Concepts have meaning only if we can point to objects to which they refer and to the rules by which they are assigned to these objects.85 In other words, for a concept to make sense you need an operational definition of it, one that describes how you would observe the concept in operation.
In Walter Isaacson's book "Einstein: His Life and Universe," he discusses the importance of operational definitions for concepts. He emphasizes that concepts gain significance only when they are linked to tangible objects or phenomena and the specific rules that connect them. This connection is essential for understanding and utilizing concepts in a meaningful way.
Isaacson argues that to truly grasp a concept, one must establish a clear framework that allows for observation and measurement. This operational definition enables individuals to see how the concept functions in practice, ultimately making it easier to apply and comprehend in various contexts.
