The Beginning of Infinity: The Transformative Power of Explanations

Understanding David Deutsch’s book The Beginning of Infinity will not only provide you with the best explanation (we have so far) of epistemology (theory of knowledge), but it will also provide you with a lens through which to view the world.

Deutsch provides us with a worldview that is extremely valuable in understanding the truth, which of course, should be the guiding principle when it comes to figuring out reality.

Some would even view Deutsch’s book as “self-help” since it can help you realize your unique ability to explain, be creative, spread ideas, criticize theories, and think for yourself. If nothing else, you will walk away a more optimistic and positive individual after reading the book.

But beyond providing you with this worldview, Deutsch’s book is a window into understanding human creativity and the differences in culture that exist across societies. In fact, the book can also help in everyday affairs such as running your business or your life for that matter.

Now that I’ve provided you with a sufficient overview of the book, let’s dive into the crux of Deutsch’s theory of knowledge.

The centerpiece argument of Deutsch’s book focuses on good explanations. You may be wondering: what’s so special about good explanations? I’ll attempt to answer that and lay out Deutsch’s theory in three parts.


Good explanations drive the world and allow us to make progress in society. Have you thought about how it is that we understand the world, reality, and truth? It is by coming up with explanations. The initial explanations we come up with do not have to be accurate. In fact, they rarely are. But that’s fine, because these explanations are then subject to criticism and undergo a process of error-correction, until we land upon the best explanation we have so far (of whatever we are trying to understand). In this manner, good explanations can also help us solve problems.

It is important to note that the explanations we land upon are not absolute truths. Anyone could come up with a better explanation that could debunk and falsify the existing explanation in place. Why is there no way of converging on an “absolute truth”?

Because humans are fallible. We make mistakes. Indeed, progress comes with mistakes. If we are not making mistakes, it could be a sign that we are going into stasis and that’s a scary place to be. But making mistakes is okay, because we can always strive to correct errors in our thinking and improve upon explanations. However, we cannot say with certainty that we have landed on the absolute truth precisely because we make errors. In fact, Deutsch lays out how even mathematics (which is typically considered the gold standard for absolute truth) can be falsified.

Because of this error-correcting mechanism and because problems lead to more problems, we are always improving upon our explanations. Deutsch makes a beautiful point when he says that science should be viewed as moving from one problem to another problem – this could remove us from thinking of explanations as absolute truths. This also implies something worth thinking about and pausing at: We are always at the beginning of infinite progress to be made! (Hence, the name of the book)


Okay, so I just went on this rant about why good explanations are important and how they drive progress in society. But what does Deutsch even mean by good explanations? Note that I’ve been using the phrase “good explanations” as opposed to simply “explanations.” I’ll state the obvious again which I discussed above already: It is, of course, possible to come up with bad explanations. Most of us are perhaps doing that on an everyday basis. But then, we error-correct to find good explanations from our bad explanations. How does one differentiate between a good and a bad explanation?

Good explanations are hard to vary, are testable, and falsifiable. Good explanations are also acts of creativity (they do not typically come from feeding in your questions into Google). Naval and Brett do a better job explaining good explanations than I would, so please read here and here. Of course, you could pick up Deutsch’s book itself 🙂


Firstly, it’s important to note that humans are unique in their ability to come up with explanations. All other animals are restricted to the information and explanations that reside in their genes. This is not trying to put other animals down, but rather showing how and why humans have contributed to all this progress in the world.

Explanations come from conjecture. They are bold guesses. Popular belief states that our theories and explanations come from observation and experience, but Karl Popper and Deutsch show how that cannot be. Explanations come from conjectures and they could come from any human. It is not the case that good explanations come from experts in the field or some form of authority figure.

Explanations are acts of human creativity. Even though we do not yet have a good explanation of where creativity comes from, it is what has enabled us to solve problems through conjecture and explanations, spread ideas and make progress. There is no limit to human creativity. Problems lead to more problems, and require human acts of creativity to be solved. Even though all problems are soluble, problems are also inevitable and we can solve them using acts of creativity. Which is to say that we can solve problems by coming up with good explanations.


We understand the world through explanations. Explanations come from conjecture and are acts of human creativity. Explanations are subject to criticism and undergo a process of error-correction and this is the process by which we land upon good explanations. Good explanations are hard to vary, testable, and falsifiable. However, these good explanations cannot be treated as absolute truths since humans are fallible. Explanations help us solve problems, but problems always lead to more problems, but also more progress to come. As a result, we are always at the beginning of infinity – of infinite knowledge and infinite progress.

There is a scenario where we don’t let infinite knowledge creation play out. It’s a scenario where we fall into stasis and are not optimistic and rational. Humans make choices and we can choose whether to fall into stasis or let infinite progress play out. Choosing infinite progress almost inherently requires an optimistic mindset and view of the future, and Deutsch delves into that.

