What can a forgotten chapter from the 18th century teach us about the nature of truth in science?

Émilie du Châtelet was one of the most influential philosophers of the 18th century—yet her name was nearly forgotten. Her works, translated during her lifetime, reflect her international impact on science and philosophy. Especially her insights on the role of hypotheses in research remained influential well into the 20th century. In their essay, Ruth Edith Hagengruber and Floris Velema show that du Châtelet’s achievements can be discussed in a classroom setting by interpreting her chapter “On Hypotheses“.

Abstract:

The philosopher Émilie du Châtelet (1706-1749) was one of the most successful authors of her time in the fields of philosophy and science. Her texts were translated into several languages during her lifetime, which demonstrates the international appeal of her work. Many aspects contribute to her reputation as one of the most outstanding and famous philosophers of the 18^th century. Among them is her emphasis on hypotheses as the basis of scientific research. The ideas she developed had an impact well into the 20^th century, although her name had been forgotten. Her achievements can be discussed in a classroom setting by interpreting the chapter On Hypotheses, taken from her main work, the Foundations of Physics. The material has lost none of its significance and can, therefore, be a meaningful contribution to explaining the great ideas of the history of philosophy and addressing fundamental questions such as the discernment of what is true and false.
