I interviewed Carl Sagan about three years before his death in 1996. The astronomer was charming, patient, friendly and one of the most articulate men I had ever met. He seemed to relish the act of thinking. Questions prompted thought, not prerecorded soundbites. I was prepared to find him a media-created mannequin. Instead, he was smart and attentive, not merely the star of Cosmos. Our interview soon turned into a conversation. George Santayana characterized sensibilities like Sagan’s in Realms of Being (1942): “A mind that would keep up with the truth must therefore be as nimble as the flux of existence. It must be a newspaper mind.”
The line I remember most
vividly from Cosmos has turned into a popular meme: “If you wish to make
an apple pie from scratch, you must first invent the universe.” In short, nothing
is original in the human realm. Every invention is based on the inventiveness
of our forebears. Combining and fine-tuning previous accomplishments and
insights might constitute originality. Otherwise, creation is recycling.
On July 28, 1763, Johnson dined with Boswell
at the Turk’s Head coffee-house. The conversation begins with Johnson’s criticisms
of Swift and Sheridan, writers for whom he had little sympathy. As Boswell
puts it, “the conversation then took a philosophical turn” and he reports Johnson
saying:
"Human experience,
which is constantly contradicting theory, is the great test of truth. A system,
built upon the discoveries of a great many minds, is always of more strength,
than what is produced by the mere workings of any one mind, which, of itself,
can do very little. There is not so poor a book in the world that would not be
a prodigious effort were it wrought out entirely by a single mind, without the
aid of prior investigators.”
Johnson isn’t disparaging
writers and other creators. He is urging humility and a recognition of our ever-present
precursors.
