The Law of Reason: Why Humanity Requires Filial Piety

Observe a nest of baby birds in the wild. For weeks, the bird parents sacrifice themselves completely—foraging tirelessly, fighting off predators, and enduring the elements to raise their young. But after 15 to 20 short days, the fledglings take a leap. They leave the nest.

What happens next? There is no next.

The fledglings will never come back to care for their parents. Once they fly away, they become forever strangers to the very birds who gave them life. This is the heartbreaking, yet undeniable, law of the animal kingdom.

The Tragedy of Parental Alienation

Birds are animals, governed strictly by the law of sheer survival. But human beings are not designed to operate that way. This is why cases of "Parental Alienation"—where adult children fly from the "nest" and cut off or abandon their parents entirely—feel so incredibly jarring.

When humans mimic the bird, walking away from their creators to become forever strangers, it breaks the parents' hearts. It violates a deep, intrinsic code woven into the human spirit. English historian Edward Gibbon famously articulated the distinction between the animal kingdom and humanity:

"The law of nature instructs most animals to cherish and educate their infant progeny. The law of reason inculcates to the human species the returns of filial piety."

The "Law of Reason" is what separates us from the birds. We are imbued with memory, gratitude, and empathy. For humans, to take the sacrifices of a parent and offer nothing in return when that parent grows old is to operate outside of human reason itself.

"Let It Be" (随缘) - The Sorrow of Abandonment

The sorrow of a fractured parent-child bond is captured beautifully in the classic Cantonese song "随缘" (Cheui yun / Let It Be) by artist Deric Wan (溫兆倫). The haunting lyrics speak directly to the painful realization that sometimes, despite the deepest love given, people drift apart like strangers:

"No matter how deep the love is, how innocent the smile is—
There's nothing left to keep in the end.
Looking up at the sky vacantly, who's hiding behind?
Ah~ All the thoughts in the dream are missing...

Looking back at this life, people fall into the net like flying insects,
We must endure all the hates and sufferings.

You and I met by chance,
It's always ridiculous to think of all the laughing and shouting.
We keep advancing and regressing, how can it last forever?
Ah~ Whether it's cold or warm, we must bear it..."

The Lifelong Practice of Childing

While artists capture the melancholy of alienation, the philosophy of Childing offers the cure.

We must consciously resist the cold "Law of Nature" where children just walk away. The practice of filial piety is the conscious, daily decision to embrace the "Law of Reason." It is the act of looking back at the nest you fell from, returning to it, and ensuring that the ones who taught you how to fly never have to face the winter alone.
