Significance of Memory in a knowers perspective.

This post is in relation to the film we've watched recently in TOK, Chris Nolan's 'Memento'. The Film is about a man, Leonard, who is on a pursuit for revenge after an incident involving the 'death' of his wife. The twist being that Leonard suffers from short term memory loss, to combat his problem he uses photographs and tattoos to 'remember' important things. A problem arises in that everything that Leonard thinks he knows is derived from theses photographs/tattoos. It comes to light at the end of the film that Leonard has already caught and killed the man that harmed his wife. He in fact started this false case of his by using these memory tools. This raises the question of how important memory is a knowers perspective. As it turns out it is extremely important. Due to the fact that these false memories had been created Leonard ended up killing innocent people. These photographs and tattoos also show us how memory can be distorted over time (although on a short scale here). Leonard is certain he knows what he knows, it is true he does know these things. However these things he knows are not true. This shows us that memory is a key factor in determining the truth behind knowledge. One persons memory of the same event could be very different to the memory of someone else. This depends on their own perspectives and their way of knowing. Leonard's way of knowing was through the pictures, others may use different methods. The beauty of it was though that Leonard had the ability to change what he knew without even remembering he had done so, meaning he could keep himself happy by continuing his already completed quest.
