I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.
Interpretation
Extraordinary claims deserve thorough evidence to support them.
Carl Sagan emphasizes the importance of evidence when encountering remarkable assertions. While he encourages the pursuit of extraordinary ideas and phenomena, he warns that such claims must be backed by substantial proof to be considered credible, thus highlighting a critical aspect of scientific inquiry and skepticism.

If you represent the Earth's lifetime by a single year, say from January when it was made to December, the 21st-century would be a quarter of a second in June - a tiny fraction of the year. But even in this concertinaed cosmic perspective, our century is very, very special: the first when humans can change themselves and their home planet.
With a few honorable exceptions the press of the United States is at the beck and call of the patent medicines. Not only do the newspapers modify news possibly affecting these interests, but they sometimes become their agents.
