Donald Trump is not a liar; he’s a bullshitter. There is a fine difference. The philosopher Harry G. Frankfurt believed the difference between lies and bullshit is that lies are necessarily false; on the other hand, bullshit may happen to be true or false. In essence, a lie is a conscious act of deception, whereas a bullshit entails an indifference to how things really are. In order to lie, one has to implicitly acknowledge the existence of the truth — and then deceive another of not believing in such truth. However, a bullshitter does not care whether there exists a truth or a falsity. For example, I can bullshit a test by writing a bullshit answer. It doesn’t matter to me whether the answer is true or false. I just need to write some bullshit. If it happens to be true, I get a good grade. If it happens to be false, it doesn’t matter because I never bothered studying for the test to begin with.
Nietzsche believed that foregoing objective truth would be life-affirming. JL Mackie argued that disbelief in objective truth regarding morality would not be catastrophic. Some, however, worried that it could be very dangerous. If there is no objective morality, then why be moral? If there is no objective truth, then how do I make sense of things? In general, I think it is not so dangerous for people to not believe in objective truth regarding morality or the external world. We are hard-wired to care about certain values and facts; and I doubt that we would stop caring about them even if it turned out to be the case that they were not objective. I think this is especially true regarding morality. For instance, Foucault or Nietzsche still argued for certain virtues despite their skepticism of objectivity. The problem isn’t anti-realism. The problem is bullshit — antipathy towards objectivity. Trump is, in this sense, a bullshitter. He doesn’t care whether what he says is true or false. He spouts a ton of lies, but they are not calculated. They are not conscious acts of deception. It doesn’t matter to him whether his statements are true or false. A liar would try to show how his lie is the truth; Trump doesn’t provide any evidence. As we have seen, such bullshit has been extremely pernicious. Lies require effort and responsibility; one has to support them. Bullshit does not, and it can easily destroy a society when wielded by the powerful. Bullshit is worse than the nightmares of a postmodern world reigned by Nietzsche and Foucault, once feared by many. Anti-realism is not the problem; bullshit is.
