1 | For if you were such a brain , then , provided that the scientist is successful , nothing in your experience could possibly reveal that you were ; for your experience is ex hypothesi identical with that of something which is not a brain in a vat . |
2 | Is it possible , however , that though you do not know that you are not a brain in a vat you still know many other things , perhaps more important ? |
3 | You presumably also know that if you are sitting reading , you are not a brain in a vat . |
4 | We can surely conclude that if you know that you are sitting reading , you know that you are not a brain in a vat , and hence ( by simple modus tollens ) that since you do n't know that you are not a brain in a vat ( agreed above ) you do n't know that you are sitting reading . |
5 | We can surely conclude that if you know that you are sitting reading , you know that you are not a brain in a vat , and hence ( by simple modus tollens ) that since you do n't know that you are not a brain in a vat ( agreed above ) you do n't know that you are sitting reading . |
6 | It seems therefore to show , more generally , that since you do n't know that you are not a brain in a vat you can not know any proposition p of which you know that if p were true , you would not be a brain in a vat . |
7 | In fact its grip is restricted entirely to those propositions whose truth would mean that you were not a brain in a vat . |
8 | All we need is to show that your belief that you are not a brain in a vat can not be justified since nothing in your experience can count as evidence for that proposition , and then appeal to an analogue of : which holds that if a is justified in believing that p and that p implies q , a is justified in believing that q . |
9 | Perhaps , however , we can make this claim by appeal to the initial moves of the argument that you are not justified in believing that you are not a brain in a vat . |
10 | There we claimed that if nothing in your experience could count as evidence that you were not a brain in a vat , your belief that you are not a brain in a vat can not be called justified . |
11 | There we claimed that if nothing in your experience could count as evidence that you were not a brain in a vat , your belief that you are not a brain in a vat can not be called justified . |
12 | The belief is unjustified because nothing that you can point to suggests that you are rather than are not a brain in a vat . |
13 | The conditional theory of knowledge can show that you do not know that you are not a brain in a vat . |
14 | For a necessary condition for such knowledge , 3 ( that if it were not true that you are not a brain in a vat , you would not believe that you are not a brain in a vat ) fails . |
15 | For a necessary condition for such knowledge , 3 ( that if it were not true that you are not a brain in a vat , you would not believe that you are not a brain in a vat ) fails . |
16 | We can simplify this conditional as follows : if you were a brain in a vat , you would not believe that you are not a brain in a vat . |
17 | This is false because if you were a brain in a vat ( being fed your current experiences ) , you would still believe that you are not a brain in a vat . |
18 | Therefore , if the conditional theory of knowledge is on the right lines , you do not know that you are not a brain in a vat . |
19 | First , it can reinforce our intuitions that you know that you are sitting reading etc. , that you know that if you are sitting reading etc. you are not a brain in a vat , and that you do not know that you are not a brain in a vat . |
20 | First , it can reinforce our intuitions that you know that you are sitting reading etc. , that you know that if you are sitting reading etc. you are not a brain in a vat , and that you do not know that you are not a brain in a vat . |
21 | However , you do not know that you are not a brain in a vat because it is not the case that ( 3 ) in the nearest worlds in which you are a brain in a vat you believe that you are a brain in a vat . |
22 | We already have such an example : the case where a = you , p = you are sitting reading , and q = you are not a brain in a vat . |
23 | Second , there is something right about an argument which holds , as does the argument from error , that for the very same sort of reason that you do n't know you are not a brain in a vat , you do n't know , e.g. , that The Times will be published tomorrow , nor whether you are sitting reading . |
24 | Nozick anyway could not hold that it does , because his position relies on the independent proof it provides that you do n't know you are not a brain in a vat . |
