Is common sense merely plausible?

This week I’m going to continue the discussion of “common sense” from two weeks ago. I think it’s an important discussion because an overreliance on the concept of “common sense” can be (and seems to have been repeatedly) used to challenge the value and viability not merely of “religion” but of philosophy itself. I’m going to assume that readers of this current post have read that previous post – but not that they have read the comments on it, which have been the most numerous of any post on this blog so far (a full hundred!)

In those comments I challenged Thill to define the term “reliable,” which he had previously introduced to the discussion. I structured the post around the term “reliable” because in Thill’s previous comment, it had been at the centre of his only serious response to the point that “common sense” can be wrong (as in the case of sunrise and sunset). He said: “The fact that it is not infallible does not support the conclusion that it is not reliable!” No doubt I should have probed the definition of “reliable” further in the post – examining what Thill could have meant by it; I did not. I tried to make up for that lack in a later comment, where I asked Thill to define “reliable.” Thill responded that the onus was on me to define “reliable” since I had advanced a thesis relating to it; but my supposed thesis was intended as a response to his own thesis about the reliability of common sense, a word which, again, he introduced to the discussion. So I noted that I am happy to drop the term from the discussion as long as he, too, is willing to refrain from using the term “reliable” to refer to the epistemological status of so-called common sense. (That also applies to the others, Jabali108 and Neocarvaka, who have been exalting “common sense” in recent discussions.)

If we drop “reliable,” where are we left? 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 →

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 →

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 →

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.

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 →
