'''The Concept of "Structure All the Way Down"''': Analyzing "The Regress." (See Article 752). "If" "Mathematics" is "The Study" of "Structures," "What Are" "Structures Made Of"? **"Category Theory"** "Says": "Objects" and "Morphisms" — "But" "What Are Those"? "If" "We Answer" **"More Structures,"** we "Face" "An Infinite Regress." "Some Structuralists" "Embrace" this — "Reality" is **"Structure All The Way Down."** "Others" see "A Need" for "A Foundation" — "A Bedrock" of "Non-Structural" "Existence." "The Regress" "Remains."
