There is, perhaps, as much to be said for an acquired art and experience of “self-surveillance” as there is of the orchestrated ubiquity of surveillance in information and (communications) technology that Orwell predicted. The longer arc and trajectory of human history has been one in which the inflating internal, interior spaces of memory and perception have developed synchronously along with those of an order and rationality or linear architecture of knowledge projected outwards upon (and as) the external world. The boundaries and borders between self and world, always being in many ways indeterminate and amorphous under any extensive and pragmatic analysis, come to be replicated in and as the internal patterns and structures or experience, memory and perception.
The key takeaway is that we instinctively fear the external observer that is a necessary condition for the presence and ordered continuity of an internal one.
