Title: INTELLIGENT DESIGN: A SCIENTIFIC AND RELIGIOUS CRITIQUE
1INTELLIGENT DESIGNA SCIENTIFIC AND
RELIGIOUSCRITIQUE
- I. The Intelligent Design Movement
- II. Evolutionary Biology
- III. Evolutionary Theism
2I. The Intelligent Design Movement
- 1925. Scopes trial in Tennessee upheld
anti-evolution law defended by biblical
literalists. - 1987. U.S. Supreme Court ruled that creation
science (claims of scientific evidence for a
recent special creation) is not acceptable
science but a religious belief, violating
separation of church and state (First Amendment). - 2005. U.S. District Court parents in Dover, PA,
challenge local school board requirement that
students hear a statement about intelligent
design along with the teaching of evolution.
3Nov. 2005. Dover citizens replace school board
members sympathetic to Intelligent Design with
opponents of ID. Dec. 2005. Federal district
judge in Harrisburg rules that ID is not a
scientific theory but a religious belief.
Several school board members had acknowledged
their religious motivations before the
hearings had started. The Dover case has been
settled but ID remains an issue in Kansas and
many other states, either in local school
boards or state boards that set educational
standards.

7ID Claims
- Proponents of ID differ from both biblical
literalism and creation science which were the
subjects of previous court rulings. - They make no reference to the Bible and they
accept a long history of life on earth. - But they insist that some organic structures are
so complex that they could not have evolved by
gradual stages. - Systematic coordination of many parts (e.g. of
the eye) must be the product of supernatural
intervention by an Intelligent Designer.
8- The overwhelming majority of biologists reject
these claims. - For example, the human eye could have evolved by
gradual steps from simpler visual systems like
those in some other species today. -
- ID does not lead to hypotheses that can be tested
experimentally, a key feature of science. - ID does not lead to research papers in
peer-reviewed scientific journals. This cannot be
attributed simply to the biases of the dominant
scientific elite that controls journals.
9Intelligent Design
- Since natural selection can only choose
systems that are already working, then if a
biological system cannot be produced gradually it
would have to arise as an integrated unit, in one
fell swoop, for natural selection to have
anything to act on. Michael Behe, Darwins
Black Box, p. 39

11- A mouse trap would not work if one
part were missing. - Similarly, irreducibly complex systems
only work as a unit. - An intelligent designer must have introduced the
coordinated information, either latently in very
early cells, or later in their subsequent
history. - Reply The idea of a preconceived order neglects
the role of mutations and the organisms
continuing response to a changing environment. - Components serving other functions can be
combined in new ways to serve new functions ( see
Kenneth Miller, Finding Darwins God).

15ID proponents rightly object that some biologists
such as Richard Dawkins defend atheism,
naturalism or materialism as if they were
scientifically proven claims. These are indeed
philosophical interpretations brought to the data
rather than experimentally testable
hypotheses. We can accept methodological
naturalism,which says that science is limited to
studying natural causes, without accepting
philosophical naturalism, which says that nature
is all there is and science is the only path to
understanding (scientism). Explanatory
pluralism suggests that there are a variety of
types of explanation answering differing types of
question in human life.
16Richard Dawkins The universe has precisely the
properties we would expect if there is at bottom
no design, no purpose, no evil, and no good,
nothing but blind, pitiless indifference. Riv
er of Eden, p. 133
17ID proponents rightly say that evolutionary
theory has led to dubious ethical
practices. The survival of the fittest has
been used to justify unrestr- ained capitalism,
colonial domination of inferior races,
and eugenics programs in Nazi Germany (Social
Darwinism). Some sociobiologists claim that
human behaviors can be explained and justified by
their contribution to the survival of our
Paleolithic ancestors. However all these claims
should be seen, not as part of evolu- tionary
theory, but as questionable extrapolations that
ignore the differences between biological and
cultural evolution.
18Gaps in the Evolutionary Account
Creationists once pointed to gaps in the fossil
record, but many of these have been filled in by
transitional forms. To be sure, we do not
understand the origins of life or of
consciousness, much less self-consciousness.
But invoking supernatural intervention would
cut short further scientific inquiry concerning
such questions. In the past, the God of the
gaps has retreated with the advance of science,
so ID is dubious religion as well as dubious
science.
19Evolution is a theory, not a fact
1. Evidence for a long history of descent with
modification from common ancestors is so
overwhelming that it should be considered a fact,
even though the past cannot be observed
directly. 2. The theory that mutations and
natural selection play a central role in
evolution is very strongly supported by a wide
range of disciplines paleontology, physiology,
genetics, embryology, molecular biology, and
immunology (e.g. evolution of antibiotic-resistant
pathogens and new forms of avian flu). The power
of the theory is its relevance to so many
independent fields of inquiry.
203. There are indeed debates among biologists
about the role of other factors, such as
historical contingencies, social structures, or
developmental constraints on possible embryonic
forms, but these debates yield hypotheses that
can be tested before they are accepted as
theories. 4. No theory can be verified with
certainty, but a theory can be falsified by an
accumulation of data that conflicts with it or
(more rarely) it can be modified in a paradigm
shift based on alternative presuppositions (e.g.
Newtonian mechanics replaced by quantum theory
and relativity in very small or very large
structures).
21Support for the ID Movement
Local support has come primarily from evangelical
Christians whose motivations are clearly
religious rather than scientific. Financial
support has come mainly from the religious right
through the Discovery Institute in Seattle, with
which most of the witnesses supporting ID at
recent trials and hearings are affiliated. ID is
seen as an opening wedge for the inclusion of
Christian beliefs in public education.

