Final answer:
The author describes beatings as a means to curb unwanted behavior in children, but it's noted that such corporal punishment can lead to fear and increased aggression in children. The 'king in his dominions' metaphor reflects the absolute authority of superintendents in administering discipline. Lesser punishments are deemed 'childish' as they were less harsh than physical punishments like whipping.
Step-by-step explanation:
The author explains the purpose of beatings or physical punishment during his childhood as a method intended to decrease undesirable behavior. While physical discipline such as spanking was once common and not considered abuse as long as no injury resulted, it's also stated that it may teach fear, cause children to become more aggressive, and lead to antisocial behavior and delinquency. The mention of the superintendent being referred to as "a king in his dominions" likely reflects a recognition of the absolute power such figures had to administer punishment and enforce discipline in the past.
In the given context, less severe forms of punishment like the privation of food and the "blackhole" might be perceived as 'childish' because they were less physically painful and possibly less psychologically damaging compared to the trauma associated with a whipping. Whipping, by contrast, was a much harsher form of physical punishment that could have longer-lasting effects, both physically and emotionally, on a child.
