Philosophy is All You Need

By Cyril Soler-Bonnet 6 min read

In 2017, "Attention is All You Need" revolutionized AI by showing that neural network architectures could be simplified by focusing on one fundamental mechanism. Today, the industry is making the opposite mistake: it's complexifying technical stacks—vector databases, embeddings, RAG pipelines—while forgetting the fundamental mechanism.

Philosophy is all you need.

The Problem is Conceptual, Not Technical

Let me be direct: AI doesn't have a technology problem. It has a conceptual architecture problem.

Companies are buying technical solutions. They purchase LangChain, pgvector, Claude API. They hire ML engineers and data scientists. They deploy RAG systems with all the proper infrastructure.

And it doesn't work.

Not because the technology is flawed. The technology is excellent. It doesn't work because they skipped the step that matters: conceptualization.

Before you can code anything, you need to think clearly about what you're building:

  • What entities exist in your domain?
  • How do they relate to each other?
  • What constraints apply?
  • What are the boundaries?
  • What are the dependencies?

You can't build what you can't think clearly about. And most companies haven't thought clearly about their domains.

Natural Language Before Code

Here's the error everyone makes: thinking you can jump straight to implementation.

They open their IDE. They start writing Python. They install libraries. They configure databases. They feel productive because code is being written.

But they're building on sand.

Conceptualization happens in natural language, not in code.

Think about how ontologies are actually built:

  • Ontologies are written in sentences: "A user can have multiple accounts"
  • Constraints are formulated in logic: "If X then Y"
  • Relations are defined conceptually: "is-a", "part-of", "depends-on"

This isn't pseudo-code. This is thinking. And thinking happens in natural language.

Code comes after conceptual clarity. Not before. The moment you start coding before you've achieved clarity, you're embedding confusion into your system. And no amount of clever engineering will fix conceptual confusion.

You Have to See the Boxes First

Everyone loves the phrase "think outside the box." It's inspiring. It's motivating. It's also impossible.

You want to think outside the box? You have to see the boxes first.

This is what philosophy has been teaching for 25 centuries:

  • Identify the categories
  • Distinguish genera from species
  • Trace conceptual boundaries
  • Name what hasn't been named yet

Philosophers don't code ontologies. They think ontologies. And this thinking precedes—and determines—all technical implementation.

When you build an AI system without philosophical rigor, you're not building on solid ground. You're building on assumptions you haven't examined, categories you haven't defined, and relationships you haven't mapped.

The system might run. It might even appear to work. But it won't be able to handle edge cases, because you never thought through what the edges actually are.

When AI Commoditizes

Here's what's happening right now: AI capabilities are becoming abundant.

Everyone has access to Claude. Everyone has access to GPT. Everyone has access to Llama and Mistral and the endless stream of open-source models that keep getting better.

When capabilities become abundant, value migrates. But where?

Value flows to those who have:

  • Proprietary data that's actually structured
  • Conceptual clarity about their domain
  • Ontological rigor in their architecture

The technology is abundant. Clear thinking is rare.

And that's the opportunity. While everyone else is buying tools and hiring engineers, the real competitive advantage goes to those who can think clearly about what they're building.

The bottleneck isn't compute. It's not data. It's not even algorithms. The bottleneck is conceptual architecture.

The Philosophical Method

So what does this actually look like in practice?

Before you write a single line of code, you write in natural language:

  • What are the fundamental entities in this domain?
  • What properties do they have?
  • How do they relate to each other?
  • What can change? What must remain constant?
  • What are the constraints? Where do they come from?

You diagram the relationships. You identify the hierarchies. You trace the dependencies. You find the boundaries.

And only when you can explain your domain clearly, in plain language, to someone who knows nothing about it—only then do you start building.

This isn't busywork. This is the work. Everything else is just translation into code.

Philosophy is All You Need

"Attention is All You Need" simplified neural architecture by identifying what mattered.

"Philosophy is All You Need" simplifies conceptual architecture the same way.

Stop buying tools. Start thinking clearly.

Stop stacking frameworks. Start conceptualizing your domain.

Stop looking for the technical solution. Start looking for conceptual clarity.

Because without it, no technical stack will work. With it, the implementation becomes almost trivial.

Philosophy is all you need.

Need help mapping your conceptual architecture?

I work with companies that have proprietary knowledge bases and need someone to see—and structure—the boxes first.
