The concept that there are concepts cannot be verified in any way other than conceptually.    


The argument that everything is conceptual is thought going around in circles.     


Although this argument is popular among those who think they have some kind of advaita understanding, 
it only shows that thought has displayed an example of  circular reasoning, through the sentient biological object in question..  
  
If energy ceases in going around in circles, ideas about ideas vanish.   

 Including that very idea.
