David Hirschman at Big Think summarizes recent views on the nature of consciousness:
Dr. Antonio Damasio, a neuroscientist from the University of Southern California who has studied the neurological basis of consciousness for years, tells Big Think that being conscious is a “special quality of mind” that permits us to know both that we exist and that the things around us exist. He differentiates this from the way the mind is able to portray reality to itself merely by encoding sensory information. Rather, consciousness implies subjectivity—a sense of having a self that observes one’s own organism as separate from the world around that organism.
“Many species, many creatures on earth that are very likely to have a mind, but are very unlikely to have a consciousness in the sense that you and I have,” says Damasio. “That is a self that is very robust, that has many, many levels of organization, from simple to complex, and that functions as a sort of witness to what is going on in our organisms. That kind of process is very interesting because I believe that it is made out of the same cloth of mind, but it is an add-on, it was something that was specialized to create what we call the self.”
It seems to me there is something missing from this all-too-brief summary of Damasio’s account. To have a self (and thus to be robustly conscious) is not just to be a “witness to what is going on in our organism” or to recognize that one’s own organism is separate from the world.
To be conscious is to have the felt sense that something matters—has significance or import. A sophisticated computer might know that it exists, that things around it exist, and that there is a difference between it and the world. But I doubt that such a machine would have a felt concern for something because it is not a biological organism with needs embedded in feeling states. Self-awareness is not merely a “witness” but an active sorter of what to attend to and what to ignore in light of what matters. It is hard to imagine a consciousness without this sorting ability.

Do We Think What Our Language Tells Us to Think? August 29, 2010

1 comment so far
What if our entire capacity for thinking is limited and determined by our respective languages, forever preventing true cross-cultural understanding from taking place? An interesting article by linguist Guy Deutscher in the New York Times Magazine gives a good overview of the linguistic debate while introducing his new book, Through the Language Glass: Why the World Looks Different in Other Languages.” In brief: in 1940 anthropologist Benjamin Lee Whorf suggested that language molds your capacity for thinking, to the point that if the language does not contain a certain concept, you’re incapable of thinking about it or understanding it.
In particular, Whorf announced, Native American languages impose on their speakers a picture of reality that is totally different from ours, so their speakers would simply not be able to understand some of our most basic concepts, like the flow of time or the distinction between objects (like “stone”) and actions (like “fall”). For decades, Whorf’s theory dazzled both academics and the general public alike. In his shadow, others made a whole range of imaginative claims about the supposed power of language, from the assertion that Native American languages instill in their speakers an intuitive understanding of Einstein’s concept of time as a fourth dimension to the theory that the nature of the Jewish religion was determined by the tense system of ancient Hebrew.
Deutscher tells us that the theory has been abandoned and ridiculed by linguists for decades, but for one thing, linguists aren’t the only ones who have an interest in the epistemological side of language—20th century philosophers have had many a discussion on the subject; and for another, I’ve certainly heard scholars from many different fields refer to such ideas as established truths. But, says Deutscher, Whorf’s theory lost out because of it radical approach:
Whorf, we now know, made many mistakes. The most serious one was to assume that our mother tongue constrains our minds and prevents us from being able to think certain thoughts. The general structure of his arguments was to claim that if a language has no word for a certain concept, then its speakers would not be able to understand this concept. If a language has no future tense, for instance, its speakers would simply not be able to grasp our notion of future time. It seems barely comprehensible that this line of argument could ever have achieved such success, given that so much contrary evidence confronts you wherever you look. When you ask, in perfectly normal English, and in the present tense, “Are you coming tomorrow?” do you feel your grip on the notion of futurity slipping away? Do English speakers who have never heard the German word Schadenfreude find it difficult to understand the concept of relishing someone else’s misfortune? Or think about it this way: If the inventory of ready-made words in your language determined which concepts you were able to understand, how would you ever learn anything new?
Says Deutscher, the interesting thing isn’t that language limits your thinking, but enforces a certain kind of thinking:
Some 50 years ago, the renowned linguist Roman Jakobson pointed out a crucial fact about differences between languages in a pithy maxim: “Languages differ essentially in what they must convey and not in what they may convey.” This maxim offers us the key to unlocking the real force of the mother tongue: if different languages influence our minds in different ways, this is not because of what our language allows us to think but rather because of what it habitually obliges us to think about.
