我们如何判断一个生物是否有感知？
最简单的判断方法之一，就是看其是否能够使用工具。特乌索斯不穿“衣服”，因此这第一条也是最简单的衡量标准并不适用。那其他形式的工具呢？这一点判断起来就有些困难了。我们看不到地球上常见的工厂、作坊或农田等景观，但只要仔细观察，就会发现一个无可辩驳的事实：这个世界，这颗星球本身，似乎是被一种蓄意的、有感知的意识所塑造的。
英文原文
How do we know if an organism is sentient?
One of the easiest things to look for is if it is capable of tool use. The Teuthos do not wear 'clothes', so the first and easiest metric is no use to us. What about other forms of tools? Here, it is a little harder to judge. We see no factories, no workshops or agricultural landscaping as we are used to on Earth - but look closer and it is irrefutable that the world, the planet itself, appears to have been shaped by a deliberate, sentient consciousness.
