...which attempts to pull together some of the main themes of the preceding six essays and to point out the dangers of overes­timating the importance of politics in the lives of men.

Today, three centuries after Newton, gravitation is still one of the enigmas of science. "It may well be the most fundamental and least understood of the interactions," says Robert H. Dicke. In all of the efforts that have been made to formulate a unified physical theory the big challenge has always been to bring gravitation within the theoretical framework. One of the most basic problems is to define the nature of the phenomenon. According to Einstein's general theory of relativity, the theory that is currently accepted (often with some reservations), gravitation is equivalent to a motion. This assertion implies that, while it has some of the characteristics of motion, it is actually not a motion. The objective of the present discussion is to examine the validity of this conclusion.

...in which it is argued that although an individual's values can be neither rational nor irrational, the individual may be able to change and hopefully improve-his values by a rational process.

1. Since what an individual values is not necessarily what he should value, his value system is potentially improvable.

2. Children acquire their initial set of values from other individuals in their environment.

3. However the fact that some values are acquired from one's environment does not mean that all values are so acquired.

4. Rational change of values is possible, but only with the aid of the individual's present set of values.

5. The "man of action" must assume that his present values are valid.

6. The "man of contemplation" must assume that his present values are at least partially invalid.

Abstract: Analysis of the data from observation shows that gravita­tion and the recession of the distant galaxies are negative (inward) and positive (outward) scalar motions respectively, and that some other basic physical phenomena not currently recognized as motions are also motions of this same type. Identification of the scalar nature of these motions enables clarification of a number of long-standing issues in physical science.

AROUND UNEXPECTED CORNERS

About twenty years ago Dr. James B. Conant, at that time president of Harvard University, gave a talk to a group of chemists and chemical executives in which he expressed serious concern over the effect on scientific progress that was likely to result from the virtual disappearance of what he called the “uncommitted investigators”, a term which he applied to those individuals who carry on scientific research work on their own initiative, with­out support from or direction by the established research agencies. As Dr. Conant put it, these individuals “could investigate what they pleased when they pleased, or break off research at any point. They were as free as the wind because they had no program except the ever-changing one in their own minds”.
