Week 10 – Hard choices
Plan for today
- A lot in this paper
- Too much?
- Just going to focus in on her reasons for rejecting other views
Task 1, the apple pie
- The apple pie example
- A case where (as she says) we have all the information, but we cannot choose either way
- Come up with a criticism of this example
- Hint: She does point out which moments she thinks are more controversial
- Hint in a different direction: is her description of the question you're asking when you have to pick a desert the correct one?
- Is her reason bad?
- Would this get in the way of her argumentation?
- Hint: If we think better or worse tasting are commensurable, could we reject a premise of the small improvement argument?
- Needn't be clever
Interlude
- Help me out!
- What job does this discussion of practical certainty on p5 do?
- Cardinality vs ordinality
Task 2, affirming the consquent?
- At the end of section 2, it reads to me like she is affirming the consquent.
Can you see it and explain it?
\((P \rightarrow Q)\vdash(Q \rightarrow P)\)
- 'If A implies B, then B implies A' -
- 'If I see Abigail then I'm happy, then if I am happy, I must have seen Abigail' - Falascious reasoning, I could have seen an ethernet cable
- Hint: the actual version here is \(\lnot(P \rightarrow Q)\vdash\lnot(Q \rightarrow P)\)
- Any responses to defend chang?
- Are we missing something?
Interlude
Rationality
- What is acting 'rationally'
- The possibility of rationally picking randomness
- Having no reason to pick randomness
- A difficult spot in this paper
- How do we feel about the weight put on 'rationality'?
- Distinction between rationality and arrationality
Other stuff
- The term 'Qua'
- 'as a'
Task 3, incomparibility
- Come up with more criticisms!
- Collapsing the dichotomy
- Arational vs rational but random
