Abstract Nonsense

Abstract Nonsense is a playful term used in mathematics, particularly in category theory, to describe highly general, structural reasoning that often relies on abstract concepts like objects, arrows, and functors. Instead of focusing on specific examples, it emphasizes universal properties and relationships, allowing mathematicians to prove general results applicable across many different areas. While the name might imply a lack of substance, it actually reflects a powerful, high-level approach that streamlines complex proofs by focusing on the essential structure rather than details.
