“No one, either in the nineteenth century or the twentieth, has ever built a persuasive case proving that dinosaurs as a whole were more like reptilian crocodiles than warm-blooded birds. No one has done this because it can't be done.”

“Our Twentieth Century has proved to be more cruel than preceding centuries, and the first fifty years have not erased all its horrors.”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Nobel lecture (1970)
Context: Our Twentieth Century has proved to be more cruel than preceding centuries, and the first fifty years have not erased all its horrors. Our world is rent asunder by those same old cave-age emotions of greed, envy, lack of control, mutual hostility which have picked up in passing respectable pseudonyms like class struggle, racial conflict, struggle of the masses, trade-union disputes. The primeval refusal to accept a compromise has been turned into a theoretical principle and is considered the virtue of orthodoxy. It demands millions of sacrifices in ceaseless civil wars, it drums into our souls that there is no such thing as unchanging, universal concepts of goodness and justice, that they are all fluctuating and inconstant. Therefore the rule — always do what's most profitable to your party. Any professional group no sooner sees a convenient opportunity to BREAK OFF A PIECE, even if it be unearned, even if it be superfluous, than it breaks it off there and then and no matter if the whole of society comes tumbling down.

“… if you saw a baby tyrannosaur you would probably think it was a weird looking bird. A full grown one might have had feathers too, maybe not on its whole body though, maybe more of an ornamental display sort of feathers. So traits in the theropod dinosaurs were more birdlike than say, crocodiles.”

Mark Norell (1957) American paleontologist

“Really the best way to understand anything about dinosaurs is by looking at living animals. You look at birds and then look at the closest living ancestor of birds, which is the crocodile. If you look at characteristics that birds and crocodiles have in common, the explanation is that the trait was in the common ancestor that birds and crocodiles had at one time.”

“Of course we all know that the human race has historically done better during warm periods. While we've seen a slight warming in the last century, we've also seen a worldwide improvement in the human condition. Warm – what's not to like?”
