I just landed at LAX and the flight attendant (who had a slight Latino accent, but was a native or near-native English speaker) gave the last announcement:

> 
> "As we prepare to land please have cups and other items ready to throw away, as we're going to make one last pass through the cabin *at which time*." Full stop.
> 
> 
> 

There were several such utterances during the flight which ended with "at which time," each of which was clearly meant to signify "at this time." Is this a common usage in a variety of English I'm unfamiliar with, or is it more likely to be this one speaker's quirk?

I may be wrong, but Nietzsche seems to be saying that just as the supposedly humblest of men (viz., the porter, or [a person employed to carry burdens, especially an attendant who carries travelers' baggage at a hotel or transportation station](http://www.thefreedictionary.com/porter)) wants to be seen and admired, so too does the proudest man want to be seen and admired. 

The difference between the desire of the humble man and the desire of the proud man is a matter of degree. While the humble man is satisfied in knowing at least one person sees him and admires him (for whatever reason, perhaps for the professional way in which he carries someone's baggage), the proud person, on the other hand, is satisfied only when many, many people see him and admire him. 

Moreover, he doesn't need just an admiring glance, but he needs continually the admiring and focused attention of all kinds of people, whether his peers, whether those whom he considers to be his "inferiors," or whether anyone, really. 

For the humble man, his desire is really a search for dignity. For the proud man, his desire is not for dignity, which he has in truckloads, but for the feeling of superiority. 

Whether Nietzsche's "take" on philosophers is accurate or not, all people, regardless of their station in life want to be noticed and admired for something. In other words, we all long for significance. That longing takes an ugly turn, however, when it morphs into a superiority complex, complete with delusions of grandeur! 

In Christian circles, the saying goes, "The ground is level at the cross." I like that, and I think it speaks volumes to the blatently narcissistic age in which we live.
You are pretty correct in your assumption of what this sentence means. The author is comparing the proud to porters, saying that everyone wants an admirer. Nietzsche goes a step further to say outright that philosophers are the proudest men, and that they want the universe to admire them.

Onward, to definitions. To *suppose* something is to assume it as truth. Nietzsche here is saying that philosophers (the proudest men) already assume the universe admires them. 

As for "all sides", the philosopher sees all sides around him looking on. Going back to that pride (a pretty common motif for Nietzsche), the philosopher sees himself at the center, and all sides around that center are focused on him.
