philosophy of science
Shoulders of Giants? -Philosophy and Science in Context, or, “Lawrence Krauss jumps off!”
If I have seen further [than other scientists/philosophers] it is by standing on ye sholders of Giants.- Isaac Newton
We act as if they’re [philosophers without current knowledge of science] authorities about something; they knew nothing!- Lawrence Krauss
Lawrence Krauss recently appeared on the English [UK] radio show “Unbelievable?” In this radio program, Krauss and Randy Holder, a Christian, were in dialog about “A Universe from Nothing?” [not necessarily Krauss’ book, but the subject in general]. The dialog, unfortunately, showed that Krauss continues in his ignorance of the importance of philosophy to his own subject, as well as his own flippant dismissal of generations of scientists.
At one point in the program (around the 26:00 mark), Krauss says the following:
I don’t [indiscernible–he may say “also”] care about what Mr. Leibniz said… we refer to philosophers who wrote at a time when we didn’t know that there were a hundred billion galaxies. [So?] Who cares what they say? We act as if they’re authorities about something; they knew nothing!- Lawrence Krauss
Really?
I can’t think of a more galling statement for a contemporary cosmologist to make. Gottfried Wilhelm Leibniz, for those who don’t know, happened to be one of the men who discovered infinitesimal calculus. He also (among countless other contributions to mathematics, science, social sciences, engineering, and philosophy) developed a calculator, contributed to the development of binary language, was one of the first to posit that space was relative, and developed the principle of sufficient reason (which supports all scientific investigation).
Yet, according to Krauss, because he lived in a time before we know how large the universe was, he “knew nothing!” You see, Krauss, and some other scientists and thinkers with a scientistic/physicalist bent, too often throw out the very basis of their thought. How far do you think Krauss could get in his cosmological research without infinitesimal calculus? How would Krauss go about investigating the causes of various natural phenomena without the principle of sufficient reason?
The answer is pretty simple: he wouldn’t get anywhere.
Krauss, like those before him, stands on the shoulders of giants. But, unlike those who are humble enough (or who know enough about philosophy and history?) to admit it, Krauss says “We act as if they are authorities about something, they knew nothing!”
Really, Krauss? Let’s see how well your next research project goes if you throw out all the contributions they made to your methodology. Next time you do an experiment, try to do it without parsimony or inference to the best explanation. Write to me how that goes!
What’s happened with people like Krauss, and I can think of others (like Stephen Hawking, Richard Dawkins) who do the same thing, is that in their gusto for the marvels of modern science, they have forgotten the very basis for their methods, their research, and their rationality.
Without philosophy, there would be no way to infer causes from effects; without the principle of sufficient reason, there would be no reason to think that causes even have effects; without a well developed notion that what will happen can be inferred from what has happened, these scientists could not even get going. But then they have the absurd tendency to turn around and reject philosophy. They say things like the quote Krauss fired off above.
Here’s the thing: science is utterly dependent upon philosophy to survive. If we didn’t have philosophy–if we didn’t have the developed notions of rationality, inference, and the like–there would be no science. Other theists (and philosophers) have contributed things like parsimony/Occam’s Razor to the wealth of philosophical methodological backbone which makes the scientific enterprise possible. In fact, there is still debate over whether we can reliably make inferences from science (for one example philosophically defending scientific inference, see Wesley Salmon, The Foundations of Scientific Inference). Some scientists have now apparently become those who sit in the ivory towers, blissfully ignorant of how their own research depends upon others’ outside of their field.
I suspect a multifaceted problem behind the motivation of those who throw philosophy out the window once they’ve embraced full-fledged empiricism. First, many of these thinkers have demonstrated they don’t actually know what empiricism means as a–that’s right–philosophical system. Apart from Krauss and Hawking, one could cite the recent example of Richard Dawkins admitting that he doesn’t know what “epistemic” means. Note to those who embrace that philosophical system of Krauss et al.: without epistemology, you would not even be able to justify inferences to best explanation. How’s that for a dose of reality?
Second, there is a kind of blatant ignorance of–or even intentional trampling on–the historical development of scientific inquiry. I hesitate to say that philosophy makes a “contribution” to science, because that’s not what it is. A simple study of schools of knowledge reveals that science, by its very nature, is utterly dependent upon epistemological research. Without such development, there would be no scientific method.
Third, these scientists constantly make philosophical claims, apparently in complete ignorance of the fact that they are philosophical claims. For example, in the same dialog Krauss argues that “the universe certainly doesn’t care what I like…” and throughout the discussion points out that it doesn’t matter what we think, the universe is revealed in a certain way by research.
