At the sight of a single bone, of a single piece of bone, I recognize and reconstruct the portion of the whole from which it would have been taken. The whole being to which this fragment belonged appears in my mind's eye.
Georges CuvierRead
It is to them [fossils] alone that we owe the commencement of even a Theory of the Earth ... By them we are enabled to ascertain, with the utmost certainty, that our earth has not always been covered over by the same external crust, because we are thoroughly assured that the organized bodies to which these fossil remains belong must have lived upon the surface before they came to be buried, as they now are, at a great depth.
Interpretation
Fossils provide vital evidence for understanding the Earth's geological history and the changes it has undergone.
Georges Cuvier emphasizes the importance of fossils as crucial evidence that allows us to understand the historical changes of the Earth's surface. As these remnants of ancient life show that the Earth's crust has not remained constant, they enable scientists to reconstruct the planet's geological past and the evolution of life that existed before those organisms were fossilized.
In practice
In a classroom setting discussing paleontology, this quote can enlighten students about the significance of fossils.
At the sight of a single bone, of a single piece of bone, I recognize and reconstruct the portion of the whole from which it would have been taken. The whole being to which this fragment belonged appears in my mind's eye.
Genius and science have burst the limits of space, and few observations, explained by just reasoning, have unveiled the mechanism of the universe. Would it not also be glorious for man to burst the limits of time, and, by a few observations, to ascertain the history of this world, and the series of events which preceded the birth of the human race?
Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number - there are only methods to produce random numbers, and a strict arithmetic procedure of course is not such a method.
Dissections daily convince us of our ignorance of the seats of diseases, and cause us to blush at our prescriptions. How often are we disappointed in our expectation from the most certain and powerful of our remedies, by the negligence or obstinacy of our patients! What mischief have we done under the belief of false facts and false theories! We have assisted in multiplying diseases. We have done more — we have increased their mortality.
As life forms, viruses are just inherently interesting. It's the microworld - this universe of life too small for us to see - but it's profoundly complicated, and immensely powerful. Ebola is like a beautiful and frightening predator. There is a wonder in the operations of nature that can't be denied, even when we're the losers.
Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science. The early warnings about technological dangers also come from science.
Imagine being able to predict and prevent cancer before it starts. If we gather the world's talent and expertise in a committed, targeted effort, great progress is possible.
The observation that species are amazingly conservative and static entities throughout long periods of time has all the qualities of the emperor's new clothes: everyone knew it but preferred to ignore it. Paleontologists, faced with a recalcitrant record obstinately refusing to yield Darwin's predicted pattern, simply looked the other way.
