Lets assume that anne is an astronut who went on a space mission to mars five years back with her colleauge deana.but due to some caualties anne was forced to start the launch sequence leaving deana behind.<br>
<br>
<br>
five years later....<br>
<br>
anne now is in a laboratory when she suddenly started exonerating herself about the mars event.<br>
<br>
anne is crying bitterly and she is giving a kind of gesture that seem as if she was trying to reach out for something but she did'nt touch it...(lets assume that what anne is seeing bis deanas helment.)<br>
<br>
<br>
the question is this;<br>
<br>
1.If you are anne,how can you tell that you are hallucinating and that the helment you are seeing is'nt real? (this is during the hallucination,not after)<br>
<br>
<br>
2.If you are not anne,how can you tell in terms of anne the helment that seem real most/not real,between the helment of five years back and the current one you are seeing..(this also is at the time of the hallucination.)<br>
<br>
<br>
If you are not anne you can never tell in terms of anne the helment that seem real most or the unreal one...even if you are given all the details about the two helments by anne herself.you will never still know this in terms of anne....<br>
<br>
<br>
NOTE: you are not anne but you must tell this question two in terms of anne...<br>
<br>
<br>
this is an argument i have put foorward to support the dualist view of reality in the mind body problem..<br>
<br>
also note that anne is fine and she has no problem with her body chemistry that might have triggered this hallucination she is just hallucinating.
