"Insistence therefore emerges as a type of repetition, only a type, which is different every time, like the hops of the frog hopping." (Kartsaki, 2017)
Like the hops of a frog that are different every time but the same, insistence is a way of explaining repetition as a method of building upon the last, each iteration adding to that which came before. The frog travels.
