8. “My dad said to me a few years ago: "There's no harm in thinking." We were talking about Crazy Uncle Albert and whether it was right to use your brain to build weapons.He said, "You can't expect people not to think. Not to know things just because they COULD be bad."I said, "Yeah, but then they built it and a hundred thousand people died."My dad laughed and said there were a lot of steps between the thinking and the doing.Which I know, duh. All I was saying is that when you think of doing something, you don't always know the consequences. For a while people THOUGHT about building the bomb, but nothing happened. In the end it was a lot of different people doing a lot of different things, most of which had nothing to do with the bomb, that did make it happen.I think about that sometimes. Who was the person who had the first thought, the one that started it all?And after they had the thought, what was the first thing they did?I know my uncle never thought, Hey, all this great science- one day I'll use it to kill a whole bunch of people.

This means we must free ourselves from all our negative traits and turn toward absolute good. No sin is unforgivable except the sin of unrepentance.” - Elder Thaddeus of Vitovnica

13. “But what is the way forward? I know what it isn't. It's not, as we once believed, plenty to eat and a home with all the modern conveniences. It's not a 2,000-mile-long wall to keep Mexicans out or more accurate weapons to kill them. It's not a better low-fat meal or a faster computer speed.

Give the people contests they win by remembering the words to more popular songs or the names of state capitals or how much corn Iowa grew last year.

An answer that will do! Because there’s food to be caught and babies to be born and life to be lived and so there is no time for big, complicated, and worrying answers!
