It seems that you have missed some necessary details for us to answer this so I had to look for it. Anyway, here is the answer. The given quotation above is by Herman Melville from "Bartleby the Scrivener". The benefit of using "from his youth upward" rather than "from an early age" or "always?" is that, it suggests the narrator has a strong sense of pride. Hope this helps.
it suggests of a man that has grown up overtime. I don't know what you're asking me to answer, but if I had to guess, it be more on what the quoted words mean in the passage
