&gt; The thing is, the definition of a concept, is the axiom that it exists outside of human understanding.<p>I don&#x27;t agree with that definition of a concept.<p>Idea = mental representation of an object, or a set of objects and their interactions.<p>Concept = generalization of an idea.<p>wherein &#x27;mental&#x27; justifiably implicates the working of a brain. It is very much tied to what we call brain understanding. Sorry for taking this discussion to the definition of words.
