Your brain is far too complex and mercurial for its behavior to be predicted in any but the broadest outlines or for any but the shortest distances in the future. Faced with the extraordinary dynamical features of a functioning brain, no device constructible in this universe could ever predict your behavior, or your thoughts, with anything more than merely statistical success. ¶ So one need not fear being reduced to a clanking robot or an empty machine. Quite to the contrary, we are now in a position to explain how our vivid sensory experience arises in the sensory cortex of our brains: how the smell of baking bread, the sound of an oboe, the taste of a peach, and the color of a sunrise are embodied in a vast chorus of neural activity. We now have the resources to explain how the motor cortex, the cerebellum, and the spinal cord conduct an orchestra of muscles to perform the cheetah’s dash, the falcon’s strike, or the ballerina’s dying swan. … On this matter of conceptual development there is especial cause for wonder. For the human brain, with a volume of roughly a quart, encompasses a space of conceptual and cognitive possibilities that is larger, by one measure at least, than the entire astronomical universe. It has this striking feature because it exploits the combinatorics of its 100 billion neurons and their 100 trillion synaptic connections with each other.
The supposedly immaterial soul, we now know, can be bisected with a knife, altered by chemicals, started or stopped by electricity, and extinguished by a sharp blow or by insufficent oxygen.
The religious hypothesis of mind-body dualism has been in trouble with evolutionary biology, and with several other sciences as well, for more than a century. It didn’t need any special input from artificial intelligence or neuroscience to make it scientifically implausible. I bring it up here only because it is a clear example of a popular and important belief currently under siege by modern information. And because its example may be repeated. The fact is, there is a much more intriguing area of current conceptual commitment, one more likely to be affected by emerging cognitive theory in particular. It lies even closer to home and is even more widespread, if that is possible, than mind-body dualism. It is our current self-conception: our shared portrait of ourselves as self-conscious creatures with beliefs, desires, emotions, and the power of reason.
The last thirty years have witnessed a major revival in the philosophical, theological, scientific, and popular literature of the traditional design argument for theism. Probably the most convincing and widely discussed of these arguments is based on the so-called “fine-tuning” of the cosmos, which refers the fact that the parameters of physics and the initial conditions of the universe are balanced on a razor’s edge for life to occur. For example, calculations by Brandon Carter indicate that if the force of gravity had been stronger or weaker by one part in 1040, then life-sustaining stars could not exist (Davies, 1984, p. 242); similarly, calculations indicate that if the strong nuclear force, the force that binds protons and neutrons together in an atom, had been stronger or weaker by as little as 5%, life would be impossible. ( Barrow and Tipler, p. 322.) As the eminent Princeton physicist Freeman Dyson notes, “There are many . . . lucky accidents in physics. Without such accidents, water could not exist as liquid, chains of carbon atoms could not form complex organic molecules, and hydrogen atoms could not form breakable bridges between molecules” (1979, p. 251) — in short, life as we know it would be impossible.
…the Central Idea of the consilience worldview is that all tangible phenomena, from the birth of the stars to the workings of social institutions, are based on material processes that are ultimately reducible, however long and torturous the sequences, to the laws of physics.
Eminent Cornell astronomer and bestselling author Sagan debunks the paranormal and the unexplained in a study that will reassure hardcore skeptics but may leave others unsatisfied. To him, purported UFO encounters and alien abductions are products of gullibility, hallucination, misidentification, hoax and therapists’ pressure; some alleged encounters, he suggests, may screen memories of sexual abuse. He labels as hoaxes the crop circles, complex pictograms that appear in southern England’s wheat and barley fields, and he dismisses as a natural formation the Sphinx-like humanoid face incised on a mesa on Mars, first photographed by a Viking orbiter spacecraft in 1976 and considered by some scientists to be the engineered artifact of an alien civilization. In a passionate plea for scientific literacy, Sagan deftly debunks the myth of Atlantis, Filipino psychic surgeons and mediums such as J.Z. Knight, who claims to be in touch with a 35,000-year-old entity called Ramtha. He also brands as superstition ghosts, angels, fairies, demons, astrology, Bigfoot, the Loch Ness monster and religious apparitions. ~ Publishers Weekly
I have no bone to pick with legitimate science. Indeed, it has been argued repeatedly that science was born in Christian Europe precisely because Christian theology helped provide worldview justification for its assumptions. What I do reject is the idea that science and science alone can claim to give us knowledge. This assertion — known as scientism — is patently false and, in fact, not even a claim of science, but rather, a philosophical view about science. Nevertheless, once this view of knowledge was widely embraced in the culture, the immediate effect was to marginalize and privatize religion by relegating it to the back of the intellectual bus. To verify this, one need only compare the number of times scientists, as opposed to pastors or theologians, are called upon as experts on the evening news.
