Philippe Mottu was a Swiss diplomat, author and activist born on 9 October 1913 in Geneva; he died in Lonay (Vaud) on 23 August 2010. In 1946, inspired by the American Frank Buchman, he was instrumental in the acquisition of the former Caux Palace Hotel, a dilapidated hotel above Montreux, Switzerland, by a group of about 100 Swiss, in order to create an international conference centre at the service of European reconciliation and reconstruction. He wrote a dozen books of political and social philosophy.
Biography
Background and youth The scion of an old Geneva family whose ancestor Jacques Mottu had moved to Geneva towards 1597, Philippe Mottu is the son of the pastor Henri Mottu, moderator of the « vénérable Compagnie des Pasteurs de Genève », and of Marthe Mottu, née Reverdin. A graduate of the Political Science school of the Geneva University, he started his professional life in a bank. In 1933 he underwent a deep spiritual experience which led him to undertake theology studies in Lausanne. There, his Latin professor, Jules Rochat, put him in touch with the Oxford Group, soon to become Moral Rearmament (and currently Initiatives of Change). He was immediately won by the ideas and practice of the Oxford Group.
Moral Rearmament
In 1935, Philippe Mottu meets for the first time Frank Buchman, the Oxford Group's founder who visits Geneva with a team in order to talk to League of Nations delegates. It is the beginning of a lifelong friendship, with its ups and downs, through which the two men will exchange abundant correspondence.
In 1938, as European nations re-armed for war, Buchman called for 'moral and spiritual re-armament' as the way to build a 'hate-free, fear-free, greed-free world'. Enthusiastic, Philippe Mottu became one of the main activists of Moral Reamament (MRA) in Switzerland. In this capacity he participated in numerous MRA actions at home and abroad, particularly the massive meeting of Palais Baulieu in Lausanne in 1937 (10’000 participants) or the international meeting of Interlaken in 1938.
In 1939 Philippe Mottu was called into active service and joined the "Army and Home" section at the Swiss Army's headquarters, probably at General Guisan's request as the general partly relied on MRA to build up Swiss morale and resistance spirit. With Denis de Rougemont and Theophil Spoerri, he took an active part in the setting up of the Gotthard League, a civil society movement dedicated to countering "defeatism and deceptive propaganda" in the face of intense Nazi propaganda which Switzerland was subject to at the time. "We wanted to proclaim that our country would remain faithful to his multi-secular democratic tradition", he explained.
He then joined the Federal Department of Foreign Affairs in Bern.
The war years In 1940, Philippe Mottu established contact with a German diplomat in Bern, Herbert Blankenhorn, and, through him, with Adam von Trott zu Solz, one of the leaders of German resistance to Nazism. Upon von Trott's invitation, Mottu travelled to Berlin in November 1942 where he meets with other members of the resistance. During a British bombardment, a top German Foreign Affairs official, Hans-Bernd von Haften, asked him: "As Christians, are we allowed to kill Hitler? will be the Caux Foundation's president from 1977 to 1987.
Publications Philippe Mottu wrote several books on international, political and social issues. Building on a vast culture and on a rigorous analysis of his time's trends, he for instance exposed the rise of intolerance and extremism in Judaism, Christianity and Islam; he was searching in which way humanity would adapt to the momentous transformations of the 20th century, and develop a harmonious society in the future, expressing the hope is that humanity will find spiritual resources allowing it to envisage its future with « a measure of serenity".
