Friday afternoon I stumbled across an interesting tidbit – that is, this weekend is Carl Sagan Day – marked by the his birthday (November 9) – thus, this unplanned post.
We can put many tags on Dr. Sagan – take your pick – scientist, astronomer, author, philosopher, cosmologist, astrophysicist, professor, television personality, and others. To me, and no matter the role, there are two facts that stand above others: he was a tireless promoter of science, plus he stood in awe of universe.
The article that sparked this post was this small collection of his inspirational quotes. To celebrate this day, I’ve taken two of the quotes from the article, plus two others, and then supported them in my style of adding videos … or maybe I simply needed an excuse to display one of my all-time favorites.
Enjoy … which was your favorite? Do you know my favorite?
I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label. But is that all? Is there nothing in here but molecules? Some people find this idea somehow demeaning to human dignity. For myself, I find it elevating that our universe permits the evolution of molecular machines as intricate and subtle as we.
What distinguishes our species is thought. The cerebral cortex is in a way a liberation. We need no longer be trapped in the genetically inherited behavior patterns of lizards and baboons: territoriality and aggression and dominance hierarchies. We are each of us largely responsible for what gets put in to our brains. For what as adults we wind up caring for and knowing about. No longer at the mercy of the reptile brain, we can change ourselves. Think of the possibilities.
A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being?
Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