In German, Spanish, Russian and many other languages, you have to think about nouns in terms of masculine and feminine. In English we have to think about actions in a certain tense—have we done something, will we do something, or are we doing it? In Chinese apparently you don’t have to be that specific. In Western languages we tend to put ourselves in the middle of most of our spatial references (left, right, back, forth), but some tribal languages do not: their talk about space involve cardinal points (north, south, east and west), not relative references to ourselves. If our language has certain words for colors, we are more apt to perceive them. The bottom line is that language does affect our way of thinking, in terms of what we have to be aware of, and what we learn to pay attention to, and to disregard. But to what extent?
For many years, our mother tongue was claimed to be a “prison house” that constrained our capacity to reason. Once it turned out that there was no evidence for such claims, this was taken as proof that people of all cultures think in fundamentally the same way. But surely it is a mistake to overestimate the importance of abstract reasoning in our lives. After all, how many daily decisions do we make on the basis of deductive logic compared with those guided by gut feeling, intuition, emotions, impulse or practical skills? The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies. We may not know as yet how to measure these consequences directly or how to assess their contribution to cultural or political misunderstandings. But as a first step toward understanding one another, we can do better than pretending we all think the same.
Whether Deutscher’s reevaluation of Whorf’s theory is really something new in linguistics I can’t say—I’m not a linguist—but philosophically this is hardly a new approach; on the contrary, it is reminiscent of what some Continental philosophers of the twentieth century said a while back (actually, it was that brilliant linguist Nietzsche who first floated a similar idea!): we don’t all think the same way, because our available language creates a perspective or horizon, for all that we take for granted and are likely to notice—a hermeneutic circle. Not Whorf’s thought prison, but a Lifeworld of our interpretations into which we are thrown, and which takes some intellectual effort to rise above—hard, but not impossible. You can find similar ideas in the writings of several contemporary German and French scholars, and some of them have actually been influenced by Jakobson.
So without having read Deutscher’s book yet, it seems to me that the idea of language as a primary condition for understanding the world, but not per se a prison of interpretation, is not exactly new in the general realm of scholarship. And philosophically as well as scientifically, it is already the subject of a revisionist overhaul, focusing on our neurological/ontological similarities beneath the cultural differences!
But I’m glad Deutscher brought up the name and influence of Roman Jakobson. I myself actually had the privilege of meeting him at the 500th anniversary of the University of Copenhagen in 1979. Jakobson was talking about his amazing life in a succession of countries, and to the best of my recollection he said, “The surest way to stay mentally active is to change country and language every 10 years!” And he wasn’t talking about just learning new words and rules of grammar…
The Press Should Stop Making Philosophical Claims August 25, 2010

add a comment
In the Times Literary Supplement, Jerome Burne reviews Irving Kirsch’s book The Emperor’s New Drugs, in which Kirsch argues that anti-depressant drugs—SSRIs like Prozac, Seroxat and Lustral—are no better than placebos. The evidence for his claim is impressive and it does not surprise me that the pharmaceutical industry has made billions of dollars by suppressing evidence.
What is bothersome about Burne’s review is his utterly misleading use of 20th Century philosophy of mind to make his case.
His review is subtitled: “A debate on Cartesian dualism has led to radically differing approaches to the treatment of depression”. The introduction of the article suggests that opposition to Descartes’ claim that the mind (or soul) is a non-physical substance led to the assumption that brain functions are nothing but chemical reactions that can be controlled through drug intervention—an approach that is now proving to be ineffective.
Sixty years ago, the philosopher Gilbert Ryle published his famous attack on Cartesian dualism, The Concept of Mind, which claimed to find a logical flaw in the popular notion that mental life has a parallel but separate existence from the physical body. Among other effects it provided sophisticated support for the psychological behaviourists, then in the ascendant, who asserted that since we could not objectively observe mental activity it was not really a fit subject for scientific investigation.
Nowhere was the notion of banning mental states taken up more enthusiastically than by the emerging discipline of neuropsychiatry. If consciousness and all its manifestations were “merely” the firing of neurons and the release of chemicals in the brain, what need was there to focus on mental states? Once the physical brain was right, the rest would follow.
It was an approach that has spawned a vast pharmaceutical industry to treat any pathological psychological state – anxiety, shyness, depression, psychosis – with a variety of pills.
