Value as proof of God

The posts of the previous couple weeks begin to add up to an argument for the existence of something like God – a value or goodness that is an inextricable part of the basic structure of reality. It strikes me that a significant part of this line of reasoning also underlies most of the widely known philosophical proofs for the existence of God. These proofs (at least on their own) do not take us to any of the particular Abrahamic views of God, as revealed in Qur’an or Torah or the person of Jesus Christ, but they are often taken as a first step to getting there.

Why evolution doesn’t explain value

I’ll be the first to admit that last week’s post was insufficiently argued. But I think it may have been helpful as a springboard for further (potentially more carefully argued) reflection; I expect that next week’s post, as well as this one, will follow up on it. I argued last week that attempts to explain value judgements seem to run into trouble when they don’t ground those judgements in a deeper metaphysical reality. I looked at this problem there largely in terms of the early twentieth-century analytic tradition. But I didn’t address one of the most common non-metaphysical attempts to explain value judgements: the evolutionary explanation.

Several comments from Jesse took this approach. “Morality,” he claims, “has existed in some form or other since the first self-replicating proteins formed in the primordial ocean.” Citing game theory, he notes that organisms which helped each other out would have been far more likely to survive and thrive. Ethan Mills, while somewhat skeptical of the game-theoretic explanation, still cites James Rachels for another kind of evolutionary explanation: at the social rather than individual level, societies wouldn’t have lasted long without morality.

Now I am not and was not speaking only of “morality” in the sense of aiding (or refusing to harm) others. (There was a reason the word “morality” didn’t appear in that post.) As I noted in my comment, I was also speaking of other kinds of value – including virtues like self-discipline and patient endurance that would be valuable whether or not anyone else is around, and for that matter of aesthetic value, the value in good art or the beauty of nature.

But that’s not the big issue here, for it’s not so hard to come up with evolutionary explanations for these other kinds of value either. Self-disciplined creatures would very likely have adapted better to their environments. There are plenty of people, perhaps most notably Denis Dutton, who have even tried to find evolutionary explanations for aesthetics.

I am not going to pass judgement here on whether evolution is a correct or adequate causal explanation for the origins of human value judgements. For the sake of argument, in this post, I am going to assume that such accounts get the causal origin of value judgements basically correct. Because far more important is a deeper criticism: they miss the point. Continue reading →

How may we tell true from false?

How can we, or should we, learn what is true and what is false? This is one of the most enduring and basic questions in philosophy – “basic” because it is fundamental to so many others, not because the answers are in any way easy or simple.

The question, or some form of it, came up a number of times in recent discussions of “common sense”: if common sense isn’t reliable, I was asked, what is? I’m going to try to avoid the word “reliable” as I think its different uses became confusing in the previous debate; I have little stake in its use as a term. But the basic question of determining truth from falsehood is a crucial one and worth asking.

That’s not to say, however, that it admits easy answers, for I don’t think we should expect easy answers on the most basic philosophical questions. Continue reading →

Of the plausibility or reliability of “common sense”

This week, another foray into the debate over “common sense.” Apologies in advance to those readers who are not interested in this particular topic, or who will find this post’s precision rough going. Common-sense advocate Thill has been by far this blog’s most prolific commenter, and I think advancing the debates in the comments requires taking his views on directly and systematically. Moreover, I think the topic is an important one in its own right. The claims made by Thill, Jabali108, Neocarvaka and Ramachandra1008 in their comments, if they were true, would rule out the vast majority of South Asian philosophical thought (and a great more besides): probably all the philosophy originating in the subcontinent except for the shadowy Cārvāka-Lokāyata school of thought. Only the Cārvākas can be thought to completely exclude “religious” ideas from their worldview; but there is little if anything left to be learned from this school now, since all we have from them is the scantest of fragments. (The only surviving complete text attributed to a Cārvāka is Jayarāśi’s Tattvopaplavasiṃha, which these commenters have already dismissed as not really a Cārvāka text.) If South Asian thought is worth bothering with at all, then we’ll need to defend those conceptions of the world that are in some respects at odds with various elements of “common sense” – which, according to Thill, excludes all “religion.” Continue reading →

