On the left is a photograph of a real snowflake. Most people would agree that it was not created intentionally, except possibly in the rather esoteric sense of being the foreseen result of the properties of water atoms in an intentionally designed universe in which water atoms were designed to have those properties. But I think most people here, ID proponents and ID critics alike, would consider that the “design” (in the sense of “pattern”) of this snowflake is neither random nor teleological. Nor, however, is it predictable in detail. Famously “no two snowflakes are alike”, yet all snowflakes have six-fold rotational symmetry. They are, to put it another way, the products of both “law” (the natural law that governs the crystalisation of water molecules) and “chance” (stochastic variation in humidity and temperature that affect the rate of growth of each arm of the crystal as it grows). We need not, to continue in Dembski’s “Explanatory Filter” framework, infer “Design”.
Three powerful commentaries on the nature of our existence:
The first is a BBC programme called The Secret Life of Waves. My father, who died earlier this year, was very keen that we should all watch it, and it helped us hugely after his death, to know that this was what he thought, and wanted to share with his children and grandchildren.
The second is a lecture someone introduced me to recently by Alan Watts, It Starts Now.
We are in a war. That is not a metaphor. We are fighting a war for the soul of Western Civilization, and we are losing, badly. In the summer of 2015 we find ourselves in a positon very similar to Great Britain’s position 75 years ago in the summer of 1940 – alone, demoralized, and besieged on all sides by a great darkness that constitutes an existential threat to freedom, justice and even rationality itself.
In this thread I don’t want to discuss the rights and wrongs of the email itself, nor of whether or not TSZ constitutes a “great darkness”. Barry is entitled to decide who posts at UD and who does not; it’s his blog.
What interests me is the perception itself, which I suspect is quite widely shared.
Since the publication of The Embodied Mind (1991), the cognitive sciences have been turning away from the mind-as-program analogy that dominated early cognitivism towards a conception of cognitive functioning as embodied in a living organism and embedded in an environment. In the past few years, important contributions to embodied-embedded cognitive science can be found in Noe (Action in Perception), Chemero (Radical Embodied Cognitive Scie Rnce), Thompson (Mind in Life), Clark (Being There and Surfing Uncertainty), and Wheeler (Reconstructing the Cognitive World).
Excerpts from a new article at Aeon by Natalie Emmons:
We see faces in the clouds and we might just see Jesus in our toast: the fact that we see anyone at all tells us that the human mind is actively searching for agents, even in the most ambiguous of situations.
…Bering and his colleagues set their sights on what psychologists call ‘intuitive mind-body dualism’ as an alternative…The study deliberately included a cluster of children too young to have been exposed to much religious testimony at all, to see whether even they had an inkling that a part of an individual survives death.
Here’s a simple thought-experiment. There’s a fire at an fertility clinic, and there is precious little time before the entire building is engulfed in flames. Down one hallway, there’s the soft purring sound of an incubator with a thousand frozen embryos; down the other hallway, the cries of a newborn baby. Which do you choose to save?
Usually, people answer “the baby” and the interesting debate then concerns why.
Questions about the existence and attributes of God form the subject matter of natural theology, which seeks to gain knowledge of the divine by relying on reason and experience of the world. Arguments in natural theology rely largely on intuitions and inferences that seem natural to us, occurring spontaneously — at the sight of a beautiful landscape, perhaps, or in wonderment at the complexity of the cosmos — even to a non-philosopher.
I have to say, while the UD “newsdesk” is terrible source for comment on scientific news, the links themselves are often interesting. Today, the UD “newsdesk” reports on a pretty interesting study, reported in Nature, here, and a preprint of which seems to be open access here
It’s been apparent for a while from Genome-Wide Association Studies (GWAS) that “risk” alleles for various mental disorders, despite being statistically significant, have extremely small effect sizes. In other words, while the studies show that many mental disorders are indeed associated with specific alleles (and we already know that many are highly heritable, including schizophrenia, ADHD and Alzheimer’s), there aren’t just a few rogue alleles of large effect (well, there are, but they are far rarer than these disorders), but instead, a whole cocktail of alleles with very slightly raised Odds Ratios for certain disorders (and some are shared between multiple disorders). This means that the vast majority of people carrying these “risk alleles” are perfectly fine. That would help explain why they have not been weeded out by selection.
Let’s discuss Amie Thomasson’s paper A Nonreductivist Solution to Mental Causation. I’ll save my thoughts for the comment thread.
He raises the question in the New York Times Sunday Review:
I believe a major change in our perspective on consciousness may be necessary, a shift from a credulous and egocentric viewpoint to a skeptical and slightly disconcerting one: namely, that we don’t actually have inner feelings in the way most of us think we do…
How does the brain go beyond processing information to become subjectively aware of information? The answer is: It doesn’t. The brain has arrived at a conclusion that is not correct. When we introspect and seem to find that ghostly thing — awareness, consciousness, the way green looks or pain feels — our cognitive machinery is accessing internal models and those models are providing information that is wrong…
1.How many of you have a song or some other piece of music “playing” in your head, right now?
2. During roughly what percentage of your waking time do you have “mental music” playing (that is, when you’re not listening to an external source of music)?