The clear implication of the article is that we should return to a dualistic conception of the mind that treats the mind as independent of physical states.
But this is just silly. Ryle rightly criticized the Cartesian picture of the mind as assuming a “ghost in the machine”—a weird supernatural entity that somehow issues in experience and rationality. Ryle’s criticism of Descartes was surely apt.
However, Ryle’s solution to uncovering the nature of the mind, behaviorism, was rejected by cognitive science decades ago and few researchers think that we can understand the mind by ignoring mental activity. I doubt that behaviorism had much impact on the development of pharmaceutical interventions.
Furthermore, the fact that we haven’t yet discovered the complex brain functions that cause psychosis or depression does not entail that the mind must be non-physical. The failure of drug interventions simply shows that the brain is more complex than many researchers had thought and mental illness is unlikely to be cured by a pill.

Strawson on Free Will vs. Determinism July 27, 2010
Posted by Dwight Furrow in Dwight Furrow's Posts, Philosophy.Tags: free will and determinism
add a comment
Philosopher Galen Strawson has a wonderful article on the topic of free will on the NY Times Blog. The article is accessible and brief. It is worth reading for anyone interested in whether we have free will or not. (The comments for the most part are hopeless)
The short Strawsonian answer is “no” because any choice I make will be based on preferences, values, ideals or some other causal factor that I did not choose.
Some people are troubled by this, thinking that without free will we cannot be responsible for our actions. But Strawson shows why that conclusion does not follow.
He quotes the novelist Ian McEwan.
I can’t do better than the novelist Ian McEwan, who wrote to me: “I see no necessary disjunction between having no free will (those arguments seem watertight) and assuming moral responsibility for myself. The point is ownership. I own my past, my beginnings, my perceptions. And just as I will make myself responsible if my dog or child bites someone, or my car rolls backwards down a hill and causes damage, so I take on full accountability for the little ship of my being, even if I do not have control of its course. It is this sense of being the possessor of a consciousness that makes us feel responsible for it.”
I think Strawson is right. The important question is “Does it Matter?” Would our ethics or politics be better if we gave up the illusion of free will?

Judgment Day July 11, 2010
Posted by Dwight Furrow in Dwight Furrow's Posts, Philosophy, Science.Tags: science-fiction, time travel
2 comments
I don’t find thought experiments about the nature of God very interesting—but throw in time travel and I perk up a bit.
Mike Lebossiere poses the following puzzle:
Sally is working on a time travel project and during one experiment, her own smartphone appears in the lab. Startled, she checks her pocket and finds that her phone is there. Yet it also appears to be on the table. Picking it up, she finds that video has been recorded on it. Much to her horror and dismay, it seems to be a video of her saying that she has killed her husband for having an affair with her friend, only to find out after that she was wrong. In the video, she can she the body of what seems to be her dead husband. The video closes with her future self saying that she is sending back the phone to tell her past self to not kill her husband; future Sally then shoots herself in the head as the phone is being sent into the past.
Being something of a skeptic, Sally checks the phones carefully and finds that (aside from some blood on the future phone that matches her husband’s blood type) the two are identical. This convinces Sally and she does not kill her husband.
Now, let God be brought into the picture, at least hypothetically. If one prefers to leave God out of this game, then an omniscient observer who judges people for their deeds and misdeeds can be used in His place.
In this scenario, what would God actually “see” and how would He judge?
On one hand, the future Sally did kill her husband and send the phone back. After all, without those events, then the phone would not have the video recorded on it and would not have been sent back. As such, God would judge that Sally was guilty of suicide and murder, hence worthy of divine punishment. Also, both Sally and her husband would be dead and thus would have gone off to the relevant afterlife (assuming there is such a thing).
On the other hand, the time traveling phone prevented Sally from killing her husband and committing suicide. Thus, Sally would not be judged for these deeds. Also, neither Sally nor her husband would be dead. In effect, that future event never will be, although it must have been (otherwise there would be no phone).
[…]
One classic view of God and time is that God perceives all of time “at once.’ To use an analogy, God’s perspective is like being able to see the entire filmstrip of a movie at once. The past, present and future are just positions on the strip relative to a specific film cell. Hence, He does not see any changes in the past-He merely sees as the events that did occur, shall occur and are occurring all “at once.” So, God would “see” the phone appear from a future that never was to save Sally from committing a murder that never will be.