Lack of training is not reliable

Several of this blog’s frequent commenters find significant philosophical value in the concept of “common sense,” and find it helpful to refute a claim on the grounds that the claim contradicts “common sense.” These commenters include not only Thill, whom I challenged on the topic several times before, but Jabali108 and Neocarvaka. (See the comments on this post for examples.) So the concept is worth revisiting if those debates are to get anywhere.

Let me start out by noting that I see some philosophical value in appeals to common sense defined in a certain way. This is the sense that I outlined in my first post on the topic: the prejudgements one brings to a given inquiry, especially as they come out of shared assumptions of one’s own society. My commenters seem to have something quite different in mind, however. Continue reading →

On the genealogy of “Buddhism and science”

The most recent book from Donald S. Lopez, Jr., one of the most widely read contemporary American scholars of Buddhism, is entitled Buddhism and Science. Unlike most books with this title, it does not explore similarities or complementarities between Buddhist tradition and the natural sciences. It is instead best described by Lopez’s original intended subtitle: A Historical Critique. Alas, Lopez’s publishers apparently thought this subtitle boring, and therefore required him to replace it; his chosen replacement, A Guide for the Perplexed, is not particularly exciting either, and more importantly makes it impossible for the casual reader to find out the ways that this book is drastically different from all the other books out there with the same title.

I am not here to write about dreadful editorial decisions, however, but rather the content of the book. Lopez undertakes what has become one of the most standard methodologies in the contemporary academic humanities: following Foucault and ultimately Nietzsche, it is typically known as genealogy. One starts with a widely used contemporary concept and goes on to show the history of its usage, in order to create doubts among those who might otherwise use it. This has already been done plenty of times both for the concepts of “Buddhism” and of “science”; Lopez’s project here is instead a genealogy of the joint concept of “Buddhism and science,” the frequent form of inquiry that tries to link the two conceptually or analytically. As is typical for contemporary genealogies ever since Edward Said (though not for Foucault’s own and certainly not Nietzsche’s), Lopez finds the origins of “Buddhism and science” in the colonial nineteenth century. He shows us that claims about Buddhism’s compatibility with science remain remarkably consistent from the late 19th century to the early 21st, even though the science itself has changed drastically.

Now what is the purpose of showing us this point? From Nietzsche onward, the genealogical method has never been neutral. The point has always been to undermine. Lopez doesn’t like “Buddhism and science” any more than Nietzsche liked morality. Continue reading →

Can collectivities be virtuous?

There’s been a great discussion going on in the comments to last week’s post on humility and science. This week I’m going to focus on only one of the themes mentioned, which takes us in a different direction from that post but is interesting in its own right.

My post recounted Carl Sagan’s claim that although “religions” claimed an ideal of humility, science was actually more humble; I argued that the two were in fact very similar. A comment from Ben acutely pointed out something I had been missing, a way in which Sagan was right that the tradition was different. Sagan, Ben points out, is defending “not the humility of individuals, but the humility of the whole tradition.” Science as a whole is able to admit when it is wrong, in a way that Christianity and Buddhism are not. In a following dialogue, Ben and I agree that science maintains an institutional humility that “religious” traditions do not, though those other traditions likely do a better job of promoting individual humility.

Other commenters took issue with this agreement, however. If you follow the comment threads on this site with any regularity, you will know that Thill and Jim Wilton do not usually agree on very much. But this time, they unanimously condemn the point shared by Ben and myself: “There is a category mistake here,” says Thill. “Traditions cannot be said to be humble or arrogant. Only individuals can be said to be humble or arrogant.”

