More on Dialectic

In Book I of Plato’s Republic, Socrates distinguishes between two ways to respond to a disagreement. The two parties can:

  1. Have a debate, to be judged by a third party.
  2. Work with one another to resolve the disagreement.

The latter would seem to be dialectic, although Socrates does not call it that. I said this last time, when I also noted that Socrates does refer to dialectic as such in Book V; but I deferred investigation of the passage till now.

On Dialectic

This is about dialectic in Plato’s Republic and today. There’s a lot here, and in another post I may investigate why that is; meanwhile, I note words of Serge Lang (1927–2005) in the Foreward of Algebra (third edition, 1993):

Unfortunately, a book must be projected in a totally ordered way on the page axis, but that’s not the way mathematics “is”, so readers have to make choices how to reset certain topics in parallel for themselves, rather than in succession.

From socialism to liberalism and perhaps back

The word “dialectic” has the air of a technical term. It intimidated me in the eighth grade, when I chose communism as my topic for a paper in political geography, and I found myself consulting a big book on dialectical materialism. My main source ended up being the Communist Manifesto, which says nothing of dialectic as such.

The Manifesto may take up dialectic implicitly, as by saying in the beginning,

Freeman and slave, patrician and plebeian, lord and serf, guild-master and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary reconstitution of society at large, or in the common ruin of the contending classes.

Perhaps one would refer to the ongoing fight between oppressor and oppressed as dialectical. However, dialogue being conversation, I take dialectic to be the art of conversing; fighting is something else.

Pacifism

Pacifism is properly pacificism, the making of peace: not a belief or an attitude, but a practice. Mathematics then is pacifist, because learning it means learning that you cannot fight your way to the truth. Might does not make right. If others are going to agree with you, they will have to do it freely. Moreover, you cannot rest until they do agree with you, if you’ve got a piece of mathematics that you think is right; for you could be wrong, if others don’t agree.

Articles on Collingwood

This article gathers, and in some cases quotes and examines, popular articles about R. G. Collingwood (1889–1943).

  • By articles, I mean not blog posts like mine and others’, but essays by professionals in publications that have editors.

  • By popular, I mean written not for other professionals, but for the laity.

Map of Art

The bulk of this post is a summary of the chapter on art in Collingwood’s Speculum Mentis: or The Map of Knowledge (1924). The motto of the book is the first clause of I Corinthians 13:12:

Βλέπομεν γὰρ ἄρτι δι’ ἐσόπτρου ἐν αἰνίγματι

For now we see through a glass, darkly

The chapter “Art” has eight sections:

Reading shallow and deep

Executive summary (added July 28, 2020): I read an article praising so-called deep reading, one of whose exponents is Henry Kissinger. The world is apparently being corrupted by people who do not read deeply; and this includes ourselves, if we allow ourselves to be distracted by social media. I myself find the article corrupted by references to neuroscience, and I am sorry that the writer, Adam Garfinkle, does not tell us about his own experience of reading. His article comes recommended by George Will, whose tenure at the Washington Post can be blamed on my grandfather. I reminisce about him and about my own deep or at least long reading, in college and more recently. I take a hedonistic view of this reading.

Seeing a tweet condemning the superficiality of Twitter, I could not pass up the challenge. I read the linked essay, “What we lost when we stopped reading” (The Washington Post, April 17, 2020). That was by George Will, summarizing and recommending a longer essay, by Adam Garfinkle, “The Erosion of Deep Literacy” (National Affairs, number 43, spring 2020). I read that, yesterday evening and this morning (April 21, 2020).

Doing and Suffering

To do injustice is worse than to suffer it. Socrates proves this to Polus and Callicles in the dialogue of Plato called the Gorgias.

I wish to review the proofs, because I think they are correct, and their result is worth knowing.

Loeb Plato III cover

Or is the result already clear to everybody?

Whom would you rather be: a Muslim in India, under attack by a Hindu mob, or a member of that mob?

