Hoe interpreteren we de natuur?:

Natuur Theologie:• Paley – Newman – Barth …..

• The fundamental thesis of the book is that if nature is to disclose the transcendent, it must be "seen" or "read" in certain specific ways -- ways that are not themselves necessarily mandated by nature itself. It is argued that Christian theology provides a schema or interpretative framework by which nature may be "seen" in a way that enables and authorizes it to connect with the transcendent.

• --- A. McGrath p x about "the Open Secret"

tapestry arguments in biology: evidence from the human

genomeChromosome 2 is unique to the human lineage of evolution, having emerged as a result of head-to-head fusion of two acrocentric chromosomes that remained separate in other primates. The precise fusion site has been located in 2q13−2q14.1 (ref. 2; hg16:114,455,823−114,455,838), where our analysis confirmed the presence of multiple subtelomeric duplications to chromosomes 1, 5, 8, 9, 10, 12, 19, 21 and 22 (Fig. 3; Supplementary Fig. 3a, region A). During the formation of human chromosome 2, one of the two centromeres became inactivated (2q21, which corresponds to the centromere from chimp chromosome 13) and the centromeric structure quickly deterioriated [42].

Tapestry arguments in biology

For some physicists, mathematicians and engineers -- these arguments may still seem foreign and vague; It doesn’t “smell” like the scientific method they are familiar with-- for example: where is the repeatability? What is the predictive power of these arguments? Where are the numbers?

Dawkins en atheisme van de gaten?

• "The individual organism ... is not

fundamental to life, but something that emerges when genes, which at the beginning of evolution were separate, warring entities, gang together in co-operative groups as "selfish co-operators". The individual organism is not exactly an illusion. It is too concrete for that. But it is a secondary, derived phenomenon, cobbled together as a consequence of the actions of fundamentally separate, even warring agents.

• From Richard Dawkins, Unweaving the Rainbow, (Penguin, London, 1998) p 308.

Contingency v.s.``deep structures’’: Re-run the tape of evolution?

“Wind back the tape of life to the early days of the Burgess Shale; let it play again from an identical starting point, and the chance becomes vanishingly small that anything like human intelligence would grace the replay.” In evolution, there is no direction, no progression. Humanity is dethroned from its exalted view of its own importance

S.J. Gould: “Wonderful Life”; (W.W. Norton 1989)

When you examine the tapestry of evolution you see the same patterns emerging over and over again. Gould's idea of rerunning the tape of life is not hypothetical; it's happening all around us. And the result is well known to biologists — evolutionary convergence. When convergence is the rule, you can rerun the tape of life as often as you like and the outcome will be much the same. Convergence means that life is not only predictable at a basic level; it also has a direction.Simon Conway Morris “Life's Solution: Inevitable Humans in a Lonely Universe”; (CUP, 2003)

During the formation of human chromosome 2, one of the two centromeres became inactivated (2q21, which corresponds to the centromere from chimp chromosome 13) and the centromeric structure quickly deterioriated [42].

tapestry arguments in biology

“But others [biologists], I soon came to realize, regarded logical arguments as suspect. To them, experimental evidence, fallible as it might be, provided a far surer avenue to truth than did mathematical reasoning. .... Their implicit assumption seemed to be: How could one know one’s assumptions were correct? Where, in a purely deductive argument, was there room for the surprises that nature might offer, for mechanisms that might depart altogether from those imagined in our initial assumptions? Indeed for some biologists, the gap between empirical and logical necessity loomed so large as to make the latter seem effectively irrelevant.

Aside:Emergence of Humans?

Advice from C.S. Lewis

When the author of Genesis says that God made man in His own image, he may have pictured a vaguely corporeal God making man as a child makes a figure out of plasticine. A modern Christian philosopher may think of the process lasting from the first creation of matter to the final appearance on this planet for an organism fit to receive spiritual as well as biological life. Both mean essentially the same thing. Both are denying the same thing -- the doctrine that matter by some blind power inherent in itself has produced spirituality. (C.S. Lewis, God in the Dock Eerdmans (1970), p 46)

Advice from Billy Graham "I don't think that there's any conflict at all between

science today and the Scriptures. I think that we have misinterpreted the Scriptures many times and we've tried to make the Scriptures say things they weren't meant to say, I think that we have made a mistake by thinking the Bible is a scientific book. The Bible is not a book of science. The Bible is a book of Redemption, and of course I accept the Creation story. I believe that God did create the universe. I believe that God created man, and whether it came by an evolutionary process and at a certain point He took this person or being and made him a living soul or not, does not change the fact that God did create man. ... whichever way God did it makes no difference as to what man is and man's relationship to God.”

Writers of “the Fundamentals”

• One of the original “Fundamentalists”• There is not a word in the Bible to indicate that

in its view death entered the animal world as a consequence of the Sin of man.

