“A point of view can be a dangerous luxury when substituted for insight and understanding.” ― Marshall McLuhan. McLuhan made an important contribution to the study of media. He wrote a book called The Medium is the Message which is still quoted to this day. McLuhan’s work was concerned with putting knowledge, media content and technology use into social context. He showed how having only a partial view of society and taking things at face value undermines progress. You have to know what you don’t know.
