A reliable philosophy should point the way when we need guidance. It should be our framework that helps us make decisions, like the kind as heavy as how we should treat each other, especially when we have chosen the burden of governing ourselves. But maybe more importantly, it should comfort us when we feel lost, when hope has faded, when we can’t help but wonder why we’re here in the first place. A reliable philosophy should help us understand who we are and why, so that everything we choose to do makes sense.
The untenable discord in our world today suggests that we’re still looking for it.
Here are lyrics from the song “Message in A Bottle” by the Police, circa 1979, but feeling timelessly human:
Just a castaway, an island lost at sea, oh
Another lonely day, with no one here but me, oh
More loneliness than any man could bear
Rescue me before I fall into despair, oh
After sending an “S.O.S. to the world,” a message in a bottle thrown into the vast open sea and entrusted only to chance, there is this realization:
Walked out this morning, I don’t believe what I saw
Hundred billion bottles washed up on the shore
Seems I’m not alone at being alone
Hundred billion castaways, looking for a home
We’ve had millennia of philosophers producing some of the most brilliant work in human history, but we have yet to find the anchor point for all those castaways.
I believe that is because the key to it all has only recently been made available to us.
The ancient Greek philosophers never had access to the results of the Human Genome Project, published in 2003; nor did most of their more contemporary counterparts. In fact, humanity has only had access to Charles Darwin’s Theory of Evolution for the last 150 years, and it was only about a hundred years ago that Darwinian evolution was seen to be compatible with Mendelian heredity.
Long story short, what has been missing is an understanding of how life really works, especially how it changes over time.
Around 2500 years ago, Heraclitus of Ephesus said that a man cannot step into the same river twice, meaning that the flowing water was, like all other things, constantly changing. He was really on to something. Here’s what that means, given what we now know:
Life changes over time. That is a defining principle. An individual organism changes as it grows older, and it will have acquired more information at the end of its life than when it began. Consider an acorn becoming a tree, a caterpillar becoming a butterfly, a primate learning to use a stone to crack nuts. The wonders of an individual lifetime.
More importantly, science has shown us that life evolves over generations. Every living thing on Earth today traces its genetic origins back to the original organisms at the dawn of life on this planet. No longer do we need to rely on mere speculation, or even our best interpretations of the fossil record; our understanding of DNA proves this. And the fact that there are countless varieties of complex life now when only simple life once existed proves that life becomes more complex over time.
Science has come to define DNA as a carrier of information, as information itself. DNA is the information that is used in the construction and operation of individuals, and then that information is passed on to the next generation. Instead of a “message in a bottle” cast into the unknown, it is a message packaged up and passed along with intent, where it can be guarded and nurtured as if it were the greatest treasure that could be possessed, as if it holds all the genetic information given to us from all previous generations, because it does.
When connected to the next level of this process, the pattern becomes much more apparent, more resilient, and even more beautiful. This next level is embodied by the accumulation of knowledge that made our understanding of DNA possible.
Over time, humans have invented and refined the means to pass along information not just through genetics, but by language. We have created the means to encode and store information in a way that transcends the ordinary lifespan, and allows it to be transmittable across both space and time, virtually without limit. Information is no longer relegated to a gift of one generation to the next; beneficial information acquired today can be spread across the entire planet and used by the entire species within seconds. If DNA has been the carrier of information that allowed life to evolve, language and encoding of meaning represent the evolution of information, which has allowed us to become even more successful in the world around us. The act of evolving has itself evolved, becoming more complex over time.
What this all means is simple, but profound and irrefutable: the value of each individual organism alive today, whether plant, animal or other, is that each carries with it all the genetic information passed on to it from previous generations, an unbroken chain back to the very beginning of life on this planet. For a human being, prone to feeling lost and isolated, this is the immovable anchor point to hold on to.
From this anchor point, the direction forward is determined by simply acknowledging the pattern of the past. If those who came before us, regardless of form, lived and experienced, and their experiences were passed down to us in ways that benefitted those generations that followed, then our purpose is the same: to evolve individually over time, and then to pass along what we have acquired to generations that follow. To learn, and experience, and then to teach. That is the essence of a meaningful life.
When hope has started to fade, when belief in our common humanity has started to faulter, when our mythologies give us reason to build more walls than bridges, science finally offers us an understanding of ourselves that can unite us in meaning and purpose: we exist to better understand the world, so that we can offer up that understanding to generations that follow, so that they can be one increment more successful than we were.
With our awareness of nature’s pattern for life, how can we not follow it with more intention? With this meaning and purpose now being obvious, how can we not reestablish our governing and cultural priorities to embrace this path that we are already on, and focus our efforts to maximize our evolution?
If we did, if humanity, as a community, as a species, pursued a common and continuous path of learning and teaching, with passion and intent, expressly to benefit those who come after us, we would no longer be blindly drifting along, nudged by nature’s current. We would be hoisting a sail, together, heading off in the direction we now know we’re predestined to take.

Some references regarding the current state of research on DNA for any reader looking to follow the discussion down a more detailed, scientifically specific rabbit hole:
Here is a 2019 article by Raymond M. Keogh called DNA & The Identity Crisis | Issue 133 | Philosophy Now in which he uses the recent developments in genetics to better define the concept of “the individual”. This is a useful exercise, and it shows how we are starting to redefine terms using our newfound tools.
For an in-depth background on how DNA works as transferable information, an excellent (albeit very scientifically dense) roadmap of where the science currently lies can be found in this article by Peter R. Wills from 2016:
The tagged references in the Wills article mentioned above can take you down countless paths, each delving deeper into the latest findings and understanding of how DNA works, how life may have crossed the line from non-living to living, etc.
The piece was published by the Royal Society, a scientific association founded in 1660 to promote the findings of science as what was back then a new endeavor for humanity. Contributors to their journal have included Isaac Newton, Michael Faraday, and relevant to this discussion, Charles Darwin.
