creationism<br />

explained these observations by appealing to epicycles, which<br />

are smaller revolutions within the larger revolution <strong>of</strong> the<br />

planets around the Earth. Copernicus realized that the calculations<br />

were much simpler if one assumed that the planets were<br />

circling the Sun, not the Earth. (Interestingly, Copernicus also<br />

had to appeal to epicycles, since he assumed planetary motions<br />

were circular. Physicist and astronomer Sir Isaac Newton was<br />

later to demonstrate that planetary orbits were elliptical.)<br />

Copernicus feared that such a view might be considered<br />

heretical. When he published his views in 1514, it was<br />

in a handwritten treatise (Little Commentary) circulated only<br />

among his friends. He stated basic axioms which became the<br />

basis <strong>of</strong> his major book, De Revolutionibus Orbium Coelestium<br />

(On the revolutions <strong>of</strong> the heavenly orbs), which he<br />

began writing the following year. Among the axioms were<br />

that the Earth is not the center <strong>of</strong> the universe; the distance<br />

from the Earth to the Sun is miniscule compared with its distance<br />

to the stars; the rotation <strong>of</strong> the Earth accounts for the<br />

apparent movement <strong>of</strong> stars across the sky each night; the revolution<br />

<strong>of</strong> the Earth accounts for the apparent movements <strong>of</strong><br />

the Sun and stars over the course <strong>of</strong> a year; and the apparent<br />

backward motion <strong>of</strong> the planets was caused by the movement<br />

<strong>of</strong> the observer, on the Earth. All <strong>of</strong> these things are understood<br />

by educated people today, but in Copernicus’s time the<br />

very concept that “the Earth moves” was revolutionary.<br />

Copernicus’s progress on his book was slow, partly<br />

because he hesitated to announce his theories, and partly<br />

because he spent a lot <strong>of</strong> time as a government administrator,<br />

attempting to prevent war between Poland and the Germans<br />

and then dealing with the consequences <strong>of</strong> war. The book was<br />

not published until immediately before his death. Copernicus<br />

left his manuscript with a Lutheran theologian, who without<br />

the author’s knowledge removed the preface and substituted his<br />

own, in which he claimed the work was not intended as literal<br />

truth but just as a simpler way <strong>of</strong> doing astronomical calculations.<br />

Although many scholars were and are appalled at this<br />

substitution, it may have prevented Copernicus’s work from<br />

being condemned outright. Had Copernicus lived to see what<br />

happened to other astronomers such as Galileo Galilei, who<br />

defended the view that the Earth moved around the Sun, he<br />

might have been even more hesitant about publishing his work.<br />

Copernicus’s revelation that the Earth revolved around<br />

the Sun is considered by many historians to be the decisive<br />

work that broke the unscientific medieval view <strong>of</strong> the world<br />

and opened the way for scientific research. Copernicus’s<br />

dedication to observation over theology made all subsequent<br />

scientific work, including the development <strong>of</strong> evolutionary<br />

science, possible. He died on May 24, 1543.<br />

creationism Creationism is the belief that evolutionary science<br />

is wrong and that the history <strong>of</strong> the Earth and life can<br />

be explained only by numerous miracles. There is a range <strong>of</strong><br />

beliefs ranging from the most extreme forms <strong>of</strong> creationism<br />

to evolutionary science:<br />

• Young-Earth creationists insist that the universe and all its<br />

components were created recently by God and the entire<br />

fossil record was produced by a single flood, the Deluge <strong>of</strong><br />

Noah.<br />

• Old-Earth creationists believe that the Earth is old but that<br />

life-forms were created miraculously throughout the history<br />

<strong>of</strong> the Earth.<br />

• Theistic evolutionists accept the general outline <strong>of</strong> the<br />

evolutionary history <strong>of</strong> life on Earth but believe that God<br />

intervened miraculously, perhaps subtly, in the evolutionary<br />

process.<br />

• Deists believe that God set the natural laws in motion at<br />

the beginning and has not physically acted upon the universe<br />

since that time. Deism, in terms <strong>of</strong> scientific evidence,<br />

cannot be distinguished from evolutionary science, except<br />

perhaps in cosmology (see universe, origin <strong>of</strong>).<br />

In the review that follows, the young-Earth definition is<br />

used. Creationism consists <strong>of</strong> a creationist theology, in which<br />

the Christian Bible is interpreted literalistically, and “creation<br />

science,” in which scientific information is presented to support<br />

those literalistic Bible interpretations.<br />

Although many evolutionary scientists believe in God<br />

(see essay, “Can an <strong>Evolution</strong>ary Scientist Be Religious?”),<br />

evolutionary science operates under the assumption that God,<br />

if God exists, has not influenced the processes that are being<br />

studied.<br />

The fundamental assumption <strong>of</strong> creationists is that creationism<br />

is the only alternative to a completely nontheistic<br />

evolutionary philosophy; most consider creationism to be<br />

the only alternative to atheism. For this reason, creationists<br />

spend a great deal <strong>of</strong> time attacking aspects, sometimes<br />

even details, <strong>of</strong> evolutionary science. They imply, but seldom<br />

directly state, that if evolutionary science has even one flaw,<br />

then any reasonable person must accept all <strong>of</strong> the tenets <strong>of</strong><br />

biblical literalism, from the six days <strong>of</strong> Genesis to the Flood<br />

<strong>of</strong> Noah. Most religious people, not only in mainstream but<br />

also in conservative Christian churches, accept at least some<br />

aspects <strong>of</strong> evolutionary science and have done so for more<br />

than a century (see “American Scientific Affiliation” and the<br />

book by Matsumura in Further <strong>Reading</strong>). Many prominent<br />

evolutionists have been religious (see Gray, Asa; Teilhard<br />

de Chardin, Pierre; Dobzhansky, Theodosius). Despite<br />

this, creationists attempt to increase their support base by<br />

presenting themselves as the only alternative to atheism.<br />

There is a limited amount <strong>of</strong> diversity in creationist<br />

beliefs. For example, many creationists do not believe that<br />

God created each species, as defined by modern science, separately;<br />

they believe instead that God created separate “kinds,”<br />

an undefined category that may refer to species, genus, family,<br />

or other level <strong>of</strong> taxonomic classification (see Linnaean<br />

system). Creationists have even invented a new taxonomic
