When Galileo’s old pupil feels let down near the end of the play and exclaims angrily “Unhappy the land that has no heroes”. Galileo replies humbly “No. Unhappy the land that is in need of heroes”. Our scientist is an anti-hero not just for dramatic reasons or historical accuracy, but because Brecht wants to argue for collective rather than individual agency when it comes to understanding our world and working out how to make it better. The rallying cry of this play is to build a science and technology for the people, by the people, not simply defer to experts.