He apparently seems utterly oblivious to the fact that that, in itself, is a philosophical position. One could take a rival position and argue that the appearances of nature don’t actually determine reality because everything is mind-dependent (idealism, solipsism, or other schools). It’s not enough to just point at nature and say “see, this is how things are!” because if that’s all one does, then someone could say “Your ideas about how things are are dependent upon your mind and ideas, and therefore don’t have any access to reality.” No scientific research could rebut such an argument, only a philosophical position in which nature can give us a reliable record for rationality can ground science.
Krauss dismisses philosophy very nonchalantly. It seems as though he (and others like him) is oblivious to the fact his entire system is philosophical. Consider the claim that “science can examine reality.” How does one go about proving it? One could argue that one could simply make a test and show that over and over again in circumstances y, x result happens, so we are justified that when we assert that if y, then x. But of course we would have to justify that a test can be connected to reality; we’d have to figure out what it means to have “justified” belief; we have to show that our scientific method is trustworthy; we have to assume that mathematical truths are true; we have to operate within a rational perspective; etc. All of these are philosophical positions. Some of them are debates within philosophy of science, in fact. The bottom line is that whenever someone does science, they are utterly reliant upon philosophy. By simply taking the empirical world as something which can be explored, they have made a number of philosophical assumptions, whether realized or not. Scientists take much of the philosophical development as a given before they even start their research. And then, some of them, like Krauss, have the gall to turn around and dismiss philosophers as though they “know nothing.” Suddenly, he has undermined his own system of thought, without even acknowledging that it is a system of thought.
Frankly, some of these scientists are just confused. Thankfully, many scientists operate with a system that respects the contributions of philosophy to science and encourage the interplay between the fields of knowledge.
Here’s the bottom line for those scientists who agree with Krauss: your entire field of research can only proceed if you grant over a thousand years of philosophical development. One major contribution was made by Leibniz, whom people like Krauss casually dismiss. But without the theistic philosopher with the awesome wig, scientists would have nothing. Thanks, philosophy! Thanks again, Christianity!

Book Review: “Where the Conflict Really Lies” by Alvin Plantinga
There are few names bigger than Alvin Plantinga when it comes to philosophy of religion and there are few topics more hotly debated than science and religion. Plantinga’s latest book, Where the Conflict Really Lies
Plantinga minces no words. The very first line of the book outlines his central claim: “there is superficial conflict but deep concord between science and theistic religion, and superficial concord and deep conflict between science and naturalism.”1
The first part of the book is dedicated to the superficial conflict between science and religious belief. The reason this alleged conflict is important is due, largely, to the success of the scientific enterprise. Because science has shown itself to be a reliable way to come to know the world, if religion is in direct conflict with science, then it would seem to discredit religion. Not only that, but, Plantinga argues, Christians should have a “particularly high regard” for science due to the foundations of the scientific enterprise on a study of the world.2
In order to examine this alleged conflict, Plantinga first takes on the article of science most often taken to discredit religion: evolution. Here, readers may be surprised to find that Plantinga does not try to argue against evolution itself. Rather, Plantinga draws a distinction between the notion of evolution and Darwinism. The former, argues Plantinga, is consistent with Christian belief, whether or not it is the way the variety of life came to be, while the latter is not consistent with Christianity because central to its account is the notion that the process of evolution is unguided.3
WCRL then turns to Richard Dawkins. Plantinga argues that “A Darwinist will think there is a complete Darwinian history for every contemporary species, and indeed for every contemporary organism.”4 Here again there is nothing which puts such a theory in conflict with Christian belief. Writes Plantinga, “[The process of evolution] could have been superintended and orchestrated by God.”5 But Dawkins (and others) claim that evolution “reveals a universe without design.” But what argument is provided towards this conclusion? Plantinga draws out Dawkins reasoning and shows that the only logic given is that evolution could have happened by way of unguided evolution. But then:
What [Dawkins] actually argues… is that there is a Darwinian series of contemporary life forms… but [this series] wouldn’t show, of course, that the living world, let alone the entire universe, is without design. At best it would show, given a couple of assumptions, that it is not astronomically improbable that the living world was produced by unguided evolution and hence without design. But the argument form ‘p is not astronomically improbable’ therefore ‘p’ is a bit unprepossessing… What [Dawkins] shows, at best, is that it’s epistemically possible that it’s biologically possible that life came to be without design. But that’s a little short of what he claims to show.6
