The Nature of Truth

Passage

What is truth? This question has echoed through centuries, challenging philosophers, scientists, and thinkers of every era. At first glance, truth might seem obvious—what is real, what can be proven, or what matches the facts. But the deeper one looks, the more complicated it becomes.

In ancient times, Greek philosophers like Plato believed in absolute truth—unchanging and eternal. To Plato, truth was not found through the senses, which could be deceived, but through reason and thought. His famous Allegory of the Cave describes people mistaking shadows for reality, suggesting that truth lies beyond what we immediately perceive.

Centuries later, during the Enlightenment, philosophers like Descartes and scientists like Newton emphasized reason, observation, and proof. Descartes famously declared, 'I think, therefore I am,' grounding truth in the certainty of one's own mind. Meanwhile, Newton’s laws sought truth through mathematical formulas and experimental evidence, marking a shift toward empirical thinking.

But even these ideas were later questioned. In the 20th century, thinkers like Einstein showed that truth could be relative. Time and space, once thought to be fixed, depended on perspective. In philosophy, postmodern thinkers argued that truth might be shaped by culture, language, and power. Rather than a single truth, there might be multiple viewpoints—each influenced by human experience.

Today, in an age of information and misinformation, understanding truth is more important—and more challenging—than ever. While science still relies on evidence, and ethics still seeks clarity, people must navigate competing claims and shifting contexts. Truth may not always be simple, but asking what it means—and how we know it—remains essential for any thoughtful society.
