Title: Betty
1Betty Cordell a new design argument
- Betty Cordell offer two arguments, or two
stages of one argument - First - based on the Big Bang theory the
Anthropic Principle - The Anthropic Principle was first proposed by
Robert Dicke (Princeton) in 1961
2Betty Cordell a new design argument
- The Anthropic Principle A universe capable of
evolving systems as complicated as life and
humans must have a delicate balance in the
structure of its fundamental forces and special
initial conditions (Polkinghorne, One World The
Interaction of Science and Theology, 1986).
3Betty Cordell a new design argument
- Or another statement of it If the universe were
different in any significant way from the way it
is, we would not be here to wonder why it is the
way it is.
4Betty Cordell a new design argument
- Some illustrations of the fine-tuning of the
universe. - The expansion rate. Stephen Hawkings If the
rate of expansion one second after the Big Bang
had been smaller by one part in a hundred
thousand million million it would have
recollapsed before it reached its present size
(quoted in Barbour 204).
5Betty Cordell a new design argument
- The formation of the elements. If the strong
nuclear force were slightly weaker we would have
only hydrogen in the universe. If the force were
slightly stronger, all the hydrogen would have
been converted to helium. In either case, stars
and compounds such as water could not have
formed.
6Betty Cordell a new design argument
- If the nuclear force had been slightly stronger,
carbon would all have been converted into oxygen.
7Betty Cordell a new design argument
- This is a new design argument for the existence
of God. (What were the old design arguments?) - Betty Cordell, John Polkinghorne, John Leslie
argue, on the basis of this fine-tuning of the
evolution of the universe (the anthropic
principle), propose that, given a universe which
has evolved by chance and one designed by a an
intelligent designer, the latter is more
probable.
8Betty Cordell a new design argument
- Some objections (raised by Betty Cordell)
- Perhaps intelligent life could have evolved in a
different way, without hydrogen water. We are
viewing ourselves too anthropocentrally. - Perhaps there are an infinite number of universes
existing alongside of each other. Given enough
universes, the probability of one producing life
is high.
9Betty Cordell a new design argument
- Betty Cordells reply
- These are logical possibilities but there is no
empirical evidence to support them.
10Betty Cordell a new design argument
- The 2nd argument (or 2nd half of the above
argument) - Argue that the probability of the evolution of
complex biomolecules (e.g., enzymes, DNA, RNA)
is infinitesimally small. - General conclusion The anthropic principle
the evolution of complex biomolecules supports
the existence of an intelligent designer.
11Betty Cordell a new design argument
- Cautions (not in Betty Cordell)
- 1. Perhaps in the future, scientific theory will
be able to explain the remarkable fine-tuning of
the evolution of the universe the evolution of
complex biomolecules. (See Barbour 207-09) The
danger of a God-of-the-gaps argument. - Betty Cordells response The gaps are
becoming more resistant to scientific
explanation.
12Betty Cordell a new design argument
- 2. Robert Russell Any cosmology is compatible
with the Christian notion of creation because the
latter is not about origins but dependence.
13Betty Cordell a new design argument
- 3. Ernan McMullin Big Bang is still relevant
to God. What one could say . . . is that if the
universe began in time through an act of a
Creator, it would look something like the Big
Bang. What one cannot say is that the Big Bang
model supports the Christian doctrine of
creation. The Big Bang theory is consonant with
belief in God the creator.
14Betty Cordell a new design argument
- Final comment on this new design argument
- Note that the argument is not an argument for God
as the initiator of t 0, that God is the being
who got it all going (Pope Pius XII (1952)
physicist Robert Jastrow (1978)). - Rather the argument is that God must exist an an
adequate explanation of the fine-tuning of the
evolution of the universe.
