Original English The question of who you are is a non answerable question. The question of who you are in a moment, that is an answerable question. I have a very bad habit of interrupting people when they're talking. And it can seem really rude. Let's say in a conversation, I'm experiencing great enthusiasm, and I cut somebody off. So, I'm just going to respond to what I think they're going to say. I don't wait for them to finish what they're saying. And another person experiences me as rude. Does that mean I'm rude? I think it does. I'm experiencing myself as engaged. Another person is experiencing me as rude, and that's what's real. Not because their experience is more important than mine, but because it's equally important to mine. The characteristics or traits that we think are inherent to a person are not inherent to that person. They exist to describe that person in relation to other conditions. So, if everything that exists exists in relations, then what does that mean for who you are?
### 关系实在论与边界：自我并非由个体单独决定 在许多文化中，我们都有这样一种观念，认为人是由皮肤所界定的：凡是你皮肤之内的就是你，凡是你皮肤之外的就不是你。事实上，在每一项性格测试中——你是内向者、你是外向者，你是这样的人，还是那样的人——这些都被我们假定为该人固有的特质。然而，关系实在论（relational realism）在逻辑上的必然推论是：我并不是自身身份的唯一作者，我对“我是谁”也不拥有单独的决定权。如果去问一个宽泛的问题，比如“你有多外向？”，这就预设了背景情境无关紧要；而实际上你真正应该问的是：“当你和认识的人互动、睡眠充足且置身于晚宴时，你有多外向？” 这与“当你和不认识的人在一起、睡眠充足但最近什么都没吃的时候，你有多外向？”形成了鲜明对比。因此，核心要点在于：描述你是谁的要素，是高度情境化的（situated）。作为一个人，这种说法在直觉上让我感到不对劲；但作为一名科学家，它看起来是正确的。这一观点违背了我们许多人在主观上的感知，即认为我们拥有一套无论身在何处、与谁同行都能描述我们自身的持久特质。然而，科学研究并不支持这种看法。
Original English In many cultures, we have the idea that a person is bound by the skin. What is inside your skin is you, and what is outside your skin is not you. In fact, every personality test, you're an introvert, you're an extrovert, you're this kind of person, or that kind of person, these are characteristics that we assume are inherent to the person. But, the logical implication of relational realism is that I am not the sole author of my identity, and I don't have the sole power over who I am. To ask a generic question like, "how extroverted are you?" assumes that the context doesn't matter, when really you should be asking, "well, how extroverted are you when you're interacting with people that you know, and you've had a lot of sleep, and you're at a dinner party?" versus "how extroverted are you when, you know, you're with people that you don't know, and you've had a lot of sleep and, you know, you haven't had anything to eat recently?" Right, so the point is that what describes who you are, is highly situated. As a person, that feels inherently wrong to me. But, as a scientist, it seems right. This idea violates every subjective sense that many of us have, that we have these enduring characteristics that describe us no matter where we are and who we're with. But, the science doesn't bear that out.
### 大脑预测与意义建构的生物学机制 如果我们让时间暂停，你的大脑中存在着一套模式。基于过去的统计规律，你的大脑开始为下一个时刻制定行动计划；而你的切身体验正是源自那个行动计划，这就是我们所说的**意义建构**（meaning-making）。整套过程都是以预测方式发生的，而且大部分时间都发生在你意识之外。这是我们目前对于大脑如何运作最先进的科学理解。 你所做的一切都是一种意义建构的行为。即便仅仅提出“我是谁？”这个问题并编织出一个故事，也是一种意义建构行为。意义建构的生物学机制，就是你的“感知盒”（perception box）。这意味着你并没有一个墙壁固定的感知盒；你的大脑中只有一套瞬息万变、时刻波动的信号，帮助你去理解身体内部正在发生什么，以及外部世界正在发生什么。
Original English If we stop time, your brain has a set of patterns in it. And, based on the statistics of the past, your brain begins to make an action plan for the next moment. And your lived experience results from that action plan, that is what we call meaning- making. And the whole thing is happening predictively, and most of the time outside of your awareness. That's the best scientific understanding we have right now about how your brain works. Everything you do is an act of meaning- making. Even asking the question, "Who am I?" and creating a story is an act of meaning- making. The biology of meaning- making, that is your perception box. What this means is that you don't have a perception box with fixed walls. You have a momentary, fluctuating set of signals in your brain that is helping to make sense of what's happening in your body and what's happening in the world.
### 塑造自我的主动权：审慎选择互动对象 由此得出的合乎逻辑的结论是：我们对他人身份所负有的责任，可能比我们想象的要多；而与我们产生互动的人，对我们在某一时刻是谁所产生的影响，也可能比我们所希望的要大。你在任何给定时刻想要对“你是谁”拥有更多一点掌控力，一种方法就是对你与谁互动以及你如何与他们互动承担起更加审慎的责任。记得我女儿上大学时，我对她说：去寻找那些能让你成为最好自己的那群人，找到那些能帮助你成为那个人的人。这就是我想传达的信息。
Original English The logical thing to carry away here is that we have more responsibility for the identities of other people than we might think. And, the people who we interact with have more influence over who we are in a moment than we might like. One way you can have a little more control over who you are in any given moment is by taking more deliberate responsibility over who you interact with, and how you interact with them. You know, I remember when my daughter went to college, I said to her, seek out the people who allow you to be the best version of yourself. Find the people who help you to be that person. That's the message.
