静止土压力

       晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之。复前行，欲穷其林。

       林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田美池桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。

       见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”

       既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。

      南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。

We like to think our intelligence is self-made; it happens inside our heads, the product of our inner thoughts alone. But the rise of Google, Wikipedia and other online tools has made many people question the impact of these technologies on our brains. Is typing in “Who has played James Bond in the movies?” the same as our knowledge about the names like Roger Moore, Timothy Dalton, Pierce Brosnan and Daniel Craig? Can we say we know the answer as long as we know how to rapidly get the information on Google?

Here the question is about how we define intelligence itself. The answer appears to be interesting, because the evidence from psychological studies suggests that much of our intelligence comes from how we coordinate ourselves with other people and our environment.

An influential theory among psychologists is that we're cognitive misers(认知吝啬者). This is the idea that we are unwilling to do mental work unless we have to. We try to avoid thinking things fully when a short cut is available. If you've ever voted for the presidential candidate(总统候选人) with the most honest smile, or chosen a restaurant based on how many people are already sitting in there, then you are a cognitive miser. The theory explains why we'd much rather type a zip code into Google Maps than memorize and recall the location of a place – it's so much easier to do so.

Research shows that people don't tend to rely on their memories for things they can easily access. Buildings can somehow disappear from pictures we're looking at, or the people we're talking to can be changed with someone else, and often we won't notice – a phenomenon called “change blindness”. This isn't an example of human stupidity – far from it, in fact – this is an example of mental efficiency. The mind relies on the world as a better record than memory.

Philosophers have suggested that thinking is really happening in the environment as much as it is happening in our brains. The philosopher Andy Clark called humans "natural born cyborgs(电子人)", those naturally capable of absorbing and combining new tools, ideas and abilities. In Clark's view, the route to a solution is not the issue – having the right tools really does mean you know the answers, just as much as already knowing the answer.

Rather than being forced to rely on our own resources for everything, we can share our knowledge. Technology keeps track of things for us so we don't have to, while large systems of knowledge serve the needs of society as a whole. I don't know how a computer works, or how to grow vegetables, but that knowledge is out there and I can get to benefit. The internet provides even more potential to share this knowledge. Wikipedia is one of the best examples – an increasingly large database of knowledge from which everyone can benefit.

So as well as having a physical environment – like the rooms or buildings we live or work in – we also have a mental environment, which means that when I ask you where your mind is, you shouldn’t point toward the centre of your forehead. As research shows, our minds are made up just as much by the people and tools around us as they are by the brain cells inside our skull.
