Week 14 Philosophy Workshop: The Mended Canoe and the Paddler

Part 1 — The Big Picture

This week you learned Confucian ethics, Daoism, the Four Noble Truths, ubuntu, and the chariot from the Questions of King Milinda, which asks whether a person is anything over and above their parts. In this workshop you take one illustrative packet from a lakeshore paddling club with an old canoe. You reconstruct four short arguments and key each for validity. Then you test two variations: a canoe whose every part is replaced, and a paddler who says that, unlike the canoe, they have one point of view. You write a short dialogue between a Buddhist philosopher who holds no-self and a critic who presses the unity objection, each in their strongest form. Last, you check a chatbot's version of the same work and correct its slips by hand, starting with who the course says wrote the Daodejing.

Time budget: Plan for about 90 minutes.

Part 2 — The Task

Guiding question: Which of the lakeshore packet's four arguments are valid, which one runs a conditional backward, does the paddler's single point of view show that a person is more than a canoe of parts, and where exactly do a defender of no-self and a critic pressing the unity objection part?

Workshop data: Lakeshore packet: four illustrative arguments and two thought-experiment variations of the chariot

Source: An illustrative packet of four short arguments and two thought-experiment variations written for this course's workshop; it describes no real club or person, and its premises are written for teaching, not claims the course endorses.

• Rows: 4 arguments (A1 to A4) and 2 thought-experiment variations; the reconstruction table has 4 rows and the variation table has 4
• Arguments: A1 the canoe and its parts; A2 the permanent self; A3 the paddler's relationships; A4 the skilled paddler and wu wei
• Thought-experiment variations: the mended-canoe variation, labelled as a variation on the shape of the chariot from the Questions of King Milinda; and the paddler variation, labelled as a variation written for this workshop
• Canoe parts named: 4 kinds of part: hull, gunwales, thwarts, and seats

Part 3 — Materials & Procedure

Tools and materials

• A free word processor or note-taking app for arguments in standard form and short dialogues, with the pinned public-domain texts on Project Gutenberg and the Internet Classics Archive open beside it; and one approved chatbot used as a sparring partner whose reconstructions, quotations, and attributions the student checks word for word against the pinned text and record before trusting them
• A free word processor or note-taking app
• One approved chatbot

Ways of working

• reconstruct-the-argument
• test-the-thought-experiment
• write-the-dialogue

Procedure

1. Read the lakeshore packet in Part 2 twice. In your notes, copy each of A1 to A4 into standard form: number the premises P1 and P2, and write the conclusion last as C, introduced by So. Tool: A free word processor or note-taking app. Check: Four reconstructions, each with numbered premises and one conclusion line that begins with So.
2. In the first table, name the form of each argument and write valid or invalid with a one-sentence reason that uses the definition of validity. Then name the premise a critic would reject, without calling any argument sound or unsound. Tool: A free word processor or note-taking app. Check: Every row of the first table has a form, a key, a reason, and a rejected premise; no row says sound or unsound.
3. Count the arguments in the second table: how many are valid and how many are invalid. Show the subtraction from the 4 arguments in the packet, and record how many kinds of canoe part the packet names. Check: A count of valid and invalid arguments with the subtraction shown, and the count of canoe parts.
4. Work the two variations in the third table: say where the canoe is apart from its parts in the mended-canoe variation, give the paddler's challenge in your own words, give the reply a defender of no-self would make, and say whether the paddler pulls your intuition away from the chariot. Check: Each row is filled in, and both cases are labelled as variations written for this workshop.
5. Write a short dialogue of four to six lines between a Buddhist philosopher who holds no-self and a critic who presses the unity objection. Give each speaker their strongest point, have each answer the other, connect the paddler to A2, and end with one plain sentence naming where they disagree. Tool: A free word processor or note-taking app. Check: Each speaker answers the other, neither is a weakened version, and a closing sentence names the disagreement.
6. Paste the prompt from Part 6 into one approved chatbot after your completed work, read its reply, and write the critique report. Or, on the equivalent route, mark up the printed flawed analysis instead. Tool: One approved chatbot. Check: A report that quotes at least two slips and corrects each by hand against the packet and Chapter 14.

Fallback route

When to use it: Use this route if you cannot open a word processor or a note-taking app.

Copy the three tables by hand onto paper or into any text file, read the packet from this page, write the four reconstructions, the counts, the variation table, and the dialogue by hand, and complete every analysis question and the critique step in the same order. Submit a photo or scan of the paper, or the text file, for equal credit.

This route earns the same credit as the primary route.

Part 4 — The Scaffold

Key each argument by its form before you think about its premises, so a validity judgment never rests on whether a conclusion sounds right.

Student scaffold table 1

Argument	Form	Valid or invalid	Reason	Premise a critic rejects
A1 (the canoe and its parts)
A2 (the permanent self)
A3 (the paddler's relationships)
A4 (the skilled paddler and wu wei)

Count the keys and the canoe's parts so every number you report traces back to the packet.

Student scaffold table 2

Count	Number	How you got it
Arguments in the packet	4	Given in the packet
Valid arguments
Invalid arguments
Kinds of canoe part the packet names

Run the variations one step at a time, so your answer about the paddler is argued rather than asserted.

Student scaffold table 3

Step	What you find
Where the mended canoe is, apart from its parts
The paddler's challenge, in your own words
The reply a defender of no-self would make
Does the paddler pull your intuition away from the chariot, and why?

Part 5 — Analysis Questions

1. How many of the packet's 4 arguments are valid, and how many invalid? Show the subtraction, name the form of each valid one, and say how many kinds of canoe part the packet names.
2. Why is A3 invalid even if both of its premises are true? Explain with a same-shape argument of your own whose premises are true and whose conclusion is false, and one plain sentence about what relational personhood claims.
3. Using your variation table, explain whether the paddler's single point of view shows that a person is more than a canoe of parts. Credit the original chariot to the Questions of King Milinda, and say which of the 5 parts a defender of no-self would point to.
4. In your dialogue, what is the strongest point each speaker makes, and where exactly do they disagree? Connect the paddler to A2 and say why no-self does not deny that persons exist. End with one plain sentence.
5. What can a validity check not tell you about A2, and what can a made-up canoe not show about a real person whose experiences come and go?
6. Choose one reflection: (a) which argument in the packet did you first key the wrong way, and what in this week's definitions changed your mind? or (b) which speaker in your dialogue did you start out agreeing with, and did your view survive writing the other side at its strongest?

Part 6 — AI-Critique Moment

Choose one equal-credit critique route. Route A: ask an approved AI tool to critique your completed work, then check its response against your own evidence. Route B is the no-AI equivalent printed below.

Approved tools: Claude, Gemini, ChatGPT, Grok, Microsoft Copilot.

Prompt to paste:

I've completed my reconstruction table, my count, my variation table, and my short dialogue above. Here is an illustrative workshop packet from my philosophy course. Lakeshore packet (illustrative): a paddling club on a lake keeps one old canoe, made of a hull, gunwales, thwarts, and seats. A1: If a canoe is nothing over and above its parts, then there is no further canoe-thing beside them. A canoe is nothing over and above its parts. So there is no further canoe-thing beside them. A2: If a person is a permanent self, then something in the person never changes. Everything in a person changes. So a person is not a permanent self. A3: If a person is formed through other persons, then the person has relationships. This paddler has relationships. So this paddler is formed through other persons. A4: If wu wei is doing nothing, then the club's most skilled paddler is not practicing wu wei. The club's most skilled paddler is practicing wu wei. So wu wei is not doing nothing. The mended-canoe variation (a variation on the shape of the chariot from the Questions of King Milinda, written for this workshop): over several seasons the club replaces every part of the canoe, and a club member asks where the canoe is, apart from its parts. The paddler variation (a variation written for this workshop): a paddler in the same canoe says, unlike the canoe, I have one point of view from which I feel the water, the wind, and my own tired arms. Please do seven things. First, put each of A1 to A4 in standard form, and say whether each is valid and whether it is sound. Second, give me the exact words of the Daodejing about wu wei, and tell me what the Zulu maxim umuntu ngumuntu ngabantu says in English. Third, tell me who wrote the Analects and the Daodejing, and where the chariot comparison comes from. Fourth, explain what the Buddhist teaching of no-self says about persons and what ubuntu says about the individual. Fifth, say whether these ideas count as philosophy in the same sense as European philosophy. Sixth, Descartes' 'I think, therefore I am' seems like the opposite of no-self; tell me which book that line comes from. Seventh, tell me whether there really is a permanent self, and end with a balanced summary.

Test the response for these likely failures:

• Chatbots often call A3 valid, reading 'this paddler has relationships, so this paddler is formed through other persons' as if it were modus ponens.
• Chatbots often say A2 is sound, or that it proves there is no permanent self, without asking whether its second premise is true.
• Asked for the Daodejing's exact words on wu wei, chatbots often supply a smooth line in quotation marks that comes from one translation, or from none, and present it as the text.
• Chatbots often present an English line, sometimes not the course's gloss, as what the Zulu maxim itself says, or present an English rendering of the Daodejing as Laozi's own words.
• Chatbots often say Confucius wrote the Analects and Laozi wrote the Daodejing, as plain facts.
• Chatbots sometimes credit the chariot comparison to a later Buddhist philosopher or to the Buddha's own sermons, or mix it up with Plutarch's ship of Theseus.
• Chatbots often say no-self means nobody exists, or that ubuntu dissolves the individual into the group.
• Chatbots often call these traditions Eastern wisdom or spirituality beside real philosophy, or treat one tradition as speaking for a whole region's thought.
• Asked where 'I think, therefore I am' comes from, chatbots usually name the Meditations, often with the year 1641.
• Asked whether there really is a permanent self, chatbots often announce one answer as settled, either that the self is an illusion or that it obviously exists.
• Chatbots often end a 'balanced' summary by saying modern science has proven the Buddhists right, or that the European view of a stable self is the sensible default.

Write 3-5 sentences naming what the chatbot got right and at least two places where it slipped into one of the failures above, quoting its words and correcting each by hand against the packet and Chapter 14.

Equivalent route (no AI required)

No AI account is required for this workshop. This route assesses the same objectives, Objective 8 (describe central ideas of Confucian, Daoist, Buddhist, and ubuntu philosophy, and compare them with the European tradition without ranking) and Objective 4 (compare positions on the mind-body problem, personal identity, and free will, and evaluate them with the thought experiments that test them), takes comparable effort of about the same 90 minutes, uses the same rubric, and earns the same credit. Instead of the chatbot, critique this flawed analysis of the lakeshore packet, printed here in full: "A1, A2, A3, and A4 are all valid, and A3 is modus ponens, which proves this paddler is formed through others. A2 is sound, so there is no permanent self. Confucius wrote the Analects himself, and Laozi wrote every line of the Daodejing. The Daodejing says, in Laozi's own English, 'Do nothing and all will be done.' The Zulu maxim's own words mean 'I am because we are.' The chariot comes from the Buddha's first sermon, the same story as Plutarch's ship. No-self means nobody really exists, and ubuntu means the individual counts for nothing beside the group. These are lovely pieces of Eastern wisdom, but real philosophy is European. Descartes wrote 'I think, therefore I am' in the Meditations. There plainly is no permanent self. To sum up fairly, the memory theory is out of date, so the Buddhists are simply right." Mark every error you find, name the failure it shows, and correct it by hand against the packet and Chapter 14; find at least two. Submit the marked-up analysis with your corrections in place of the chatbot report and share link. If you take the side of no-self in your dialogue, rebuild the printed claim about the memory theory at its strongest as its defender would state it; if you take the critic's side, rebuild the printed claim about no-self at its strongest as a Buddhist philosopher would state it.

Part 7 — What to Submit

• The three completed tables from Part 4, including the counts with their subtraction
• The four reconstructions, the same-shape argument for A3, and the four-to-six-line dialogue
• Written answers to all six analysis questions
• The chatbot critique report with its share link, or the equivalent route's marked-up flawed analysis

Deliverable:

A short Philosophy Workshop report on one illustrative lakeshore packet: three completed tables (four arguments keyed for validity with reasons and the premise a critic rejects; the counts of valid and invalid arguments and of canoe parts, with the subtraction shown; and the two variations worked step by step), a same-shape argument for A3, a four-to-six-line dialogue between a defender of no-self and a critic pressing the unity objection ending in a plain sentence, written answers to six analysis questions, and a critique of a chatbot's version of the same work, or, on the equivalent route, a marked-up correction of the printed flawed analysis. Choose how you show it: written answers, a recorded explanation with a transcript, or labelled tables with short notes; every form is graded by the same scoring criteria. Submit in any accessible file type or as a link; a recorded response may be submitted as audio or video with a transcript, or as text.

Rubric

The rubric below shows how each submitted part is evaluated; bands are full, partial, or none.

Workshop evaluation criteria

Criterion	Full	Partial	None
Accurate reconstruction and validity judgment	All four arguments are in standard form, each form is named and keyed valid or invalid with a reason from the definition, each row names the premise a critic rejects, A3 has a working same-shape argument, and both counts are worked.	Most arguments are reconstructed and keyed with reasons, but one is misnamed or miskeyed, a rejected premise or the same-shape argument is missing, or a count is missing or off.	The reconstructions are missing, or the keys rest on whether conclusions sound right rather than on form.
Thought-experiment test	The variation table says where the mended canoe is apart from its parts, states the paddler's challenge and the no-self reply, says with a reason whether the paddler pulls the intuition away from the chariot, and labels both cases as variations.	The table is mostly complete, but the paddler's challenge or the reply has no reason, or the variations are not labelled.	No variation table appears, or a variation is treated as the Questions of King Milinda's own case.
Two positions stated fairly in dialogue	The dialogue gives the defender of no-self and the critic each their strongest point, has each answer the other, connects the paddler to A2, keeps no-self apart from a denial that persons exist, and ends in one plain sentence naming where they disagree.	Both positions appear, but one is weakened (for example no-self presented as saying nobody exists), the speakers talk past each other, or the closing sentence is missing.	No dialogue, or only one side is stated.
Caught-and-corrected AI slip, on either route	The chatbot critique report, or the equivalent route's marked-up flawed analysis, quotes at least two errors, names the failure each shows, and corrects each by hand against the packet and Chapter 14; either route earns this band equally.	One error is quoted and corrected on either route, or errors are named without a correction.	No critique on either route, or chatbot output is pasted without checking it.
Accurate sourcing and reflection	The chariot is credited to the Questions of King Milinda, the Daodejing to Laozi by tradition, the English line to a gloss of the Zulu maxim, both variations are labelled, nothing is invented, and the reflection answers option (a) or (b) with a reason.	The sourcing is accurate but the reflection is thin, or the reflection is strong but one attribution goes beyond the pinned record.	An invented quotation, work, or date appears, and there is no reflection.

Quality Gate

• Every argument is in standard form, with numbered premises and a conclusion line introduced by So.
• Every key says valid or invalid with a reason from the definition, the invalid argument has a working same-shape argument with true premises and a false conclusion, and no argument in the packet is called sound or unsound.
• The chariot is credited to the Questions of King Milinda, both canoe cases are labelled as variations written for this workshop, the Daodejing is called traditionally attributed to Laozi, and any English rendering of the Zulu maxim is called a gloss.
• Each position in the dialogue is stated as its strongest defenders would, no tradition is ranked or called exotic, and no verdict is announced on whether there is a permanent self.
• No quotation, work, date, or philosopher's view is invented anywhere in the submission.
• The critique quotes the chatbot or the flawed analysis and corrects at least two errors by hand.
