Natural equality is a concept that refers to the equality that is found among all humans solely by the constitution of their nature. This equality is the principle and foundation of liberty and is based on the constitution of human nature common to all humans, who are born, grow, live, and die in the same way. The idea of natural equality has been discussed by various philosophers throughout history, including Greek philosophers who believed that all humans are equal, regardless of their social status. In modern times, natural equality has been used as a moral and theoretical ground for majority rule and legitimate, limited government by consent. However, the concept of natural equality can be interpreted in different ways, and some scholars have pointed out that it can be confusing due to the different meanings attributed to it. For example, Pufendorf, a philosopher, referred to natural equality as the idea that humans are equally obliged to obey natural law and that they have similar innate duties towards each other. Hobbes, another philosopher, believed that natural equality contributes to competition and glory, which then produce diffidence. Overall, natural equality is a concept that emphasizes the equality of all humans based on their nature, regardless of their social status or other differences.