[P]eople no longer base their decisions on a careful use of abstract reasoning in assessing the pertinent issues, nor are they as capable of doing so compared to earlier generations when thought was communicated by writing and abstract ideas, not by images… In a sensate culture people believe only in the reality of the physical universe capable of being experienced with the five senses. A sensate culture is secular, this-worldly, and empirical. By contrast, an ideational culture embraces the sensory world but also accepts the notion that an extra-empirical, immaterial reality can be know as well — a reality consisting in God, the soul, immaterial beings, values, purposes, and various abstract object like numbers and propositions… [A] sensate culture will eventually disintegrate because it lacks the intellectual resources necessary to sustain a public and private life conductive of corporate and individual human flourishing.
What should we make of Naturalist’s efforts to explain language and mental states in acceptably naturalistic ways? What does it mean to say that intentionality and conceptual content are perfectly natural? What is there to commend Naturalism to us in it own right? Alston begins by attempting to clarify just what it would mean for a given phenomenon to be described in strictly naturalistic terms, concluding that establishing such criteria is itself difficult. The problem in part is a tendency to allow naturalism to permit any phenomena whatsoever within its ken, a license that Alston characterizes as a kind of "blank check". Unable to find the necessary criteria, Alston settles on: nature is, "by definition, to include all and only what is discoverable by the ‘scientific method’, including the incipient beginnings of this in ordinary sensory observation, and reasoning from the results of observation." Given such a definition, Alston proceeds to ask the epistemological question of why we should think that science is the only purveyor of knowledge. ~ Nate
Our willingness to accept scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural. We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counterintuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is absolute, for we cannot allow a Divine Foot in the door.
In speaking of the fear of religion, I don’t mean to refer to the entirely reasonable hostility toward certain established religions and religious institutions, in virtue of their objectionable moral doctrines, social policies, and political influence. Nor am I referring to the association of many religious beliefs with superstition and the acceptance of evident empirical falsehood. I am talking about something much deeper — namely, the fear of religion itself. I speak from experience, being strongly subject to this fear myself: I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn’t just that I don’t believe in God and, naturally, hope that I’m right in my belief. It’s that I hope there is no God! I don’t want there to be a God; I don’t want the universe to be like that… My guess is that this cosmic authority problem is not a rare condition and that it is responsible for much of the scientism and reductionism of our time. One of the tendencies it supports is the ludicrous overuse of evolutionary biology to explain everything about life, including everything about the human mind.
My guess is that this cosmic authority problem is not a rare condition and that it is responsible for much of the scientism and reductionism of our time. One of the tendencies it supports is the ludicrous overuse of evolutionary biology to explain everything about life, including everything about the human mind. Darwin enable modern secular culture to heave a great collective sigh of relief, by apparently providing a way to eliminate purpose, meaning, and desiring as fundamental features of the world. Instead they become epiphenomena, generated incidentally by a process that can be entirely explained by the operation of the nonteleogical laws of physics on the material of which we and our environments are all composed. There might still be thought to be a religious threat in the existence of the laws of physics themselves, and indeed the existence of anything at all, but it seems to be less alarming to most atheists.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. ¶ Our posturings, our imagined self-importance, the delusion that we have some privilege position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. ¶ The earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. ¶ It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.
What is the nature of the human person? A mere conglomeration of matter that consists of different levels of brain state or a being that is also endowed with a soul? In this final part of the series on Naturalism, Dr. J. P. Moreland exposes the philosophical inadequacies of physicalism and explains why the Christian message is more convincing.
Denying the existence and emergence of morality and ethics, Naturalism, a growing worldview, proves inadequate in explaining human nature and its qualities. Having examined the myth of evolution and scientism in Part 1, Moreland explores the jeopardy of the absence of ethics in this second part of a four-part series.
