Andrew Sullivan’s most impactful work came in the shadow of death.

Tyler Cowen declared Sullivan the generation’s most impactful public intellectual. Sullivan was hugely influential in the fight for gay marriage, as a thoughtful conservative advocate of gay marriage who was himself gay. He also pioneered the early art of blogging, with his early work leaving an indelible mark on how the craft developed. I’ve been grateful to have Sullivan occasionally link to my blog and I consider him one of the foremost public intellectuals of today.

A lot of Sullivan’s most influential work came when he believed he would soon die. He was diagnosed with HIV in the days when it was a death sentence. He thought he would die young, in his 30s, and wanted to leave some mark on the world before he was taken from it. He wanted to make the case for people like him being afforded equal rights in the few years he had left. It is an amazing miracle that treatment for HIV was developed, so that millions of people like Andrew didn’t have to die.

There’s an expression “live every day as if it’s your last.” Now, obviously, you shouldn’t do that. You should save for retirement. But it’s worth giving some serious thought to the question of what kind of legacy you want to leave. You should live some days as if they were your last. If you died tomorrow, what kind of impact would you want to have had on the world? Would you have done all you wished?

I don’t think that how you’d behave if this day was the last is the only question that you should think about. But it’s at least among the questions you should consider, upon occasion. You should think about whether you conducted yourself honorably in interpersonal relationships. You should think about who you wished you’d said you loved more often, whether there are people you love but to whom you haven’t made that adequately clear.

If I had another year on Earth, what would I want to achieve? I’d want to keep writing. My guess is I’d write more about the things I think are most important. I’d spend more time talking about the big picture on important topics, less on frivolous culture war issues.

I’d talk more about factory farming. I want, by the end of my life, to have done something to combat the torture farms that cage and torment on an industrial scale—where poor, innocent, defenseless animals are mutilated, where open wounds fester, where babies are ground up, where lung problems develop because the animals live in feces and filth, where they mostly can’t walk, where they are genetically engineered to be in constant pain, and so on. If hell lives on Earth today, it lives in the factory farms.

I’d like to do more to stop wild animals from suffering in hideous numbers. These poor innocent animals have no voice, and almost no one cares much when they starve and die. But I care, and I hope to do what I can to make the world care. The deer in the forest, even the mayfly who starves, deserves better than the near-total neglect of the present.

I’d want to do more to ensure that the world lives on, if I cannot. That the far future is as glorious as it can be—full of people with experiences so good that they regard those of us alive today with a mixture of pity and horror. Where their lives are so good, that they cringe thinking about what even the best lives in the 21st century were like. There’s so much that’s been done and so much more to do.

I’d like to do more to prevent people from dying. It’s quite easy to prevent people from dying. It costs just a few thousand dollars to prevent one extra person from being ripped from the world. When I imagine potential incoming death, and how awful that would be, and when I think about how awful it was when my extended family members died, it motivates me to do more to make sure others don’t have to endure such a fate. We all ought to do more to prevent this scourge, to the extent we can.

The Giving What We Can people tell me I’ve convinced about 30 people to give 10% of their income to effective charities. Each of these pledges return about $50,000 in counterfactual revenue. If those numbers are to be believed, that will save 300 lives. I hope with each passing day to make effective charitable giving more and more popular, so that the number of Giving What We Can pledgers isn’t only 10,000, but instead hundreds of thousands or millions of people take the pledge.

If I were to die tomorrow, in driving this, I would think I’d achieved something important. If you give your money to effective charities, you can know that whenever it is you leave Earth, there will be more people in it because of you. If you give 10% of your income to effective charities, and earn about the U.S. median, you can save about a life every year.

And, of course, I’d want to do what I could in my remaining months to save the shrimp—the shrimp who are tortured by the hundreds of billions because we enjoy how they taste when they die. The shrimp who can be helped by the thousands with a single dollar, who die alone without any thought paid to their pain.

Those without a voice, without any advocates, have their interests neglected to an enormous degree. There is almost no limit to the harm people will cause via their actions, so long as the victims aren’t salient, and no limit to how little effort one will expend to provide benefits to nameless, faceless, and far-away victims. This is where the moral low-hanging fruit lies.

You should live the kind of life where if you were given a terminal cancer diagnosis, you’d feel like you’d achieved something of note. That there was some important respect in which the world was better because of you. Don’t merely aimlessly float by—achieve something meaningful. And love, through your actions, all those you love in your heart, unfailingly, till the end.
