simply
provokes the dialectic ad infinitum that we see in the history of Darwinism.
Questions of soul are the real nemesis of Darwinism. These
are the most insidious, because materialism overwhelmingly tends to the negation
of the soul idea. This should not be confused with the 'soul beliefs' espoused
by monotheists. Such beliefs are as open to challenge as any religious doctrine,
in a secular age. But this is tantamount to a declaration of the non-existence
of soul, crossing the tripwire of metaphysical claims.
Buddhism/Hinduism The ambiguity
of the term ‘soul’ is highlighted in the religions of the Indic stream where
the object of religion is to transcend the ‘soul’ taken as an envelope of
natural man, an aspect of his self within nature. Soul is an aspect of nature,
although beyond our immediate psychological introspection.
The question of 'soul' is very provocative, and it is more
fruitful simply to think in terms of the organism, and its definition. Is the
organism a purely space-time entity, or does it have a complex dimensionality?
This issue is especially vexacious because it suggests that we cannot properly
observe the organism at all. But this then preempts any theory in closed form.
We might consider the bare minimum issue here, the distinction of computer and
computer program, to see that such issues resemble those of mathematical
Platonism, for example.
Transcendental Deduction A
classic moment in Kant's thinking is the attempt to infer something beyond the
boundaries of the temporal/causal in the realm of self. This deduction (which is
a legal term with another meaning, and not a proof) tries to infer a something
that in integrating experience must stand beyond experience. We will not pursue
this here except to note that the term 'transcendental' is not the same as
'supernatural' and is distinguished from 'transcendent'. A crucial issue here is
that our intuitive sense of self is a represenation of a noumenal reality beyond
our sensibility and understanding. We must confront the problematic possibility
that the 'core self' of man, or indeed of the organism, is beyond knowledge, a
disastrous possibility for evolutionary theories. And theory of adaptation fails
at once if the 'core self' has no spatial or temporal extension.
