Carl Sagan died in 1996, yet he still lives in the hearts of those who knew him, whether personally or as the public celebrity he became.

Now the time has come for science to move on and find a new superhero, someone who can command both the public respect that Sagan did and challenge society for the better. Although Sagan was an agnostic who championed skepticism, he did not come across as openly hostile towards all religion, as Richard Dawkins does. Such hostility, even if justified, can turn gentle souls away from science. So who can possibly succeed Carl Sagan? Who can be the champion of reason, rationality, and tolerance for all?

I will. And so can you. And you, you, you, you and you, if only you just care to be as dedicated to science and to the welfare to humanity as Sagan was. I have championed the philosophy of Honorable Skepticism as my tribute to Sagan. But the best way to honor him is not merely to keep playing his COSMOS series and talking about what he did, but to make our own contributions to science, to EXCEED Sagan’s work, to become superheros of science ourselves. We are not expected merely to blindly follow what Sagan taught, for he was by no means infallible. Because he was human as we, we can carry his vision forward, and we will do it by eliminating the concept of “sacred cows” and seeking change to improve our societies, regardless of what short-term and localized interests get stepped on. They deserve it! And we cannot afford to appease those interests anymore. Having a global and long-term perspective is what will save us, not any religion or political ideology.
