ABSTRACT
When doing science, scientists gather information and formulate assertions about the characteristics of entities. These assertions are the building blocks of science, possibly culminating in theories, perhaps the most sought-after product. The phrase science or art clearly indicates that the definition applies to an indescribable variety of kinds of human activities even if they are limited to what is commonly identified as fields. Surely mathematics and philosophy qualify, but the practitioners do not identify themselves as scientists or artists, even though they may refer to the products of their activities as theory or theories. When a statement is identified as synthetic, the identification suggests that the statement is testable in principle, directly or indirectly. It is refreshing to point out that the testability issue haunts the physical sciences as well as sociology. An entity is any event or thing or category of them.
