Alfred North Whitehead’s A Treatise on Universal Algebra pioneers the study of algebraic structures as unified systems, proposing a universal algebra—a framework to compare diverse algebras (e.g., Boolean, Grassmann’s exterior algebra) via symbolic logic systems governed by formal equivalence. He introduces algebraic schematism, where operations like addition or meet/join in lattices are redefined as abstract combinatory rules detached from numeric interpretation, and isomorphic equivalenceto map structures (e.g., quaternions to spatial rotations) via type hierarchies. Central are Grassmann’s calculus of extension, reinterpreted through Whitehead’s relational product (combining vectors and multivectors), and Boolean algebra as a logic of class-inclusion. The text critiques arithmetic fetishism—prioritizing number-based algebras—and explores operational analogy between algebras (e.g., matrix multiplication vs. syllogistic logic). Though incomplete (planned second volume unwritten) and later eclipsed by category theory, this work inspired Noether’s abstract algebra, prefigured Bourbaki’s structuralism, and laid groundwork for computational type theory, securing its legacy as a daring early synthesis of algebraic diversity and logical unity.
