在无尽的无知面前，人人平等We’re All Equal in Our Infinite Ignorance
布雷特：归纳法认为，预测是科学存在的主要原因；但实际上，科学真正关乎的是解释。
你想要的是对当下所发生之事的解释，哪怕你不一定能确切预测接下来会发生什么。
事实上，对接下来要发生的事有一定把握，反而可能令人泄气。比起确信明天会带来什么，未知要有趣得多。
纳瓦尔：这引出了相关的另一点：科学从未定论。我们应该始终保有新的创造力和新的猜想。
你永远不知道最好的想法会从哪里冒出来。凡是真诚提出的想法，你都应该认真对待。
所谓"科学已定论"或"科学已封顶"的说法纯属无稽之谈。它暗示我们可以就提出新理论的流程达成一致。
但新理论来自创造与猜想。大门永远敞开，欢迎带着新想法的新人进来做这件事。
布雷特：正如波普尔所说："在无限的无知面前，我们人人平等。"
即使某人声称自己是专家——而且这种声称或许成立——也仍有数不清的事情是他不知道的，而这些未知可能会影响他所知的一切。
一个什么都不精的学生，照样可能提出一个想法，动摇最伟大专家的根基。
就像孩子一样，专家对很多事情也一无所知，也可能出错。缺乏那套精细知识的人，照样能指出这些错误，并提出更好的想法。
Brett: Induction says that prediction is the main reason science exists, but it’s really explanation.
You want an explanation of what’s going on, even if you can’t necessarily predict with any certainty what’s going to happen next.
In fact, knowing what’s going to happen next with some degree of certainty can be deflating. The unknown can be far more fun than absolute certitude about what tomorrow will bring.
Naval: This brings us to the related point that science is never settled. We should always be free to have new creativity and new conjecture.
You never know where the best ideas are going to come from. You have to take every idea that’s made in good faith seriously.
This idea that “the science is settled” or “the science is closed” is nonsense. It implies that we can all agree on the process with which we come up with new theories.
But new theories come through creativity and conjecture. The door is always open for new people with new ideas to come in and do that.
Brett: As Popper said, “In our infinite ignorance we are all equal.”
Even if someone claims expertise—and they might have a valid claim—there’s an infinite number of things they don’t know that could affect the things they do know.
The student who’s not expert in anything can still come up with an idea that can challenge the foundations of the greatest expert.
Like the child, the expert is ignorant about a whole bunch of things and could have errors. Someone who lacks that fine-tuned knowledge can still point out those errors and present a better idea.