24The Social Context of Fundamentalism
Secularism, religious pluralism, and alternative
lifestyles and gender roles are seen as threats
to traditional family values. Search for
security in a changing world. Absolutism of truth
claims and moral values in response to what is
seen as all-encompassing relativism. The power
of emotion in religious life has been lost in the
formality and intellectualism of main-line
churches. Compare the growth of fundamentalism
in Islam,fueled not only by nationalism and the
legacy of colonialism but also by confrontation
with modernization and secularization which
threaten traditional values.
25School Board Issues
Local control of school boards. Parents should
decide what they want taught to their children.
Federal courts are out of touch with local
sentiments. Reply promulgation of particular
religious beliefs violates the constitutional
separation of church and state. Science teachers
must draw from and accept the standards of the
wider community of scientists. National
Academy of Sciences (1998) Science is limited
to explaining the natural world through natural
causes. Science can say nothing about the
supernatural. Whether God exists or not is a
question about which science is neutral.
26Media Coverage
The media has presented the two extremes --
people who believe in God but not evolution, and
people who believe in evolution but not God --
as if conflict were inevitable and one had to
choose between science and religion. They have
tended to leave out those who affirm both God and
evolution,or who hold that evolution is Gods way
of creating. Let us look at evolutionary theory
more carefully and then at alternative ways of
relating science and religion.
27II. EVOLUTIONARY BIOLOGY
The Argument from Design before Darwin If you
find a watch on a heath, you know it was the
product of intelligent design and not chance.
Similarly, the coordination of complex structures
in fulfilling useful functions in nature must be
the product of intelligence. Example the many
parts of the eye work together to achieve vision.
See William Paley, Natural Theology
(1802). Darwin The adaptation of complex
structures to useful functions is the result of
the gradual natural selection of such useful
structures in the past, not the result of any
past anticipation of future functions.

33The Challenge of Evolution
- To Biblical Literalism. Reply Many theologians
since St. Augustine have interpreted scriptural
passages metaphor-ically rather than literally.
Since the 19th century, historical scholars have
said that the Bible expressed enduring
theological insights in terms of the
prescientific cosmology of the Middle East.
Fundamentalism and creation science are more
recent views, mainly in the U.S. - To Human Uniqueness. Reply Humans are
descendants of nonhuman ancestors and share many
characteristics with them. But they have
distinctive capacities such as symbolic thought
and language and forms of culture. -
34- The Challenge To Design.
-
- Alternative views of design
- Design of laws only (Darwin)
- 2) Design of initial conditions (Hawking)
- 3) Control of quantum uncertainties (Russell)
- 4) Evolutionary convergence (Conway Morris)
- 5) Emergent levels (Kauffman).
35Charles Darwin I am inclined to look at
everything as resulting from designed laws with
the details, whether good or bad, left to the
working of what we may call chance. . . . I
cannot think that the world as we see it is the
result of chance yet I cannot look at each
separate thing as the result of Design.
Letters to Asa Gray, 22 May and 26 November, 1860
36The Big Bang
What happened at the beginning? A singularity
at t0, a point of zero size and infinite
energy where the laws of physics break
down. Similarities to the biblical account A
beginning of time (rather than a beginning in
time). Creation from nothing (or from a
quantum vacuum)? Initiation of an ordered
irreversible sequence. Fine-tuning of the
physical constants Each of the constants of
the early universe must be within a very very
narrow range for life and consciousness to be
possible (the Anthropic Principle). Is this a new
argument from design?

