I like thought provoking films and last night we sat down and watched the Leonardo DiCaprio film Inception, which certainly comes into that category. The film examines the whole realm of the dream world and reality as opposed to non-reality. For the first 10 minutes or so you haven't got a clue what is going on but slowly the story unfolds and things are explained and most of it becomes clear although it cleverly leaves you hanging at the end. With good acting, very impressive sets and effects it is a fascinating film. The basic premises and some of the conclusions are complete poppycock, of course, but once you accept these, it makes for a very interesting set up. Throughout the film uses the word "subconscious" which is really a Freudian word and best avoided. We have an unconscious, there are things in our minds that we are not entirely aware. However, the idea that there is a world beneath our conscious world that somehow has a life of its own is incorrect. Ah well, good fun.
Bonhoeffer uses a similar phrase 'worldly Christianity'. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.
