Chapter 7 Pattern Taxonomy

 Classifying the World's Patterns

Part 1 — Understanding Pattern Taxonomy




Learning Objectives

After studying this part, you will be able to:

  1. Define Pattern Taxonomy.

  2. Explain why patterns need classification.

  3. Distinguish different dimensions of pattern classification.

  4. Apply the Pattern Taxonomy Framework (PTF).

  5. Understand how experts build Pattern Libraries.

  6. Explain how AI benefits from Pattern Taxonomies.

  7. Classify patterns using multiple perspectives.


7.1 Introduction

Imagine visiting a library with ten million books.

Every book is placed randomly.

There are no shelves.

No catalog.

No subjects.

No index.

Finding a single book would be nearly impossible.

Now imagine the same library with books organized into:

  • Science

  • Literature

  • History

  • Medicine

  • Engineering

  • Business

Finding information becomes effortless.

Knowledge becomes useful because it is organized.

Patterns are no different.

The world contains millions of recurring patterns.

Without organization,

they become difficult to remember,

compare,

teach,

or reuse.

Pattern Thinking therefore requires its own classification system.

This chapter introduces that system.


7.2 The Central Idea of This Chapter

Recognizing patterns is valuable.

Classifying patterns is transformational.

Classification allows us to:

  • compare patterns

  • discover relationships

  • build Pattern Libraries

  • transfer knowledge between disciplines

  • improve AI reasoning

The central question is:

How can we organize the world's patterns into a coherent system?


7.3 What Is Pattern Taxonomy?

Definition

Pattern Taxonomy is the systematic classification of recurring patterns according to their structure, behaviour, function, relationships, scale, and level of abstraction.

Taxonomy creates order from diversity.

Instead of thousands of unrelated observations,

we obtain organized knowledge.


Example

Suppose you observe these systems:

  • River

  • Blood circulation

  • Supply chain

  • Internet packets

  • Traffic

Although they appear unrelated,

they all belong to one Pattern Family:

Flow

Taxonomy groups them together.


7.4 Why Pattern Taxonomy Matters

Experts rarely memorize isolated examples.

They remember categories.

Doctors remember disease families.

Biologists remember species.

Lawyers remember legal principles.

Engineers remember design patterns.

Chess masters remember board positions.

Pattern Thinkers remember Pattern Families.

Classification dramatically reduces cognitive effort.

Instead of learning:

500 individual situations,

you learn:

20 reusable pattern families.


7.5 Classification Is Knowledge Compression

One of the recurring themes of this book is:

Knowledge becomes more powerful as it becomes more organized.

Taxonomy is another form of Pattern Compression.

Consider biology.

Millions of organisms become:

Kingdom

↓

Phylum

↓

Class

↓

Order

↓

Family

↓

Genus

↓

Species

Complexity becomes manageable.

Pattern Thinking follows the same principle.

Thousands of recurring situations become a manageable Pattern Library.


7.6 The Pattern Taxonomy Framework (PTF)

This book introduces the Pattern Taxonomy Framework (PTF).

Observe

Apply


Each stage builds on earlier chapters.


Stage 1 — Observe

Collect recurring examples.


Stage 2 — Recognize

Identify genuine patterns.


Stage 3 — Represent

Represent each pattern consistently.


Stage 4 — Map

Understand relationships among patterns.


Stage 5 — Classify

Group similar patterns together.

This creates Pattern Families.


Stage 6 — Compare

Study similarities and differences.

Comparison improves understanding.


Stage 7 — Apply

Transfer patterns across different domains.

Application is the purpose of Pattern Taxonomy.


7.7 Dimensions of Classification

Unlike traditional classification,

patterns can belong to several categories simultaneously.

This book recommends classifying every pattern using multiple dimensions.


Structure

How is it organized?

Examples:

Hierarchy

Network

Matrix

Layer

Tree


Behaviour

How does it behave?

Examples:

Growth

Cycle

Flow

Decay

Oscillation

Feedback


Function

What purpose does it serve?

Examples:

Learning

Decision Making

Control

Communication

Optimization

Adaptation


Scale

At what level does it operate?

Examples:

Individual

Team

Organization

Society

Global


Stability

How often does it change?

Examples:

Stable

Adaptive

Dynamic

Emergent


Abstraction

How general is the pattern?

