Lessons from Lisbon, Madrid and Madison Square Garden

What Makes a Civilization Great?

What the Knicks and the Iberian Peninsula Teach About Greatness

As I watched the New York Knicks march toward a championship, I found myself thinking less about basketball and more about history.
Championships are often explained through the mythology of the superstar. We celebrate the dominant scorer, the transcendent athlete, the singular genius who carries everyone else to glory.
Yet the Knicks offered a different lesson.
Jalen Brunson was unquestionably their leader, but this was not a one-man team. Their success depended on relationships forged years earlier at Villanova. These were players who trusted one another instinctively, who understood where teammates would be before they arrived, and who were willing to sacrifice statistics, shots, and even money for a larger goal.
Brunson famously left substantial money on the table to help the organization assemble a deeper roster. In a professional sports world often defined by maximizing individual gain, he chose collective success.
The result was not merely a winning team. It was a cooperative enterprise. And history suggests that great civilizations are built the exact same way.

The Chemistry of Convivencia

During our recent trip through Spain and Portugal, I was struck by how often the story of Iberian greatness was actually a story of collaboration among very different peoples.
Long before the Inquisition, the Iberian Peninsula became the world’s vibrant center of learning. This didn’t happen because one culture triumphed over another, but because multiple cultures interacted in a unique ecosystem of coexistence, or Convivencia.

  • Romans contributed law, infrastructure, and language.
  • Muslim scholars brought radical advances in mathematics, navigation, and agriculture while preserving Greek philosophy.
  • Christian kingdoms eventually provided the political framework that inherited this vast reservoir of knowledge.
    But it was the region’s Jewish scholars and statesmen who often served as the vital connective tissue—the ultimate “glue guys” of the Mediterranean world—functioning as the translators, diplomats, scientists, and financial administrators who made the system run.

Hasdai ibn Shaprut (c. 915–970): The Ultimate Catalyst In the Golden Age of Córdoba, Ibn Shaprut served as a physician, translator, and foreign minister to the Caliph. He utilized his multi-linguistic mastery to translate the famous medical texts of Dioscorides into Arabic, establishing Iberia as Europe’s medical capital. As a diplomat, he negotiated complex alliances between Muslim rulers and Christian monarchs, proving that intellectual and political synthesis was the true engine of Iberian prosperity.

The Knowledge Enablers

When we look closer at the Golden Age of Spain and Portugal, the intellectual peaks were achieved not through isolation, but through an intentional exchange of ideas.
Consider Moses Maimonides (1138–1204), born in Córdoba. While globally revered as a towering rabbi and philosopher, Maimonides was also a brilliant physician who wrote extensively on hygiene, pharmacology, and psychology. His philosophical masterpiece, The Guide for the Perplexed, sought to harmonize Aristotelian science with divine revelation. His works were eagerly read not just by Jews, but by Christian thinkers like Thomas Aquinas and Muslim scholars alike, fueling the intellectual fire of the entire continent.
This collaboration yielded practical, world-changing technology. The famous translation schools of Toledo transformed Europe by turning ancient Greek and Arabic texts into Latin. Suddenly, Aristotle, Galen, and Ptolemy were available to a continent hungry for knowledge.
When it came to the Age of Exploration, Portugal’s maritime empire was literally guided by Jewish science:

The legendary astronomer and mathematician Abraham Zacuto (1452–1515) revolutionized navigation. His life’s work, The Perpetual Almanac, alongside his improvements to the copper astrolabe, allowed sailors to determine their latitude at sea using the sun rather than the stars.
Without Zacuto’s calculations and personal consultations, there might have been no Vasco da Gama reaching India, no Pedro Álvares Cabral reaching Brazil, and no Portuguese trading empire stretching from Africa to Asia.
The remarkable achievements of Spain and Portugal were not products of isolation. They were products of connection.