I think this just points out that the idea of time travel is logically incoherent. The whole idea of going back in time to “undo” an event that has occurred requires that the event both did happen and did not happen. That is a logical contradiction. The future event would have to have happened in order for it to be caused to not happen. Since the “undoing” event is in a cause effect relation with the undone event which must exist for the undoing event to occur we have backward causation going on.
And it is not obvious that backward causation is a coherent idea. It would seen that the outcome of an event must happen only after the event. Although quantum mechanics seems to allow for backward causation (if I understand it correctly) surely there is no experimental result that depends on that idea.
So what would God see? It is a widely accepted view that God is a rational being and thus can neither see nor coherently think contradictory states of affairs. If time travel is logically impossible then trying to imagine how an omniscient being would view it doesn’t help.
Of course, if Sally is the sort of person who would murder her spouse for infidelity then God may have all the justification God needs.

Artificial Life June 1, 2010
Posted by Dwight Furrow in Philosophy, Science, Technology.Tags: Craig Venter
2 comments
An article in a recent issue of Science reported that Craig Venter (the leader of one team of researchers that successfully mapped the human genome) has made a synthetic cell by inserting a fabricated genome into a bacterium. The press has been reporting this as the first successful attempt to create artificial life. But the paper has created a good deal of controversy, not only regarding the ethical issues, but whether this is really artificial life or not.
Sune Holm has an excellent summary of the debate:
In an interview with the BBC Nobel Prize-winning biologist Paul Nurse points out that not just the genome but the entire cell would have to be synthesized for it to be properly artificial. What Venter has produced is the first living cell which is entirely controlled by synthesized DNA, not artificial life.
George Church, geneticist at Harvard Medical School, doesn’t think that Venter has really created new life either. Commenting in Nature, Church says that the bacterium made by Venter “is not changed from the wild state in any fundamental sense. Printing out a copy of an ancient text isn’t the same as understanding the language.”
Also commenting in Nature, Jim Collins, professor of biomedical engineering at Boston University, points out that “The microorganism reported by the Venter team is synthetic in the sense that its DNA is synthesized, not in that a new life form has been created. Its genome is a stitched-together copy of the DNA of an organism that exists in nature, with a few small tweaks thrown in.
Holm argues that all of these skeptical comments assume a particular conception of what artificial life should be:
These comments seem to me to suggest the following requirement: In order to create an artificial organism one must build it in a way analogous to the way we build other complex artifacts such as watches and washing machines. This involves making the different parts that compose the machine and put them together according to a design plan. Furthermore, it is by being able to create artificial life in this sense that we satisfy the necessary condition for understanding life expressed in Feynman’s dictum, “What I cannot create I do not understand,” so often referred to in synthetic biology. If some day we become able to design and build a living thing from scratch by fabricating all its parts out of nonliving matter and assemble them according to a plan of our own design, then we may be said to understand life.
Holm suggests that some of the ethical worries many people have regarding this technology is the result, not of potential harmful effects, but of our uncertainty about how to classify such “organisms” and our inability to know what is “right or wrong with respect to these entities.”
The products of synthetic biology are typically presented in terms of rather vague but highly connotative hybrid notions such as “living machine” and “synthetic organism.” Dealing with ethical concerns arising from synthetic biology research it is important that we don’t neglect the need to investigate how to conceptualize the products we expect synthetic biology to result in. This task will involve investigation of our notions of organism, machine, artifact, and life. Venter’s achievement has made the need for philosophical exploration of these categories even more pressing.
Holm may be right that “ontological uncertainty” breeds ethical uncertainty. But this is uncertainty we will have to live with. I doubt that any of these new entities will fall neatly into the ontological categories we have available today. The question of whether they are “really artificial” or not may have no answer. And we may have to invent new categories to make sense of scientific innovation.
So it is probably best, at this point, not to get too hung up on definitions, which will likely be quite fluid.

Humanities Under Fire May 24, 2010
Posted by Dwight Furrow in Dwight Furrow's Posts, Education, Philosophy.Tags: business model of education, Stanley Fish, utilitarianism
1 comment so far
The Humanities—literature, the arts, history, and philosophy—are in deep trouble. As budget cuts percolate through our educational system, these disciplines will be the first to be down-sized because they seem to produce little tangible benefit.
