Definition
Three billion heartbeats is the existential framing of finite life under naturalism: mortality is real, final, and therefore value-laden.
Why It Matters
This is the ultimate ‘urgency’ metric. By framing life as a finite number of heartbeats, it strips away the ‘laziness of eternity’ and forces a radical focus on what actually matters, transforming mortality from a fear into a fuel for a meaningful life.
Core Concepts
- Naturalism removes expectations of personal afterlife.
- Finite life can intensify care, gratitude, and urgency.
- Honesty about death is compatible with emotional depth.
- Meaning is constructed within the span of life, not deferred beyond it.
