The main reason that political and religious leaders should be afraid of scientific inventions such as the air pump is that it give more power to the average person and undermines their authority. The average person, with the help of technology, can start the explore the scientific world. Johnson mentions this on page 132 when he says that by “expose[ing] as many ideas as possible to as many minds as possible, … the system will ultimately gravitate towards truth.” As they learn about science, they will start to have a greater understanding of how the world works which will lead them to question the supposed authority that both of those institutions have. As we have seen in recent centuries and in this book, the development of technology pokes holes into the stories that the church both tell and once told the average person. This push for truth has a domino effect on politics because monarchs of those days relied on the church to propagate their right to rule. The consensus for monarchies was that their right to rule came from the divine and that it was bestowed upon them by god. If science starts to make the average citizens of a country question god, they will start to question why their ruler has the divine right to rule. This unrest leads to consequences by the person who developed the technologies. We see this in the book when the Church-and-King mob attacked Dr.Priestly and burned down both his house and his laboratory. Once someone’s mind is set, it is almost impossible to change. So when Priestly dissented against the king and the church, he faced the social consequences of his actions which were his exile.
