please. Can you repeat again the example of the temperature with this to illustrate the difference between the subjective and objective? Okay, so just one second here. So objective facts would be, I would say, we'll go this into a little bit more detail also. So objective fact, I am defining it very sharply. So in my definition, objective fact is based on scientific methods which are observable. It has to be observable. If it is not observable, so observable by how. So then basically if you really want to be very short, you say we have five senses. If these are not sensed by your five senses, it doesn't exist. So I'll tell you, although I don't want to basically make our friend Pinker in other school on the red line, he's a cognitive psychologist at Harvard, really, so he would tell you really, everything else that you cannot sense or can observe doesn't exist. So trust is no, it doesn't exist. A trust is simply can, it's not measurable. He has a whole book called Enlightenment, 700 pages with hundreds of thousands of graphs and he is showing that with enlightenment we have basically done remarkably well because in all measures that he shows, of course he's very selective, he's showing that everything has improved like our infant mortality has improved, our war has gone down, people dying from war has gone down, people dying out of hunger has gone down