Examples:

Specific

Professional

Universal

Each dimension reveals a different aspect of the same pattern.


7.8 Humans and AI Classify Differently

Humans naturally organize knowledge into concepts and categories.

AI learns statistical relationships across vast datasets.

Both ultimately create internal structures for organizing knowledge.

Consider medicine.

A physician classifies diseases using:

  • anatomy

  • physiology

  • pathology

  • clinical experience

An AI model identifies patterns from:

  • clinical records

  • imaging

  • laboratory results

  • statistical associations

The methods differ.

The objective is the same:

Organize knowledge to improve reasoning.

Pattern Taxonomy provides a common language that both humans and AI can use effectively.


Worked Example 1

Classifying Patterns in Nature

Observe:

  • River

  • Wind

  • Blood

  • Electricity

  • Internet traffic

Classification

Example

Pattern Family

River

Flow

Wind

Flow

Blood

Flow

Electricity

Flow

Internet Traffic

Flow

Five different subjects.

One universal pattern.

Taxonomy reveals the underlying unity.


Worked Example 2

Classifying Patterns in Business

Observe:

  • Customer referrals

  • Employee mentoring

  • Product improvement

  • Social media engagement

Classification

Example

Pattern Family

Customer referrals

Growth

Employee mentoring

Learning

Product improvement

Feedback

Social media engagement

Network

Instead of memorizing isolated business cases,

professionals build Pattern Libraries.


7.9 Universal Patterns versus Domain Patterns

Pattern Thinking distinguishes between two major categories.


Universal Patterns

Appear almost everywhere.

Examples:

  • Flow

  • Feedback

  • Growth

  • Cycle

  • Hierarchy

  • Queue

  • Balance

  • Network


Domain-Specific Patterns

Unique to particular disciplines.

Examples

Medicine

Clinical diagnosis

Engineering

Load distribution

Software

Design patterns

Finance

Compound interest

Education

Curriculum design

Experts combine universal patterns with domain-specific patterns.


7.10 The First Rule of Pattern Taxonomy

The first principle of Pattern Taxonomy is:

Classify by the underlying pattern, not by the subject in which it appears.

A river and a supply chain belong together because both express Flow.

A thermostat and classroom assessment belong together because both express Feedback.

Classification based on subjects hides similarities.

Classification based on patterns reveals transferable knowledge.

This is the foundation of interdisciplinary thinking.

Professional Power Prompt

Analyze the following domain and identify all recurring patterns. Classify each pattern according to its structure, behaviour, function, scale, stability, and level of abstraction. Distinguish between universal patterns and domain-specific patterns, and explain how each pattern can be transferred to another discipline.


Practical Exercise

Choose a familiar domain such as healthcare, software engineering, education, manufacturing, finance, or sports.

  1. Identify 15 recurring patterns.

  2. Classify each pattern according to:

    • Structure

    • Behaviour

    • Function

    • Scale

    • Stability

    • Abstraction

  3. Separate the patterns into Universal and Domain-Specific categories.

  4. Select one universal pattern and identify five different domains where it appears.

Reflect on how classification helped you discover similarities that were not obvious when studying the domain alone.


Looking Ahead

In Part 2, you will build a complete Pattern Taxonomy, learning how to organize patterns into families, hierarchies, and multidimensional classification systems. You will also explore the Pattern Classification Cube, compare alternative taxonomies, and discover how experts create reusable Pattern Libraries that accelerate learning and enhance AI-assisted reasoning.

"Recognition discovers patterns. Taxonomy organizes them. Once patterns are classified, knowledge becomes searchable, reusable, and transferable across every discipline."


Pattern Thinking: A Practical Grammar of Intelligence

Chapter 7

Classifying the World's Patterns

Part 2 — Building a Pattern Taxonomy


7.11 From Observation to Organization

Earlier chapters taught us how to discover patterns.

Now we must organize them.

Without organization,

Pattern Thinking remains a collection of interesting observations.

With organization,

it becomes a practical system for learning, teaching, problem-solving, and AI collaboration.

This transition is the difference between collecting patterns and building a Pattern Library.


7.12 The Pattern Classification Cube (PCC)

One of the unique contributions of this book is the Pattern Classification Cube (PCC).

Unlike traditional taxonomies, a pattern is not placed into just one category.

Instead, it is classified simultaneously across three independent dimensions.

