In every human being there are five complete systems or depart ments. Every person is born with one or two of these systems more highly developed than the others. When one system predominates far above the other four, that person is an extreme type. When all systems are practically equal and even in their development, that individual is called a balanced type. But this rarely happens. The majority of human beings approximate a somewhat balanced type, but the practiced eye can see, even in these cases, which system predominates. For the purpose of emphasis reference herein will be made to extreme types. Combinations will be referred to later.
