Computer science has long regarded reasoning as a defining characteristic of intelligence, yet recent advances in foundation models increasingly blur the distinction between learning and reasoning. This article argues that the more fundamental question is not how intelligent systems reason, but why explicit symbolic reasoning is needed in the first place.  \nWe propose the Compression Principle: every computational model is a simplified representation of reality, and explicit symbolic reasoning compensates for information omitted during that simplification. From this principle we derive the Modeling–Reasoning Trade-off: as computational models preserve richer representations of the world, the need for explicit symbolic reasoning correspondingly decreases. This perspective offers a unified explanation for both the historical success of symbolic methods and the remarkable effectiveness of modern foundation models.  \nParadoxically, the same development increases the importance of symbolic methods for humans. As intelligent systems become more capable and less transparent, symbolic representations increasingly serve as interfaces through which humans specify requirements, verify behavior, regulate autonomous systems, and establish trust. We therefore argue that the future of symbolic methods lies not primarily as the computational engine of machine intelligence, but as the symbolic interface between increasingly capable AI systems and the humans who build, govern, and depend upon them.  \n“The map is not the territory.”  \n—Alfred Korzybski  \n1 Why Do Intelligent Systems Reason?  \nSymbolic reasoning has long been regarded as one of the defining characteristics of intelligence. From Aristotle’s syllogisms to modern formal verification, from theorem proving to automated planning, computer science has devoted decades to developing increasingly sophisticated methods for symbolic reasoning. Indeed, much of our discipline is built upon the premise that intelligent behavior arises from the ability to derive new knowledge from existing knowledge through logical inference [5, 6, 8] .  \nRecent advances in artificial intelligence (AI), however, challenge this long-standing perspective. Foundation models routinely generate software, translate natural languages, answer scientific questions, and increasingly interact with the physical world—often without relying on explicitly constructed symbolic knowledge bases or handcrafted reasoning rules [2, 7, 11] . Their remarkable capabilities have reignited a familiar debate. Should future AI systems continue to rely on symbolic reasoning? Will statistical learning ultimately replace symbolic methods? Or will intelligence emerge from some combination of the two?  \nThese questions have inspired decades of research. Yet they all share an implicit assumption: that reasoning itself is a fundamental component of intelligence. This article begins by questioning that assumption.  \nRather than asking how intelligent systems reason, we ask a more fundamental question:  \nWhy do intelligent systems need to perform explicit symbolic reasoning at all?  \nThe distinction is subtle but important. Questions about how lead us to design better reasoning algorithms, richer logical systems, or more expressive symbolic representations. Questions about why instead ask what computational role explicit reasoning actually serves. If that role can be  \nAuthor’s Contact Information: Jun Sun, Singapore Management University, Singapore, Singapore, [jun.sun@smu.edu.sg](jun.sun@smu.edu.sg).  \n, Vol. 1, No. 1, Article .
