Final answer:
Equality is not the fundamental principle in nature due to its complex manifestations in physics, societal structure, and legal contexts, where the balance of equality with liberty creates an environment where equal outcomes are not the focus, but rather equal opportunities and liberties.
Step-by-step explanation:
Equality is not considered the fundamental unit/principle in nature because the concept itself manifests differently across various contexts, such as in physics, social structures, and legal frameworks. In the realm of physics, forces at certain high-energy conditions are theorized to be unified, though not necessarily equal, pointing to the complexity of nature's workings. In social terms, the United States, through its Declaration of Independence and Fourteenth Amendment, professes ideals of equality.
Nonetheless, historiographical and sociopolitical analyses often reveal a gap between these aspirations and reality. Inherent in the pursuit of equality is the tension with liberty, particularly in democratic systems, where balance is sought not necessarily in outcomes but in opportunities and liberties. This balance is continuously redefined by courts and legislatures amid evolving societal norms and is influenced by voices and perspectives historically marginalized or excluded from political philosophy, as noted by Aristotle's views.
The challenge thus does not lie in establishing equality as a principle but in its practical application, ensuring the balance of liberty and the protection of basic rights without demanding homogeneity in outcomes. Conceptually, while equality in justice or opportunity is asserted as a noble aim, the diversity of life and multiple interacting factors make equality as a fundamental natural unit both an impractical and non-universal precept.
