Abstract

Figure 6 shows a logic diagram that traces our progress so far and what to expect in Chapter 2. A continuation of this diagram, Figure 18 in Chapter 3, will complete the logic for predicting human survival.

When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of a science, whatever the matter may be. —Lord Kelvin
