Since the turn of the century there has been a strong trend to break through the wall which has separated philosophy from the “special sciences” and to investigate the problems which require a good judgment in both philosophy and science. The evolution of science itself and the increasing relevance of science in human life have given immense momentum to this trend. But this momentum could not be appreciated in its actual strength because scientists who wanted to raise their voices had (...) trouble in finding a Journal where they could communicate with the people who were interested, for almost all the scientific journals were devoted exclusively to technical papers. In founding Philosophy of Science Dr. Malisoff started the construction of a channel by which this important flow of scientific investigation could reach its public. This line of thought found in the journal a possibility of self-expression and it became a real force in the life of the community of scientists and scholars, and even of educated men in general. From the first volume, papers were published which have later been quoted in every discussion about the philosophy of science. I mention, as an example only, R. Carnap's paper on Testability and Meaning. Nobody who has wanted information and stimulation in this modern field of investigation could get it without looking into Malisoff's Philosophy of Science.
