The present volume contains the proceedings of the conference on "Prob­ ability, dynamics and causality" that took place in Luino on June 15-17, 1995. This was the third conference on topics related to the foundations of probability and statistics held in Luino, following that on "Probability, statistics and inductive logic" (1981) and that on "Statistics in science" (1988). 1 Like the previous ones, the conference brought together people working on the foundations of probability and statistics, as well as their applica­ tion to science. The meeting opened with a session on "Exchangeability" including the papers by Persi Diaconis and Susan Holmes, Eugenio Regaz­ zini and Attilio Wedlin, followed by one on "Sufficiency, frequentism and analogy", including the papers by Colin Howson, Alan Hajek and Roberto Festa. The second day of the meeting was in honour of Dick Jeffrey, on the occasion of his forthcoming 70th birthday (August 5, 1996). Dick also took part in the previous meetings and, to use a term dear to him, we consider him the guru of the Luino conferences. The papers by Maria Car­ la Ga1avotti, Sandy Zabell, Brian Skyrms, Cristina Bicchieri and Richard Jeffrey himself all belong to this section of the conference. The third day included two sessions, devoted to "Probability and quantum mechanics" and "Probability in physical science". Abner Shimony, Giancarlo Ghirar­ di, Francesco De Martini, Nino Zanghi, Domenico Costantini and Ubaldo Garibaldi gave talks in these sessions.
