Frankfurt makes an important distinction between lying and bullshitting. Both the liar and the bullshitter try to get away with something. But ‘lying’ is perceived to be a conscious act of deception, whereas ‘bullshitting’ is unconnected to a concern for truth. Frankfurt regards this ‘indifference to how things really are’, as the essence of bullshit. Furthermore, a lie is necessarily false, but bullshit is not – bullshit may happen to be correct or incorrect. The crux of the matter is that bullshitters hide their lack of commitment to truth. Since bullshitters ignore truth instead of acknowledging and subverting it, bullshit is a greater enemy of truth than lies.
Having established the grave danger of bullshit, Frankfurt’s next step is to ask why there is so much bullshit around. The main answer to this is that bullshit is unavoidable when people are convinced that they must have opinions about “events and conditions in all parts of the world”, about more or less anything and everything – so they speak quite extensively about things they know virtually nothing about. Frankfurt is non-committal as to whether there is more bullshit around now than before, but he maintains that there is currently a great deal.
