Carl Sagan and My Incalculable Debt

I’ve always admired Carl Sagan, taken from us so early at age 62.

Renowned for his contributions to space exploration and the search for extraterrestrial life, his thirteen year running public TV series, Cosmos, garnered an international audience of 500 million.

A prodigious scholar, he wrote some 600 papers and twenty books.

He wasn’t a child of privilege. His family knew poverty firsthand.

Sagan taught at Harvard for five years as an assistant professor following his undergraduate and graduate studies at the University of Chicago, only to be denied tenure. They said his interests were too broad.

Cornell immediately offered him a teaching position, and he would teach there, loved by his students and esteemed by colleagues, until his death thirty years later. Following his death, Smithsonian Magazine declared him “irreplaceable.”

I liked him especially for his advocacy of skepticism and embrace of reason and scientific methodology.

There’s a biblical proverb I remember: “Let another man praise you, and not your own mouth; A stranger, and not your own lips” (Proverbs 27:2).

Sagan was never given to affectation or condescension, an anomaly among eminent professors from elite universities I’ve known across the years:

“I think I’m able to explain things because understanding wasn’t entirely easy for me. Some things that the most brilliant students were able to see instantly I had to work to understand. I can remember what I had to do to figure it out. The very brilliant ones figure it out so fast they never see the mechanics of understanding.”

Along with Voltaire, Hume, Mill, and Russell, I owe Sagan an incalculable debt in helping me find the truth of reason that has set me free from the cultural biases, of which all of us are heirs.
