How to trace the history of a concept.

01Why know the history of a concept?

When a concept moves from one discipline to another, it keeps part of its original meaning and loses another part. Resilience, for example, described the strength of materials long before it reached psychology and, from there, the school. Anyone who knows that journey understands why the term is used today in ways that clash with each other.

Tracing its history has three advantages:

• You define it precisely, because you know which meaning you use and which you set aside.
• You avoid false attributions, the quotations that pass from one bibliography to the next without anyone checking them.
• You teach it better, because a concept with a history is easier to understand and remember than an isolated definition.

1. Enter the concept
2. Trace its journey
3. Read the key moments
4. Look at the jumps between disciplines
5. Review myths and tensions

02How to use Genealogy of an Idea in 5 steps

1. Enter the concept

   Type a single word or phrase, such as resilience or human capital. The tool works with concepts, not with long texts.

2. Trace its journey

   Press Trace. In about a minute you will see the concept’s biography, from its origin to its current use.

3. Read the key moments

   In The journey, each moment shows what the concept meant then and what changed. Filled dots mark ruptures, that is, the moments when its meaning took a turn.

4. Look at the jumps between disciplines

   The section When it jumped disciplines shows what happened to the concept when it was adopted by fields that needed it for something else.

5. Review myths and tensions

   Finish with Common misconceptions, which gathers mistaken attributions, and Living tensions today, where you will see the meanings that coexist and clash in current use.

A definition tells you what a word means. Its history explains why we use it the way we do.

03Example: the journey of “resilience”

A teacher is preparing a unit on emotional wellbeing and wants to use the term rigorously. This is how he could make use of what the tool finds:

What appears	Example	How to use it in class
A point of origin	In nineteenth-century engineering, a material’s capacity to absorb a blow and recover its shape.	Open the unit with that physical image, which is easy to picture.
A jump between disciplines	Ecology adopts it in the 1970s to describe systems that withstand disturbances.	Show that the term had already changed before it reached psychology.
A common misconception	That being resilient means not suffering in the face of adversity.	Make clear that it describes recovery, not the absence of pain.
A current tension	A trait of the person, or the result of a supportive environment.	Hold a class debate with both positions.

04Tips to get the most out of it

• Choose concepts you take for granted. The most common terms in your discipline are often the ones with the most interesting history.
• Check before you cite. Dates and attributions are reconstructions. Use them as leads and verify them in primary sources before using them in academic work.
• Pay attention to the ruptures. Filled dots mark where the meaning of the concept changed, and that is usually where you will find what is most useful for a lesson or a theoretical framework.
• Use it with your students. Ask them to compare the dictionary definition with the concept’s genealogy and to explain how they differ.
