There's a post at American Renaissance worth reading which briefly summarises the challenges faced by the West over the past 1500 years. In the year 1900, it is true, the West dominated the world - a fact which has helped to feed a view of the West as being historically privileged.
However, if you go back further in history you find that the West has had to fight for its survival against powerful aggressors. If you're not already aware of this history, I encourage you to read the American Renaissance piece, as well as my own posts on the Harvest of the Steppe and White Gold.
I have only one criticism of the American Renaissance piece. It ends by explaining the problems facing the West today in terms of the rise of cultural Marxism. As I've explained previously, I'm open to learning more about the influence of the academics associated with cultural Marxism, but my reading to this point doesn't support the idea that they were a key influence. Explaining Western decline in terms of cultural Marxism also has the danger of leaving the politics of right-liberals unexamined.
Let me give some examples. Traditional Australia began to be dismantled from the early 1940s and was certainly in full swing by the late 1960s. The men who did the job in the early 1940s were part of the Labour left. The radicals of the time to their left were not cultural Marxists but your everyday Marxist-Leninist Marxists. The men who finished the job in the late 1960s were Liberal Party businessmen types.
Or look at Australia's contribution to 1960s radicalism. The most famous figures contributed by Australia, such as Richard Neville and Germaine Greer, were part of the Sydney "Push" - a loosely organised libertarian group whose politics were most influenced by a Scottish philosopher called John Anderson.
And if we look at feminism we find that it was alive and kicking by the mid-1800s, a long time before cultural Marxism was supposed to have gained its influence over the left in the 1960s and 70s.
