Beyond the Pleasure Principle, Death Drive

Freud didn't have a mature notion of the drive, perhaps it's because he didn't discover it until he was almost ready to expire. He was near 70 when he came up with the notion. So I feel like that's, I think you're right that there's a way in which he doesn't get to develop it as fully as he otherwise might. But this is the text in which he, he doesn't.