3. How much voluntary control do you have over the music playing in your head? If a song you don’t like starts to “play”, are you able to replace it with something you like better, or do you get stuck with “earworms” – songs that you can’t get rid of despite trying?
Kairosfocus has a new OP at UD entitled Putting the mind back on the table for discussion. His argument begins thus:
Starting with the principle that rocks have no dreams:
Reciprocating Bill points out that since KF denies physicalism, he has no principled basis for denying the consciousness of rocks:
If the physical states exhibited by brains, but absent in rocks, don’t account for human dreams (contemplation, etc.) then you’ve no basis for claiming rocks are devoid of dreams – at least not on the basis of the physical states present in brains and absent in rocks. Given that, on what basis do you claim that rocks don’t dream?
Needless to say, KF is squirming to avoid the question.
I’ve got popcorn in the microwave. Pull up a chair.
Humans are both very like and very different from other species we find on Earth. At the sub-cellular and biochemical level, the similarities, the almost universality of the DNA code and its property of self-duplication and storage of genetic information is breathtaking. On the other hand, no other species has succeeded in the scope and breadth of it’s colonization of this planet. Much of the “success” in growing a population that now exceeds seven billion individuals can be attributed to our being a social species. Sociability and its evolutionary roots have been well studied. However there does seem to be something missing. The rapid runaway expansion of human culture and the extraordinary flowering of human art, which might be attributed in turn to the literal expansion of the human brain seem to require further explanation.

The ‘traditional’ objections to a wholly naturalistic metaphysics, within the modern Western philosophical tradition, involve the vexed notions of freedom and consciousness. But there is, I think, a much deeper and more interesting line of criticism to naturalism, and that involves the notion of intentionality and its closely correlated notion of normativity.
What is involved in my belief that I’m drinking a beer as I type this? Well, my belief is about something — namely, the beer that I’m drinking. But what does this “aboutness” consist of? It requires, among other things, a commitment that I have undertaken — that I am prepared to respond to the appropriate sorts of challenges and criticisms of my belief. I’m willing to play the game of giving and asking for reasons, and my willingness to be so treated is central to how others regard me as their epistemic peer. But there doesn’t seem to be any way that the reason-giving game can be explained entirely in terms of the neurophysiological story of what’s going on inside my cranium. That neurophysiological story is a story of is the case, and the reason-giving story is essentially a normative story — of what ought to be the case.
And if Hume is right — as he certainly seems to be! — in saying that one cannot derive an ought-statement from an is-statement,and if naturalism is an entirely descriptive/explanatory story that has no room for norms, then in light of the central role that norms play in human life (including their role in belief, desire, perception, and action), it is reasonable to conclude that naturalism cannot be right.
(Of course, it does not follow from this that any version of theism or ‘supernaturalism’ must be right, either.)
Folks who believe in an immaterial soul (also known as ‘substance dualists’) face a daunting challenge. Why, if our mental and emotional functions are carried out by the immaterial soul, are they so completely affected by changes to the physical brain?
Alvin Plantinga is widely regarded as one of the world’s leading Christian philosophers. Watch the video below and ask yourself, WTF?
So as not to spoil your fun, I’ll refrain from offering my take on the argument until readers have had a chance to comment.
We all have biases that we should try to be aware of. Our implicit prejudices may be at odds with our explicit attitudes. One problem when discussing issues such as racism and sexism especially is that surprisingly many people seem to think that such things have been largely dealt with in the 20th Century and are now of minimal importance.
https://implicit.harvard.edu has several tests designed to measure our implicit biases. As with any scientific test, there could be issues with methodology etc and, in addition to discussion of implicit biases (e.g. the psychology of them, how they affect our skepticism), that also seems an appropriate topic for discussion here.
There’s a nice little discussion going on at Uncommon Descent (see here) about whether concepts are consistent with naturalism (broadly conceived). Here I want to say a bit about what theories of concepts seem to me to be most promising, and to what extent (if any) they are compatible with naturalism (broadly conceived).
The dominant position in philosophy of language treats concepts as representations: I have a concept of *dog* insofar as I am able to correctly represent all dogs as dogs. It is crucial that concepts have the right kind of generality — that I am able to classify all particular dogs as exemplifying the same general property — in order to properly credit me with having the concept. (If I only applied the term “dog” to my dog, it would be right to say that I don’t really have the concept *dog*.)
On the representationalist paradigm, rational thought has a bottom-up structure: terms are applied to particulars, terms are combined to form judgments about particulars, and judgments are combined to form arguments, explanations, and other forms of reasoning.
From a comment I made last year at UD:
It’s impossible to verify the reliability of a cognitive system from the inside. Why? Because you have to use the cognitive system itself in order to verify its reliability.
If the system isn’t reliable, you might mistakenly conclude that it is!
This even applies to God himself. From the inside, God may think that he’s omniscient and omnipotent. He seems to know everything about reality, and he seems to be able to do anything that is logically possible. But how can he know these things with absolute certainty?
What if there is a higher-level God, or demon, who is deceiving him into thinking that he’s the master of the universe when he really isn’t? How, for that matter, can God be sure that he isn’t a brain in a vat?
He can’t. Defining him as omniscient doesn’t help. Like everyone else, he can only try to determine, from the inside, whether his cognitive apparatus is reliable. He can never be absolutely sure that he isn’t being fooled, or fooling himself.