                Function

                    ▲

                    │

                    │

                    │

                    ●────────► Structure

                   /

                  /

                 /

          Behaviour


Every pattern has:

  • Structure (How it is organized)

  • Behaviour (How it changes over time)

  • Function (Why it exists)

Thinking in three dimensions produces a richer understanding than a single-label classification.


7.13 Classifying by Structure

Structural classification focuses on how a pattern is arranged.

Common Structural Pattern Families

Structural Pattern

Description

Hierarchy

Levels organized from top to bottom

Network

Interconnected nodes

Chain

Sequential links

Tree

Branching relationships

Matrix

Multiple intersecting dimensions

Layer

Stacked levels with defined roles

Hub-and-Spoke

Central node connected to many others

Modular

Independent units working together


Example

A hospital has:

  • Organizational hierarchy

  • Referral network

  • Patient care chain

  • Layered information systems

Each reveals a different structural pattern.


7.14 Classifying by Behaviour

Behaviour describes how a pattern changes over time.

Behavioural Pattern Families

Behaviour Pattern

Description

Flow

Continuous movement

Growth

Progressive expansion

Decline

Progressive reduction

Cycle

Repeating stages

Feedback

Self-correction or reinforcement

Oscillation

Alternating states

Adaptation

Response to changing conditions

Emergence

New behaviour arising from interactions


Example

A business experiences:

  • Revenue growth

  • Seasonal cycles

  • Customer feedback

  • Cash flow

These are behavioural rather than structural patterns.


7.15 Classifying by Function

Function explains why a pattern exists.

Functional Pattern Families

Functional Pattern

Purpose

Communication

Exchange information

Decision

Select actions

Learning

Acquire knowledge

Control

Maintain stability

Optimization

Improve performance

Protection

Reduce risk

Coordination

Synchronize activities

Innovation

Generate new possibilities


Example

Software systems include patterns for:

  • Authentication

  • Authorization

  • Error recovery

  • Logging

  • Monitoring

Each exists for a different functional purpose.


7.16 Multi-Dimensional Classification

Most real-world patterns belong to several categories simultaneously.

Consider Feedback.

Dimension

Classification

Structure

Network

Behaviour

Feedback

Function

Learning and Control

Feedback is therefore not just a behavioural pattern.

It also has a structural organization and a functional purpose.

This multidimensional approach avoids oversimplification.


7.17 Pattern Families

Closely related patterns form Pattern Families.

A Pattern Family contains patterns that share fundamental characteristics while differing in specific implementations.

Example: Flow Family

  • River Flow

  • Blood Circulation

  • Airflow

  • Traffic Flow

  • Data Flow

  • Supply Chain Flow

  • Workflow

  • Cash Flow

The implementation changes.

The underlying pattern remains the same.


7.18 Pattern Hierarchies

Patterns can also be organized hierarchically.

This book proposes the following hierarchy.

Universal Patterns

        │

        ▼

Pattern Families

        │

        ▼

Pattern Types

        │

        ▼

Pattern Variants

Weekly Quiz Review


Each level becomes increasingly specific.


7.19 Universal and Specialized Taxonomies

A mature Pattern Library combines two complementary taxonomies.

Universal Taxonomy

Contains patterns found across nearly every discipline.

Examples

  • Flow

  • Feedback

  • Growth

  • Balance

  • Queue

  • Hierarchy

  • Network

  • Cycle


Specialized Taxonomy

Contains discipline-specific patterns.

Examples

Medicine

  • Disease progression

  • Differential diagnosis

  • Homeostasis

Engineering

  • Load distribution

  • Failure modes

  • Stress concentration

Software

  • Observer Pattern

  • Factory Pattern

  • Event-driven Architecture

Finance

  • Compound interest

  • Market correction

  • Portfolio diversification

Experts move fluently between universal and specialized taxonomies.


7.20 Cross-Domain Pattern Transfer

The greatest value of taxonomy is transfer.

Once a pattern is understood in one field, it can often be applied elsewhere.

Example: Queue Pattern

Healthcare

Patients waiting

↓

Retail

Customers waiting

↓

Computer Networks

Packets waiting

↓

Manufacturing

Jobs waiting

↓

Artificial Intelligence

Tasks waiting

Although the subjects differ, the Queue Pattern behaves similarly across domains.

Pattern Taxonomy makes this transfer visible.

