The prolific German Jesuit philosopher and theologian Karl Rahner (1904-1984) was one of the most important Roman Catholic theologians in the twentieth century. However, here I focus on his 1941 philosophical book Hearer of the Word: Laying the Foundation for a Philosophy of Religion (New York: Continuum Publishing, 1994). More specifically, here I discuss Andrew Tallon's helpful "Editor's Introduction" (pp. ix-xxii).
