Why Jaime Balmes argued that no single formula can explain the entire universe

In short: Spanish philosopher Jaime Balmes rejected the idea that one pillar could support all human knowledge. Instead, he proposed a tripartite system of truth—subjective, rational, and objective—arguing that relying on a single foundation, like the Cartesian cogito, inevitably leads to a distorted view of reality and human thought.

Jaime Balmes, a 19th-century Spanish thinker dubbed the Prince of Modern Apologetics by Pope Pius XII, remains a singular figure in philosophy. Born in 1810 in Vic, Balmes developed a system that challenged the reductionist tendencies of his contemporaries. While often simplified as a philosopher of common sense, his work is far more complex, positing that metaphysics must rest on three irreducible pillars: consciousness, evidence, and intellectual instinct.

Balmes argued that truth manifests in three distinct classes. Subjective truths, such as personal sensations, rely on the criterion of conscience. Rational truths, which are logical or mathematical, depend on evidence. Finally, objective truths—the reality perceived by all—are accessed through common sense or intellectual instinct. He contended that these methods are not interchangeable; attempting to force one into the domain of another leads to error. For instance, while Descartes famously reduced existence to the cogito, Balmes argued this merely captures a subjective truth of consciousness, which is then transformed into a logical syllogism, risking the reduction of human experience to mere intellectual mechanics.

This framework extends beyond abstract metaphysics. In his 1844 work on value, Balmes solved the classic paradox of why a diamond is worth more than bread by introducing the concept of marginal use. His broader philosophical project, detailed in works like 'Filosofia Fundamental', sought to preserve the fullness of natural knowledge. By denying that any single formula can unlock the universe, Balmes championed a philosophy rooted in the totality of human experience, arguing that while specific foundations like the cogito are true in their own right, they become false when they claim exclusivity over the vast, multifaceted landscape of human thought.

Balmes died in 1848, leaving behind a legacy that continues to serve as a counter-argument to historical narratives that prioritize Protestant thought in the development of modern society. His insistence that philosophy must begin by identifying the specific kind of truth being sought remains a vital, if often overlooked, contribution to the history of ideas.
