itself. We are parts of physical reality that talk about it from inside
physical reality itself. John von Neumann considered the possibility that “the
information available to the observer regarding his own state could have
absolute limitations, by the laws of nature” [von Neumann 2018]. It seems
plausible that any theory of physical reality that we can formulate from the
inside must be incomplete, with some irreducible indeterminacy.”</font></p><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:107%">

measurement, but I will not discuss it here. It concerns introspective systems,
where subject = object so that the basic conception of a single subject
observing an ensemble of objects must be modified."</i> -- David Finkelstein, "The Physics of Logic", in "Paradigms and Paradoxes",

responded. <i>"Weizsäcker proposed in conversation that in fact the observer
divides into two parts on such occasions, and then one observes the other as
usual. When the observer is outside the system, the measurement is represented
by a time-dependent interaction Hamiltonian. This would not make sense for
self-observation, but one can imagine a self-interaction governed by an
internal parameter instead of time."</i></span></span></font></p></div></div></div></blockquote><div><br></div><div>Thank you Serafino for sending me great relevant references!</div><div>G.</div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div><p class="MsoNormal" style="margin:0cm;font-family:"Times New Roman",serif"><i><font size="4"><span></span></font></i></p>
