Title: Taking it further: the Design Argument


1
Taking it furtherthe Design Argument
2
Fine-tuned Universe (1)
  • Fine-tuning refers to the surprising precision
    of natures physical constants, and the beginning
    state of the Universe. To explain the present
    state of the universe, even the best scientific
    theories require that the physical constants of
    nature and the beginning state of the Universe
    have extremely precise values. (Biologos)
  • The mere fact that it is enormously improbable
    that an event occurredby itself, gives us no
    reason to think that it occurred by design . As
    intuitively tempting as it may be (Kenneth
    Himma)

Fine-tuned Universe (2)
  • George N. Schlesinger argues what would be your
    reaction to two different events?
  • John wins a one-in-1 billion lottery game. You
    are not immediately tempted to think that John
    (or someone acting on his behalf) cheated.
  • If, however, John won three consecutive
    one-in-1,000 lotteries, you would be tempted to
    think that John (or someone acting on his behalf)
    cheated.
  • Schlesinger argues that the intuitive reaction to
    these two scenarios is epistemically justified
    The structure of the latter event is such that
    itjustifies a belief that intelligent design is
    the cause . Despite the fact that the
    probability of winning three consecutive
    one-in-1,000 games is exactly the same as the
    probability of winning one one-in-1 billion game,
    the former eventwarrants an inference of
    intelligent design.

Fine-tuned Universe (3)
  • While Schlesinger is undoubtedly correct in
    thinking that we are justified in suspecting
    design in the case of winning three consecutive
    lotteries, it is because we know two empirical
    facts about such events.
  • First, we already know that there exist
    intelligent agents who have the right motivations
    and causal abilities to deliberately bring about
    such events.
  • Second, we know from past experience with such
    events that they are usually explained by the
    agency of one or more of these agents.
  • The problem for the fine-tuning argument is that
    we lack both of the pieces that are needed to
    justify an inference of design.
  • Because we lack this essential background
    information, we are not justified in inferring
    that there exists an intelligent deity who
    deliberately created a universe capable of
    sustaining life.

Fine-tuned Universe (4)
  • Antony Flew spent most of his life as an
    atheist, however he later converted to deism
    because of the anthropic principle.
  • He concluded that the fine-tuning of the
    Universe was too precise to be the result of
    chance and so accepted the existence of God.
  • Flew supported the view of Fred Hoyle that the
    universe is too young for life to have developed
    purely by chance and therefore an intelligent
    being must exist
  • Some super-calculating intellect must have
    designed the properties of the carbon atom,
    otherwise the chance of my finding such an atom
    through the blind forces of nature would be
    utterly minuscule . Of course you woulda common
    sense interpretation of the facts suggests that a
    super intellect has monkeyed with physics, as
    well as with chemistry and biology, and that
    there are no blind forces worth speaking about in
    nature. The numbers one calculates from the facts
    seem to me so overwhelming as to put this
    conclusion almost beyond question. (Hoyle)

Argument from improbability (1)
  • Richard Dawkins is critical of theology, creation
    and intelligent design.
  • He believes the chances of life arising on a
    planet like Earth are many orders of magnitude
    less probable than most people would think, but
    the anthropic principle counters scepticism with
    regard to improbability.
  • Fred Hoyle suggested that potential for life on
    Earth was no more probable than a Boeing 747
    being assembled by a hurricane from the
    scrapyard.
  • He argued that a one-time event is subject to
    improbability but that natural selection itself
    is nothing like random chance.

Argument from improbability (2)
  • The argument from improbability, properly
    deployed, comes close to proving that God does
    not exist . The whole argument turns on the
    familiar question Who made God? . A designer
    God cannot be used to explain organized
    complexity because any God capable of designing
    anything would have to be complex enough to
    demand the same kind of explanation in his own
    right. God presents an infinite regress from
    which he cannot help us to escape. This
    argumentdemonstrates that God, though not
    technically disprovable, is very very improbable
    indeed. (Richard Dawkins, The God Delusion)

Argument from improbability (3)
  • Consider the idea that nature itself is the
    product of design. How could this be
    demonstrated? Natureprovides the basis of
    comparison by which we distinguish between
    designed objects and natural objects. We are able
    to infer the presence of design only to the
    extent that the characteristics of an object
    differ from natural characteristics. Therefore,
    to claim that nature as a whole was designed is
    to destroy the basis by which we differentiate
    between artifacts and natural objects.(George
    H. Smith, Atheism The Case Against God)

Argument from improbability (4)
  • Supporters of Intelligent Design, such as W. A.
    Dembski, question the philosophical assumptions
    made by its critics in relation to what a
    designer would or would not do.
  • They claim that such arguments are not merely
    beyond the realm of science but are often
    theological while failing to provide a serious
    analysis of the hypothetical objectives relative
    merit.
  • Some critics, such as S. J. Gould, suggest that
    any purported cosmic designer would only design
    an optimal world, and offer many biological
    criticisms to shows that this ideal is untenable.

10
Argument from improbability (5)
  • As he did not claim to know the objectives of the
    designer, Gould could not say whether the
    designer proposed a faulty compromise among the
    purported objectives.
  • When they are criticising design, biologists
    often stress the functionalities of individual
    organisms and see design as optimal to the extent
    that it maximises these individual
    functionalities.
  • However, the higher-order designs of entire
    ecosystems might require lower-order designs of
    individual organisms if they are to fall short of
    maximal function.
