Working on the art book for my post apocalyptic world building project I got used to accompanying the introduction of each character or topic with a quote to set the mood and to emphasize how little (or much) has changed, compared to the old world (not as a catchphrase the character says).
Actually I am working on a professional scavenger who is obsessed with the "ancient" civilization he encounters on his raids every day, relics of past greatness, technological advancement and peaceful unity in a wild and merciless post apocalyptic world, dressing like (what he takes for) a classic gentleman.
After WW3 civilization went downhill, people are busy surviving, cropping food, putting up defensive fortifications, fighting hostile groups of other survivors. Wandering through the remains of the old world everyday, seeing images of people making music, art, building elegant huge city scapes, this character thinks what these people are doing nowadays is not living, it's merely surviving. A human being needs education (not only about cropping and fighting, but intellectual and technical), art, musicm manners, cosmopolitanism, a groomed appearance - well, basically civilization/culture, to be able to call oneself human.
I am looking for a quote that states that one needs civilization / culture / refinement to really be(come) human or that only civilization / culture / refinement enables one to be human.
In the best case a general term like civilization or culture is used, not only focussing on one aspect, like personal virtue or art.
Note: I am only looking for real quotes, not own creative ideas to put in the mouth of some character that is said to have lived in my world.
Bonus points if the quote isn't 20th century English or ancient Roman Latin (I already use both and would like to include several cultures and eras to show the parallels throughout human history), e. g. ancient chinese philosphy, some renaissance Italian phrase about the uomo universale, the literary Age of Enlightenment or something from the British Empire (cf. gentleman), which viewed itself as extremely civilized, compared to the savage colonies it oppressed.
I have searched by myself, but that is extremely ineffective, if you only know the proposition your text should have, not an era or a writer. (And just going over all civilization quotes would take forever). So I was hoping maybe someone knows a quote, that is much easier to look up.