And Stephen Mexal takes literature professor Stanley Fish to task for encouraging this trend.
Over the past year or so, Stanley Fish has occasionally devoted his New York Times blog to the notion that, as he put it recently, higher education is “distinguished by the absence” of a relationship between its activities and any “measurable effects in the world.” He has singled out the humanities for lacking what he called “instrumental value,” writing that “the value of the humanities cannot be validated by some measure external” to the peculiar obsessions of scholars. The humanities, Fish claimed, do not have an extrinsic utility—an instrumental value—and therefore cannot increase economic productivity, fashion an informed citizenry, sharpen moral perceptions, or reduce prejudice and discrimination. […]
This sentiment reached its logical apex last year in an article in The New York Times titled, “In Tough Times, the Humanities Must Justify Their Worth.” […]
So when Fish claimed that the benefits of humanities research were limited to the researcher or the classroom, and that the public should therefore not have to “subsidize my moments of aesthetic wonderment,” he was drill-baby-drilling into the zeitgeist quite nicely.
As Mexal points out, the issue is not whether the arts, history, or literature (or philosophy) are useful—they obviously are. The issue is whether academic research into these areas is useful. What is the utility or academic analyses of art, philosophy, literature, or history?
Mexal’s answer is that the value of research in the humanities is neither immediate nor predictable. But he cites a variety of examples in which literary, historical, and philosophical works led directly to new developments in fields such as computer programming, national intelligence, and counter-intelligence.
What unites those stories is not that they exemplify times when humanities research has had instrumental value, but rather times when it has had unintended instrumental value. Those scholars did not intend, nor could they have anticipated, the applied value of their work. Yet that’s not to say the application of their work was the point of their work. After all, scholars weren’t studying Shakespeare with an eye toward establishing the CIA. Instead, research in the humanities, like research in all disciplines, is valuable precisely because we never know where new knowledge will lead us.
Morality Magnets March 30, 2010
Posted by Dwight Furrow in Dwight Furrow's Posts, Ethics, Philosophy, Science.Tags: Joshua Green, moral psychology
add a comment
Research at MIT shows that moral judgments are affected by magnetic stimulation of the brain. Here’s the abstract:
When we judge an action as morally right or wrong, we rely on our capacity to infer the actor’s mental states (e.g., beliefs, intentions). Here, we test the hypothesis that the right temporoparietal junction (RTPJ), an area involved in mental state reasoning, is necessary for making moral judgments. In two experiments, we used transcranial magnetic stimulation (TMS) to disrupt neural activity in the RTPJ transiently before moral judgment (experiment 1, offline stimulation) and during moral judgment (experiment 2, online stimulation). In both experiments, TMS to the RTPJ led participants to rely less on the actor’s mental states. A particularly striking effect occurred for attempted harms (e.g., actors who intended but failed to do harm): Relative to TMS to a control site, TMS to the RTPJ caused participants to judge attempted harms as less morally forbidden and more morally permissible. Thus, interfering with activity in the RTPJ disrupts the capacity to use mental states in moral judgment, especially in the case of attempted harms.
Apparently, the part of the brain involved in understanding the intentions of others, when stimulated by magnetic fields, is suppressed, which understandably alters our moral judgments. The NPR report on this study points out that we judge intentions as well as actions. The magnetic pulse makes normal adults reason like 4 year olds.
Joshua Greene, the Harvard psychologist who has perhaps done the most important empirical work supporting the notion that morality is a function of the brain, thinks this kind of study has important metaphysical implications:
The fact that scientists can adjust morality with a magnet may be disconcerting to people who view morality as a lofty and immutable human trait, says Joshua Greene, psychologist at Harvard University. But that view isn’t accurate, he says. […]
The scientists are trying to take concepts such as morality, which philosophers once attributed to the human soul, and “break it down in mechanical terms.”
If something as complex as morality has a mechanical explanation, Green says, it will be hard to argue that people have, or need, a soul.
I’m not convinced that this study is all that important. It is not surprising that damage to the brain can affect our judgments. Furthermore, the fact that we can identify the part of the brain that accurately grasps the intentions of others tells us little about what we should do with that understanding. But I agree with Greene that the cumulative weight of the many studies showing various aspects of morality to be rooted in the brain suggests (without entailing) that notions such as the “soul” hypothesis do no explanatory work.
