Conditional Proof is only valid if we accept the truth-functional reading of 'if'
|
10. Modality / B. Possibility / 6. Probability
|
14281
|
A thing works like formal probability if all the options sum to 100%
|

|
Conclusion improbability can't exceed summed premise improbability in valid arguments

|
Simple indicatives about past, present or future do seem to form a single semantic kind
|
|

|
Maybe forward-looking indicatives are best classed with the subjunctives
|
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
|
14275
|
Truth-function problems don't show up in mathematics
|
|
14274
|
Inferring conditionals from disjunctions or negated conjunctions gives support to truth-functionalism
|
|
14276
|
The truth-functional view makes conditionals with unlikely antecedents likely to be true
|
|

|
Doctor:'If patient still alive, change dressing'; Nurse:'Either dead patient, or change dressing'; kills patient!
|
10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
|
14271
|
Non-truth-functionalist say 'If A,B' is false if A is T and B is F, but deny that is always true for TT,FT and FF
|
|
14272
|
I say "If you touch that wire you'll get a shock"; you don't touch it. How can that make the conditional true?
|
10. Modality / B. Possibility / 8. Conditionals / e. Supposition conditionals
|
14282
|
On the supposition view, believe if A,B to the extent that A&B is nearly as likely as A
|
10. Modality / B. Possibility / 8. Conditionals / f. Pragmatics of conditionals
|
14278
|
Truth-functionalists support some conditionals which we assert, but should not actually believe
|
|

|
Does 'If A,B' say something different in each context, because of the possibiites there?
