There are countless forms of employment, including many in health care, that require a combination of braininess and an ability to traverse the physical world.

有无数的就业形式，包括医疗保健领域的许多形式， 需要结合头脑和穿越物质世界的能力。

Mr. Pinker contends that this braininess has moral consequences, since people who can reason abstractly can ask: " What would the world be like if everyone did this" ?

平克声称，人们才智的增长具有道德影响，因为有能力进行抽象思维的人能够发问： " 如果所有人都这么做，世界会怎样" ？

A cynic might suggest that entire academic disciplines fall into it: existing with no apparent value to the world, with academics nevertheless competing furiously for status based on their braininess.

一个愤世嫉俗的人可能会认为整个学术学科都陷入其中：对世界没有明显价值的存在，学者们仍然根据他们的聪明才智激烈地争夺地位。