The Cost of Exclusion

Yet history also reveals how fragile such success can be. Beginning in the late fifteenth century, Spain and Portugal gradually abandoned the very conditions that had fueled their rise.
The expulsion of the Jews in 1492 systematically removed the most educated, skilled, and commercially connected citizens from the peninsula. Abraham Zacuto himself was forced to flee to Lisbon, and later Tunis, taking his brilliant mind away from the Iberian sphere.
This purge of human capital soon stretched from the cities to the fields. In the 1520s, the Spanish Crown banned Islam entirely, forcing the remaining Moorish population to convert or flee. These Morisco communities comprised the foundational backbone of Spain’s agricultural sector. For generations, they had engineered and maintained highly sophisticated, intricate systems of irrigation, terracing, and water management that kept the arid landscapes of Valencia and Andalusia incredibly fertile.
When this specialized expertise was systematically uprooted and driven out, the consequences were immediate and devastating. The complex canal networks fell into disrepair, agricultural productivity plummeted, and once-abundant yields dropped dramatically. Spain quickly found that you cannot exile your primary food producers without paying a severe price; as the agricultural infrastructure collapsed, localized famines began to creep across the countryside.

At the exact same time, enormous quantities of silver were flowing into Spain and Portugal from the Americas. Instead of stimulating innovation, this easy wealth reduced incentives to develop domestic industry or rebuild the shattered farming sector. The broad lesson remains: easy wealth can quickly become a substitute for creativity.
Meanwhile, nations such as the Netherlands and Great Britain adopted the exact playbook that had once made Iberia successful. They welcomed displaced Jewish merchants and skilled laborers, encouraged innovation, expanded scientific inquiry, and developed institutions that rewarded enterprise.
Leadership shifted. The world’s center of gravity moved northward.

The Contemporary Question

History does not repeat itself exactly, but it often rhymes.
Today, the United States remains the most innovative nation on earth. Our universities attract talented students from every continent. Our laboratories lead scientific discovery. Our entrepreneurs continue to create technologies that reshape the world.
But these strengths depend on openness.
Scientific progress thrives on collaboration. Medical breakthroughs emerge from international networks of researchers. Innovation accelerates when people with different experiences, perspectives, and skills work together toward common goals.
When nations become fearful of outsiders, suspicious of rigorous inquiry, or hostile to global intellectual exchange, they risk weakening the very forces that created their success.
The lesson of the Knicks is surprisingly similar to the lesson of pre-Inquisition Iberia. Greatness is rarely the product of a single star, or a single insular culture.
Whether in basketball, science, business, or civilization itself, success emerges from cooperation. The most successful teams are not always the ones with the highest raw talent; they are the ones that best combine talent, trust, shared purpose, and a willingness to sacrifice individual advantage for collective achievement.
Civilizations are no different.
The question facing every great nation is whether it will continue attracting talent, embracing knowledge, and building institutions that encourage cooperation—or whether it will retreat into exclusion and self-congratulation.
The Knicks answered that question on the basketball court. History answered it centuries ago.
The question now is whether we are paying attention.

I Went Back to my Kindergarten Class of 1958– Here is What I Told Them

Show and Tell, 67 Years Later

I arrive in Whitestone, Queens, in the soft, milk-glass light of 1958. The air smells faintly of chalk and floor wax. The sidewalks are narrower, the cars longer, the future quieter. I push open the classroom door and there you all are—knees scabbed, collars starched, haircuts obedient to gravity and mothers. Mrs. LaPenna stands watch, ruler nearby, smile doing most of the work.

You look up at me as if I’m a substitute teacher who took a wrong turn off the Whitestone Expressway. I tell you I’m one of you—just borrowed from a later inning of the same game. I’m here on a time pass from 2025, and I don’t have long.

I start with the easy truths.

“First,” I say, “you’re growing up in a good moment. The Dodgers have left Brooklyn, which hurts, but the Yankees are still a juggernaut. Elvis is on the radio. Ike is in the White House. Polio is on the ropes. Milk comes in bottles and your parents still believe tomorrow will be better because it usually is.”

A few of you grin. One kid in the front row adjusts his bow tie like it’s armor.

“Second,” I say, “hold onto this room. You won’t know it now, but classrooms like this—blackboard dust, wooden desks, a teacher who knows your full name—are where the country learns how to argue without fighting. You’ll need that skill.”

I tell you what’s coming, gently.

