" want to live until I make a conscious decision to die. I don't think I'll choose that that for a while, and I don't think you would either.
Is currently my favorite way of arguing that dying is bad. It starts off with something really obvious, and then a pretty inferentially close follow-up that extends it into not dying.
It starts off with a tautology
Not technically.
(Comment syntax tip: Use '>' at the start of a paragraph you wish to quote and it'll look all spiffy.)
Terminal values and preferences are not rational or irrational. They simply are your preferences. I want a pizza. If I get a pizza, that won't make me consent to get shot. I still want a pizza. There are a virtually infinite number of me that DO have a pizza. I still want a pizza. The pizza from a certain point of view won't exist, and neither will I, by the time I get to eat some of it. I still want a pizza, damn it.
Of course, if you think all of that is irrational, then by all means don't order the pizza. More for me."