Scientific Naturalism is a worldview that is powerfully influencing our culture today. So much so that even believers in one and the same God struggle with conflicting views. J.P. Moreland begins the first of his four part series with a clear examination of its belief system and the role theistic evolution plays to perpetuate its ends. Here are parts II, III, IV.
Naturalism" seems to me in this and other respects rather like "World Peace." Almost everyone swears allegiance to it, and is willing to march under its banner. But disputes can still break out about what it is appropriate or acceptable to do in the name of that slogan. And like world peace, once you start specifying concretely exactly what it involves and how to achieve it, it becomes increasingly difficult to reach and to sustain a consistent and exclusive "naturalism." There is pressure on the one hand to include more and more within your conception of "nature," so it loses its definiteness and restrictiveness. Or, if the conception is kept fixed and restrictive, there is pressure on the other hand to distort or even deny the very phenomena that a naturalistic study — and especially a naturalistic study of human beings — is supposed to explain.
The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousand of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so… In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.
The Astonishing Hypothesis is that “You,” your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules.
In science itself I certainly want to include the farthest flights of physics and cosmology, as well as experimental psychology, history, and the social sciences. Also, mathematics, insofar at least as it is applied, for it is indispensable to natural science. What then am I excluding as “some prior philosophy,” and why? Descartes’ dualism between mind and body is called metaphysics, but it could as well be reckoned as science, however false. He even had a causal theory of the interaction of mind and body through the pineal gland. If I saw indirect explanatory benefit in positing sensibilia, possibilia, spirits, a Creator, I would joyfully accord them scientific status too, on a par with such avowedly scientific positions as quarks and black holes. What then have I banned under the name of prior philosophy? ¶ Demarcation is not my purpose. My point in the characterization of naturalism … is just that the most we can reasonably seek in support of an inventory and description of reality is testability of it observable consequences in the time-honored hypothetico-deductive way — whereof more anon. Naturalism need not cast aspersion on irresponsible metaphysics, however deserved, much less on soft sciences or on the speculative reaches of the hard ones, except insofar as a firmer basis is claimed for them than the experimental method itself.
At one level, the continuity of philosophy and empirical science is uncontentious. Many philosophical problems arise because of apparent tensions or conflicts within the assumptions which empirical evidence recommends to us. The most obvious examples are issues in the philosophy of science, such as problems about the interpretation of quantum mechanics, or the asymmetry of time, or the logic of natural selection. But other less specialist philosophical questions, like the existence of free will, also arise because of difficulties raised by empirical assumptions (in particular, in this case, by assumptions about the extent to which human beings are subject to the same laws of nature as the rest of the
In his own era, Darwin’s most formidable opponents were fossil experts, not clergymen. Even today, according to the author, the fossil record, far from conclusive, does not support the presumed existence of intermediate links between species. A law teacher at UC-Berkeley, Johnson deems unpersuasive the alleged proofs for Darwin’s assertion that natural selection can produce new species. He also argues that recent molecular studies of DNA fail to confirm the existence of common ancestors for different species. Doubting the smooth line of transitional steps between apes and humans sketched by neo-Darwinists, he cites evidence for “rapid branching,” i.e., mysterious leaps which presumably produced the human mind and spirit from animal materials. This evidence, to Johnson, suggests that “the putative hominid species” may not have contained our ancestors after all. This cogent, succinct inquiry cuts like a knife through neo-Darwinist assumptions. ~ Publishers Weekly
God does not exist if Big Bang cosmology, or some relevantly similar theory, is true. If this cosmology is true, our universe exists without cause and without explanation. There are numerous possible universes, and there is possibly no universe at all, and there is no reason why this one is actual rather than some other one or none at all. Now the theistically alleged human need for a reason for existence, and other alleged needs, are unsatisfied. But I suggest that humans do or can possess a deeper level of experience than such anthropocentric despairs. We can forget about ourselves for a moment and open ourselves up to the startling impingement of reality itself. We can let ourselves become profoundly astonished by the fact that this universe exists at all.
We must therefore ask ourselves: What sort of thing is it reasonable to believe without proof? I should reply: The facts of sense experience and the principles of mathematics and logic — including the inductive logic employed in science.”
