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 →

Science is not common sense

Thill replies to my post about common sense in a reasonable way: by challenging the definition. In that post I have identified common sense as consisting merely of the prejudices common to any given age. Thill is right to protest that unmodified common sense, thus defined, will likely have few defenders (with the possible exception of Robert Goodin); and I did relatively little to defend my definition in that post. So it’s worth examining Thill’s alternative definition. Continue reading →

The universalism of multiple Buddhas

Alasdair MacIntyre, especially in his Three Rival Versions of Moral Inquiry, has frequently tried to make the case that adequate moral inquiry needs to be embedded within a tradition. In the book he makes the case by arguing that Pope Leo XIII’s encyclical Aeterni Patris shows a fuller and more adequate understanding of the attempts to get beyond tradition (Nietzsche’s genealogy and the Ninth Edition of Encyclopedia Britannica) than they show of themselves or each other. I’m not going to address the details of his case here. But I want to note one point that MacIntyre frequently seems to shy away from: for Leo XIII and the Catholic tradition that precedes him, it is not the case that adequate moral inquiry must take place within a tradition. Rather, it must take place within this tradition, the universal and apostolic Catholic Church. The inquiries of the Confucians or Muslims are not significantly better, in this respect, than those of deracinated cosmopolitans like the Encyclopedists or Nietzsche.

In this, MacIntyre skirts around on an idea that endures through the history of the Abrahamic traditions: that the ultimate truth is tied to one single historical event, time, place and/or people. It begins with the idea recorded in the Book of Exodus that the Hebrews/Israelites/Jews are God’s chosen people, and continues with the idea that the single human person Jesus of Nazareth was the only begotten human son of God. The Qur’an, too, is a single set of revelations made in a small geographic area to one human person, not adequately translatable (so the claim goes) into a language other than the original, which is better than any other revelation that has been or will be made.

It is in this context that I am intrigued by the Buddhist claim that there are multiple buddhas. Continue reading →

From supernatural to unscientific

A comment from Thill on a recent post makes me reconsider the category of the supernatural, which I’ve employed many times on this blog. It’s been an important category in my reflection because I acknowledge the normative weight of natural science, and am suspicious of claims that contradict its findings. When Śāntideva tells us that advanced bodhisattvas can fire rays from their pores that make the blind see and make malodorous people smell better, I have reason to disbelieve him. The idea of rebirth – at least in the straightforward way Śāntideva portrays it, with bad people getting reborn in hells – makes me similarly suspicious, which is one reason I’ve been so sympathetic to Dale Wright’s project of naturalizing karma.

On faith in tooth relics

Pha That Luang in Laos, said to contain the Buddha's breast bone Via a Buddhist group at Harvard, I just saw an interesting article from Singapore in 2007, about the tooth relic located in a Singapore temple. For those who are unfamiliar, Buddhists (especially Theravādins) often venerate items said to have come from the Buddha’s body – his hair, nails, teeth. They are housed in stūpas, the tall, pointy and/or circular towers typically located in Buddhist temple grounds.

To a Western audience, at least, this phenomenon provokes an obvious question: did these relics actually come from the Buddha’s body? And in many cases – certainly the case of this Singapore temple – any serious empirical investigation can establish the answer as a pretty clear no. Continue reading →

Looking for coherent authorship

On my dissertation committee, Janet Gyatso always had perceptive comments to make, usually coming from many different directions. The one line of criticism that she pursued throughout the dissertation process was about authorship: she was visibly dissatisfied that I had chosen to pursue the diss as a study of a single author, Śāntideva. The point extended beyond my dissertation as well: early on in my PhD, I gave her a paper that explained it would treat the Yoga Sūtras together with their Yoga Bhāṣya commentary as an “internally coherent,” and she commented “you can’t do that.” In other classes focused on reading texts, she would tell her students that the class would not look for coherence – they would not be asking questions of the form “if the text says x here, how can it say y over here when the two contradict each other?”

One can always argue the details of this textual question in any given case. In Śāntideva’s case it’s not only a matter of arguing whether “his” two major works (the Bodhicaryāvatāra and the Śikṣā Samuccaya) were written by the same person; it’s also the fact that these texts may themselves be the work of multiple writers, in that there’s an early version of the Bodhicaryāvatāra (the “Dunhuang recension”) which differs from the received version known to tradition. But there’s an issue here much bigger than the interpretation of any one thinker: should one even try to find the coherent views of an individual author? Continue reading →

Why we should ask what science is

Since my post on Pierre Hadot, I’ve come to realize that genuinely philosophical thought today must include elements of the domains usually called “religion” and “science” (and that those two domains must overlap to some degree). Having done a degree in religious studies, I’ve thought through the concept of “religion” a lot – mostly to identify what a misleading category it is, though of course the phenomena it typically points to matter a lot.

But what about science? It’s intriguing to me that for one of the most highly regarded philosophers of science, Karl Popper, the central problem in philosophy of science is demarcation. That is to say, for Popper, the most important thing philosophy of science needs to do is to distinguish science from non-science.

At first this seems an oddly defensive position to take. Compare “philosophy of science” in this regard to “philosophy of religion.” Continue reading →

Not all facts are empirical

There’s been a fair bit of blogosphere buzz about Sam Harris‘s recent TED talk, entitled “Science can answer moral questions.” I didn’t expect to agree much with Harris, given my usual objections to empiricist scientism and related attempts to exalt “science” against “religion.” And I think there are indeed a number of problems with Harris’s view. And yet there’s quite a lot that Harris gets right – at least as much, I think, as most of his critics.

The most widely read response to Harris (and the one that Harris himself responded to at length) is one by Sean Carroll. I find the Harris-Carroll debate instructive because both seem to miss the most important point; and that, in turn, would seem to be because both fall prey to an unfortunate empiricism.

At the heart of the debate is the supposed dichotomy between “facts” and “values,” or “is” and “ought.” (I would rather say “should” than “ought,” because “ought” sounds increasingly rare and archaic in contemporary North American English, but that’s a quibble.) Harris insists that values are a kind of fact, even objective fact, so that “should” or “ought” statements have a meaning grounded in reality, not entirely relative to or dependent upon the subjects making the claim. “Should” statements, on this view, are a kind of “is” statement. In this, I think, Harris is entirely right.

Where Harris slips up is in missing the elision of “fact” with “empirical fact.” Continue reading →
