Yes, indeed. Thanks to Barthes, Derrida, et al., we do understand literature and reading _so_ much better than anyone ever has before. Consider the following observation:
"Matters concerning speech and writing are genuinely strange; proper conversation is a mere play of words. We can only marvel at the laughable error people make--believing that they speak about things. No one knows precisely what is peculiar to language, that it concerns itself merely with itself."
Oh, wait a minute... Oops, sorry; that was written by Novalis. One of those evil Romantics. Circa 1799-1800.
Writers as diverse as Novalis and Sterne well understood the laughably over-rated "discoveries" of Post-Modernism and Post-Structuralism. Because they lived in less decadent times, however, they simply didn't pay too much attention to them, precisely because they realized how banal and trivial such observations were--and are. Of course, I don't expect that this fact will have any effect on the PoMo Bandar-Log and their echo chamber of self-congratulation, but recognizing the fact offers a start, at least.
The writer of this piece does not understand the philosophy of Nietzsche, at all (I dare say that Rand did not, either).
Nietzsche's Superhuman (Uebermensch) does not yet exist, as Nietzsche well knew. It is, for now, merely a goal for the will. When/if it ever does arise, the Superhuman will essentially belong to a different species, altogether, and it will have as much relation to "humanity" as humans have to chimpanzees. Therefore, the comment regarding the "interrelatedness of humanity" is utterly irrelevant to the idea of the Superhuman.
Also, one needn't be a Randian to find the concept of "humanity" to be utterly fictitious, a mere convenience. It is a social concept, nothing more, and many individuals exist who have minimal or even non-existent needs for other humans.
Of course, such persons are now stigmatized, though once upon a time, hermits were actually considered to be wise individuals-- which merely proves the existence of the social brainwashing to which the author of this otherwise worthwhile piece has obviously succumbed.
