What does peace actually mean?

We looked at how peace is defined across research, policy, and practice. We found three things every idea of peace has in common. The paper is peer-reviewed and available open access.

The question

There are hundreds of definitions of peace. Academics, governments, NGOs, and communities all use the word differently — and that creates real problems. Without shared language, organisations cannot compare their work, measure progress, or build on each other's results.

So we asked: is there anything all these different definitions have in common? Not to replace any of them, but to find the shared ground underneath.

Three things every idea of peace shares.

Across hundreds of definitions, these three elements appear without exception.

Social interaction

Peace is always about how people — or groups, or nations — interact with each other. It lives between us, not inside us.

Living beings

Peace involves beings who can feel and experience life. It is about creatures that matter to themselves.

Wellbeing

Peace points toward people being able to live well. It supports, enables, or creates the conditions for flourishing.

Reframing the Ontology of Peace Studies

Reagan, A.
Open Access

What this paper does

Published in a peer-reviewed journal in 2023, this paper examines what philosophers call the ontology of peace — what peace fundamentally is, beneath the differences in how it is defined. Using analysis across academic, policy, and practice traditions, it identifies three structural elements present in every definition, and shows why that matters for the field as a whole.

Relevant wherever you sit in the field.

This framework does not replace any existing approach to peace — it reveals what every approach already shares. The same way the IPCC gave climate science a shared conceptual anchor, and the SDGs gave development work common goals, this is designed to do something similar for peace. Here is what that changes for each part of the field.

Funders

Finally compare what you fund

When every organisation defines peace differently, evaluating and comparing them is nearly impossible. This framework gives a shared lens — so you can see how diverse grantees contribute to the same underlying problem and make more confident allocation decisions.

Peace organisations

Articulate your impact clearly

Whether you work on conflict resolution, community dialogue, or ecological restoration, this framework shows precisely how your approach connects to the foundations of peace — making it easier to explain your value to funders and find complementary partners.

Policymakers

Build agreements on shared ground

Peace processes often stall when parties hold incompatible ideas of what peace requires. This framework identifies conceptual common ground that persists across political, cultural, and institutional differences — a foundation for agreements that can hold.

A theory of change for the whole field.

Four steps. We are currently on steps one and two.

Step 1 — Build the foundation Happening now

Research what peace means across different definitions. Find the shared elements. Publish the findings for peer review. This step is complete and ongoing.

Step 2 — Help organisations use it Happening now

Work with peace organisations to connect their work to the shared framework and help them communicate their impact more clearly. This is where our workshops and consultancy come in.

Step 3 — Better coordination across the field

As more organisations use the shared framework, it becomes easier to see gaps and overlaps, and partnerships form more naturally. The more organisations join, the more useful it becomes for everyone.

Step 4 — Progress that compounds

With shared foundations in place, progress builds over time rather than starting over with each new project. Resources currently spent on duplicated work can go toward new ground instead.
