reification

Reification is when you think of or treat something abstract as a physical thing.

Reification is a complex idea for when you treat something immaterial — like happiness, fear, or evil — as a material thing. This can be a way of making something concrete and easier to understand, like how a wedding ring is the reification of a couple's love. However, reification is often considered a sign that someone is thinking illogically. For example, if you think of justice as something physical, you're confusing ideas and things, which can lead to problems.