43Evolutionary Convergence
- Simon Conway Morris, Lifes
Solutions (2003) - Very different lineages converge on similar
solutions - Camera-like eyes evolved independently at least 6
times - Many physiological and behavioral parallels
between marsupial and placental mammals - Similarities in brain structure, communication,
and social structure in dolphins and chimps - Chance is less significant in the outcome when
there are only a limited number of effective
solutions - The constraints of evolution and the ubiquity
of convergence make the
emergence of some-
thing like ourselves a near inevitability.

49An Emergent Hierarchy of Levels
See Ian Barbour, When Science Meets Religion,
Chap. 4. Epistemological Reductionism theories
and laws at higher levels can be derived from
those at lower levels. Ontological Reductionism
lower-level components are more causally
effective than higher-level systems. Causality
acts from the bottom up. Emergence novel forms
of order at higher levels are unpredictable from
theories and laws governing lower-levels.
Top-down Causality systems at higher-levels
influence the boundary conditions of systems at
lower levels without violating lower-level laws.
50Trends in Evolutionary History
- No Simple Directionality blind alleys,
retrogression, extinctions, many directions.
Opportunism adaptation to the immediate local
environment, not to future needs.
More like a sprawling bush
than a neatly organized tree (Stephen Jay Gould). - Overall Trends greater diversity, responsiveness
and complexity (number of significant connections
and levels of organization).
Increase in
capacity to gather, store, and process
information (amoeba, invertebrates, vertebrates,
mammals, apes, humans, cultures). - Causality biologists object when formal or final
causes are substituted for the search for
efficient causes.
51Concepts of Chance
- The intersection of two independent causal chains
each governed by deterministic laws (e.g., the
orbit of an asteroid and the history of
dinosaurs). The future is determined but
unpredictable in practice. - The randomness of some events (e.g., quantum
events amplified through mutations). The future
is open and in principle unpredictable. - In both cases, scientific evidence can contribute
to the narrative of evolutionary history but not
to predicting it from laws.
52Concepts of Design
- Design as preexistent blueprint, a detailed plan.
. This view is threatened by any element
of chance. - Reply death, suffering, and human freedom are
then problematic.Also there are many examples of
imperfect design, such as the blind spot in the
retina of the eye. - Design as general direction toward life and
consciousness, but with no predictable final
state. A biofriendly universe. Both chance and
law have a role in the outcome. - Necessary features of an evolutionary world
death (successive generations) and suffering
(from competition). - God endowed matter with diverse potentialities
and propensities, including the possibility of
human freedom.
53III. EVOLUTIONARY THEISM
- Natural Theology the attempt to prove the
existence of God from features of nature, e.g.,
the argument from design. - Theology of Nature the attempt to view features
of nature from within a religious tradition based
on the religious experience of a historical
community. - Religion in Human Life ritual, meditation, the
healing of brokenness in individual and social
life, ethical norms. For Christians, response to
the life and death of Christ. - Traditional beliefs can be reformulated in the
context of the religious community in the light
of science.
54- The Limitations of Science every science is
selective, using limited concepts to understand
particular aspects of experience. - Meta-questions why is there a universe at all,
why does it have the order it has, why is it
intelligible to the human mind? Questions raised
but not answered by science. - Doctrines as relationships creation, fall,
redemption, fulfillment are not a sequence of
events but enduring characteristics of the
relation between God and the world.
55Science and Religion as Distinctive Domains
- Science asks about regularities among events in
nature. Empirical inquiry in the interest
of prediction and control. - Religion asks about ultimate meaning and purpose.
A way of life expressed in the rituals,
stories and practices of a community. - Analytic Philosophy claims that differing
language systems have differing and independent
functions in human life. - However, science and religion do sometimes
influence each other. Our understanding of nature
affects our view of Gods relation to nature. - Five models of Gods action through the
structures of nature rather than by supernatural
intervention in violation of the laws of nature