• When you say there is the “six days” and the question whether those days are meant to be measured by the twenty-four hours of the sun’s revolution around the earth -- I speak of these things popularly. It is difficult to see how they should be so measured when the sun that is to measure them is not introduced until the fourth day. Do not think that this larger reading of the days is a new speculation. You find Augustine in early times declaring that it is hard or altogether impossible to say what fashion these days are, and Thomas Aquinas, in the middle ages, leaving the matter an open question.

The Bible and Science

The lesson of Galileo, …, should remind us that careful observation of the natural world can cause us to go back to Scripture and reexamine whether Scripture actually teaches what we think it teaches. Sometimes, on closer examination of the text, we may find that our previous interpretations were incorrect.•Wayne Grudem, “Systematic Theology” IVP (1994) p 273

Wayne Grudem

Page 81: Een fysicus over de kosmos, de aarde en het leven Dr. Ard Louis Department of Physics University of Oxford   .

The Bible is not a science textbook

• The whole point of scripture is to bring us to a knowledge of Christ --- and having come to know him (and all that this implies), we should come to a halt and not expect to learn more. Scripture provides us with spectacles through which we may view the world as God’s creation and self-expression; it does not, and was never intended, to provide us with an infallible repository of astronomical and medical information.

Advice from Schaefer

• We must take ample time, and sometimes this will mean a long time, to consider whether the apparent clash between science and revelation means that the theory set forth by science is wrong or whether we must reconsider what we thought the Bible says.

Warfield on evolution

• B. B. Warfield (1851-1921). A biblical inerrantist as evolutionist. Livingstone DN, Noll MA, 1: Isis. 2000 Jun;91(2):283-304.

• The theological doctrine of biblical inerrancy is the intellectual basis for modern creation science. Yet Benjamin Breckinridge Warfield of Princeton Theological Seminary, the theologian who more than any other defined modern biblical inerrancy, was throughout his life open to the possibility of evolution and at some points an advocate of the theory. Throughout a long career Warfield published a number of major papers on these subjects, including studies of Darwin's religious life, on the theological importance of the age of humanity (none) and the unity of the human species (much), and on Calvin's understanding of creation as proto-evolutionary. He also was an engaged reviewer of many of his era's important books by scientists, theologians, and historians who wrote on scientific research in relation to traditional Christianity. Exploration of Warfield's writing on science generally and evolution in particular retrieves for historical consideration an important defender of mediating positions in the supposed war between science and religion.

Page 87: Een fysicus over de kosmos, de aarde en het leven Dr. Ard Louis Department of Physics University of Oxford   .

What is ID• Intelligent agency, as an aspect of scientific theory making,

has more explanatory power in accounting for the specified, and sometimes irreducible complexity of some physical systems, including biological entities, and/or the existence of the universe as a whole, than the blind forces of. . . matter.’[1] That is, intelligent design is a better explanation for entities exhibiting complex specified information (CSI) than are appeals to the inherent capacities of nature (i.e. chance and/or physical necessity). ID suggests that the world contains objects that exhaust the explanatory resources of undirected natural causes, and can only be adequately explained by recourse to intelligent causation.

• (definition from Peter S. Williams)

Page 88: Een fysicus over de kosmos, de aarde en het leven Dr. Ard Louis Department of Physics University of Oxford   .

Irreducible Complexity

This result is so unambiguous and so significant that it must be ranked as one of the greatest achievements in the history of science ... The discovery [of intelligent design] rivals those of Newton and Einstein, Lavoisier and Schroedinger, Pasteur and Darwin.”

Calvin on using science• As far as I am aware, there is no evidence that Galileo had any direct knowledge of Calvin's writings.

Nevertheless his understanding of the nature of the language used by the Bible when referring to the natural world is the same as Calvin's as the following quotations from the Letter to the Grand Duchess Christina show.

• B1. These propositions set down by the Holy Ghost were set down in that manner by the sacred scribes in order to accommodate them to the capacities of the common people, who are rude and unlearned. (p. 181)

• B2. It is necessary for the Bible, in order to be accommodated to the understanding of every man, to speak many things which appear to differ from the absolute truth so far as the bare meaning of the words is concerned. (p. 182)

• B3. For that reason it appears that nothing physical which sense-experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called in question (much less condemned) upon the testimony of biblical passages which may have some different meaning beneath their words. (p. 182f)

• B4. ...having arrived at any certainties in physics, we ought to utilize these as the most appropriate aids in the true exposition of the Bible and in the investigation of those meanings which are necessarily contained therein, for these must be concordant with demonstrated truths. (p. 183)

• The first two quotations express the same 'accommodation' understanding of biblical language as Calvin adopted. The third recognises that, as a result of this, the literal sense of the biblical text may sometimes be at variance with the scientific understanding of the natural phenomenon described. In the final quotation Galileo makes the point made by Prof. McKay that one reason why biblical interpreters should take scientific knowledge into account is that it will help them to recognise when the biblical writers are using the language of appearance or cultural idioms, and so help them avoid the kind of misinterpretation made by those who condemned Galileo.
