What is the good of being an island, if you are not a volcanic island?

Think about how long it took for the mountains to get there and look so beautiful. Think about how long it takes for this tree over us to grow. We're so impatient. Think about it. This leaf here took forever to become that perfect leaf. We're that. We're work in progress. That's actually being alive.

Gradually the sunken land begins to rise again, and falls perhaps again, and rises again after that, more and more gently each time, till as it were the panting earth, worn out with the fierce passions of her fiery youth, has sobbed herself to sleep once more, and this new world of man is made.

Entire new continent can emerge from the ocean in the time it takes for a Web page to show up on your screen. Contrary to what you may have heard, the Internet does not operate at the speed of light; it operates at the speed of the DMV.

America, so far as her physical history is concerned, has been falsely denominated the New World.

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.

The manner in which things exist and take place, constitutes what is called the nature of things; and a careful observation of the nature of things is the sole foundation of all truth.
