If I take my umbrella, then it is raining
I take my umbrella
Conclusion : It is raining
This is clearly false, since umbrellas do not cause rain. — Real Gone Cat
Another way to show that Chalmers' argument is analytic #2 is to form a new modus ponens with the converse :
If physicalism is false, then we may conceive of p-zombies
Physicalism is false
Conclusion : We may conceive of p-zombies
Clearly this could be true - if physicalism is false, then consciousness is separate from the physical, and p-zombies are easy to conceive of. But then the conceivability-of-p-zombies and physicalism-being-false form a biconditional.
So what do you say about the following :
If pigs can fly, then the moon is made of cheese
Pigs can fly
Conclusion : The moon is made of cheese
Clearly valid. But is there any truth to found? — Real Gone Cat
If I take my umbrella, then it is raining
I take my umbrella
Conclusion : It is raining — Real Gone Cat
An example of synthetic modus ponens is :
If it is raining, then I will take my umbrella
It is raining
Conclusion : I will take my umbrella
Clearly, the conclusion has no effect on the premise prior to forming the modus ponens - whether you take your umbrella before looking outside does not effect the weather outside. Thus, synthetic modus ponens adds to our knowledge of the world - it tells us something new about the conclusion. — Real Gone Cat
The question is what does 'contained in' mean? The question cannot be resolved because in Kant's time - and it was he who was so terribly insistent on the synthetic/analytic distinction - logic was not sufficiently well understood to allow a clear definition of what that means. So we cannot know how he might have attempted to define 'contained in' using the more precise modern tools.- synthetic conditional : a conditional whose consequent is not contained in its antecedent
- analytic conditional : a conditional whose consequent is contained in its antecedent — Real Gone Cat
