IN THE age of Trump, the person writing those words has much to teach us about the impending scientific struggles of our own time.
So spoke Salviati on day two of his debate with Sagredo and Simplicio in a hypothetical discussion imagined by the great scientist and astronomer Galileo Galilei, for his book Dialogue on the Two Chief World Systems, published in 1632.
In the Dialogue, Galileo puts forward his heretical view that the Earth and other planets revolve around the sun in opposition to the Catholic Church-sanctioned Ptolemaic system in which everything in the universe revolves around the Earth.
Galileo hoped that by adopting a conversational style for his argument, it would allow him to continue his argument about the true nature of the universe and evade the attentions of the Inquisition, which enforced Church doctrine with the force of bans, imprisonment and execution.
However, Galileo's friend, Pope Urban VIII, who had personally authorized Galileo to write the Dialogue, didn't allow sentimentality to obstruct power. Galileo was convicted of heresy and spent the rest of his days under house arrest--the Dialogue was banned by the Inquisition, along with any other book Galileo had written or might write.
Typically portrayed as the quintessential clash between religion and science, Galileo's conflict with the Papacy was, in fact, just as rooted in material considerations of political power as it was with ideas about the nature of the solar system and our place within it.
Amid parallels to today's conflict between Donald Trump and the scientific community over funding, research, unimpeded freedom of speech and the kind of international collaboration required for effective scientific endeavor, neither situation exists solely in the realm of ideas.
