6A. What are the four types of intelligent
design?
• The properties of
nature are "just
right" for a wide variety of life-allowing phenomena. For example,
we have sunshine because natural processes produce a fine-tuned balance between
opposing forces, in a cosmic tug-of-war lasting
billions of years. Does this "fine tuning of nature" indicate
a
divine
design
of
nature?
• Christians believe that God
can
change
our situations and our thoughts and actions, and that He responds to prayer. Usually,
all of this happens in a way that appears normal and natural, yet God is actively
involved in a divine guiding of natural process in our daily lives. In
the distant past, maybe God also used this
natural
guidance
during the formative history of nature, to produce desired
natural-appearing results instead of other natural-appearing results.
•• God can also use
miraculous-appearing action. And humans can produce objects and events
that would not occur if we just let nature "do what it does" with
undirected natural process. For
example, if you receive a radio
signal — 2, 3, 5, 7, 11, 13, 17,... — and you think "this
long string of prime numbers probably was not produced by undirected natural
process," you are proposing a theory of Intelligent
Design.
The paragraphs above describe
four types of design, as summarized below.
When scientists study a
feature of nature (a star, bacteria, whale, biochemical system,...) they
can ask about its origin. Was it produced by intelligent design,
either by:
• natural process because,
before history began, the universe was designed so this would
happen, or
• natural process that,
during history, was supernaturally guided in a natural-appearing way to
produce a particular natural-appearing result that was desired, or
detectable design-directed
action during history by a supernatural agent (•)
or a natural agent (•), which was necessary because undirected
natural process would not produce the feature?
Or was there no design
of any type, as proposed by atheists, with everything produced by
natural process that was not designed, was not guided (in an undetectable
natural-appearing way), and was not directed (in a detectable miraculous-appearing
way).

6B. Who
is in the Big Tent of Intelligent Design, and why?
two types
of Intelligent Design, not four?
An atheist rejects the existence
of God, and will therefore reject divine design-action in a design of nature,
a guiding of natural process, or in detectable miracles. They will
affirm only design-action by a natural agent. In fact, this type of
design is accepted by everyone (when there is strong evidence for it) and
it is
obvious in everyday
life when
we wake
up
in a
house, listen to a radio, read a newspaper,
or drive a car.
Based on the Bible, all Judeo-Christian theists should
accept the possibility of all four types of design. But there is
disagreement about the reality when we ask whether one of these (divine
detectable
design-action)
actually was used in the formative history of nature.
For example, proponents of theistic
evolution (who are evolutionary creationists) accept natural-appearing
design — in a design of nature, and a supernatural guiding of natural
events — but they think detectable design-action was not necessary, and
did not occur,
during
formative
history. Even though they propose intelligent design (of
two types) the "big
tent
of
Intelligent
Design" isn't
big
enough for them, since detectable design-action is
the defining characteristic
for what is commonly called Intelligent Design, according to those
in the mainstream "intelligent design" community.
In
the
rest
of
this
page, "design" will
refer to detectable design-directed action, by a natural
agent or supernatural agent. In
most
other
pages
this
is
the
usual
meaning of "design" but it could also refer to the other two types
of design, or all four types, so you'll
have
to
get
the
meaning
from
the
context. Unfortunately, much
confusion occurs due to miscommunication between writers (who don't
clarify their intended meaning, or don't distinguish between different
meanings) and readers.
We'll return to the Big Tent later
in this section, after looking at relationships between design and creationism.
Why is it controversial?
Many theories about design-directed action (involving
radio signals with prime numbers, faces on Mt Rushmore, murder investigations,...)
are evaluated based on their scientific merit, using evidence and logic. But
other design theories are criticized for "not being scientific." Why?
Theories proposing Intelligent Design
can be evaluated using the logical methods of science, are common in science. But
concerns
about design arise when the design-action seems unfamiliar. Sometimes the
action and agent are familiar (as when humans make faces on Mount Rushmore using
dynamite, chisels,...) and in these situations, if there is evidence for design
this inference is accepted by everyone. But
in other cases the design-action is unfamiliar and it might be supernatural. In
these situations the main concerns are religious (but there are also
questions about scientific methods for detecting design, as discussed in Section
7B), and a common claim is that a design theory is a creation theory. Is
this claim justified?
Is intelligent
design just camouflaged creationism?
For any question about design
in any area (radioastronomy, homicide, origins,...) we can view the scientific
inquiry as a two-stage process: first we ask "Was there design-directed
action?", and then we investigate the details. A basic design
theory claims only that design-directed action did occur (the
first stage) but does not try to explain the details (who, why, how,...)
of design-and-production. We should evaluate a design theory
based on what it does claim (that design occurred) instead of what it does
not claim (that it can explain the details).
In origins, a design theory
is not a creation theory. A basic design theory can be supplemented
with details (about the designer's identity and actions, about who, why,
how,...) to form a variety of theories about supernatural creation (by
God or...) or natural non-creation (as in
a theory proposing that evolution on earth was intelligently designed
and directed by space aliens who evolved before us). A basic design
theory — which does not propose divine action, but does acknowledge
this as a possibility — does not try to distinguish between
creation and non-creation. Instead, it just claims that "design-directed
action did occur."
Michael Behe explains: "Most
people (including myself) will attribute the design to God, based in
part on other, non-scientific judgments they have made. ... From a scientific
point of view, the question [who is the designer?] remains open. ...
The biochemical evidence strongly indicates design, but does not show
who the designer was." As a person, Behe thinks
the designer was God. But as a scientist, he thinks "the
biochemical evidence... does not show who
the designer was."
