Who is simpler, a cat or a cat? - briefly
A cat is identical to itself, so there is no difference in complexity between the two. The question is inherently redundant.
Who is simpler, a cat or a cat? - in detail
The question of simplicity between two identical entities, such as a cat and a cat, is inherently paradoxical because it compares the same subject to itself. A cat, as a living organism, possesses a defined set of biological, behavioral, and physiological characteristics that remain consistent across individuals of the same species. When comparing a cat to another cat, the comparison does not yield meaningful differences in simplicity or complexity because both entities share the same fundamental traits. The concept of simplicity in this context becomes irrelevant, as there is no variation or distinction to evaluate. Instead, the focus shifts to understanding the inherent nature of cats, which includes their instincts, social behaviors, and adaptability. Cats, as a species, exhibit a balance of simplicity in their basic needs—such as food, shelter, and companionship—and complexity in their interactions and survival strategies. Therefore, the question itself is a tautology, as it seeks to compare identical entities, rendering the notion of simplicity or complexity inapplicable.
