As you say, a million isolated seconds of suffering isn't as bad as a million consecutive seconds of suffering, because (among other things) of the knock-on effects of consecutivity (e.g. PTSD). Maybe it's only 10% as bad, or 1%, or .1%, or .0001%, or whatever. Sure, agreed, of course.

But the moral intuition being challenged by "shut up and multiply" isn't about that.

If everyone agreed that sure, N dust-specks was worse than 50 years of torture for some N, and we were merely haggling over the price, the thought experiment would not be interesting. That's why the thought experiment involves ridiculous numbers like 3^^^3 in the first place, so we can skip over all that.

When we're trying to make practical decisions about what suffering to alleviate, we care about N, and precision matters. At that point we have to do some serious real-world thinking and measuring and, y'know, work.

But what's challenging about "shut up and multiply" isn't the value of N, it's the existence of N. if we're starting out with a moral intuition that dust-specks and torture simply aren't commensurable, and therefore there is no value of N... well, then the work of calculating it is doomed before we start.

OK, I now understand the way the site works: If someone responds to your comment, it shows up in your mailbox like an e-mail. Sorry for getting that wrong with Vaniver ( i responded by private mail), and if I can fix it in a little while, I will (edit: and now I have). Now, to content:

Thanks for responding to me! I didn't feel like I should hijack the welcome thread for something I didn't know hadn't been thoroughly discussed elsewhere. So I tried to be succinct, and failed and ended up garbled.

First, 3^^^3 is WAY more than a googolplex ;-)
