If you want to know who "they" are, read the German philosopher Martin Heidegger, who wrote an essays about "man" (German for "they" or better "one" in "one says"
.
According for him "they" is a way to say things without really having to fear consequences. "It was not me who said this, I just stated what
they say".
In Heidegger's so called exitentialist philosophy "the One" (or in our case the "They"
is the yet unpersonal subject of average statements, evaluations and reactions.
This is, however, the only piece of written material I can recommend if it comes to Heidegger. Morbid and Zcott might agree with me, that it is at least questionable if Heidegger can be really seen as an existentialist at all. In any case his existentialist philosophy does not have much in common with Camus or Satre.