Plantinga then moves on to argue that Daniel Dennett’s argument is similarly flawed.7 Paul Draper’s argument that evolution is more likely on naturalism than theism is more interesting, but assumes that “everything else is equal.”8 But then, everything is not equal. Theism provides a number of relevant probabilities which weigh the argument in favor of theism instead.9
The arguments against theism from evolution are therefore largely dispensed. What of the possibility of divine action? Some argue that God doesn’t actually act in the world—in fact, the argument is made that even most theologians don’t believe this, despite writing that God does act in various ways. The argument is made that because of natural laws, God cannot or does not intervene.10 However, one can simply argue that the correct view of a natural law is that “When the universe is causally closed (when God is not acting specially in the world), P.”11
Plantinga does acknowledge that there are some fields in science which do provide at least superficial conflict with theism. These include evolutionary psychology and (some) historical critical scholarship.12 Evolutionary psychology generally doesn’t challenge religious belief. “Describing the origin of religious belief and the cognitive mechanisms involved does nothing… to impugn its truth.”13 Now some suggest that religious beliefs are due to devices not aimed at truth, and this would provide a reason to doubt religious belief.14 However, the way that most do this is by conjoining atheism with psychology or operating under other assumptions which undermine religious belief a priori. While this may mean that specific conclusions in psychology are in conflict with theism, these conclusions only follow from the anti-theistic assumptions at the bottom. Thus, while some accounts of evolutionary psychology are in conflict with theism, they don’t provide a solid basis for rejecting it.15 Similarly, varied methods of historical concept may draw some conclusions which are in conflict with Christian theism, but these methods are themselves undergirded by assumptions that theism is, at best, not to be entered into historical discussion.16
There are, Plantinga argues, significant reasons to think that theism is in concord with science. First, the argument from cosmological fine-tuning, he argues, gives “some slight support” for theism.17 The section on fine-tuning has responses to some serious criticisms of such arguments. Most interesting are his responses to Tim and Lydia McGrew and Eric Vestrup—in which Plantinga argues that we can indeed get to the point where we can assess the fine-tuning argument;18 Plantinga’s discussion of the multiverse;19 and his discussion of relevant probabilities regarding fine-tuning.20
Michael Behe’s design theory is discussed at length in WCRL.21 Plantinga offers some additional insights into the Intelligent Design debate. He argues that one can view design not so much as a probabilistic argument but instead as simple perception.22 He reads both Behe and William Paley in this light and argues that they are offering design discourses as opposed to arguments.23 This, in turn, allows him to argue that design is a kind of “properly basic belief” and he offers a robust discussion of epistemology to support this intuition.24
Further, there is deep concord between Christian Theism and Science when one looks at the very roots of the scientific endeavor. Here, rather than simply listing various theists who helped build the empirical method, Plantinga argues that science relies upon various theistic assumptions in order for its methods to succeed. These include the “divine image” in which humans are capable of rational thought;25 God’s order as providing regularity for the universe;26 natural laws;27 mathematics;28 induction;29 and simplicity and “other theoretical virtues” (like beauty).30
Finally, Plantinga turns to naturalism: does it really resonate so well with science? Plantinga grants for the sake of argument that there is at least superficial concord between naturalism on science, if only because so many naturalists trumpet this “fact.”31 Yet there is, he argues, a deep conflict between science and naturalism: namely, that if evolution is true and naturalism is true, there is no reason to trust our cognitive abilities.32 “Suppose you are a naturalist,” he writes, “you think there is no such person as God, and that we and our cognitive faculties have been cobbled together by natural selection. Can you then sensibly think that our cognitive faculties are for the most part reliable?”33
Plantinga argues you cannot. The reason is because we have no way to suppose that evolution is truth aimed, but rather it is merely survival aimed (if indeed it is aimed at all!). He also argues that because naturalists are almost all materialists, there is no way to adequately ground beliefs.34 Finally, because naturalism and evolution conjoin to give a low probability that our rational abilities are reliable, we have received a defeater for every belief we have, including naturalism and evolution.35 Thus, the conflict “is not between science and theistic religion: it is between science and naturalism. That’s where the conflict really lies.”36
WCRL covers an extremely broad range of topics, and will likely be critiqued on each topic outlined above and more. The book touches on issues that are at the core of the debate between naturalists and theists, and as such it will be highly contentious. That said, the book is basically required reading for anyone interested in this discourse. Plantinga provides extremely valuable insights into every topic he touches. His discussion of biological design, for example, provides unique insight into the topic by locating it within epistemology as opposed to biology alone. Further, his “evolutionary argument against naturalism” continues to live despite endless criticism. The list of important topics Plantinga illumines in WCRL is extensive.
