“All we can know is that we know nothing. And that's the height of human wisdom.”
“Nothing has been discovered, nothing has been invented. We can only know that we know nothing. And that's the highest degree of human wisdom.”
“We can know only that we know nothing. And that is the highest degree of human wisdom.”
“The only thing that we know is that we know nothing, and that is the highest flight of human wisdom.”
“We are alive. We are human, with good and bad in us. That's all we know for sure. We can't create a new species or a new world. That's been done. Now we have to live within those boundaries . What are our choices? We can despair and curse, and change nothing. We can choose evil like our enemies have done and create a world based on hate. Or we can try to make things better.”
“We're Human beings with the blood of a million savage years on our hands, but we can stop it. We can admit that we're killers, but we're not going to kill, today. That's all it takes. Knowing that we won't kill, today.”
