 So it's a complicated world when we start looking at the history, not written history, but geologic history. And I hope that, not that the things that I pointed out were very important from the scientific standpoint. Very exciting. All things that there are the history of geologic and written history, not only of humankind, but of all its history. And because of this I say, I hope that in the conference yesterday, using some of the geologic examples, not only of history from the time of humankind, but of all other species, if you want to follow the legend, you have to remember that learning is a continuous process. You have to follow the nature that was true, mini-true and sometimes not true at all. The SSL process of the Apprentice, this took long. I'll say that by keeping up and reading the new things that many years ago, new discoveries in that general field shows that they were really mini-true and on the basis of new data. And sometimes that they were not true at all. There was something else involved, some other factor that was not interpreted properly. And so I think just milled around the philosopher history, said this more or less in these words. And he said this when he was 76 years old. When I was young, I was a real rebel. I wanted to change things immediately. This is paraphrasing. When I was 19 years old I knew everything and my father knew nothing. By the time I was 29, I was amazed how much my father had learned in those last 10 years, at the time that he was speaking about when he was 19 to 29. And now he says, at 75 years old, now I know nothing and so it seems to be true. Education is the progressive discovery of our own dignity. And that's the way it is. Bill Durant said when he was young, he knew everything. When he was 19, he knew everything his father knew nothing. By the time he was 29, he was amazed how much he had learned. I'm talking in the same language. I should be in Spanish. Bill Durant said this when he was 19, he knew everything and my father knew nothing. But by the time he was 29, he was amazed how much he had learned in those last 10 years. And now he says, at 76 years old, now I know nothing and so it seems to be true. Education really is a very progressive discovery of our own dignity. And that's the way it is. I hope that you'll take full advantage of your stage and learn all you can. Not only here in Siano, but in the other experiments. When you're going to develop your talents, you're going to learn all you can. You're going to learn all you can. You're going to learn all you can. You're going to learn all you can. Not only here in Siano, but in the other experiments too. When you're going to develop your talents, you're going to learn all you can. One of the greatest waste dangers. The greatest human risk for the development.
