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.

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?
We put water down into the earth to push up gas, then we say, 'Ooh, we're having a water crisis.' This is foolishness, and this kind of foolishness, where we try to excuse human behavior, is dangerous.
Global warming isn't a prediction. It is happening.
The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.
Yes, genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology, etc., etc. But the regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.
There are no miracles in agricultural production.
Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.