561. Primary and Secondary Causality
- God as primary cause works through the secondary
causes that science investigates (neo-Thomism). - Primary causality is a different order of
explanation, answering questions unlike those
that scientists ask about relationships between
natural events. - God is radically transcendent, not another cause
like natural causes. - The integrity of the created order and the
integrity of science are preserved (William
Stoeger). - Nature is a developmental economy without
deficiencies requiring later intervention
( Howard van Til).
572. God as Communicator of Information
- Information an ordered pattern in a sequence of
elements (DNA, computer digits, letters, sounds). - Communication of information occurs when another
system responds selectively (cell, computer,
human person). - Meaning of the message is not contained in the
sequence itself but is dependent on a wider
context of interpretation.
58- Gods action as an input of pure information.
Selection among possibilities in chaotic
processes (John Polkinghorne). - Divine Word as rational principle (Greek logos)
and as creative power (Hebrew). - The meaning of the message is discernable only
in a wider context of interpretation. - For Christians, the message of creation is seen
in the person of Christ (the Word made flesh)
but also in the created order.
593. God as Top-down Cause
- An extension of the idea of top-down causality
between levels in the world (Arthur Peacocke). - Upper levels produce constraints or boundary
conditions on lower levels without violating
lower-level laws. - Chance and law together are creative and
expressive of open-ended design. - Gods purposes are communicated through the
patterns of events, expressing intentions but not
a predetermined plan. - Christ is a mode of Gods self-expression,
revealing Gods nature to us.
604. Gods Self-Limitation (Kenosis)
- Between the omnipotent God of classical
Christianity and the inactive God of Deism
(Nancey Murphy George Ellis). - Gods power is not omnipotent control but the
empowerment of other beings. - An incomplete cosmos still coming into being.
- The cross shows a God who participates in
suffering and transforms it through redeeming
love. - Compare feminist critiques of male
images of coercive power (both
in human
relations and in Gods action).
615. Process Theology
- Reality as a dynamic web of momentary events, not
a collection of enduring self-contained objects
(Alfred North Whitehead). - Rejects mind-matter dualism and materialism.
Defends a two-aspect monism in a hierarchy of
organizational levels. - All integrated entities have objective and
subjective (experiential) features in varying
degrees, but only higher-level organisms are
conscious. - To every entity God presents new possibilities
with open alternatives,
eliciting its response. - God is the ultimate source of both order and
novelty, but the entity
itself selects among
alternatives.
62- An unfinished universe showing order and disorder
is compatible with the biblical message of
promise and hope but not with the idea of
completed design (John Haught). - A God of self-limiting love allows creaturely
creativity in the emergence of new forms of
order, relationality, and inclusive community. - Gods participation in the suffering of the world
contrasts with Gods detachment in Deism. - Promise and hope point toward the future rather
than the past.
63The Biblical View of the Holy Spirit
- As God active in both nature and human life.
- The earth was without form and void, and the
darkness was upon the face of the deep, and the
Spirit of God was moving over the face of the
waters (Genesis 12). - Plants and animals When thou sendest forth thy
Spirit, they are created (Psalm 10430). - Inspiration of the prophets (Ezekiel 115).
- Worship Take not thy Holy Spirit from me
(Psalm 5111). - Christ received the Spirit at his baptism (Mark
110). - His followers were empowered by the Spirit (Acts
2).
64 - The role of the Spirit in nature, religious
experience, and the life of Christ offers a
common framework for creation and redemption,
which are often contrasted. - Come, Holy Spirit, renew thy whole creation.
Theme of World Council of Churches 1991

65Conclusion
In a Theistic Framework Order includes
lawfulness without excluding novelty,
creativity, and contingency. Purpose can be
expressed in open-ended design, but
intention and agency are needed to avoid
Deism. Human Responses To a Universe of Chance
pessimism or courage in facing
meaninglessness search for security. To a
Universe of Law resignation, alienation from
an impersonal cosmos. To a Universe of
Design gratitude, trust, hope. We can accept
many biblical affirmations today, even though
our cosmology is very different. Images
