Finally gave that systems theory reading a go after going through the first three chapters of Interface Fantasy for my book review and let's just say both readings have definitely warped the way I look at the world. Something tells me magic mushrooms were very strong in Luhmann's and Lacan's day...
Only a week from tackling Heidegger, I'd begun reading Nusselder's application of Lacanian psychoanalysis on interfaces, cyberspace and fantasy and found the argument that pretty much everything is a construction influenced by imagination and mediated by interfaces quite convincing.
Nek minnit, this Moeller guy's argues that everything actually is just a series of systems of communication, whether it be politics, economics or religion. It's not about who's involved, it's about what's happening, and his argument was pretty convincing as well.
So now, I'm not really sure which one to follow. There's definitely a lot of evidence to back up both world-views. Take their differing views on history for example. The consensus is that history's told differently depending on the messenger. From Nusselder's Lacanian perspective, it's because our understanding of history is shaped by subjectivity. History is made sense of by various individuals and communicate through a medium, whether it be language, TV, newspapers etc. But how we make sense of what's communicated is also affected by the world-view of the persons being communicated to.
Systems theory would focus less on the individuals in question, and believe that a person's conception of a historical event is the result of communication going on in systems such as legal systems, political systems or educational systems. In this sense, there is less emphasis on the individual's understanding and more on the structures around the individual.
Personally, I think individuality needs to be considered more so I'd lean towards the former. Systems theory seems kinda dehumanizing though it's backed up pretty well by Moeller and Luhmann. Either way, my mind is still slightly conflicted on how it should see the world.
