If memory, as it occurs in agents, is necessarily not a matter of storage but of re-creation of experience, then no such agent could exist. Moreover, even if we expand this discussion to include more aspects of psychology (as Heath suggests, and I agree), it could be that NONE of those is the kind of thing that is "stored" (regardless of medium). It could be that thinking, remembering, and acting in ways characteristic of your personality are all just activities which we naturally engage in. Activities cannot be stored. They are performed. The being which has causal continuity from moment to moment, and about whom it can be said that it did all these "personality-activities" in just such a way, is a continuing identity, and a story/biography can be told coherently about this entity. If their causal continuity were ever interrupted, they would cease to exist.<br /><br />So, your robots are not agents if their "personality" is a matter of stored information. On the other hand, they could be agents in this enactive way that I'm suggesting, and then the only thing that could kill them is the cessation of causal continuity from moment to moment. But then, causal continuity of which parts? On this view, I think we'd have to say it's whatever parts do the control-panel sort of operation. In our case, that's the brain. In the robots' cases, it is probably something on the mother board. But removing the hard drive may be more like giving a person severe amnesia. The person does not cease existing. On the other hand, if you cause her control panel to cease, then she does indeed die and cease existing.Michael Gonzalezhttps://www.blogger.com/profile/05279261871735286117noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-5890016499890873662015-06-25T13:17:14.615-05:002015-06-25T13:17:14.615-05:00I guess this presupposes some sort of functionalis...I guess this presupposes some sort of functionalist, or broadly materialistic account of the mind.

(That's one reason why it isn't problematic for God to kill someone. (cf. Heb. 11:19)) But under this scenario, "resurrecting" a robot is as easy as plugging the hard drive back in.<br /><br /><br /><i>But surely agents could have evolved whose memories are stored on a convenient isolated piece of hardware, and such agents could be persons.</i><br /><br />Hm, I wonder whether this may be begging some questions about the difference between an actual memory (personality, etc.) and a representation of one.

So nobody should think a person could be reduced to a book, or in fact, any other storage device.
