“Look here, Bill,” said Tom, “let’s take him out to the boat.”

“What for?” demanded Bill.

“Yes,” nodded the scholar. “Scientists have watched people and studied them, just as we study animals, until they have learned that almost all people will act in much the same way under certain ways of stimulating them.”

“I know,” agreed Tom. “We all want to run when we are scared; we all do, if there is a fire and a panic.”

“Yes,” chimed in Cliff, “and when we think about something nice we smile, and if we think about a lemon, we act and feel almost as though we tasted it.”
