PRIMITIVE BEHAVIOR

CHAPTER I

The Comparative Study of Cultures

The variable stars are our main measuring tools for getting out into the universe beyond and outside our own system. It is very difficult to find out anything about our own milky way because we ourselves are inside this system. We can study it only by studying the other systems, and the more we learn about them directly, the more we will learn about our own system, indirectly.1
