This Week’s Idea

— Flux —

Flux is impermanence. To think about this idea, think about change. The universe, your things, and you.

Greetings!

Good news — with a new year, the Weekly Wisdom Builder begins anew.

This week we focus on flux. We use the impermanence of reality to forge a layer of wisdom.

I’m excited about this new format. The old WWB was fun, but centering each week on a single idea makes everything clearer and more meaningful. And starting with flux is poetically on point. Everything changes — including WWB — and now the format itself embodies the idea. Each week, we’ll reflect on one idea and explore a half-dozen quick hits around it. Click the title when inspired to read more. Skim it or dive in — this is great way to spend five minutes of your week.

This week’s collection explores Heraclitus, the ancient thinker behind the idea of flux, and the simple but unsettling insight that everything changes. Our examples touch on the constellations, your own time on Earth, the basic idea of causality itself, and for context, the ancient Presocratic philosophers of Greece, the thinkers of Heraclitus’ time.

Story of the Week

Heraclitus

born circa 535 BCE

circa 535 to 475 BCE, likely aged about 60 years old

Heraclitus lived around 500 BCE in the Greek city of Ephesus, and he saw something most people miss: nothing ever truly stands still. Rivers flow. Fires burn. Lives change. Even the things that look solid are only holding their shape for a while. Heraclitus wrote in sharp, almost cryptic fragments, not essays, which earned him the nickname the Dark Philosopher. But beneath the mystery was a clear idea—reality is not made of fixed things, but of processes in motion. Order still exists, he argued, but it comes from tension and balance, not permanence. Two and a half millennia later, physics quietly agrees.

Quote of the Week

“Everything is in flux.”

Heraclitus
500 BCE

Heraclitus’ claim that “everything is in flux” captures a deep truth shared by both metaphysics and classical physics. The world appears stable only because change often happens gradually. Beneath every solid object, fixed identity, and steady law lies continuous motion, transformation, and becoming. What endures is not stillness, but patterned change.

Weekly Crossroads: Takeaways

Wisdom at the crossroads of knowledge.

Wisdom emerges from the consistent exploration of the intersections of philosophy, science, critical thinking, and history.

1START: Science »

Will the night sky have stars nearly forever?

Every star you see at night belongs to the Milky Way — some can see a few of the closest galaxies. All gravitationally bound and unaffected by cosmic expansion. For centuries, humans assumed the night sky was eternal and unchanging. Modern cosmology reveals a subtler truth: while the universe expands, gravity preserves the stars.

2Philosophy »

What does existence before essence mean?

The idea of existence before essence is most closely associated with modern existentialism, especially Jean-Paul Sartre. It rejects the notion of a soul or destiny and instead places responsibility on the individual to shape who they become. In contrast, essence before existence claims identity or purpose precedes birth. At its core, this debate lives in metaphysics, asking whether identity is discovered or created, and whether meaning is inherited or earned.

3Critical Thinking »

Is cause and effect certain?

Reasoning is one of the Five Thought Tools, it demands we question whether we’re seeing real causation, or just a misleading correlation. Always ask: What’s the evidence? Hume said, repeated observation shows habit, not logical necessity.

4History!

Who were the Presocratic Philosophers?

The presocratic philosophers were the first to perform simple science, observation of nature. Figures like Thales, Anaximander, Pythagoras, Parmenides, Heraclitus, and Democritus pursued truth through reason and observation. The later sophists, by contrast, focused on persuasive skill.

Echoes of the Self: Exploring Consciousness Across the Ages

Consciousness

Consciousness, at its most basic, is the act of cognition engaging with sensory input. When an organism can take in information and process it, consciousness is present. Self-awareness, reflection, emotion, and identity are later developments—important, but not required for consciousness itself. Consciousness is the state of being aware—of the world, of oneself, and of experience itself. Across history, it has been described as soul, mind, spirit, or brain process. While explanations evolve with knowledge, the core phenomenon remains: subjective experience arising within a thinking organism.
