Well, the parts of philosophy that are axiomatic, have been absorbed by mathematics already.

There is indeed an ongoing process of mathematical conquest, annexation and infiltration, not just in philosophy, but also in other knowledge fields, assisted by relentless progress in software development, but I do not believe that all knowledge can be axiomatized.

In fact, it is mathematics itself that guarantees the impossibility to axiomatize all truth.

My interlocutor seem to claim that Mathematics with its Axioms [he claimed to be platonic] is King and is a subset of philosophy.
If I am right, how can can I explain the mathematics like science and metaphysics are merely tools of philosophy?

To respond to your interlocutor's claim that mathematics (with its axioms, which they consider Platonic) is the "king" and a subset of philosophy, while demonstrating that mathematics, like science and metaphysics, are tools of philosophy, you can build your case as follows:

1. Philosophy as the Grounding Discipline
Philosophy is the broader discipline that examines the foundational principles, assumptions, and methodologies underlying all fields of knowledge, including mathematics. Unlike mathematics, which operates within its own internal axiomatic systems, philosophy explores:

The nature of axioms (Are they synthetic, analytic, or rooted in intuition? Are they human constructs or mind-independent?).
Epistemological status (How do we know mathematical truths? What justifies their universality?).
Ontological status (Are mathematical objects real in a Platonic sense or human-dependent?).
Thus, mathematics depends on philosophy for its grounding in both epistemology and ontology, making it a subset of philosophical inquiry rather than its ruler.

2. Mathematics as a Tool of Philosophy
Mathematics serves as a tool in philosophical reasoning because it provides a formal language and methodology for expressing and testing ideas. However, mathematics by itself cannot answer questions about:

Its own nature (Is it discovered or invented?).
Its application to the physical world (Why does mathematics describe nature so well?).
Its limitations (What are the boundaries of mathematical knowledge?).
These questions are inherently philosophical. For instance, Kant’s investigation into the synthetic a priori nature of mathematical judgments shows that philosophy provides the necessary framework for understanding the role and scope of mathematics.

3. Mathematics is Not Self-Justifying
While mathematics is internally rigorous and coherent, it does not justify itself. Its axioms and systems are chosen, constructed, or interpreted within a philosophical framework. For example:

In a Platonic framework, mathematical truths exist independently in an abstract realm.
In a Kantian framework, mathematical truths arise from the human forms of intuition (space and time).
In a formalistic framework, mathematics is a game of symbol manipulation without intrinsic meaning.
Philosophy determines which framework is adopted and evaluates their coherence, making philosophy the higher discipline.

4. Mathematics, Science, and Metaphysics are Specialized Tools
Philosophy investigates the foundations and limits of all specialized disciplines:

Science is the empirical investigation of the phenomenal world, guided by philosophical questions about causality, observation, and theory-ladenness.
Mathematics is the study of abstract structures, guided by philosophical inquiry into its nature and applicability.
Metaphysics is the study of being, reality, and causality, which philosophy examines critically for coherence and justification.
Each of these fields provides tools to address specific questions but operates within a framework shaped and examined by philosophy.

5. Kant’s Perspective: Mathematics is Not King
From Kant's point of view, mathematics operates within the domain of phenomena, relying on the human conditions of sensibility (space and time) and cannot extend to things-in-themselves. Philosophy, on the other hand, addresses broader questions, such as the limits of reason, the nature of reality, and the conditions for possible experience. Mathematics is a tool for reasoning about phenomena but does not govern the foundational questions philosophy addresses.

6. An Analogy: Philosophy as an Architect, Mathematics as an Engineer
Philosophy can be likened to the architect of human knowledge—it designs the overarching framework and investigates the principles upon which structures (disciplines) are built. Mathematics, like engineering, provides the tools and techniques to construct specific parts of the structure. While mathematics is indispensable, it is subordinate to philosophy because it works within a framework that philosophy defines.

Response to the "King" Claim:
To summarize your argument to your interlocutor:

• Mathematics, while a highly specialized and rigorous discipline, is not the "king" of knowledge. It is a subset of philosophy because philosophy examines the foundational assumptions and implications of mathematics, such as its epistemological and ontological status. Just as science and metaphysics are tools shaped by philosophical inquiry, mathematics is a tool used to express and explore specific domains of knowledge, but it relies on philosophy to justify its principles, applications, and limitations. Far from being independent, mathematics derives its power and scope from the philosophical frameworks in which it operates.

This positions philosophy as the overarching discipline that unifies and examines all domains of knowledge, including mathematics.
