A constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed. These rules together make up, i.e. constitute, what the entity is. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a written constitution; if they are written down in a single comprehensive document, it is said to embody a codified constitution.

The Golden Rule or ethic of reciprocity is a moral maxim or principle of altruism found in nearly every human culture and religion, suggesting it is related to a fundamental human nature. The maxim may appear as either a positive or negative injunction governing conduct:

• One should treat others as one would like others to treat oneself (positive or directive form).
• One should not treat others in ways that one would not like to be treated (negative or prohibitive form).
• What you wish upon others, you wish upon yourself (empathic or responsive form).