Perhaps my most favorite parts of his book are his writings on optimism, dynamic societies, and the spread of ideas. I’ll write about that next time, so stay tuned! Until then, hope this post gets you pondering on good explanations and their transformative power.

International Day of Older Persons & Longevity Science to Reduce Suffering

October 1 was International Longevity Day or International Day of Older Persons and I want to use this occasion to raise awareness around an important issue that literally each and every one of us face or will face. It’s aging.

A lot of people ask me why I care so much about the aging field and longevity. Let me tell you.

This first picture is that of my beautiful grandparents when they were old but still functional.

This second picture is noticeably different – they look more frail and my Grandmother started developing a brain disorder which eventually took away her speech, brain processing and her life.

And this deterioration in health and onset of age-related diseases with age (could be cancer, Alzheimer’s, other brain disorders, frailty etc.) was not unique to my grandparents. I’m sure a lot of you have seen some elders in your life suffer from it too. Most elderly people ultimately suffer from age-related diseases – it’s just a matter of when the disease arrives and your chances of getting these diseases only keep increasing with age. That’s sad. It’s sad because it signals that eventually each of us has to suffer in old age. And it truly hurts to watch that suffering.

But what if we didn’t have to suffer in this manner? This is where the aging field could truly rescue us.

Now, what is the aging field trying to do? We are trying to reduce this suffering felt by the elderly and their loved ones. We are trying to reverse some of the damage in our bodies to make the elderly feel healthy again. Even if you don’t want to live too long, I’m sure you want to be healthy in your later years. And it’s not that easy to prevent these aging disorders unless we come together to solve this problem. And it means each one playing their part in whatever capacity works for them – starting companies, doing research, raising awareness, donating etc.

There are brilliant scientists and companies doing work in this field to bring back our youthful states when we are older. It is tremendous work all of us could benefit from and if it works, we can all be healthy for longer. Isn’t that something truly wonderful? 

I certainly want to be healthier for longer. I certainly want to spend quality time with my grandchildren. I certainly wish I could have spent more time with my grandparents. And this is why I’m so excited about supporting the field of aging and longevity. And I hope I can get you excited too.

Because at the core of it, longevity science will enable deeper and longer human connections.”


P.S. If you want to learn about some of the work being done by these brilliant scientists in the longevity field, subscribe to my YouTube. It’s new and I’d love your support! I’ll be releasing interviews with aging researchers with the intention of bringing their work from the lab to the public. 

If you’re interested, make sure to subscribe so you are notified when the interviews get released. I’ve already recorded some interviews so they should be out soon, but in the meantime, you can watch a persuasive speech I gave on a controversial topic “You’re Never Going to Die.” In the video, I explain aging using a banana analogy and it’s a fun watch – enjoy!

Epistemology, Philosophy, Societal musings

Do people really need human connection?

The typical argument given for people needing human connection is that we have evolved to need human connection. We are wired to want human connection. Perhaps babies are wired to want human connection before they can actually start thinking, reasoning and being creative to a larger degree.

But for the rest of us, does it make a difference if we have evolved to want human connection or not? Aren’t we constantly doing things outside of what we are “evolutionary wired to do.” We are evolutionary wired to live in forests, but most of us live under concrete brick walls. We are evolutionary wired to only eat nuts and berries and fish, but we eat pizzas and burgers. We are evolutionary wired to not use technology but almost all of us have phones and computers.

And the biggest one – we are evolutionary wired to pass on our genes but some of us choose not to have kids.

Humans are constantly creating, ideating, and doing things outside of what evolutionary biology dictates. We come up with reasons and ideas that make it plausible for us to do so. David Deutsch highlights this point in his book Beginning of Infinity and in his interview with Tyler Cowen.

Having laid this out, let’s revisit the question in my title – do we really need human connection? There is this fear around robot sex dolls (which in fact, I’ve written about before), and technology replacing human connection which is supposedly not going to be good for humanity. Is it really the case that it won’t be good for humanity?

What if we come up with reasons and explanations that make us okay with not wanting human connection? What if we come up with reasons that make us want to interact less with other humans? And indeed, there are cultures that are more individualistic (and have been for a long time). It is quite possible that we come up with explanations that make us want to only interact with our computers. Perhaps children playing video games already do this. Now, the reasons and explanations we come up with for not wanting human connection (and apparently going against evolution) may not be good explanations, but they could still drive our behavior towards less human connection.

And what if these explanations don’t indicate how less social connection will be bad for humanity? It may be the case that less human connection doesn’t in fact have “detrimental” consequences such as loneliness or depression. In all those studies that say lack of social connection is causing depression, could it be the case that it’s not lack of social connection, but it’s eating unhealthy food or something more bizarre like not being considered attractive by your peers? Perhaps it could be. I say this because I’m not sure if the studies that claim that lack of social connection causes depression give explanations that are not hard to vary. Depression could be the result of other reasons not accounted for. But maybe I need to look more into those studies.

