One of the advantages of having children is that they can oblige you to watch things you wanted to watch but probably wouldn’t have been able to watch otherwise. This evening we watched Matrix Reloaded (doubtless, I’ll get to see the last in the trilogy next weekend). I am a sucker for scifi and I love the philosophical questions these sorts of films raise. Of course, all of these stories (The Truman Show is an example from another genre) borrow from René Descartes ‘evil demon’ question. This can be summed up very simply: how can we know there’s a real world out there? Supplementary questions include: how can Neo fight with sunglasses on? And how come they don’t fall off, especially when he gets hit? Heavy.