“There will be a man on television named Kennedy who makes politics look young. There will be marches where people insist—out loud—that America live up to its own handwriting. There will be a war you’ll see every night at dinner. Some of you will go. Some of you will protest. Most of you will just try to make sense of it all.”

You fidget. Big words for small shoes.

“So here’s the advice,” I say, and I lean in because advice should never be shouted.

“Be curious longer than is comfortable. Read beyond the assignment. Learn how things work—your body, a carburetor, a balance sheet, a sentence. When the world tells you to pick a side fast, slow down. Speed makes noise; understanding makes progress.”

I point to the windows. “Neighborhoods change. Whitestone will still be here, but it will look different. That’s not a loss—it’s a relay. You’ll carry what matters and pass it on.”

I pause, then add the part I didn’t know in kindergarten.

“You will fail at things you’re good at and succeed at things you never planned. That’s not hypocrisy—it’s growth. Be kind to yourself when the map gets smudged.”

Someone asks about the future—always the future.

I smile. “In 2025, you’ll carry a small rectangle in your pocket that knows almost everything. It will be miraculous and distracting. Use it to learn, not to disappear. And when it tells you the world is on fire, remember this room. Remember how a group of five-year-olds once sat still long enough to listen.”

Mrs. LaPenna clears her throat—the bell is coming.

“One more thing,” I say. “Call your parents more than you think you should. Thank teachers while you can. Save a photograph like this and look at it when you’re unsure who you are. You’re in here. So is everyone you’ll ever be.”

The bell rings. Chairs scrape. Time tightens.

As I step back into 2025, the chalk dust follows me for a second, then settles. I carry it with me—the proof that before the headlines and the hindsight, before the decades did what decades do, there was a room in Whitestone where the future sat cross-legged and waited its turn to speak.

A Father’s Legacy: Lessons in Life and Love

As time passes, memories fade, and the essence of who we are and how we came to be becomes increasingly obscure. Recently, thoughts of my father crystallized when my dear friend of many decades paid tribute to his own father at a museum dedication. His father had been a member of the Ghost Army during World War II, a secretive unit designed to deceive the Germans with decoys and sound recordings, diverting attention from combat Allied forces. Their contributions remained classified for half a century, but were recently recognized by Congress, awarding the unit the Congressional Medal of Honor for their role in saving over 30,000 lives.

My father also served during World War II, as a traffic controller in the Army Air Force during the North African Campaign, directing air traffic against Rommel’s Nazi forces. Like many veterans, he rarely spoke of his wartime experiences. 

His life was characterized by self-sacrifice. Losing his father at a young age, he supported his mother by working as a soda jerk, scooping so much chocolate ice cream that he developed a lifelong aversion to it. He left for the war as a newlywed, uncertain if he would return to his bride.

After the war, he moved our family to Queens, to a housing development for returning GIs. I grew up in an environment where friends and family were always present. My father was dedicated to us; he attended Little League games, took us on vacations in the Catskills, and celebrated our academic and sports achievements. He never resorted to physical punishment; a word or a look from him was enough to keep us in line. He spent every Friday night with his mother-in-law, content with the close-knit family gatherings.

He was a pillar of the community. When our neighbor couldn’t repay a Mafia loan, my father used his own limited funds to save him from retribution. He volunteered at the local Credit Union, and when it was on the brink of closure, he took over and saved it. Despite his limited formal education, having grown up during the Great Depression, he excelled in banking and aspired to improve his position. He treated my friends and acquaintances with fairness and shared his hard-earned wisdom on navigating life’s challenges.

For half a century, he worked at a multinational textile company. Lacking a degree, his career advancement was limited, but his work ethic, fairness, and sense of responsibility were recognized, and he managed a division separate from the main headquarters. He supervised a diverse office with respect and fairness, never uttering a disrespectful word or racial epithet.

My father was my moral compass, teaching me right from wrong through his actions. Beyond providing for us, he imparted lessons on family, duty, respecting others, and “doing the right thing.” Over three decades have passed since his death, but his lessons remain with me.

This tribute is long overdue: “Thank you, Dad. I love you.”
