What Heidegger "says" being authentic is.

My feeling on what Heidegger says is authentic is not only speaking, but being genuine in your speaking. A man can say a lot without ever saying anything, while another man can say nothing; and can say more that the man who said a lot. Saying that someone said some may or may not be what they actually said. I started out the paragraph saying that “Heidegger says is authentic.” But that isn’t the only thing that makes language authentic we must also listen, and listen well.
