If we take action now to mitigate global climate change, it might make life a little worse for people now and in the near future, but it will make life much better for people further in the future. Suppose, for whatever reason, we do nothing.
Since future people will have much worse lives, it seems that we owe it to future generations to do something now. But if we do things differently now, it will have the side-effect of bringing into existence different people than those that would have been brought into existence if we did nothing.
That might sound strange. But if you procreate in October instead of December, if you go build windmills and delay going to college and so meet someone else or the same person at a different time, if you do almost anything differently the children you have will not be the ones you would have had.
If we do nothing, do people in the future have a right to complain that we made their lives much worse? Here’s the odd bit. The future people who have better lives because we acted, and the ones who have worse lives because we didn’t, are not the same people. As long as your life is worth living, you can’t complain about things done before you existed that helped bring you into existence, because if any of them had been different, very likely you would not exist. Again, as long as your life is worth living the choice is not between you having a better or worse life, it’s a choice between existing and not existing.
That seems crazy, right? Philosophers call it the nonidentity problem. Read more »



As a consequential Supreme Court term gets underway, with potentially large consequences for women’s autonomy and health, it’s worth thinking about the ways in which judges do or do not consider the real world consequences of their decisions.


I knew that Cambridge was by the river Cam, but the first day when I looked for it I could not find it. From the map I knew that on my way to the Economics Department I had to cross it, I stopped and looked around but I could not see anything like a river. Then I asked a passerby, and he pointed to what I had thought was a small ditch or a canal. It was difficult to take it as a river, as in India I was used to much bigger rivers. Over time, however, I saw the serene beauty of this mini-river, with its placid water by the weeping willows, the swans, gliding boats and all.
The well-known counterintuitive Monty Hall problem continues to baffle people if the emails I receive are any indication. A meta-problem is to understand why so many people are unconvinced by the various solutions. Sometimes people even cite the large number of the unconvinced as proof that the solution is a matter of real controversy, just as in politics an inconvenient fact, such as the ubiquity of Covid-19, is obscured by fake controversies.
It had been a long time since I thought about lawns. I don’t mean in a grand philosophical sense, or the stoned contemplation of a single blade of grass. I mean thought about them at all. Before moving to Mississippi we had lived in Vancouver for 13 years, where we felt lucky to have a place to store our toothbrushes and maybe an extra pair of slacks; we really hit the jackpot when we acquired a postage-stamp-sized balcony on which we could murder tomato plants. Actual yards were out of the question for anyone who hadn’t bought a house on the west end of town 30 years ago; by the time we moved to Vancouver in 2006 as a tenure-track assistant professor and a trailing-spouse adjunct, it was already clear that we would never own a lawn.

What is it to be twenty? Forty? Sixty? Eighty? These points that mark the four quarters of a life — fifths if you’re lucky, larger portions if you’re not.