Pattern Taxonomy makes AI workflows easier to analyze, compare, and improve.


7.21 Building Your Own Pattern Library

A Pattern Library is a personal or organizational collection of reusable patterns.

Each pattern entry should include:

Field

Description

Pattern Name

Standardized title

Family

Pattern Family

Structure

Organizational form

Behaviour

Dynamic characteristics

Function

Primary purpose

Domains

Where it appears

Examples

Real-world instances

AI Applications

How AI uses the pattern

Related Patterns

Connected pattern families

Over time, this library becomes a reusable knowledge asset for both humans and AI systems.


7.22 The Second Rule of Pattern Taxonomy

The second principle of Pattern Taxonomy is:

Classify every pattern from multiple perspectives rather than assigning it a single label.

A Feedback Pattern is not only about behaviour.

It also has:

  • a structural organization,

  • a functional purpose,

  • relationships with other patterns,

  • and applications across many domains.

The richer the classification, the more reusable the knowledge.

Professional Power Prompt

Create a multidimensional taxonomy for the following domain. Classify every recurring pattern by structure, behaviour, function, scale, stability, and abstraction. Group related patterns into Pattern Families, identify universal and domain-specific patterns, and build a reusable Pattern Library. Finally, recommend how this taxonomy could improve AI prompting, retrieval, and decision-making.


Practical Exercise

Choose a domain such as healthcare, software engineering, finance, education, manufacturing, agriculture, or sports.

  1. List 20 recurring patterns.

  2. Classify each using the Pattern Classification Cube:

    • Structure

    • Behaviour

    • Function

  3. Organize them into Pattern Families.

  4. Build a Pattern Hierarchy from universal patterns to real-world examples.

  5. Identify five universal patterns that also appear in at least three unrelated disciplines.

  6. Create a one-page Pattern Library and ask an AI assistant to suggest missing patterns or alternative classifications.

Reflect on how multidimensional classification revealed connections that would have been hidden in a single-category taxonomy.


Looking Ahead

In Part 3, you will explore Pattern Libraries in depth. You will learn how experts build reusable collections of patterns, organize them into hierarchies and inheritance structures, distinguish between universal and specialized libraries, and use them as powerful tools for accelerated learning, innovation, and AI-assisted reasoning.

"A taxonomy organizes patterns. A Pattern Library preserves them. Together, they transform scattered experience into reusable intelligence."

Pattern Thinking: A Practical Grammar of Intelligence

Chapter 7

Pattern Taxonomy

Classifying the World's Patterns

Part 3 — Pattern Libraries and Reusable Intelligence


7.23 From Classification to Libraries

A taxonomy answers:

"Where does this pattern belong?"

A Pattern Library answers:

"How can I use this pattern again?"

This distinction is important.

Taxonomy organizes knowledge.

A Pattern Library preserves, expands, and makes that knowledge reusable.

Experts do not repeatedly rediscover patterns.

They build libraries of reusable intelligence.


7.24 What Is a Pattern Library?

Definition

A Pattern Library is an organized collection of reusable patterns, their relationships, examples, applications, and variations that enables faster learning, problem-solving, innovation, and AI collaboration.

A Pattern Library is to Pattern Thinking what a dictionary is to language.

It becomes a shared vocabulary for reasoning.


Example

An architect rarely designs every building from first principles.

Instead, they reuse patterns such as:

  • Courtyard

  • Corridor

  • Atrium

  • Modular Room

  • Open Space

  • Service Core

Similarly, an experienced AI practitioner reuses prompt patterns, reasoning patterns, workflow patterns, and decision patterns rather than inventing them repeatedly.


7.25 Why Experts Build Pattern Libraries

One defining characteristic of expertise is not possessing more facts.

It is possessing better organized patterns.

Consider the following professionals.

Professional

Pattern Library

Doctor

Disease and treatment patterns

Software Engineer

Design and architecture patterns

Chess Grandmaster

Board position patterns

Musician

Harmonic and rhythmic patterns

Investor

Market behaviour patterns

Teacher

Learning and assessment patterns

Experts recognize situations quickly because they compare them against an internal Pattern Library.


7.26 Components of a Pattern Library

Every reusable pattern should contain consistent information.

This book recommends the following template.

