What Western Civilization lacks is Fear of God. It was on Rosh Hashanah at the Mir Yeshiva in NY that I read the אור ישראל [Light of Israel] by the disciple of Reb Israel Salanter [during Musaf] that made this point in such a powerful way that it has stuck with me even years later. What that means for Jewish-Christian society is simple. To get the books on Fear of God and to read them every day. There is a known set of primary works of Musar and then a secondary level. And after that a few more levels. The primary level is חובות לבבות, אורחות צדיקים, מסילת ישרים, שערי תשובה, מעלות המידות ספר הישר המיוחס לרבינו תם and a few other mediaeval books.
[I have no idea what Christians could read. I do not even know if they have an equivalent but I assume they must have.The closest thing I can think of is Aquinas.]
[Physics I should mention is also part of the mitzvah of Fear of God according to the Rambam.]
So at least on Rosh Hashanah I recommend learning as much Musar as possible.
I should mention that one reason I really liked the Mir was the small Musar session they had and after I was married and discovered Isaac Blazer's אור ישראל (Light of Israel)I spent my pare time learning Musar which I think was vey god for me.
