Extract

It is the purpose of this note to comment on some important problems which have been already vividly discussed by several authors. Besides the well known former discussions of Schrödinger and J. v. Neumann I should like to mention here especially H. Margenau's article, “Critical Points in Modern Physical Theory,” (3) which strongly influenced my present discussion.

∗

The following questions were sent to each of the invited contributors of this symposium: 1a) What is a physical system, and what is meant by the state of a physical system in classical physics and in quantum mechanics? 1b) What philosophical clarification in the concept of a state has resulted from quantum theory? 2a) What is the status of particles in quantum mechanics? 2b) What philosophical changes of the particle concept, and in the concept of mechanism, have resulted from the quantum theory? 3a) In what ways has “causal explanation” been modified by modern quantum theory? 3b) How do these changes affect the philosophic problem of determinism?

The symposium was conducted by Prof. Henry Margenau, with the assistance of the editor. Further papers will appear in the next issue by E. Kemble and W. H. Werkmeister. Additional contributions on the subject are welcome.