Component

Purpose

Pattern Name

Standard identifier

Pattern Family

Classification category

Definition

Meaning of the pattern

Structure

Organizational form

Behaviour

Dynamic characteristics

Function

Purpose served

Examples

Real-world instances

Related Patterns

Connected patterns

Anti-Patterns

Common failures

AI Applications

How AI uses the pattern

Transfer Opportunities

Other domains where it applies

Consistency makes libraries searchable and reusable.


7.27 Pattern Families and Pattern Inheritance

Patterns often inherit characteristics from broader Pattern Families.

This relationship resembles biological inheritance.

Universal Pattern


        │


        ▼


Flow


        │


────────┼────────


        │


Water Flow


Data Flow


Traffic Flow


Supply Flow


Blood Flow


Workflow


Cash Flow


Every specialized pattern inherits the essential properties of Flow while adapting to its own domain.

Inheritance accelerates learning because understanding the parent pattern makes the variants easier to understand.


7.28 Pattern Variants

No pattern appears exactly the same everywhere.

Instead, patterns adapt to their environments.

Example: Feedback Pattern

Education

Teacher → Student → Improvement

Healthcare

Diagnosis → Treatment → Recovery

Software

Testing → Bug Fix → Deployment

Business

Customer Review → Product Improvement

Artificial Intelligence

Human Feedback → Model Improvement

The implementation changes.

The underlying logic remains constant.


7.29 Universal versus Specialized Pattern Libraries

Pattern Libraries exist at two complementary levels.


Universal Library

Contains reusable patterns applicable across many disciplines.

Examples

  • Flow

  • Growth

  • Balance

  • Feedback

  • Hierarchy

  • Queue

  • Network

  • Cycle

  • Constraint

  • Decision

These patterns enable interdisciplinary thinking.


Specialized Library

Contains patterns unique to particular domains.

Medicine

  • Clinical diagnosis

  • Differential diagnosis

  • Homeostasis

  • Disease progression

Software Engineering

  • Observer Pattern

  • Singleton Pattern

  • Event-driven Architecture

  • Microservices

Finance

  • Compound growth

  • Diversification

  • Arbitrage

  • Risk hedging

Education

  • Spaced repetition

  • Formative assessment

  • Scaffolding

  • Retrieval practice

Professionals combine universal libraries with specialized libraries to solve complex problems.


7.30 Pattern Reuse

The true value of a Pattern Library lies in reuse.

Instead of solving every problem from scratch,

we ask:

Which known pattern resembles this situation?

Example

A hospital reduces patient waiting time using Queue Management.

A software company uses the same Queue Pattern for server requests.

An airport uses the same Queue Pattern for passengers.

Different domains.

Same reusable intelligence.


7.31 Pattern Evolution

Pattern Libraries are living systems.

Patterns evolve as technology, society, and knowledge evolve.

Consider communication.

Earlier Library

Letter

↓

Telephone

↓

Email

Modern Library

Messaging

↓

Video Meetings

↓

AI Assistants

↓

Autonomous Agents

The family remains.

The implementations evolve.

Pattern Libraries therefore require continuous refinement.


7.32 Pattern Anti-Patterns

Every library should include Anti-Patterns.

Definition

An Anti-Pattern is a recurring solution that appears useful but consistently produces undesirable outcomes.

Learning what not to do is as valuable as learning successful patterns.


Examples

Software

Hard-coded configuration

Business

Micromanagement

Healthcare

Treating symptoms while ignoring root causes

Education

Teaching only for examinations

Artificial Intelligence

Prompting without sufficient context

Including Anti-Patterns makes a Pattern Library more practical.


7.33 Pattern Discovery Loop

Pattern Libraries continuously expand.

This book proposes the Pattern Discovery Loop (PDL).

7.34 AI and Pattern Libraries

Large Language Models perform better when supplied with structured Pattern Libraries rather than isolated facts.

Compare these prompts.


Prompt A

Explain project management.


Prompt B

Pattern Library


Planning


Decision


Communication


Feedback


Risk


Iteration


Learning


Dependencies


Leverage Points


Apply these patterns to software engineering.


Prompt B provides an organized library.

AI retrieves relationships rather than disconnected information.

Pattern Libraries therefore improve:

  • prompting

  • retrieval

  • reasoning

  • planning

  • decision support

  • knowledge transfer


7.35 The Third Rule of Pattern Taxonomy

The third principle of Pattern Taxonomy is:

Build libraries of reusable patterns rather than collecting isolated examples.

