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.

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 →

Monotheists’ humility

I’ve been thinking some more about the idea of encounter, which I blogged about in these posts and which I take to be central to the philosophy of Emmanuel Lévinas: the idea that we can never encompass the wholeness of truth, it must remain irreducibly other to us. I’m wondering whether the basic idea animating encounter philosophies is the virtue of humility – a virtue, I think, in both epistemological and ethical contexts. Aristotle, on the other hand, saw pride as a virtue, modesty as its lack – and while I do think humility is a virtue myself, I would remain an Aristotelian in seeing humility, like justice, as a mean. It is far too easy to be too humble in action, to be servile and self-abnegating – an excess which, I’ve suggested before, hurts women’s struggle for equality. And with respect to knowledge, too little humility can lead us to an inappropriate feeling of certainty; but realizing that lack of certainty can spur us to too much humility, leading us into a self-contradictory denial of truth and knowledge.

The issue surrounding encounter, in that case, goes well beyond one’s relationship with God, even one’s relationship with other human beings. Continue reading →

Following science as a layperson

Perhaps the trickiest thing about trying to be a philosopher today is the explosion of information in natural science: we are in the era of “rapid-discovery science,” as Randall Collins calls it in The Sociology of Philosophies. Aristotle could write not merely a Metaphysics but a Physics, and his wide range of general knowledge was enough to make him one of the experts on the subject. Even as recently as the 19th century, Schelling and Hegel could have a decent shot at writing “philosophies of nature,” in which they tried to think philosophically through the whole scope of the way the natural world works. But today, not even a professor of natural science can know all the science that’s out there, even in relatively general terms. To some extent, we need to rely on the authority of experts we trust to know their fields well – what Indian philosophers called the śabdapramāṇa, the source of knowledge beyond inference and personal experience. And even if we somehow could know all the science for a moment, we’d lose it almost instantly as the science changes. Continue reading →

Omniscience and manipulation

Andrew Moon of the Prosblogion (probably the leading blog in the philosophy of Abrahamic traditions) was recently rereading Robert Adams’s The Virtue of Faith, and was intrigued by a passage that I also found intriguing. Adams is arguing that uncertainty is a central part of a good personal relationship:

Well, suppose we always saw what people were like, and particularly what they would do in any situation in which we might have to do with them. How would we relate to people if we had such knowledge of them? I think we would manipulate them. I do not mean that we would necessarily treat people in a selfish or immoral way, but I think we could not help having an attitude of control toward them. And I think the necessity we would be under, to have such an attitude, would be conceptual and not merely causal. If I pursued my own ends in relation to you, knowing exactly how you would respond to every move, I would be manipulating you as much as I manipulate a typewriter or any other inanimate object.

Against “non-overlapping magisteria”

“Religion” and “science” are typically held to be opposing worldviews, especially in the United States where they identify two sides of a cultural divide (such that Jesus fish and Darwin fish are as common on American cars as are bumper stickers). For those of us who are trying to learn from both, it often seems like a relief to hear compromises like the late Stephen Jay Gould’s theory of “non-overlapping magisteria” (abbreviated NOMA). Briefly, in effect, Gould says that there is no need for conflict between science and religion, because science deals with questions of fact and religion with questions of value (or of “moral meaning”). Ken Wilber puts forward a slightly more sophisticated version of the non-overlapping magisteria view:

Simply imagine what would happen if we indeed said that modern physics support mysticism. What happens, for example, if we say that today’s physics is in perfect agreement with Buddha’s enlightenment? What happens when tomorrow’s physics supplants or replaces today’s physics (which it most definitely will)? Does poor Buddha then lose his enlightenment? You see the problem. If you hook your God to today’s physics, then when that physics slips, that God slips with it. (from Grace and Grit, p. 20)

Gould’s claim would be a great way of resolving the conflicts between science and religion – if it were true. The problem is that it isn’t. Continue reading →

Certain knowledge

I recently had an extraordinarily stimulating conversation with two friends who wish to remain anonymous (but they know who they are). The topic: can we ever have certain knowledge about anything? My initial response, not intended to be flippant, was: I’m not certain.

The MatrixThe friends claimed certainty about things that I don’t think we can reasonably be certain about. One claimed to have achieved certain knowledge through the Sufi practice of dhikr; I argued that this could be a feeling of certainty about falsehood rather than about truth, so that one needs standards of truth external to the mystical experience. The other claimed that we could know with certainty that we are awake and not sleeping; I wasn’t ready to grant that. I’m ready to grant the basic point of Descartes’s skepticism: although we can be relatively confident that the things of the world are as they seem, it’s possible they could all be a dream, or the creation of an evil demon – or even the Matrix. (What a gift that movie is to teachers of introductory philosophy!)

Now Descartes himself thinks he can have certain knowledge in spite of all this doubt, or in a certain sense even because of it: he believes that the one thing he can’t doubt is the fact that he is doubting. His doubt would be logically self-contradictory, for its very existence would require the presence of a doubter, namely himself. Thus, “I think therefore I am” (cogito ergo sum).

My Buddhist readers will probably be unsympathetic to Descartes’s argument, and rightly so. Descartes tries here to prove the very thing that the Buddha of the Pali suttas – and the vast majority of later Buddhists – would be at pains to deny, namely the existence of the self. I would argue that a Buddhist critique knocks Descartes down quite effectively. Descartes may have established the existence of doubt, but not of an agent of doubt, of a doubter. That’s an error, a reification. As a popular book on Buddhism has it, there are thoughts without a thinker. Even if one disagrees with Buddhist deconstructions of the self – and I am often skeptical of them – one must surely still acknowledge that they at least cast doubt on the self, the thing Descartes thought could not be doubted.

Nevertheless, there’s a route to certain knowledge that one can still follow from here. Continue reading →
