There are certain fundamental concepts and principles that are considered to be unchanging or immutable. Here are a few examples:
Laws of Logic: The laws of logic, such as the law of non-contradiction, the law of identity, and the law of excluded middle, are fundamental principles that form the basis of rational thought. They are considered to be unchanging and universally applicable.
Mathematical Truths: Mathematical truths and concepts, such as the properties of numbers and geometric shapes, are believed to be eternal and unchanging. Mathematical principles remain consistent across time and space.
Laws of Physics: While our understanding of the laws of physics may evolve and deepen over time, there are certain fundamental principles, such as the conservation of energy or the laws of thermodynamics, that are considered to be constant and unchanging throughout the universe.
Moral and Ethical Principles: Although moral and ethical beliefs can vary across cultures and individuals, there are certain fundamental principles, such as the Golden Rule (treating others as you would like to be treated) or principles of justice and fairness, that are considered to be enduring and unchanging.
Human Nature: While individual behavior and societal norms can change over time, there are aspects of human nature that are considered to be relatively stable. Certain fundamental needs, desires, and psychological tendencies are believed to be inherent to human beings and remain consistent across generations.
It is important to note that these examples represent general philosophical and scientific viewpoints. Our understanding of the world and its principles is subject to refinement and revision as new knowledge and perspectives emerge.