And this is a question that well deserves further philosophical exploration. Can an institution or a tradition possess a virtue? Can a government be courageous? Can a corporation be honest? Can a tradition be humble? Continue reading →

Humility in science and other traditions

I’ve lately been reading and enjoying The Demon-Haunted World, Carl Sagan‘s manifesto against pseudoscientifc beliefs (such as alien abductions). One of the more enjoyable and thought-provoking sections of the book is a discussion of scientists’ humility: “I maintain that science is part and parcel humility. Scientists do not seek to impose their needs and wants on Nature, but instead humbly interrogate Nature and take seriously what they find. We are aware that revered scientists have been wrong. We understand human imperfection.” (32) The ideal scientist humbles herself before the truths about the natural world that she finds in her work. He quotes his wife Ann Druyan to the effect that science “is forever whispering in our ears, ‘Remember, you’re very new at this. You might be mistaken. You’ve been wrong before.'” (34-5) I hadn’t thought of science in these terms before, but I think Sagan is quite right about this – to an extent, as I’ll discuss below. Sagan repeatedly and rightly stresses the importance of uncertainty for a scientist; to live up to the ideals of scientific research requires the ability to admit we are wrong. A scientist must never be too confident in her own rightness; what first seems obvious is often exactly what turns out to be wrong, overthrown by the evidence. I think this is excellent advice for scientists to follow – or anyone else.

After quoting Druyan, Sagan proceeds immediately to add: “Despite all the talk of humility, show me something comparable in religion.” And this is where he goes astray. Continue reading →

Descriptive and normative meanings of science and other traditions

I’ve been wanting to follow up on an earlier post and ask just what science, natural science, really is. I realize that the concept “science” has two separate and distinguishable, though related, meanings. On one hand, “science” has a normative meaning – it names an ideal, of how our investigations into the empirical world should be conducted. On the other, it has a descriptive meaning – it names a set of institutions with a history, inhabited by fallible human beings who, often as not, fail to live up to that ideal even though they are supposed to live up to it.

The first, normative meaning is the one with the most philosophical significance. This is the one with normative weight; it is in this sense that, if we call something unscientific, we are saying something bad about it. I haven’t pinned down the details of this normative sense as much as I’d like yet, but I think it involves testing falsifiable hypotheses, making controlled experiments, controlling for variables, and above all rejecting hypotheses that turn out to be falsified. I expect to say more about this normative sense of science in the near future.

Overall I think it is that first (normative) sense of science that’s most relevant to philosophical inquiry, inquiry about the nature of reality and how we should live in it. But the second sense also matters, if only because we need to isolate it as a way of understanding the first. In this descriptive sense, science is what scientists do, and scientists are people who have been trained in academic science departments. This is the realm where scientists fudge data to fit their own political agenda or that of their corporate funders. It is also what Thomas Kuhn famously catalogued in his The Structure of Scientific Revolutions, where the consensus among scientists moves much more randomly and haphazardly than the normative ideal should indicate. There is something about science in the first sense that is (I would argue) inherently good; this is not the case about science in the second sense. A man who has a PhD in biology but regularly falsifies data to fit his preconceptions is a scientist in only the second (descriptive) sense, not the first (normative) sense.

What strikes me about this distinction, though, is that much the same distinction could be made about any given “religion.” Continue reading →

Is there certainty beyond logic?

Responding to my post on doubt, Jim Wilton agreed that “truth established through thought and logic is always subject to doubt.” But he suggested that not all knowledge or truth is a product of logic – and, he claimed, perhaps this non-logical knowledge can be certain, indubitable.

I agree that not all knowledge is a product of logic. This is one of the reasons I have spent a great deal of time discussing what Thomas Kasulis calls intimacy worldviews, background approaches to philosophy that are not derived from direct argument. I agree with the thinkers in such traditions that truth is not merely something expressed in linguistic propositions.

Where I disagree strongly, however, is on the view that such non-logical knowledge can be a source of genuine certainty. Continue reading →