Look, I don’t know the answer to my question(s). I’m just conjecturing and laying out my thoughts. But I do think there is no settled science or objective truth on whether humans (outside of babies) absolutely need other human connection. Or at least I don’t know of a good explanation that makes me believe so. Give me one and I could change my mind. Please feel free to criticize my thinking so I can improve upon it.


P.S. Btw, I like human connection and I want it. But my point is I’m not sure if we “need” it and if there are negative consequences without it.


Why I’m Excited About Longevity Science and You Should Be Too

A few days ago, Doug, his parents, and I, visited Doug’s maternal grandparents at their old age home living facility in Michigan.

“My dear, these pictures are so wonderful! I’m so glad you’ve been able to spend time hiking and visiting national parks. Isn’t it great that you can work and camp at the same time? How times have changed! I wish I could do the same when I was your age,” remarked Grandma as she looked through the pictures of our nomadic adventures from this past year.

After some more chit chat and snacking on celery, we headed down to dinner. As we walked into the restaurant at the old age home facility, we were greeted by a crowd of old people gathered around tables. Some preferred to eat their meals quietly by themselves, while others preferred to sit in small and large groups. But one thing was common across all of them – they had the glow of wisdom and happiness on their faces. I wished I could soak in all the wisdom they had to impart. 

At the end of dinner, a few of the residents came by to say hello to Doug’s grandparents. And perhaps also because they were curious to know who the visitors were.

“Fran, meet Doug and Molly. They are visiting me this weekend and headed to Italy tomorrow!” said Grandma.

“Headed to Italy? Oh, how wonderful! You must go to Florence,” said Fran. And then she turned to Grandpa and asked him, “Have you been to Italy? You must go to Italy, it’s such a beautiful place!”

Grandpa laughed. “Fran, it’s too late for me to go to Italy now. Perhaps my soul will pass through Italy once I die,” he joked.

Fran responded, “Alright, alright. Anyway, I must tell you – this past weekend I was at my granddaughter’s wedding and it was the most beautiful wedding I’ve attended. The flowers that adorned the tables were bright and intricate. And my granddaughter – oh she looked ever so gorgeous. She came up to me and said, “Nanny, don’t die, don’t leave me please. I’m so glad I was able to attend her wedding. I must show you some pictures later – do they stay on Facebook or will they disappear after posting? They stay? Oh great! Then I’m going to go look at them again. Nice to meet you, Doug and Molly and have a wonderful time in Italy.” And with that, Fran trotted off to look at her granddaughter’s wedding pictures.

We headed back to the apartment after dinner and Grandma looked at me and said, “You know Molly, Doug used to be my investment broker 10 years ago? It was a great way for him to earn side money. I knew he’d go into Investing. He’s been doing it since he was a kid.”

I laughed. “Why am I not surprised? I said. “He will often excitedly explain option strategies to me that pass over my head. But he seems to get them so intuitively,” I added.

“Oh yes, that’s Doug! Doug dear, do you mind looking through my stock portfolio and advising me on a few things?” Granny asked.

“Of course,” responded Doug. As Doug sifted through Grandma’s stock papers, he said, “Grandma, next time, can you please call me up when you have stock recommendations? You should be the one advising me! Your fund performance is better than that of most professional investment funds!”

After a bit, Grandma took us to see the library across from her hall. We started discussing books and she told me how she had been reading a lot of non-fiction and history books recently. “You know dear, I don’t have many days left and I want to learn as much as I can in the time remaining.”

On the drive back home, I couldn’t help but run through the conversations in my head. I thought of how advancements in aging science will change the nature of the conversations. I thought of why I’m truly excited about longevity science. And I thought of how the world would look like with progress in aging science.

Just for a few seconds, imagine with me. Imagine the following world:

Grandpa and Grandma are able to hike and camp with you. They will no longer be saying, “I wish I could do the same when I was your age.” They will be doing the same at their age. Grandpa will be able to visit Italy even in his 90s and later. He won’t have to wait for his soul to pass through Italy. The Fran’s of the world will not only be able to visit their granddaughter’s weddings, but also their great and great great granddaughters’ weddings. 

You and I will have years and years to soak in all the wisdom from our grandparents. Oh, the amount we’d learn! Grandparents will be so sharp even beyond 100 years of age that we will be the ones asking them for stock recommendations! Grandma will have time to read all the non-fiction, fiction, and history books she wants to. And beyond any of this, generations of family members will be able to bond, form deeper connections, and live healthily for years to come.

Wouldn’t you want to live in a world like this? If you think life is beautiful and you can remain healthy in your “older” years, I assume that you would want to live long enough to meet generations of your family to come. And I think this is possible. And this is exactly why I’m excited about advancements in aging science.

Yes, it’s incredible to see the progress that science is making everyday. Yes, it’s incredible to see the progress made by technology and biotechnology. Yes, it’s incredible to see the progress made by brilliant aging scientists. But you know why all of this is incredible?

Because at the core of it, longevity science will enable deeper and longer human connections.
