English upper class avoid conversation with the inferior class in public space in the 19th centuary I read an account of it, but I cannot find evidences or similar accounts in other books or papers, could you please help me? or give me some key words that might help in searching for information online?

Can I put "majority" in front of a noun? I looked up the word "majority " in a dictionary, and it says it is a noun and usually used like "the majority of" or "a majority". But I also found example somewhere else like "majority family" or "majority people". Is it normal for native speakers to use the word in the latter circumstance?

What does "if we don't all help" mean? The sentence comes from a song called Save Yourself by Greg Holden. Here are the excerts of the song: You've got to save yourself So you can find a way to save someone else It won't make any difference if we don't all help We all need help Does it mean "all of us don't help"? Thank you!

Why use "the" here? John Locke, THE noted English philosopher of the latter part of the 17th century, was quoted to have said that rhetoric was the science of oratory , the art of speaking with propriety, elegance and force. It is the first time John Locke appears in the passage. If it is for the reason that "noted" is used to modify "philosopher", it is not the case in the following example. Patrik Wong, an assistant professor at Northwestern University, who... "At North wester University" also modifies "professor". Thank you.^_^
