of Technology, Room 20d, Zurich 6

Zurich, Date as per P. 0. stamp. Dear Sir,

In our first circular letter, i t was announced that the International Congress for the Philosophy of Science, Zurich 1954, had been recognized as a regular, second congress of the International Union of the Philosophy of Science.

1. Ref . this first circular letter In this letter i t was established that the Congress will take place

from Monday 23rd. to Saturday 28th. August 1954, in Zurich. We would advise you also that the Board requests all speakers to arrange their papers within the framework by the following themes :

a ) Discrimination of tendencies in the philosophy of science today, showing possible differences and similarities among these.

b ) The importance of the philosophy of science to scientific research.

2. Notification of the delivery of papers We are very glad that notification has already been received of more

than 1000 papers to be delivered. Unfortunately, i t has not yet been possible to communicate directly with every contributor ; but this will be remedied during the coming weeks. In general we would remark that some notifications appear not to show adequate regard to the themes fixed by the Committee. The Scientific Chairman cannot acknowledge papers, whose subjects fall outside the scope of the themes arranged: it can be promised neither that there will be sufficient time for such papers to be delivered, nor that such papers would be admitted into the Publications of the Congress.

3. Organisation of the Congress Under the chairmanship of Prof. Dr. Wolfgang Pauli (ETH, Zurich),

there will be a symposium to discuss fundamental questions of physics.
