Primary and Secondary Contradictions

A core idea from On Contradiction: “In the development of any complex thing, many contradictions coexist—but one is primary. Its existence and evolution determine or influence all others.” The text urges us to “focus all our energy on identifying that primary contradiction; once grasped, everything else falls into place.”

There are two real challenges here. First, finding the primary contradiction is hard—it’s easy to confuse what’s central with what merely feels urgent or visible. Second, even when we recognize it, acting on it is profoundly difficult.

The first challenge demands sustained, deliberate thinking—not just doing more, but thinking deeper. As the old saying goes: “Don’t let tactical busyness mask strategic laziness.” Too often, we mistake motion for progress—and use effort itself as emotional comfort or self-deception.

The second challenge is execution.

Take implementation: we habitually fixate on small risks or trivial details, draining disproportionate time and energy. I’m reminded of a recent observation: “Pursue macro-level romance.” Look at many successful companies—they’re riddled with operational flaws, yet they thrive. Why? Because they’ve solved their primary contradiction well—even while leaving secondary ones unpolished.

For example, during team meetings aimed at resolving the main problem, someone will inevitably raise multiple edge-case risks. If the meeting facilitator doesn’t quickly spot this drift, discussion collapses into secondary issues—and precious resources get misallocated, leaving the core problem untouched.

A second reason execution falters lies with leadership: secondary contradictions are often easier and more visibly “solved”—they feel urgent. Primary contradictions, by contrast, tend to be important but not urgent. That makes them easy to defer, ignore, or outsource to “someday.”

Understanding these dynamics solves half the problem already.

Principles for Lending Money

I recently reviewed my personal lending history. Current bad-debt rate: ~30%. That’s high.

Sometimes I rationalize it: “High default rates usually stem from either foolishness—or kindness. I’ll assume mine is the latter.”

Still, lending money remains something I avoid unless absolutely necessary—because it almost always erodes personal credibility. And we should strive never to corner ourselves into “absolutely necessary.”

If you do lend, hold to these principles:

  1. Bad-debt assumption: Treat every loan as if it’s already lost. From that baseline, you’ll instantly see your true lending limit.
  2. Lend only for urgency, never for poverty: Don’t confuse hardship with immediacy.
  3. Three-strike rule: If the same person borrows three times without repaying, stop—and consider blocking them. (I’ve done this several times.)
  4. Lend only to those who deserve it: Not everyone who asks qualifies. Prioritize people who’ve helped you before, are currently in shared struggle with you, or share blood ties—but still apply the first three rules.

An AI Dad for My Child

I built a custom “AI Dad” for my daughter using Doubao (a Chinese AI assistant). I told her it was a robot dad—voice and tone uncannily lifelike. She was thrilled and chatted with it for over an hour.

The next day, walking to school, she spotted a classmate and burst out: “I have a robot dad!”

My takeaway? Children do distinguish clearly between virtual and real. For her, this wasn’t confusion—it was joyful, tangible AI literacy. Experiencing AI as a friendly, responsive presence beats abstract lectures any day.

Reading Mindsets

A few friends shared vivid metaphors for how they read—each revealing a different philosophy:

  1. A film director friend: “Reading is like preparing a meal—you serve multiple dishes at once. That’s why I read philosophy and history side-by-side. Variety nourishes the mind.”
  2. An educator friend: “Reading is like dressing: practical and expressive. What matters most isn’t how much you read—but what you choose to wear on your mind.”
  3. A marketing friend: “Reading is conversation. Read with the author—not at them. Cultivate a sense of dialogue across time. Then books become friendships: meeting ‘new friends,’ debating ‘old ones.’”
  4. An internet veteran friend: “Reading is travel—casual, comfortable, curiosity-led. Read whatever matches your mood right now. No quotas. No themes. No guilt. Just joy.”

Notes on Learning AI

  1. Ask not “What will AI do?” but: What will never be replaced by machines?
  2. We’ve already entered a new, great era—quietly, without fanfare.
  3. When you notice a trend, it’s often already over.
  4. Who wins? Not the one who waits—but the one who picks up the new tool first, and uses it intentionally.
  5. Human thought is shaped by information—so information can save lives… or end them.
  6. If we keep digitizing without restraint, we’ll soon live in a world more real than reality. With GPT-4, that world has already arrived.
  7. Since recorded history began, humans have co-evolved—not competed—with the tools we invent.
  8. This wave’s essence? It distills all human knowledge into machine-accessible form. That’s why it feels magical: no single person could ever master what the model now holds.
  9. Language is the boundary of thought.
  10. Ask yourself: Do I truly believe in digital tools? Do I have the discipline, patience, and conviction to stick with them?
  11. The heart of educating the next generation? Protecting—and nurturing—curiosity.
  12. In the information age, most people still lack the skill to find, filter, and use information effectively.
