Alexander Solzhenitsyn was a man from the East. Not in the sense of being from Asian culture, but in the sense of being someone formed by Russian culture and spirituality, someone who could look at the West as something of an outsider and tell us what we had let go of to the danger of our souls.
When Solzhenitsyn first came to America, he was hailed by liberals and conservatives, but many people, both left and right, quickly turned against him as he began outlining the failures of the West. Much of what he said still resonates painfully today.
An example of this is his Nobel Prize speech of 1970.