Two Perspectives — Logical
and Sociological
What are the similarities
and differences between design and creation? Logically,
a design theory is not a creation theory, although there is significant
overlap in their scientific claims and in the evidence-and-logic they
claim as support. Sociologically, there are important
connections between design and creation.
Along with Mike Behe, most
advocates of Intelligent Design (ID) think the designer
is
God. Almost
all members of the ID community are mono-theists: mainly Christians, but
also Jews and Moslems. As explained earlier, evolutionary creationists are
excluded — by their own choice, and by the ID community — from
the "big tent" of ID, which includes mainly old-earth progressive
creationists (OECs) and young-earth creationists (YECs).
Most of the
prominent ID leaders think the earth and universe are billions
of years old. But according
to Del Ratzsch, "although
not part of ‘official’ IDM doctrine, some among academic
ID advocates, and the overwhelming bulk of lay ID advocates, accept a ‘young-earth’ version
of creationism," and this is important in a sociological
analysis. Phillip Johnson and other ID leaders have adopted a "big
tent" strategy that welcomes young-earth creationists into
the community of ID. Why? OECs
and YECs agree on the basic claim of ID, that "detectable design-directed
action did occur,"
so they both criticize neo-Darwinist theories
in biology; in addition, OECs and YECs (along with evolutionary
creationists who are outside the tent) both oppose an atheistic worldview.
The
most prominent leaders of YEC harshly criticize all old-earth views,
and — because they acknowledge only two basic views, YEC and Evolution
(which
includes all other views) — they think OECs are deceived by unbiblical
"evolutionary thinking." But the YEC leaders agree with
the anti-Darwinian aspect of ID, so they have formed an uneasy partial
alliance with ID, despite its
tolerance for old-earth views and its lack of emphasis on Genesis.
Each side gains practical benefits
from the alliance. YEC gets a "free
ride" from
design theories that are more scientifically credible, and are less constitutionally
questionable in American
public education. In return, ID can take advantage of YEC support,
sociologically (in the Christian community), financially (in book sales
and contributions),
and politically (for questions about public education,...).
But
a scientific disadvantage for ID is described by William Grassie: "It
is vital that we separate known natural history from the interpretation
of that
natural history. ... Scientific evidence for a long and evolving natural
history of life on this planet has grown dramatically and profoundly in last
two centuries. ... [so] responsible Intelligent Design advocates admit to a long
Earth history. These ID advocates rarely talk about natural history, however,
because they do not want to alienate the Young Earth Creationist who constitutes
the base of their
movement." (11 k

How should we look at the
logical and sociological aspects of Intelligent Design? In my opinion,
• in science every
theory should be logically evaluated based on its scientific merit,
not on the motives of its advocates; a theory of evolution should
not be rejected because some of its advocates are atheists, and a theory
of design should not be rejected because most of its advocates are
theists. According to conventional scientific method, non-scientific
motivations
are
acceptable when a theory is proposed, but "hoping a theory is true
(or false)" should not be a factor
when
a theory
is being evaluated.
• sociological connections
between ID and YEC are mostly irrelevant in scientific debates, because
in their arguments all ID proponents assume a conventional old-earth history
of nature; some assume this because they
think it's true, and others do it "for the sake of argument" so
the focus will be on how rather than when. There are
many similarities in the scientific claims of ID and OEC (and YEC when
the focus is on how, not when, and old-earth history is assumed) and in
the
evidence-and-logic that each claims as support.
• sociological connections
between ID and YEC are very relevant in education, because much
of the enthusiasm (and political pressure) for allowing ID-ideas in public
schools
(*)
comes from people with YEC views, and also because teaching about ID-ideas
might invite "questions about religion" that could draw teachers
into a climate of controversy that most teachers want to avoid; in
American education the situation is complex, with no easy answers, and
is discussed in FAQ-8, What should
public schools teach about origins? (* Leaders
in the
ID community want this to be done indirectly, not by "teaching about
ID" but by allowing criticism of neo-Darwinian theories.)
• sociology of another
type may be relevant for another question: Proponents
of ID rarely publish in science journals or get research funding, but is
this because their work is worthless, or because
the scientific community doesn't want to acknowledge anything worthy in
it? In
journals, I favor a "free marketplace of ideas," but research funding is a more difficult question. { Of course,
similar why-questions, about publishing and funding, could be asked for
young-universe science that I think is not scientifically worthy. }
a bonus question:
Why does
a young-earth view increase the plausibility of evolution?
Prominent young-earth creationists propose a two-model view of origins, insisting
on a choice between
young-earth creation and
all-natural evolution. When we ask "did God design nature so it would be 100% self-assembling by a process of natural-appearing evolution, with no need for miraculous-appearing divine action?",
a two-model view produces an increase in the perceived plausibility
of all-natural evolution, which "wins points" simply because it proposes an old earth. Why? Because
if miraculous-appearing old-earth creation is rejected, so we have only two choices, all evidence for
an old earth (or old universe) becomes evidence for evolution, and evidence
for WHEN has been converted into evidence for HOW.
Ironically, young-earth views increase the plausibility
of evolution in public school classrooms, because: 1) evidence for an old earth becomes evidence for evolution, if "the line is drawn" between an old earth (= evolution) and young earth (= non-evolution); 2) science teachers are less willing to criticize evolution based on scientific evidence and logical evaluation, since they don't want to give credibility to theories about a young-earth (and young-universe) that often have accompanied criticisms of evolution, or they assume that legal prohibitions against teaching young-earth creationism also prohibit any critical questioning of evolution.
