Is science a force for good in the world? Does it make our lives, not just more comfortable and efficient, but more virtuous? A number of eighteenth-century thinkers answered these questions with a resounding 'yes'. Scientific progress, they maintained, went hand-in-hand with moral and political progress. A society with naturalists and experimenters would not just be cleverer than a society without, but also more equal and more just. In this way, the new science of the seventeenth century entered political thought in the writings of Joseph Priestley, Nicolas de Condorcet, and Immanuel Kant. Yet there was no simple correlation between confidence in science and belief in (what we now think of as) progressive politics. The new science was endorsed (and condemned) by thinkers across the political spectrum. A commitment to experimental philosophy could lead to the conservatism of Edmund Burke, the radicalism of Robespierre, or the reformism of Condorcet. Science was political, but there was no consensus about whose politics it favoured.
Read the Pinker extract for one present-day view of the political significance of science. Then read one of the other two pieces, ie. either Condorcet or Rousseau. For all these thinkers, consider: how do these thinkers conceive of scientific progress? How do they conceive of moral or political progress? In their view, what is the connection between these two kinds of progress (scientific versus moral/political)?

Rousseau, Discourse on the Sciences and the Arts (1750) - read pages 1-3 and 12-23 of the pdf
Note: the literature on this topics is scattered and uneven, mainly because the topic lies in a no-mans-land between political history and the history of science. For this reason the readings below are annotated.
Daston, Lorraine, Classical Probability in the Enlightenment (Princeton, N.J: Princeton University Press, 1988) - on Condorcet's 'moral mathematics' ie. his attempts to apply probability theory to moral and political questions such as the optimal voting system.
