Harry Frankfurt an American philosopher and author of On Bullshit, talks about what bullshit is and how dangerous it is to society.
The reason why there’s so much bullshit I think is that people just talk. If they don’t talk, they don’t get paid. The advertiser wants to gain sales. The politician wants to gain votes. Now, that’s ok but they have to talk about things that they don’t really know much about. So, since they don’t have anything really valid to say, they just say whatever they think will interest the audience, make it appear they know what they’re talking about. And what comes out is bullshit.
The bullshitter is more creative. He’s not submissive. It’s not important to him what the world really is like. What’s important to him is how he’d like to represent himself. He takes a more adventurous and inventive attitude towards reality, which may be sometimes very colorful, sometimes amusing, sometimes it might produce results that are enjoyable. But it’s also very dangerous.
Liars attempt to conceal the truth by substituting something for the truth that isn’t true. Bullshit is not a matter of trying to conceal the truth, it is a matter of trying to manipulate the listener, and if the truth will do, then that’s fine and if the truth won’t do, that’s also fine. The bullshitter is indifferent to the truth in a way in which the liar is not. He’s playing a different game.
