I've been thinking about this thread. Asimov and his robot oeuvre are an invitation to empathise with the complexities other non-biological morality. It's not exactly non-human as the Laws of Robotics are constructed (as algorithms, perhaps?) and programmed by humans. In a real sense Asimov has programmed the reader (using the right words and syntax- like all programming languages) to buy into the Laws of Robotics. This leads to another level of, perhaps, the phenomenonology of reading. If I push this point to the fullest (absurdist) extent no books have human characters; rather books have words that writers, more or less successfully, put together in a way that the reader then can build "human" characters. It is the engagement of the reader with the words that brings to life the words and makes them into characters. It must be possible, then, to have a full spectrum of both enjoyment and emotional connection with any collection of words. This would rely on 1. The skill of the writer. 2. Willingness of the reader to engage. 3. The skill of the reader to imagine. Just a few thoughts. Or I might be bloody bonkers.