Facts become outdated.

Individual examples fade.

Reusable patterns continue to generate value across domains, professions, and technologies.

A good Pattern Library compounds in usefulness over time.

  4. Add at least five Anti-Patterns.

  5. Identify three universal patterns that also appear outside your profession.

  6. Ask an AI assistant to review your library and suggest additional patterns, relationships, or missing categories.

Reflect on how a structured Pattern Library differs from a collection of notes or examples, and how it can accelerate expertise.


Looking Ahead

In Part 4, you will consolidate your understanding of Pattern Taxonomy through chapter summaries, review questions, Pattern Taxonomy checklists, AI laboratories, professional applications, and a complete framework for building and maintaining your own lifelong Pattern Library.

"Taxonomy organizes knowledge. Pattern Libraries preserve it. Reuse transforms it into expertise."

7.36 Chapter Summary

Throughout this chapter, we have moved from discovering patterns to organizing them into a coherent knowledge system.

Pattern Taxonomy transforms isolated observations into structured intelligence.

We learned that:

  • Patterns are easier to understand when classified.

  • Every pattern can be viewed from multiple dimensions.

  • Pattern Families simplify learning.

  • Pattern Libraries preserve reusable intelligence.

  • Universal patterns enable cross-domain thinking.

  • AI performs better when knowledge is organized into structured Pattern Libraries.

The central idea of this chapter is:

Classification transforms scattered patterns into reusable intelligence.

7.44 Answers and Hints

Question 1

Pattern Taxonomy is the systematic classification of recurring patterns according to characteristics such as structure, behaviour, function, scale, and abstraction, making knowledge easier to organize, compare, and reuse.


Question 4

Universal patterns appear across many domains (e.g., Flow, Feedback, Growth), whereas domain-specific patterns are unique to a particular field (e.g., Differential Diagnosis in medicine or Observer Pattern in software engineering).


Question 6

A Pattern Library is an organized collection of reusable patterns, their relationships, examples, applications, and variations, enabling faster learning and problem-solving.


Question 9

An Anti-Pattern is a recurring but ineffective approach that appears reasonable yet consistently produces poor outcomes. Recognizing Anti-Patterns helps avoid repeated mistakes.


Question 10

The Pattern Discovery Loop describes the continuous cycle of observing, recognizing, classifying, storing, reusing, refining, and discovering new patterns, allowing Pattern Libraries to evolve over time.


Chapter Takeaways

By completing this chapter, you have developed another foundational capability in Pattern Thinking.

You can now:

  • Organize patterns into systematic taxonomies.

  • Build Pattern Families and Pattern Libraries.

  • Classify patterns using multiple dimensions.

  • Distinguish universal and domain-specific patterns.

  • Identify Pattern Variants and Anti-Patterns.

  • Build reusable knowledge assets for humans and AI.

  • Improve AI collaboration through structured Pattern Libraries.

Pattern Taxonomy changes the way knowledge is stored and accessed. Instead of remembering isolated facts or examples, you build an organized system of reusable intelligence that grows in value over time.

Pattern Taxonomy


These seven chapters establish the Core Foundations of Pattern Thinking:

  • Chapter 1 defined patterns as reusable units of understanding.

  • Chapter 2 explained the elements that make patterns identifiable.

  • Chapter 3 developed the discipline of observing patterns.

  • Chapter 4 focused on recognizing and validating genuine patterns.

  • Chapter 5 demonstrated how to represent patterns clearly.

  • Chapter 6 connected patterns into systems through Pattern Mapping.

  • Chapter 7 organized those systems into taxonomies and reusable Pattern Libraries.

Together, they move the reader from seeing patterns to building structured knowledge.


Looking Ahead

Chapter 8 — Pattern Language

Speaking and Thinking in Patterns

Individual patterns are like words.

Pattern Taxonomies are like dictionaries.

The next step is learning how to combine patterns into meaningful expressions.

In Chapter 8, you will explore Pattern Language—the grammar of patterns. You will learn how patterns combine to form sequences, systems, strategies, and solutions, enabling you to communicate, design, innovate, and collaborate with AI using a shared language of reusable intelligence.

"Taxonomy organizes patterns into a vocabulary. Pattern Language teaches us how to combine that vocabulary into fluent thought."
