1. The Problem. The purpose of this paper is twofold. One aim is to examine briefly the criteria basic to the notions of the culture area and the language area; the second is to indicate a method which would allow for the construction of systems which could profitably be compared and held correlate in any problem involving, on the historical level, the development and diffusion of cultural and linguistic patterns, and, on the synchronic level, the precise nature of that complex of human behavior patterns, linguistic and non-linguistic, which is characteristic of man in society.

1. Outline of the Project. This paper is intended to be a progress report on a project in philosophy of science. The immediate stimulus of this report is the eightieth birthday of E. A. Singer, Jr., who was the inspiration of the project, and, needless to say, though responsible for the whole is not responsible for the misconceptions in the specific parts.

When in the course of our work we are uncertain, we sometimes become more concerned with our methods than with the content of our problems. We then try to clarify our conceptions and tighten our procedures. And as we re-examine studies that we feel have turned out well, we create conscious models of inquiry with which we try to guide our own work-in-progress.

1. Introduction. It is an amazing thing that, unlike pebbles, clouds and stars, the smallest building stones of Nature—the electrons, the protons and the neutrons—are all completely uniform. There seems to be a necessity in Nature for systems of a very special form, and one can wonder now what kind of necessity this is. I believe that this can only be a mathematical necessity, that consequently the principle of Nature is a mathematical one. How else could Nature obey the mathematical laws of physics if it were not because of her own principle? It can be argued that these mathematical laws, like Newtonian mechanics, the classical theory of electromagnetism and the quantum theory of the electron are all some form of beginner's luck, and that continued investigation will reveal Nature as more and more mysterious and irrational. If that were true, one might as well give up the pursuit of physics completely! But on one hand modern physics has discovered what we believe to be the elementary particles of the material world, and on the other hand it comes out that at least a part of these elementary forms obey mathematic laws to a very high degree of accuracy.

The following statement from James’ 1884 essay in Mind (12) is repeated in his later work (10, pp. 100–101) and appears often in secondary sources as a summary of his celebrated theory of the emotions:

The so-called “mind-brain” problem affords the greatest opportunity for the cooperation of philosophy and science in the advancement of knowledge. In this paper we will outline pertinent facts already learned about the human mind from neurological disciplines, and, using some hypotheses from outstanding workers in neurobiology, we will relate this material to some important philosophical problems. Our proposal is to examine these problems in the light of knowledge gathered from the scientific disciplines, and we hope to demonstrate how this method may eventually clarify some of the confusion and suggest certain solutions.

To this date Roger Bacon remains one of the controversial and colorful figures in the history of empirical science. This paper is an attempt to ascertain his views regarding the nature and function of empirical science and to compare his writings on this topic with those of the more famous Francis Bacon. The ground for comparison is the fact that both men have often been cast in the same role in the history of science; i.e., they have both been acclaimed as the first in the western world to emphasize and bring out the importance of experimental method in the accumulation of knowledge. In this connection Francis, of the sixteenth century, has long been acknowledged as the father of the experimental method in preference to Roger, of the thirteenth century. In effect, therefore, this paper probes the relative merits of the claims for each thinker.
