I actually really liked this. At first it's just fun how seriously it takes the subject, but the analysis itself is surprisingly deep and interesting. It's more than just finding a more discrete definition of the word, it also expands into it's cultural significance and it's relative values as compared to lying. It's explantation of the intent of bullshit, the reasons for it, who uses it and why we seem to generally accept it a certain level, I think says a lot about the cultural context in which the bullshit takes place and is allowed to take place. It's weird that the dumb little profanity of 'bullshit', and this strange little booklet dedicated to it, could explain so much of what makes me feel uncomfortable about the world at a large scale.
It also has a surprise twist ending that totally caught me off guard. It carries all the momentum its built up against bullshit and at the very last second diverts it all against the idea of sincerity. The general conclusion about bullshit is that it is made with disregard for truth and reality (whereas lying is in opposition to truth) and is made solely to give some desired impression of the bullshitter. It then says that when confronted with the difficulty of maintaining an objective understanding of truth and reality, instead of trying to discover the reality, we remain "true to [ourselves]". But since we as individuals are fluid and changing and even harder still to know and understand, that holding to ourselves in this way is in itself a disregard for an objective truth and thus a form of bullshit.
I admit that my initial reaction to this assertion was negative, but as is typically the case with writing these reports, the act of thinking about things more deliberately has moved my feelings about it. I think the issue is just the use of the word sincerity. I understand better what is being said, and I may even agree, but I don't think sincerity means, at least not to me, what is being described here. Or maybe sincerity is too large a word which both of our understandings is true. For me sincerity is the opposite of affectation, meaning that the impression given matches exactly the intent, whereas with affectation the intent is to give an impression. Using these meanings, sincerity stands in opposition to bullshit, with affectation being almost a synonym for it. I can't imagine how someone could sincerely bullshit, as the two very ideas are so opposed, so I can't agree with the closing statement that "sincerity itself is bullshit". I agree with the sentiment presented, but not with it's misappropriation to the virtue of sincerity.
