I found this today during a search for my high school diaries and journals (hoping to participate in a "Get Mortified" event, but more on that aspiration later.....) yep, and I found this little scribbled note that I copied out of The Doomsday Dictionary, probably whilst I was listening to the Smiths or something:
"Thanatos (also, death instinct)-- One of two primal instincts attributed to man, the other being Eros. The function of Thanatos is to restore higher organic organization to a simpler, pre-vital state. In this, Thanatos is expressing a tendency evident elsewhere in nature for organization to run down into a greater simplicity.
The laws that regulate the compromise are obscure."

I think I left something out of the full entry, but this is all that I selected. I still love the final sentence: "The laws that regulate the compromise are obscure."
