史蒂芬·古尔德

史蒂芬·杰伊·古尔德（英语：Stephen Jay Gould，1941年9月10日—2002年5月20日）是一名美国古生物学家、演化生物学家，科学史学家与科普作家，职业生涯中大多在哈佛大学担任教职，并曾在纽约的美国自然史博物馆工作。

生平

古尔德出生于纽约市皇后区，父亲伦纳德为法庭速记员，母亲埃利诺是个艺术家。古尔德五岁时，他父亲带他到美国自然史博物馆的恐龙厅参观，这是他最早接触到暴龙的时刻。

科学研究

古尔德早期研究的对象是百慕大地区的蜗牛。1972年，他和纽约美国自然史博物馆的尼尔斯·艾崔奇（Niles Eldredge）共同提出“间断平衡”（英语：Punctuated Equilibrium）进化理论，由此享誉全球。“间断平衡”理论认为，生物的进化并不像达尔文所认为的那样，是一个缓慢的渐变积累的过程；而是长期的稳定甚至不变与短暂的剧变交替的过程，从而解释了化石在地层中为什么会有许多空缺之处。

古尔德是一位忠实的达尔文主义者，他认为达尔文理论的核心是自然选择，而不是生存竞争或生物渐变论。从他的作品中可以看出，他非常推崇自然选择在生物进化中的作用，尤其难能可贵的是，他也承认，自然选择不是唯一答案，而是最重要的答案。

科普写作

古尔德的另一杰出贡献并不是提出什么理论，而是他写出了大量的科普作品，令世人对古生物学产生兴趣。没有人关注的科学是没有生命力的科学，古尔德的科普文章给予了古生物学持续的生命动力。古尔德文笔流畅、学识渊博，不仅向读者解释自然现象，而且讲述自然现象所引出的思考及其对人类社会的影响，他对科学的反思相当深刻，对社会曲解科学理论进行了尖锐的批判。他的主要科普作品有《千禧年》、《自达尔文以来》（台译：《达尔文大震撼》）、《熊猫的拇指》、《奇妙的生命》（台译：《壮丽的生命》）等。

Stephen Jay Gould ( GOOLD; September 10, 1941 – May 20, 2002) was an American paleontologist, evolutionary biologist, historian of science, and one of the most widely read authors of popular science of his generation. Gould spent most of his career teaching at Harvard University and working at the American Museum of Natural History in New York. In 1996, Gould was hired as the Vincent Astor Visiting Research Professor of Biology at New York University, after which he divided his time teaching between there and Harvard.

Gould's most significant contribution to his field was the theory of punctuated equilibrium developed with Niles Eldredge in 1972. The theory proposes that most evolution is characterized by long periods of evolutionary stability, infrequently punctuated by swift periods of branching speciation. The theory was contrasted against phyletic gradualism, the popular idea that evolutionary change is marked by a pattern of smooth and continuous change in the fossil record.

Most of Gould's empirical research was based on the land snail genera Poecilozonites and Cerion. He also made important contributions to evolutionary developmental biology, receiving broad professional recognition for his book Ontogeny and Phylogeny. In evolutionary theory he opposed the overemphasis placed on natural selection, and was critical of biological determinist theories of human behavior in sociobiology and evolutionary psychology. As a public advocate for science he campaigned against creationism and proposed that science and religion should be considered two distinct fields (or "non-overlapping magisteria") whose authorities do not overlap.

Gould was known by the general public mainly for his 300 popular essays in Natural History magazine, and his numerous books written for both the specialist and non-specialist.

In April 2000, the US Library of Congress named him a "Living Legend".

Biography

Stephen Jay Gould was born in Queens, New York, on September 10, 1941. His father Leonard was a court stenographer and a World War II veteran of the United States Navy. His mother Eleanor was an artist, whose parents were Jewish immigrants living and working in the city's Garment District. Gould and his younger brother Peter were raised in Bayside, a middle-class neighborhood in the northeastern section of Queens. He attended P.S. 26 elementary school and graduated from Jamaica High School.

When Gould was five years old his father took him to the Hall of Dinosaurs in the American Museum of Natural History, where he first encountered Tyrannosaurus rex. "I had no idea there were such things—I was awestruck," Gould once recalled. It was in that moment that he decided to become a paleontologist.

Raised in a secular Jewish home, Gould did not formally practice religion and preferred to be called an agnostic. When asked directly if he was an agnostic in Skeptic magazine, he responded:

If you absolutely forced me to bet on the existence of a conventional anthropomorphic deity, of course I'd bet no. But, basically, Huxley was right when he said that agnosticism is the only honorable position because we really cannot know. And that's right. I'd be real surprised if there turned out to be a conventional God.

Though he "had been brought up by a Marxist father", he stated that his father's politics were "very different" from his own. In describing his own political views, he has said they "tend to the left of center". According to Gould the most influential political books he read were C. Wright Mills's The Power Elite and the political writings of Noam Chomsky.
