We swallow greedily any lie that flatters us, but we sip only

Denis Diderot, philosopher of the Enlightenment, once revealed a deep wound in the human condition when he wrote: “We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter.” In these words, he showed how fragile the human heart can be, preferring comfort over clarity, illusion over reality. We are quick to embrace praise, even if false, but slow to accept correction, even if it will save us. This quote is not only a critique of human weakness but also a summons to courage, to love truth more than the sweetness of deceit.

The lie flatters because it feeds our pride. It tells us we are better, wiser, stronger than we are. Like honey to the tongue, it is swallowed without resistance. The truth, however, often reveals our faults, our errors, our mortality. It stings the ego, it humbles the spirit, and so we resist it. We take it in reluctantly, sip by sip, like a bitter medicine. Yet Diderot reminds us that though the truth may burn as it enters, it heals as it works, while lies, however sweet, rot us from within.

History proves this lesson. When Galileo declared that the Earth moved around the Sun, the leaders of his time called it a bitter truth. It wounded their pride and threatened their authority. The people preferred the lie that flattered their sense of order: that humanity stood at the center of the universe. They swallowed the illusion greedily, while resisting the truth for centuries. And yet, in time, the truth could not be denied. Though bitter at first, it opened the way for science, progress, and a clearer vision of reality.

So too in politics and society. Leaders who promise greatness without sacrifice, glory without struggle, are cheered by the crowds, for they offer flattering lies. But the leader who speaks of hard work, of pain, of patience, offers the bitter truth, and is often resisted. Abraham Lincoln, when he told Americans that the Civil War would be long and bloody, gave them a bitter draught. But it was the truth that sustained them to endure, while the easy lies of compromise could never have healed the nation.

Diderot’s words are a mirror to our own daily lives. How often do we accept compliments without question, but bristle at criticism? How often do we cling to excuses rather than face our failings? Each time, we prove his wisdom. The soul grows not by the flattery of lies but by the discipline of truth. To reject bitterness is to remain weak; to accept it is to grow strong.

The lesson is luminous: love the truth, even when it hurts. Swallow it not sip by sip, but with courage. For the truth is not your enemy, but your teacher, your guide, your healer. Lies will leave you blind, but truth, though painful, will give you sight. The wise know this, and they choose truth over comfort, reality over illusion.

Practically, this means welcoming honest voices into your life, even those that sting. It means asking not, “Does this please me?” but, “Is this true?” When flattered, pause; when corrected, listen. Train yourself to drink the bitter medicine of truth with gratitude, knowing it will strengthen you. Encourage truth in others as well, not lies that soothe, but words that guide.

Thus, remember Diderot’s warning: “We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter.” Be not among the greedy who feed on lies, but among the brave who drink the cup of truth. For in truth lies the path to freedom, and in freedom lies the fullness of life.
