Время..., счастье... и знание...

"The Globe, he announced, has bought a time machine."
...
"Seeing him sitting there gave me a sinking feeling in the pit of my stomach. For I knew that in his hands rested a terrible power, a power that he was blind to or too stubborn to respect.
The power to rob every human being on Earth of every bit of happiness. For if a man could look ahead and see some of the things that no doubt were going to happen, how could he be happy?
Power to hurl the whole world into chaos. Power to make and break any man, or thing, or institution that stood before him."