And as Jon Mandle at Crooked Timber points out:
Rather, it highlights the importance of attribution of intention in the moral judgment of normal adults, shows how localized in the brain this function is, and demonstrates how easily it can be suppressed in isolation from other functions.
And Sarah-Jayne Blakemore, a brain expert and University College London, pointed out:
“What is interesting is that this is a region that is very late developing – into adolescence and beyond right into the 20s.
“The next step would be to look at how or whether moral development changes through childhood into adulthood.”
Ah…I ‘m sure that it does—see Gilligan, Kohlberg et al.

Know-Nothing Philosophers? March 25, 2010
Posted by Dwight Furrow in Dwight Furrow's Posts, Philosophy, Science.Tags: Jerry Fodor, Michael Ruse, theory of evolution, Thomas Nagel
2 comments
Recently, there have been a number of books written by well-known philosophers—Thomas Nagle and Jerry Fodor in particular—calling into question fundamental features of Darwinian evolutionary theory. Philosopher of Science Michael Ruse has a readable take-down of this trend.
What does one say about these critics? One could certainly pick apart individual things, for instance Fodor’s claims about selective breeding versus natural selection.[…]
But rather than work over the details, I want to draw attention to the way this crop of critics ignores evolutionary biology—aside from the kind of cherry-picking in which Fodor engages. Nagel may sneer about the failure to find “accessible literature” that answers his worries. In what part of the library was he doing his literature search? Where, for example, is any discussion of the Grants’ work on the Galápagos finches? What about a detailed look at the new scholarship that is challenging earlier thinking about the evolution of bipedalism? What about the discoveries of molecular biology and of the similarities (homologies) between humans and fruit flies? And why no mention of Marc Hauser and his work uncovering the secrets of moral thinking? There is a deafening silence on those and other issues. Fodor, Nagel, and Plantinga don’t need to turn themselves into biochemists, but some awareness of the issues and advances would not be entirely misplaced.
Ruse points to a problem that I thought was an artifact of a bygone era. Earlier generations of philosophers often theorized about science without having much knowledge of science. But I thought contemporary philosophers had largely given up that approach and today endeavor to learn the science before pontificating about it.
So why are these respected philosophers returning to the bad old days? Ruse speculates:
This total lack of interest in the science is surely suggestive. The critics are being driven by other, for them deeper, concerns. And as an evolutionist, I turn to the past for clues. What fueled the initial opposition to Darwin was a concern with our species, with Homo sapiens. For 150 years, since the Origin, critics have feared that we humans might become part of the evolutionary picture—not just our bodies, but our minds, our very souls. What makes us distinctively and uniquely human? This worry is still alive and well in today’s philosophical community. Plantinga is open in his fear that Darwinism makes impossible the guaranteed existence of our species. More, for years he has argued that Darwinism is bound up with the metaphysical belief that everything is natural (as opposed to supernatural), and that this leads to a collapse of rational belief and knowledge. The chance elements in Darwinism are simply not compatible with Plantinga’s Christian faith.
As nonbelievers, Nagel and Fodor are a bit different, but not that different. For years Nagel has argued against a reductive view of the human mind, believing it to be more than just molecules in motion—the obvious end result of Darwinism. At some level, Nagel believes, the mind is above the material. It is perhaps a stretch, but probably not too much of a stretch, to say that the kind of sympathetic attitude that Nagel takes toward intelligent design points not so much to a concealed theism (akin to Plantinga’s open theism) as to a kind of vitalism, in which there are nonnatural, nonphysical forces that direct things in the material world.
And then there is Fodor. The final section of his new book is very revealing. As a dreadful warning to those who do not accept his main conclusions, Fodor prints passage after passage of claims by Darwinians that one can understand human nature and thinking as the product of natural selection: This is where we will all end up if we don’t stop the rot right now. My suspicion is that Fodor doesn’t really give a damn about fruit flies or finches or anything else out there. But when it comes to Homo sapiens, he wants no part of a naturalistic explanation that reduces design to the workings of blind law. There may not be a God, but we sure are made in his image.
This strikes me as a plausible explanation. There is, even among some philosophers, reluctance to acknowledge that we are, as Brad Delong puts it, “jumped up East African Plains Apes”. This is especially true of philosophers, like Fodor and Nagle, who have built a career arguing that mental properties are irreducible.
