Princess Sophie, Electress of Hanover, (1630-1714) and Sophie Charlotte, Queen of Prussia, (1668-1705)

Although Princess Sophie and her daughter, Sophie Charlotte did not develop their own philosophies, they deserve recognition for their support and encouragement of intellectual thought; primarily through their support of Leibniz. Both women were famous for their keenness of mind and their love of philosophy. They are presented together to give an uninterupted view of their support of Leibnez.

Among the philosophers Princess Sophie was familiar with were Molanus, Van Helmont, John Toland, John Locke, and Pierre Bayle. She did not apply herself as rigorously as her sister, Princess Elizabeth to consideration of philosophical thought, garnering at least once, a gentle rebuke from Leibniz. She did, however, continue to question Leibniz about his theory of monads and often would send his letters on to influential relatives which assured him an international reputation. Her own philosophical belief was that of a calm acceptance of change. She wrote, at age 82, "I believe that I remain so long in this world because I keep my spirit calm."

Sophie Charlotte also maintained a friendship through letters to and support of Leibniz. She joined her mother in a keen interest in the thoughts of Toland, Locke and Bayle. However, she eclipsed her mother in applying her keen intellectual capabilities to abstract metaphysical topics. "Her last words were of Leibnez and Philosophy...she said: "Do not feel sorry for me, for now I am going to satisfy my curiosity about the principles of things that Leibniz has never been able to explain to me: about space, the infinite, being, and nothingness." quotes from Zedler, "The Three Princesses.
