Today I enjoyed tea and Talked some TOK with Kevin Hoye (IB English Literature and TOK Teacher) about 2023 TOK Essay Title 5: Are visual representations always helpful in the communication of knowledge? Discuss with reference to the human sciences and mathematics. We talked a lot about different ways into understanding this question.. 

Links to several examples discussed can be found on www.TOKTalk.org

Thank you to the random street Shanghai musician, once again for the music bringing us in and out of this track.

Visual Representations: 2023 TOK Essay Title 5

May 2024 TOK Essay Title 1: Is subjectivity overly celebrated in the arts but unfairly condemned in history? Discuss with reference to the arts and history. 

Be careful with this title: you need to really interrogate assumptions about the role of subjectivity in both arts and history. Think about instances where subjectivity may be overly celebrated in the arts and where objectivity could be of value. Likewise, think about where subjectivity is condemned and where it might also have value in history. I really like this title and look forward to hearing your thoughts on it (and reading your essays!)

Subjectivity in Arts & History: 2024 TOK Essay Title 1

I met with Jon Rees, another TOK Teacher (as well as teacher of Human Technologies and IB English) here in Hong Kong, and we discussed TOK Exhibition Prompt 23: How important are material tools in the production or acquisition of knowledge?

It was a fascinating discussion! Students, you need to be careful in this question about the difference between producing knowledge and producing things. While there is a connection (knowledge is needed to produce things), it is not an obvious connection so an exploration of the knowledge being produced (not just the thing) is required here. I think it would be very hard to argue that material tools (and conceptual tools by extension?) are not essential - and yet there’s room for exploration as you can hear from our conversation. I hope to talk with Mr. Rees again soon, as it was a very interesting and thought provoking conversation. 

Books & Resources that we referenced and discussed in relation to this talk (for links to all of these, check out www.TOKTalk.org):

‘Sapiens’ by Yuval Noah Harari - this book is essentially an exploration of the role of material tools in the development of humankind, but is especially interesting when he talks about “fictional realities”.  

‘Techno Feudalism’ by Yanis Varoufakis - he does a great job from a Marxist perspective explaining how his father taught him the concept of historical materialism, how technological development creates the tools/conditions for the advancement of the socio-cultural context. Then who controls the means of production, power/authority. 

‘How to Understand E= MC2’ by Christophe Galfard

‘The Sane Society’ by Eric Fromm - criticism of our focus on consumption in a nuclear age where we can annihilate ourselves 

‘Song of the Cell’ by Siddhartha Mukherjee - deep exploration of our understanding of biology - the first chapters are specifically focused on development of the microscope and its influence on the entire field of microbiology and beyond

‘Guns Germs Steel’ by Jared Diamond outlines the theory of geographic determinism, and thus the access to materials and the tools we can therefore make are everything in the development of humankind

‘Knowledge Illusion’ by Steven Sloman and Philip Fernbach - the illusion of explanatory depth, mistaking shared knowledge for our own

Justice with Michael Sandel 

Little Museum of the World in Chai Wan - A time machine for building peace

‘The Vanishing Face of Gaia’, by James Lovelock - essential wake-up call for humankind

‘Donut Economics’ by Kate Raworth - a hopeful perspective! Nibbling away what we need (not beyond our planetary boundaries)

How important are Material Tools?

This is one that I could discuss endlessly. Who doesn’t love imagination? I actually recorded this (and a few more episodes) nearly a year ago and have been waiting for the right time. Now seems like the right time for this one, especially as we’re talking about the role of imagination in allowing us to understand and empathize with circumstances outside of our own world.

We did go down a little LOTR rabbit hole in this one, let me know if you agree with what we said! But to bring it back to TOK, we talked about imagination in arts, literature, science, history... But we also just discussed the nature of imagining - how do we all imagine differently? Is your imagination a blank canvas? An audio box? Is it a recreation of senses in your mind? How much does it infiltrate your daily narrative? What is imagination? How is it different from reasoning or brainstorming? Are logic and imagination different versions of a similar way of thinking? Is it enough that imagination plays the role of fun and entertainment in producing knowledge about the world? Does it just make things more real and more fun?

I really enjoyed this conversation and am immensely grateful for my guests on this (and all episodes) as well as the musicians that help me to put these together. If you’re interested in joining me, please contact me via www.toktalk.org and fill out the contact form.

Finite Resources, Relentless Drive

Today’s topic is a previous TOK Essay title:  “Do good explanations have to be true?” To help me explore this question, I am joined by four fellow IB & TOK Teachers: Mr. Bill Kyzner representing Political Science, Mr. Francis Wynne, representing the Classics, including Latin Language & Greek Mythology, Mr. Jordan West-Pratt representing Natural Sciences, and today I’ll be representing the Arts.

Questions we discuss in relation to Natural Sciences, Political Science, Classics and the Arts: What does each discipline seek to explain? What might a “good” explanation look like (as opposed to a “bad” one)? Are there some explanations in your subject that are good but not necessarily true? What is the role of truth in each discipline?

Three things that stand out to me after this conversation:

1.  I was really struck by Mr. Wynne’s example of explanations in Greek Mythology that he argues are “good” and metaphorically true, but not literally true. I like this idea of different layers and kinds of truth.

2. Mr. West-Pratt’s distinction of the role of truth in Natural Science - that truth in philosophy of science being different than the practice of science… For a practicing scientist, there is no distinction between a good explanation and a true explanation - they are one and the same. Whereas philosophers of science are not necessarily truth seekers but model builders.

3. I was disturbed by the idea that truth may be irrelevant in Political Sciences. However, upon reflection, I think this is very much because of our overly liberal use of the word “truth” as a word to describe one’s understanding of reality in this discussion. I do still think there is room for further exploration of the role of truth, perhaps especially as it comes to description of facts and how this then translates into interpretations in different political lenses. Certainly, there is a danger as accepting anyone’s perspective as “subjective” truth, especially in today’s political climate.

​Finally, I still am left wondering about the relationship of truth to the goodness of an explanation, and how that might differ depending on the audience of the explanation - who is the explanation for? what is its’ purpose? and does that determine what makes it good rather than its truth quality? There’s still much to be considered here. A title like this one seems so simple, and yet so complex once we start to unpack it.

No matter if you’re a TOK student, teacher or knowledge enthusiast, I hope that our discussion got you thinking about the relationship of good explanations and truth in your areas of interest or expertise. Tune in again next time for the next episode of TOK Talk.

Thank you to the random street performer in Shanghai for the intro and outro music.
