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 →

The problem with the trolley

Suppose a trolley is hurtling down a track, on which are placed five innocent people with no chance to escape in time. You are standing beside a switch that will redirect the trolley onto a track where stands one innocent person, who also has no chance to escape. Should you flip the switch, and thereby kill one to save five?

Now suppose there is no track onto which the trolley can be redirected; the five innocents will be in its path no matter what happens. Instead of being beside a switch, you are standing on a bridge over the tracks, beside a very fat man looking down over the action. You can push the man over the bridge, knowing his enormous girth will stop the trolley’s movement before it hits the innocents. Should you push the man, and thereby kill one to save five?

Michael Sandel begins his famous course on Justice with this action scene, and it’s a great way to start such a course. This trolley problem, ingeniously introduced by Judith Jarvis Thomson and the late Philippa Foot, is a wonderful way to shock beginning students out of their ethical complacency. For nearly all people faced with this problem agree they would kill one to save five in the first situation but not the second. After hearing one case they think there’s an easy principle by which to decide the right action; after hearing the second, they are forced to admit that there isn’t. Continue reading →

Skepticism in two directions

I attended a great panel yesterday at the Eastern APA. Two of the presentations addressed each other directly on a topic I’ve discussed before: skepticism in Indian thought. The presenters, Ethan Mills and Laura Guererro of the University of New Mexico, had clearly been engaged in a longstanding debate with each other on the subject beforehand, which I think helped sharpen their thoughts nicely for the talk.

Mills presented on Jayarāśi, whose Tattvopaplavasiṃha (“The Lion that Afflicts Categories”) is the only extant full text attributed to a member of the Cārvāka-Lokāyata, the atheist and materialist school of ancient Indian thought. But Jayarāśi takes the Cārvāka school’s thought much further than it is usually thought to go. Whereas this materialist school is normally understood to merely deny the existence of gods and karma, Jayarāśi denies the existence of pretty much everything. Previous Cārvākas were said to believe that the world was made up entirely of the four elements; Jayarāśi says, “Even the view of world as elements is not well established. How much less are all the others?” He is, in short, a skeptic. 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 →

Certainty requires omniscience

Under what circumstances can one be absolutely certain of anything? I had intended my previous post to be on that question, but the preliminary inquiries to it were significant enough that I thought they deserved their own post. I end that post, like the earlier “Certain knowledge” post, on a note of uncertainty; I don’t discuss any circumstances under which certainty is possible. So is it possible at all?

I generally lean toward saying no – and an uncertain no. I leave the possibility open that something will be revealed to me that I can be absolutely certain of; but I don’t think one exists. The happy thing about this kind of uncertainty is there’s no contradiction in it. While “there is no truth” is a contradiction because it asserts that the truth is there is no truth, and “we cannot know anything” is a contradiction because it implies that it can be known that nothing can be known, the same is not true about “we cannot be certain about anything.” The last can be asserted as a statement that is merely highly probable; it doesn’t need to be certain to be true, and therefore can be true without contradicting itself.

Still, I do think there’s one circumstance where real certainty is possible – though it is merely a hypothetical circumstance. Continue reading →

I’d like to say some more about questions of doubt and certainty, which were central to my recent discussion of Wittgenstein. I explored this question at greatest length in the post called “Certain knowledge”, but the conclusions there were tentative – which is to say, not certain.

To recap a little first: This question was Descartes‘s biggest passion. He wanted one and only one Archimedean point, one firm foundation that could not be doubted, on which he could build the rest of his philosophy. And to doubt that he was doubting would be self-contradictory, so the existence of his doubt and therefore of his own existence became certain. “I think, therefore I am.”

But Descartes was wrong: the existence of the thinking self can be, and is, doubted all the time. Almost all Buddhist tradition rests on just such a doubt: the self is not real. If there is an indubitable Cartesian foundation, one must take it back to “There is thinking, therefore there is being.” But is there even this? Descartes argues that to doubt one’s own doubt (or doubt one’s own thinking) is self-contradictory. To establish this point for certain, however, does require that one accept the logic law of non-contradiction – and accept it as an absolute law, brooking no exceptions ever. Graham Priest’s dialetheist epistemology denies this very point: only by allowing that certain contradictions can be true, he says, can we successfully resolve the liar paradox or Zeno’s paradoxes.

The bewitching Wittgenstein

In the previous post I noted that I am completely unimpressed by Ludwig Wittgenstein’s On Certainty. What I know of the rest of his work, at least the Philosophical Investigations, has done little to impress me either. (Most of what I read serves to convince me more strongly that he is wrong.)

I suppose I’ve long been predisposed against Wittgenstein because of the unfortunate ways his thought is used in religious studies. Continue reading →

A quick look at On Certainty

It is probably uncontroversial to describe Ludwig Wittgenstein as one of the twentieth century’s greatest philosophers. In my less charitable moods I’d be tempted to say that this is rather like being one of Kansas City’s tallest buildings. Still, his vast influence over the philosophies that come after him is undeniable – but I often wonder why.

I’m led to think about Wittgenstein by a few recent comments from Thill, quoting a text called On Certainty. Readers might recall that in my most extensive reading of Wittgenstein to date – looking at the Philosophical Investigations – the main effect he had on my thought was to push me away from his thought and closer to the thinkers he disliked, like Plato and Augustine. But a brief look at On Certainty does even less for my estimation of Wittgenstein as a thinker. Continue reading →

The inadequacy of primary theory

Last time, I accepted that there were two reasonable ways to define “common sense.” One can identify it with prejudices, as I did the first time around, so that common sense is what is held to be common and taken for granted by a given group of people (usually one’s own). Alternately, one can identify common sense with Robin Horton’s “primary theory”: the kind of description or explanation of human experience that is basic enough to be mostly universal, such as plants requiring water to grow. Primary theory is opposed to more complex “secondary theory” like witchcraft or subatomic physics, referring to unseen phenomena, which explains events anomalous to primary theory and is not at all universal.

Now if common sense is defined as primary theory, what then is its philosophical significance? Far less, I would argue, than is often claimed for “common sense.” The problems with primary theory are twofold: first, it is relatively limited in scope; and second, it is often wrong.

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 →
