The Greatest Legacy For Future Generations
What can you actually leave behind?
Marcus Aurelius wrestled with it in the 2nd century, in the margins of his Meditations. Viktor Frankl, the Austrian psychiatrist who survived Auschwitz, gave his own answer in Man’s Search for Meaning. Steve Jobs distilled it into six words — make a dent in the universe.
When we leave this world, what can we actually leave behind?
The most systematic answer I’ve found came from an unexpected place: an 1894 lecture by Kanzo Uchimura — a Japan-born thinker educated at Amherst College, who spent his life writing in conversation with Locke, Bunyan, Carlyle, and Cromwell. The lecture was simply titled The Greatest Legacy for Future Generations.
Uchimura rejected the obvious answer — a name in history books, a monument to yourself — and offered four candidates instead:
Money — accumulated with purpose and spent for the common good. His example: Stephen Girard of Philadelphia, the French-born merchant whose accumulated fortune built what was, in Uchimura’s day, the largest orphanage in the world.
Business — enterprises and infrastructure that outlast the builder. He cited David Livingstone, the Scottish explorer whose expeditions opened Africa’s interior, and Oliver Cromwell, whose political work still shaped 19th-century Britain two centuries after his death.
Thoughts — written ideas that require no wealth or position. Uchimura singled out John Locke’s Essay Concerning Human Understanding, which he argued moved through Rousseau, Montesquieu, and Mirabeau to ignite the French Revolution. He also named John Bunyan’s Pilgrim’s Progress — written by a largely uneducated tinker who had been imprisoned for his preaching.
A noble and courageous life — living with integrity and overcoming hardship. Available to anyone, regardless of wealth, education, or position.
He then ranked them. Money and business depend on talent you may not have and opportunities you may never get. Thoughts are more accessible — anyone with something honest to say can leave ideas behind. But the greatest legacy, the one he insisted anyone could leave, was the fourth: a sincere, courageous life.
This is the lecture that named our company.
GLASP = Greatest Legacy Accumulated as Shared Proof.
When we ask what Glasp is actually for, the answer sits inside Uchimura’s framework. Of his four legacies:
The first two — money and business — are not our domain. They require capital, position, timing.
The last two — thoughts and a noble life — are exactly what we’re building for.
Thoughts, because every highlight you make, every note you write, every passage you share is a small piece of your thinking preserved and made accessible to someone you’ll never meet. This is what swyx — host of the Latent Space podcast and the developer-writer who popularized “Learn in Public” — calls “learning exhaust”: the byproduct of your learning that, when made public, becomes fuel for someone else’s.
But here’s what’s easy to miss: the trail of your reading is also a noble life.
What you chose to mark is what you thought. But how you marked — over what years, at what hours, with what consistency — is how you lived.
This is something a profile page can show that a finished essay cannot. A decade of weekly highlights. A reader who kept returning to the same author for fifteen years. Someone who logged thirty notes the month after losing a parent. Someone who, between full-time work and raising two kids, still read sixty books a year. None of that shows up in the polished output. All of it shows up on a profile page.
When we look at someone’s library of highlights and notes, we’re not just seeing their thoughts. We’re seeing the shape of a life spent learning — the patience, the persistence, the seasons of obsession, the quiet years. That’s what other readers respond to. Not the cleverness of any one annotation, but the dignity of a life spent paying attention.
This is, in Uchimura’s sense, a noble and courageous life made visible — not in monuments, but in the steady accumulation of attention over time.
This is what Austin Kleon, the artist and author of Show Your Work!, argues — that working in public, with honesty, is itself a form of legacy. You don’t need to write an Essay Concerning Human Understanding or chart the interior of a continent. You just need to be sincere about what you’re learning, and generous enough to share it.
A century later and thousands of miles away, Steve Jobs reached the same conclusion from the opposite direction — through product, not philosophy. In the final pages of Walter Isaacson’s biography, Jobs dismissed the prevailing Silicon Valley playbook — founding a startup to flip it, cashing in, moving on. Real work, he insisted, means building something that will still stand for a generation or two. And you do it, in Jobs’s words, to “add to the legacy of those who went before.”
Gratitude for the past. Contribution to the future. More than a century apart, the same idea.
This is why, in Hatching Growth #16, we coined a term for how we build: Legacical Thinking — thinking not in years or decades, but in centuries. Uchimura’s lecture is the source code. Every product decision at Glasp is filtered through a single question: does this help someone preserve, express, or pass down their thinking in a way that still matters centuries from now?
Uchimura would recognize it. He spent the last third of his lecture arguing that the greatest legacy isn’t reserved for the rich, the powerful, or the literary. It belongs to anyone willing to think in public.
Which brings us to the only thing worth saying directly, before we close:
Your thoughts are a legacy. Your honest life is a legacy.
You don’t need wealth, position, or a name in history books. You only need the willingness to think out loud — and to share what you found worth marking.
That’s what we’re trying to make easier.

This is what we stand for!
Writing is a unique act that activates both cognitive and psychological aspects of a person. Our phonetic organs—the tongue, palate, pharynx, and diaphragm—cannot keep up with the speed of our thoughts during speech. Writing follows thoughts, provides feedback to the brain, keeps the thinking process active, and develops ideas. Therefore, the act of writing is a more active process than speaking. The intellectual abilities of our minds take on a more vivid form through writing. Through the act of thinking, we also gain the opportunity to experience a deeper awareness of what it means to be human. When a person begins to write, they begin to rediscover themselves and their environment (nature, science, etc.). Essentially, writing is about beginning to exist and continuing to exist. Once you start writing, the story unfolds. Moreover, the emotions and thoughts that nourish the story become fluid and permanent through writing. Ideas don't just fly away. In this dystopian age, where artificial intelligence is beginning to enter our lives and where the fake and the real are intertwined, capturing sincerity and expressing ourselves will not be easy. Today's toxic lifestyle, characterized by rapid consumption and insatiable greed, will alter and complicate our emotions, thoughts, perceptions of the world, and the way we relate to others. In this new world order dominated by deceit, achieving sincerity and honesty will not be easy. Therefore, we will need sincerity, tolerance, and love more than ever. Please, hold on tightly to life, to the values that sustain you, and to your loved ones. Every person tries to express themselves throughout their life. They express this by processing the knowledge and experiences they acquire in different ways. Everyone's way of expression is different. Some make music, some sculpt, some write poetry, some engage in science and make discoveries. Throughout their lives, people have an intellectual journey and accumulation of ideas, insights, struggles, discoveries, and lessons. But 99% of this knowledge remains locked away in their heads and disappears the moment they die. This is a huge loss for humanity. Those who can express themselves concretely are able to pass on this accumulated knowledge and experience to future generations through the works they leave behind.
Most people don't write books; most people don't record their worldviews, knowingly or unknowingly. Yet their experiences are of extraordinary value.
That's why I'm now writing articles, poems, and essays. I think this has become my way of expressing myself. If I were to leave this life's journey without writing down the ideas, feelings, and hypotheses that I find valuable, I would die with my eyes open. This is what gives me peace.
