I mean, Tristan Tzara is Romanian and so it seems likely that this thought isn't originally English anyway, so it's reasonable for a modern writer to choose to translate it in a more inclusive way. I expect that an early English Bible and a modern one likewise make different choices about whether a text that's clearly about people generally and isn't concerned with sex or gender - should say "He" or "They" / "His" or "Their" and so on.
