The Philosophy of Invariance
The philosophy of invariance examines the concept of constancy or unchanging nature within various contexts, including science, mathematics, ethics, and metaphysics. This philosophical exploration seeks to understand what remains constant amidst change and why such constancies are significant for our comprehension of reality, knowledge, and truth.
Key Concepts in the Philosophy of Invariance
Definition of Invariance:
Concept: Invariance refers to properties or principles that remain unchanged under specific transformations or conditions.
Argument: Identifying invariances helps in understanding the fundamental nature of systems and theories, providing a stable foundation for analysis and interpretation.
Invariance in Science and Mathematics:
Physical Laws: Many physical laws, such as the laws of motion and conservation laws, are considered invariant under transformations like time shifts or spatial rotations.
Symmetry: Invariance is closely related to symmetry in physics and mathematics. For example, the invariance of physical laws under certain symmetries leads to conservation laws according to Noether's theorem.
Mathematical Constants: Constants like π (pi) and e (Euler's number) are examples of invariance in mathematics, holding the same value across various contexts.
Invariance in Metaphysics:
Universal Principles: In metaphysics, invariance pertains to principles or truths that remain constant across possible worlds or different contexts.
Identity and Change: Philosophers explore how identity can persist over time despite changes, focusing on the invariant core that defines an entity.
Ethical Invariance:
Moral Principles: The idea that certain ethical principles are invariant, holding true regardless of cultural or situational differences.
Universal Ethics: This approach argues for the existence of universal moral truths that apply to all rational beings.
Theoretical Debates and Implications
Role of Invariance in Scientific Theories:
Concept: Invariance as a criterion for the validity and robustness of scientific theories.
Argument: Scientific theories that exhibit invariance under transformation are often considered more fundamental and reliable.
Philosophical Implications of Mathematical Invariance:
Concept: The philosophical significance of invariant mathematical properties and structures.
Argument: The constancy of mathematical truths supports the notion of an objective mathematical reality, independent of human perception.
Ethical Relativism vs. Invariant Ethics:
Concept: The debate between ethical relativism, which denies invariant moral principles, and invariant ethics, which upholds them.
Argument: While ethical relativism emphasizes cultural and contextual differences, invariant ethics seeks universal moral truths applicable to all.
Metaphysical Invariance and Identity:
Concept: The persistence of identity amidst change and the metaphysical basis for invariance.
Argument: Philosophers debate whether there are essential properties that remain invariant to preserve identity through change.
The philosophy of invariance explores the concept of constancy across different domains, from science and mathematics to ethics and metaphysics. By understanding what remains unchanged amidst transformations, this philosophical inquiry provides insights into the fundamental nature of reality, the stability of scientific theories, and the universality of ethical principles.

“Your brother is adorable.” The cashier cooed at Danny, peering over the counter with a smile. “What’s his name?”
Danny looked down to the surly, scowling little de-aged Batman currently holding onto his hand, glaring up at the cashier with bright blue eyes.
Things had already been bad enough when he’d gotten caught in a fight in Gotham, but things went from bad to worse when a magician had hit Batman with a de-aging spell and then shoved them through a portal.
Into a different fucking dimension.
Because of course neither of their lives could be easy. And now the two of them were stuck in Iowa in the middle of nowhere, at a truck stop gas station, trying to go on a cross-country roadtrip to reach the nearest hero city and get home.
He looked up and smiled awkwardly, trying to come up with a name off the top of his head — one of the heroes called Batman ‘B’ when he got hit right? B for Batman, right. B… B… Bee… Bees.
“Buzz.” He said, and tried not to grimace as the cashier’s face warped with surprise. “Like the astronaut.”
This was gonna be a long trip.
