Rotenstreich: "FREEDOM FROM VALUES" EXAMINED 87 PREFACE In accordance with a suggestion made in the preceding assembly of the Institute in Helsinki (1970), as theme of the Entretiens in Amsterdam was chosen: Human sciences and the problem of values. As usual the organization of the Entretiens was committed to a local committee in close collaboration with the office of the Institute in Paris. The confer ence was held from 8 till II September 1971 in the so called Trippenhuis (house where lived the family Trip in the 17th and 18th century), seat of the Royal Netherlands Academy of Sciences and Letters. The sessions were attended by about 70 people, not only members but also some invited colleagues and assistants representing the philosophers in the Dutch universities. The papers were multiplied and distributed to the participants some time before the beginning of the conference. By so doing each speaker (rapporteur) could restrict himself to a short summary of the main points of his paper or a short comment as introduction, immediately followed by a general discussion.
