Perspective...by C.S. Lewis

Contemporaries unwittingly share many of the same assumptions. “None of us can fully escape this blindness,” says Lewis, “but we shall certainly increase it, and weaken our own guard against it, if we read only modern books.” And we can expand “books” there to include publications of all sorts: blogs, news sites, whatever.

“The only palliative is to keep the clean sea breeze of the centuries”—different contexts with different assumptions—“blowing through our minds, says Lewis, “and this can be done only by reading old books.”
