The first of Alister McGrath’s three earned Oxford University doctorates was in molecular biophysics.  The next two were in, first, theology and, second, intellectual history.  On pages 38-39 of Alister E. McGrath, Darwinism and the Divine: Evolutionary Thought and Natural Theology (Chichester: Wiley-Blackwell, 2011), McGrath offers an excellent example of how the same bare scientific facts can be interpreted and expanded upon in radically different ways, depending upon the presuppositions that interpreters bring to them:

 

As his initial illustration, he uses a passage from the Oxford evolutionary biologist, science popularizer, and vocal “New Atheist” polemicist Richard Dawkins, cited from

 

Dawkins’s early masterpiece of Darwinian popularization, The Selfish Gene (1976).  This important and influential work supplements overt scientific description with a covert metaphysic, which represents genes as active agents in control of their own destiny and those of their hosts.

[Genes] swarm in huge colonies, safe inside gigantic lumbering robots, sealed off from the outside world, communicating with it by tortuous indirect routes, manipulating it by remote control.  They are in you and me; they created us, body and mind, and their preservation is the ultimate rationale for our existence.

This passage presents a completely defensible scientific statement — “genes are in you and me” — with a series of rather less defensible metaphysical assertions.  We are told, for example, that the preservation of our genes “is the ultimate rationale for our existence.”  This is, however, simply a presentation of a “gene’s eye view” — a hypothetical metaphysical way of interpreting scientific observation, which arguably reached its zenith in the early 1980s.  This approach conceived the gene as an active controlling agent, which could be regarded as “manipulating” the destiny of biological entities, including humanity.  Yet the empirically verified facts in this statement are limited to the brief statement that genes “are in you and me.”  The rest is speculative.  Metaphysical presuppositions have been smuggled in, and portrayed as if they were scientifically verified facts.

 

McGrath then cites a satirically rewritten version of the same paragraph created by the Oxford University systems biologist Denis Noble:

 

Noble retains what is scientifically valid and verifiable in Dawkins’s prose.  Then, in a masterly piece of ideological subversion, he identifies and inverts Dawkins’s non-scientific statements.  Noble playfully portrays genes as passive, where Dawkins depicts them as active:

[Genes] are trapped in huge colonies, locked inside highly intelligent beings, moulded by the outside world, communicating with it by complex processes, through which, blindly, as if by magic, function emerges.  They are in you and me; we are the system that allows their code to be read; and their preservation is totally dependent on the joy that we experience in reproducing ourselves.  We are the ultimate rationale for their existence.

 

Obviously, Dawkins and Noble depict the functional status of genes in radically distinct ways.  They accurately report the same very limited scientific information, but then they go completely different directions with their metaphysical interpretations — which each of them suggests (one in earnest and the other more or less in jest) to be just as secure, scientifically speaking, as the fact that genes “are in you and me.”  Their statements are empirically equivalent, in a sense, but both cannot be correct.

 

Alister McGrath’s comment on the foregoing two  summary statements is important:

 

So which is right?  How could we decide which is to be preferred on scientific grounds?  As Noble observes, “no-one seems to be able to think of an experiment that would detect an empirical difference between them.”  The question of the metaphysical presuppositions and consequences of evolutionary thought is entirely legitimate, and is of considerable interest.  Nevertheless, it is important to be clear that discussion of this issue is often muddied by confusion over the status of the metaphysical dimensions of evolutionary thought.  The challenge facing anyone interested in reflecting on the cultural, religious, ethical, and theological implications of biological evolution is to separate the observational evidence from the accumulated detritus of metaphysical speculation.

Finally, here’s one that, I think, might be especially interesting for Latter-day Saints who are inclined to theological speculation.  It’s reprinted from the 21 April 2019 issue of Scientific American:
