The Objections and Replies format of the Meditations · 1641
The author solicited objections himself and published them in the same volume as the text. What this argued against was treating a work of philosophy as a monologue; the cost is that the Replies are often written more tightly than the Meditations, so a reader who takes only the main text misses the author's own answer to his strongest opposition.
Foundational
Popper · mid twentieth century · falsifiability as a demarcation
Holds that a theory's weight lies in what it forbids. This course borrows it for bookkeeping, not for selection — applied strictly it would rule out most interpretive work, which is not the purpose here.
Turn
Chapters 1 to 6 of this course
The object of this audit. Block 3 (derivation) and block 5 (cracks) of each chapter are the entry points; what matters is whether that chapter's one textual claim stands.

机制02
What definition in disguise looks like in philosophy
Chapter 3's 'I think, so I am', chapter 5's 'error comes from overstepping' and chapter 6's 'the supremely perfect contains existence' all come out of one shape, and this course gives it a name: definition in disguise. The reason for flagging it is practical: all three come out of 'I', 'the difference between ranges' and 'supremely perfect', three formulations supplied by the author himself, and all three happen to be among the most quoted sentences in the book. Left unflagged, a reader carries the certainty of the earlier steps over onto the sentence.
机制A proposition true by definition, through being presented as a discovery, lends the definition's certainty to the conclusion.
可迁移性测试
Move it to a contract: put a right into the definitions clause, then say in the body 'under this contract party B enjoys that right', and it reads as though the body granted it. The isomorphism breaks in that a contract lists definitions up front where a reader can check back, while philosophical definitions are scattered through the argument.
机制03
The strongest opposition, bound in
This book has a convenience rare in philosophy: the author bound the strongest objections and his own answers into the same volume. Every debate block in the first six chapters lands somewhere findable in the Objections and Replies — Hobbes on substantialising, Arnauld on the circle, Gassendi on perfection and the causal principle. This course books it as a ready-made list of opponents: reading this book you need not construct the opposition yourself — when a step looks suspect, go to the Replies and find the matching item.
机制Objections published in the same volume, through supplying the strongest opposition ready-made, spare the reader from constructing it.
可迁移性测试
Move it to a design review: send the review comments and the author's answers out attached to the proposal, and readers see at once where the sharpest doubts are. The isomorphism breaks in that review comments are usually internal, while these objections were solicited and published by the author, so the selection bias is smaller.
Derivation04
Counting the categories in chapters 1 to 6
This section totals the category of every derivation step in the first six chapters, and reaches one conclusion: the course's textual risk is concentrated in six propositions, all of which have a matching opponent in the Replies.
Chapters 1 to 6 have 4 derivation steps each, 24 in all
Counting convention: only the steps inside block 3 of each chapter, not the cracks or debate blocks.
12 steps are tagged [identity] and 6 are tagged [assumption]
Definition unpacked carries no textual risk; an assumption is a premise the author chose, and removing it breaks the argument.
6 steps are tagged [textual], exactly one per chapter
In an interpretive discipline this is the only class that can be refuted by the original.

本书主张
This course's position: reading a work of philosophy, the only things worth checking repeatedly are the steps presented as discoveries that in fact follow from the author's definitions, and the step attributing a claim to the author.
另一种看法
Another line holds that treating a philosophical text as an argument to be checked step by step is a misreading: the value of a work like the Meditations lies in walking the reader through a movement of thought, and dismantling it sentence by sentence turns it into a heap of dry propositions and loses what it actually gives.
分歧扎在
The disagreement is rooted in what you mean to take away from the book. If it is the experience of a movement of thought, dismantling is a loss; if it is a structure to carry elsewhere, not dismantling means carrying nothing. This course wants the second and so takes the first position — a choice determined by the goal, not a refutation of the other reading.
什么证据能裁决
What would settle it is transferable output after reading: have two groups read dismantling-style and immersion-style, then ask each to point out where definition in disguise sits in a new argument. If the first group is markedly more accurate, this course's position holds on its own terms.
No such comparison exists, so this course's position counts only as an untested methodological choice. What is missing is a design that separates the reading style from the readers' prior training — people willing to read dismantling-style may already be better at this.
Textual test07
The 'strongest opposition, bound in' reading as a testable specification
The reading under test: the points of dispute of all 6 textual claims in chapters 1 to 6 are findable in the objections and replies published in the same volume.
Edition: the Latin first edition of 1641 including all six sets of Objections and Replies, with a standard translation alongside
Fixed in advance; the Seventh Objections came after the first edition and are excluded from this test.
Decisive passages: step 4 of block 3 in each of chapters 1 to 6, against every item in the six sets
Specified in advance and matched one by one.
What counts as a match: an objection challenges the same step and Descartes answers it in the Replies
A challenge with no answer counts as a partial match and is booked separately.
What the rival reading predicts: if these disputes are mainly later inventions, several should have no match in the six sets
The two readings differ observably on how many matches are found.
Pre-registered failure condition: fewer than 4 of the 6 have a complete match
The threshold is fixed in advance and may not be adjusted after the check.

Which slot it hangs on
挂在哪个槽位The conclusion you already hold is probably 'reading a classic means understanding the author's line of thought' — a judgement about the goal of reading. This chapter goes at its operable part.
Does this chapter (a) replace 'understand the author's line of thought', or (b) constrain it: understanding is cashed out as being able to point to which step follows from a definition?
慢变量Register two slow variables: how many places of definition in disguise you can point to, and how often you turn back to check a definition while reading a book. Look at the second first.
小结09
本章小结
01Of the 24 derivation steps in chapters 1 to 6, 12 are definition unpacked and 6 are assumptions; only 6 textual claims carry risk.
02Definition in disguise appears three times in this book, each presenting something owed to the author's definition as a discovery.
03The objections published in the same volume supply ready-made opposition, which makes item-by-item checking possible.
04'Not broken into steps here' and 'sleight of hand here' must be booked separately; a difference of genre is not a defect.
05This course's choice of a dismantling reading is determined by its goal, not a refutation of immersive reading.
