库恩的范式论与科学革命美国科学史家和科学哲学家托马斯?库恩(ThomasSamualKuhn,1922-1996)于1962年提出了所谓“范式更替”的科学革命理论。

他给出了科学发展的下述模式:“前科学→常规科学(形成范式)→反常→危机→科学革命(新范式战胜旧范式)→新的常规科学→……”这一理论的核心是范式概念,在库恩看来,范式是一种对本体论、认识论和方法@的基本承诺。具体地说,范式是科学家集团所共同接受的一组假说、理论、准则和方法的总和,这些东西在心理上形成科学家的共同信念。库恩认为,范式是使一门学科成为科学的必要条件或成熟标志。也就是把范式看作科学与非科学的分界标准。任何一门学科只有具有共同的范式,才可以称为科学,否则就不能称为科学或称前科学。库恩根据范式概念提出他的科学发展模式理论。在科学发展观上,库恩既反对逻辑实证主义的科学发展的“逐渐积累”观,也反对波普的批判理性主义关于科学发展是“不断推翻的增长”的观点。他相信科学发展的实际过程是一个进化与革命、积累与飞跃、连续和中断的不断交替的过程,而且科学发展的历史明显地体现了这个过程。

科学发展一般经历四个时期:

(1)前科学时期;

(2)常规科学时期;

(3)反常和危机时期;

(4)科学革命时期,既而又发展到新的常规科学。

在科学史上,如天文学中的哥白尼革命,化学中的拉瓦锡革命,物理学中先有牛顿革命而后有爱因斯坦革命。这种科学革命的典型例子说明,新范式最终战胜并取代了旧范式,这就标志着科学革命时期的结束,而进入了新的常规科学时期。在新的常规科学时期中,新的范式成了该学科的科学共同体的共同信念。科学研究在新范式的指引下继续积累地前进,但是到了后来,又出现了许多反常现象,陷入新的科学危机,而引起新的科学革命,并实现从新的范式到更新的范式的转变,而进入更新的常规科学时期。科学发展就是通过这几个环节的不断循环往复而不断前进的。

库恩的科学发展动态模式可以简单表示为:

前科学时期→常规科学时期→反常和危机→科学革命→新的常规科学时期……库恩认为,一切科学的发展都是按照这个科学革命的规律发展的。库恩的范式论是关于科学发展的一般方法@,在它提出之后,不但引起哲学家和科学家的热烈讨论,也引起社会科学家的积极响应。社会学家、经济学家、政治学家和心理学家等都纷纷运用范式论来分析和说明各自学科的历史发展过程。1988年苛勒曼和萨勒门发表了《心理学杂志文献中的库恩的(科学革命的结构)》一文,综述了范式论在心理学中的应用情况。

下列选项中不正确的是()。

A、科学的演变和发展是与科学以外的社会和历史因素紧密联系。

B、库恩首创周期性科学发展模式,这一模式把科学发展的量变与质变、肯定与否定、进化与革命这两种对立的因素统一起来

C、库恩的范式论中的第3个时期(反常和危机时期)是科学变革的结束

D、库恩的范式论在科学哲学史上具有上承波普下启拉卡托斯的作用

The wife-carrying World Championship has been celebrated in a small town in central Finland since 1992.

The Friday after the American holiday of Thanksgiving is called Black Friday. It’s said that it’s the day that store ledgers(分类账)move into the black and companies become profitable(有利可图的,有益的). On that day, retailers(零售商)slash prices to get consumers to buy.  It is also a time when many Americans start their Christmas shopping. VOA’s Elizabeth Lee tells us how the economy may affect consumers on that bargain day.

“It’s just the deals, the sales and everything you can get for a lesser(较少的,较小的)price,” said Sandy Thomas, a shopper. But it’s a nightmare(噩梦)for others. “I think it’s crazy. I’ve done all of my shopping throughout the week so I don’t have to go out on Friday,” she said. It’s called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it’s the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look.

While the lead up to Christmas is known as the season of giving, Black Friday can get ugly.

Last year a crowd of bargain-hunters killed a Wal-mart(沃尔玛公司)worker in a New York suburb. This year, many stores are increasing security while they slash prices. “This is a huge time for the retail stores,” said Fred Joutz from George Washington University. “This is when they begin making their profits for the year.”

Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future.

With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. “Credit is still strictly controlled whether through credit cards or through borrowing from banks,” he said. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed.  Other stores open their doors anywhere from midnight to four in the morning.

And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it’s an annual family tradition and well worth it. “I just save maybe half of what I would have spent on a regular, you know, shopping trip,” she said.

Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully.     

小题1: The underlined word “slash” in the first paragraph probably means _________.

A.reduce

B.raise

C.increase

D.change小题2:The sentence “This day should be a shopper’s dream.” should be placed between ________.

A.paragraph two and paragraph three

B.paragraph one and paragraph two

C.paragraph three and paragraph four

D.paragraph five and paragraph six小题3:Why are many stores increasing security according to the passage?

A.Because there are too many people saving more and spending less.

B.Because it’s a time when they begin making their profits for the year.

C.Because last year a crowd of bargain-hunters caused an accident.

D.Because many stores open their doors from midnight to four a.m.小题4:What can we learn from the passage?

A.Christmas shopping is traditional time and this year it is no exception.

B.Electronics like flat screen TVs are usually least discounted.

C.The economy only affects consumers on that bargain day.

D.Thanksgiving is a good indication of how consumers feel about the future.
