Heidegger and 'being right'

This morning I was reading Heidegger's thoughts on essence for my lesson on Being and Essence. It was only a summary, from the Historisches Worterbuch der Philosophie article on Wesen, but it was interesting all the same, the type of things the man can do with words and with language. Terribly evocative, his use of language. No wonder he is so attractive.

I was saying at the Lonergan Reading Group this afternoon: Gadamer corrects Heidegger in significant ways, but without a doubt Heidegger is greater than Gadamer. One does not have to get it all right to be a great philosopher, and one does not always have to be the greatest philosopher in order to be right! Many great philosophers have been wrong in very significant ways, and yet they have contributed significantly to the unfolding of thought and the self-discovery of the human being.

And I guess thoughts on right and wrong might not even make sense to a Heideggerean. But.
