What We Know

On some days, if you asked me about what we know, with absolute certainty, I’d respond with “only that something exists.” And if you asked me what that meant, then I’d add “to appreciate and work with what exists.”

This seems basal and little. But I don’t see it that way. That something exists is certain; but contrary to how academic philosophy regards this as a tiny foundation to base anything on, I take it as extremely powerful. Something exists. To appreciate and work with what exists, though I’m not sure I wouldn’t later rephrase this, seems likewise powerful to me. What can we do with what exists? What should we do with what exists? I’m not the philosopher yet to develop a conception of freedom out of this, but I recognize the possibility.

Something exists. An immensely unsatisfying non-statement at first, but apart from appearing to be the only thing we can be certain of, it may well be pure magic.

Happy holidays 🎄

Update (April 7, 2019)

Just as I had learned about Kris McDaniel’s The Fragmentation of Being (lauded by Notre Dame Philosophical Reviews), here, “something exists” is not tied to anything concrete or abstract: ∃xFx ↔ ∃Cx(Fx) ∨ ∃Ax(Fx) is not the question; all that matters, for the purposes of this post, is ∃x.

About Me

Jens Oliver Meiert, on March 2, 2026.

I’m Jens (long: Jens Oliver Meiert), and I’m an engineering lead, guerrilla philosopher, and indie publisher. I’ve worked as a technical lead and engineering manager at various companies (e.g., Google); I’m an active web and tool developer (code optimization, digital defense), a contributor to web standards (like HTML, CSS, WCAG), and a book author (O’Reilly, Frontend Dogma).

I love trying things—in web development and engineering management, but also in politics and philosophy, where I hold to one idea in particular: that we can only be well if we take good care of everyone. Here on meiert.com I talk about some of my perspectives and experiences. (Please share feedback: Interpret charitably, keep it friendly, but do be critical.)
