thought for today

Trevor Noah: Limited

“We tell people to follow their dreams, but you can only dream of what you can imagine, and, depending on where you come from, your imagination can be quite limited.”
–  Trevor Noah.

Donald Knuth: Bottom of things

“Email is a wonderful thing for people whose role in life is to be on top of things. But not for me; my role is to be on the bottom of things. What I do takes long hours of studying and uninterruptible concentration. I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don’t have time for such study.”

—Donald Knuth.

Peter Singer: Tribal ethic

“In an earlier stage of our development most human groups held to a tribal ethic. Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased. Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks. So African human beings could be captured, shipped to America, and sold. In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today. Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter, and the destruction of wilderness. We must take the final step in expanding the circle of ethics.”

— Peter Singer.

Thurgood Marshall: Dissent

“We must dissent from the fear, the hatred, and the mistrust. We must dissent from a nation that buried its head in the sand waiting in vain for the needs of its poor, its elderly, and its sick to disappear and just blow away. We must dissent from a government that has left its young without jobs, education, or hope. We must dissent from the poverty of vision and timeless absence of moral leadership. We must dissent, because America can do better, because America has no choice but to do better.”

—Thurgood Marshall.
