Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.
Jacques-Yves Cousteau

I believe that in the 20th century, humanity has learned from many, many experiences. Some positive, and many negative. What misery, what destruction! The greatest number of human beings were killed in the two world wars of this century. But human nature is such that when we face a tremendous critical situation, the human mind can wake up and find some other alternative. That is a human capacity.
Tenzin Gyatso (14th Dalai Lama)

There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder (including it is true, some of the attempts to suppress them). This history is taught in schools, and some of the greatest criminals are extolled as heroes.
Karl Popper
It's too bad there isn't a 20th Century Charles Dickens to write about the terrible destruction of these 20th Century Fagins who make themselves rich while they destroy the psyche of so many.
L. Ron Hubbard
There were experiences in previous centuries which might well have challenged this unqualified optimism. But the expansion of man's power over nature proceeded at such a pace that all doubts were quieted, allowing the nineteenth century to become the “century of hope” and to express the modern mood in its most extravagant terms. History, refusing to move by the calendar, actually permitted the nineteenth century to indulge its illusions into the twentieth. Then came the deluge. Since 1914 one tragic experience has followed another, as if history had been designed to refute the vain delusions of modern man.
