How does this apply to a specific observable phenomenon in social relations, in other words, what examples can you generate to illustrate the explanation offered?
作者可以与什么样的人（或相对的观点）辩论？或者说，此解释与其他对同一现象的解释有何不同？
Values are in fact an abstraction from capitalist reality, not an observable phenomenon, and could not possibly 'determine' price of production (which are also an abstraction albeit on a lower level).
价值实际上是资本主义现实的抽象，不是看得见的现象，并且不可能‘决定’产品的价格（虽然它只是在一个低水平上的抽象）。

As an observable social phenomenon politeness is something superficial but to account for what is perceived at the surface we should delve into the depth where different cultural values are rooted.
虽然礼貌一种看得见的社会现象，但那只是表面而已。要真正领会其实质，我们应该努力钻研它背后隐藏着的不同的文化价值（观）。