You would rather not be involved; but if you had to choose, which option would be less bad: to be driven to an insane murderous fury, or to be the object of that fury?

Anthropology of Mathematics

This essay was long when originally published; now, on November 30, 2019, I have made it longer, in an attempt to clarify some points.

The essay begins with two brief quotations, from Collingwood and Pirsig respectively, about what it takes to know people.

  • The Pirsig quote is from Lila, which is somewhat interesting as a novel, but naive about metaphysics; it might have benefited from an understanding of Collingwood’s Essay on Metaphysics.

  • A recent article by Ray Monk in Prospect seems to justify my interest in Collingwood; eventually I have a look at the article.

Ideas that come up along the way include the following.

  1. For C. S. Lewis, the reality of moral truth shows there is something beyond the scope of natural science.

  2. I say the same for mathematical truth.

  3. Truths we learn as children are open to question. In their educational childhoods, mathematicians have often learned wrongly the techniques of induction and recursion.

  4. The philosophical thesis of physicalism is of doubtful value.

  5. Mathematicians and philosophers who ape them (as in a particular definition of physicalism) use “iff” needlessly.

  6. A pair of mathematicians who use “iff” needlessly seem also to misunderstand induction and recursion.

  7. Their work is nonetheless admirable, like the famous expression of universal equality by the slave-driving Thomas Jefferson.

  8. Mathematical truth is discovered and confirmed by thought.

  9. Truth is a product of every kind of science; it is not an object of natural science.

  10. The distinction between thinking and feeling is a theme of Collingwood.

  11. In particular, thought is self-critical: it judges whether itself is going well.

  12. Students of mathematics must learn their right to judge what is correct, along with their responsibility to reach agreement with others about what is correct. I say this.

  13. Students of English must learn not only to judge their own work, but even that they can judge it. Pirsig says this.

  14. For Monk, Collingwood’s demise has meant Ryle’s rise: unfortunately so since, for one thing, Ryle has no interest in the past.

  15. In a metaphor developed by Matthew Arnold, Collingwood and Pirsig are two of my touchstones.

  16. Thoreau is another. He affects indifference to the past, but his real views are more subtle.

  17. According to Monk, Collingwood could have been a professional violinist; Ryle had “no ear for tunes.”

  18. For Collingwood, Victoria’s memorial to Albert was hideous; for Pirsig, Victorian America was the same.

  19. Again according to Monk, some persons might mistake Collingwood for Wittgenstein.

  20. My method of gathering together ideas, as outlined above, resembles Pirsig’s method, described in Lila, of collecting ideas on index cards.

  21. Our problems are not vague, but precise.


When Donald Trump won the 2016 U.S. Presidential election, which opinion polls had said he would lose, I wrote a post here called “How To Learn about People.” I thought for example that just calling people up and asking whom they would vote for was not a great way to learn about them, even if all you wanted to know was whom they would vote for. Why should people tell you the truth?

Piety

The post below is a way to record a passage in the Euthyphro where Socrates says something true and important about mathematics.

(see below)

The passage is on a list of Platonic passages that I recently found, having written it in a notebook on May 23, 2018. The other passages are in the Republic; here they are, for the record, with some indication of why they are worth noting (translations are Shorey’s, originally from 1930 and 1935 in the old Loeb edition):

Antitheses

This is an attempt at a dialectical understanding of freedom and responsibility, punishment and forgiveness, things like that. My text is a part of the Gospel, though I attribute no special supernatural power to this. I shall refer also to the Dialogues of Plato.

The Antitheses are the six parallel teachings, delivered by Jesus of Nazareth in the Sermon on the Mount, as recounted in Chapter 5 of the Gospel According to St Matthew, starting at verse 21. I summarize:

  1. Do not kill people; do not even get angry with them.

  2. Do not commit adultery; do not even fantasize about it.

  3. In divorce, follow the established procedure; do not even divorce.

  4. Do not forswear yourself; do not even swear.

  5. Keep retribution commensurate with the crime; do not even seek retribution.

  6. Love your neighbor; love even your enemy.
