“I often think to myself, ‘Could I justify my life now to my 15-year-old self?’ And if the answer is no, then I’m a bit like, ‘Oh, what are you doing? You’re not living up to what earlier Will would’ve wanted for present Will.’”

— Will MacAskill

“I give away most of my income, which is a very unusual thing to do. And you might think, oh, that’s a sacrifice that’s making my life worse, but actually I find it kind of empowering because I am making an autonomous decision. I am not merely following the dictates of what social convention is telling me to do, but I’m reasoning about things from first principles and then making a decision that’s genuinely, authentically mine.”
— Will MacAskill

“In the last podcast, we talked a lot about global health and development and what’s the difference you can make? Well, if you are a middle-class member of a rich country, it’s on the order of saving dozens, hundreds, maybe even thousands of lives over the course of your life, if you put your mind to it. That’s huge. Now, we’re talking about existential risks and the long-term future of humanity. What’s the difference you can make? You can play a part in being pivotal in putting humanity onto a better trajectory for, not just centuries, but for thousands, millions, or even billions of years.”

“The amount of good that you can do is truly enormous. You can have cosmic significance, and that’s pretty inspiring.”
— Will MacAskill

“When you think about the difference you can make rather than just focusing on the magnitude of the problems, I think there’s every reason for optimism.”
— Will MacAskill

“Even just the progress we’ve made over the last few hundred years, people today have far, far better lives. If you extrapolate that out just a few hundred years more, let alone thousands of years, then there’s at least a good chance that we could have a future where everyone lives, not just as well as the best people alive today, but maybe tens, hundreds, thousands of times better.”
— Will MacAskill

“One thing I think that a lot of people find motivating is this thought that you’re part of this grand project, much, much grander than yourself, of trying to build a good and flourishing society over the course of not just centuries, but thousands of years, and that’s one way in which our lives have meaning.”
— Will MacAskill

“We face truly enormous challenges in our life. Many of these challenges are very scary. They can be overwhelming. They can be intimidating. But I really believe that each of us individually can make an enormous difference to these problems. We really can significantly help as part of a wider community to putting humanity onto a better path. And if we do, then the future really could be long and absolutely flourishing. And your great-great-grandkids will thank you.”
