Question

While struggling to recover from a possibly psychosomatic illness, this philosopher challenged a correspondent to “define the passions, in order to know them better.” This philosopher wrote that a thing can only be moved by self-propulsion, external propulsion, or movement determined by the properties of something pushing it. That argument by this philosopher was the basis for a later thought experiment in which (-5[1])rifles A and B simultaneously fire (-5[1])and kill Andy and Buddy; that is Jaegwon Kim’s “pairing problem.” This dedicatee of (*) Passions of the Soul originally posed the (10[1])“interaction (10[1])argument,” (10[1])which asks how a nonextended, (-5[1])immaterial substance can act on an extended, material substance. That criticism levied by this philosopher inspired another to propose that the pineal gland was the “seat of the soul.” For 10 points, René Descartes frequently corresponded with what (10[1])Princess of Bohemia? ■END■ (10[3])

ANSWER: Princess Elisabeth of Bohemia [or Elisabeth of the Palatinate; or Elisabeth von Böhmen; or Elisabeth von der Pfalz]
