The Need for Rules (Leaving Cert Politics and Society): Revision Notes
The Need for Rules
Understanding why rules exist and how they function is essential for examining power and decision-making in any society. Rules form the backbone of organised communities, from schools to entire nations, and their presence shapes how individuals interact and make collective decisions.

Why rules are necessary
Rules serve several crucial functions in maintaining social order and protecting individual welfare. The primary purpose of establishing rules is to create order and stability within communities, allowing people to live, learn and work together safely and effectively.
Rules prevent and resolve conflict by establishing clear expectations for behaviour and creating fair processes for addressing disputes. When everyone understands what is expected of them, misunderstandings and conflicts become less likely to occur.
Another vital function is that rules protect rights and freedoms. Examples include equality rules in schools that prevent discrimination, or safety regulations on roads that protect everyone's right to travel safely. Without these protective measures, vulnerable individuals could be exploited or harmed.
The absence of rules creates serious social problems. Without established guidelines, societies risk descending into chaos, violence, and domination of the weak by the strong. This creates an environment where those with power can abuse others without consequence.
Finally, shared rules build trust within communities. When everyone follows the same standards and expectations, individuals can rely on others to behave predictably and responsibly.
Types of rules
Rules can be categorised into two main types, each serving different purposes in society.
Formal rules (laws) are official regulations created by the state and enforced through institutions like the Gardaí and court system. These include road safety laws, health and safety regulations, and equality legislation. Formal rules carry legal consequences for those who break them.
Informal rules (norms) are unwritten expectations that develop within families, schools, teams and other social groups. Examples include queuing politely, showing respectful behaviour to teachers, or following team protocols. While breaking these norms may not be illegal, it can damage one's reputation and cooperation with others.
These two types of rules interact closely. Breaking an informal norm might not result in legal punishment, but it can still have significant social consequences for how others view and treat the person involved.
Case studies from Ireland
Several practical examples demonstrate how rules function effectively in Irish society.
Case Study: Road Safety
Speed limits, seatbelt requirements, and drink-driving laws are designed to protect lives. The Gardaí enforce these regulations, while public campaigns like "Slow Down Day" help reinforce compliance and raise awareness.

Case Study: School Codes of Behaviour
Anti-bullying policies, attendance requirements, and respect rules protect students' right to learn and maintain wellbeing. These codes are typically reviewed and applied by boards of management to ensure fair and consistent implementation.
Case Study: Workplace Safety
Health and Safety Authority standards require risk assessments and proper training to reduce accidents and create safer working environments. These rules demonstrate how regulations protect both employers and employees.
When rules are questioned
Not all rules remain appropriate forever, and some may become unjust due to being discriminatory or outdated. Democratic societies provide mechanisms for questioning and changing problematic rules.
Democratic change can occur through various means, including student voice initiatives, petitions, protests, and legal challenges. These processes allow communities to reform rules that no longer serve their intended purpose or that unfairly disadvantage certain groups.
The key principle is that while rules are necessary, they must also be fair, proportionate, and revisable. Good rules can be modified or replaced when circumstances change or when they are shown to cause harm rather than benefit.
Key political thinkers
Two influential philosophers provide important perspectives on why rules and government authority exist.
Thomas Hobbes wrote about these ideas in his work Leviathan. He argued that in a world without common rules (which he called the "state of nature"), life would be "solitary, poor, nasty, brutish, and short". According to Hobbes, people therefore agree to rules and authority to secure peace and safety. His theory emphasises why rules are essential for preventing chaos and protecting everyone's welfare.
Hobbes believed that without rules and authority, human nature would lead to constant conflict and violence. His famous phrase describes what life would be like in this "state of nature" - a world without government or social rules.
John Locke presented a different perspective in Two Treatises of Government. He believed that people possess natural rights including life, liberty, and property. For Locke, laws are legitimate when they protect rights, apply equally to everyone, and are made with consent through representation. His theory emphasises what good rules should be like rather than just why they are needed.
Evaluation of key theories
Hobbes explains the fundamental need for rules by showing how they prevent chaos and social breakdown. His approach focuses on the practical necessity of having some form of authority and regulation.
Locke explains the limits and purposes of rules, arguing that they must protect rights and remain accountable to the people they govern. His approach emphasises the quality and legitimacy of rules rather than just their existence.
Together, these thinkers suggest that rules should secure both order and rights. When a rule undermines individual rights or fails to serve the common good, it needs review or reform to maintain its legitimacy and effectiveness.

Exam Success Tips
When answering exam questions on this topic, students should:
- Use everyday Irish examples from roads, schools, and workplaces to demonstrate how rules function and ensure fairness in practice
- Contrast formal versus informal rules and explain how these different types interact with each other
- Reference Hobbes (emphasising order and preventing chaos) and Locke (emphasising rights and consent) to provide theoretical framework for evaluation
- Use key terminology accurately: order, consent, legitimacy, rights, proportionality, enforcement
Key Points to Remember:
- Rules are essential for order, safety, trust, and rights protection in any community
- Formal rules (laws) and informal rules (norms) work together to regulate behaviour
- Irish examples like road safety, school codes, and workplace standards show rules in action
- Hobbes argued rules prevent chaos; Locke argued rules must protect rights and rest on consent
- Good rules must be fair, proportionate, and open to reform when they become unjust
