Quote of the day by famous mathematician Pythagoras: 'The oldest, shortest words— yes and no — are those which require the most thought'

As the new year begins, we’re often faced with countless choices—big and small—that shape the direction of our lives. Ancient wisdom can guide us, even in 2026. Pythagoras, the Ionian Greek philosopher and mathematician, once reminded us that the simplest words, “yes” and “no,” often require the deepest thought. His insight challenges us to pause before committing, emphasising that decisions—no matter how brief the words—carry weight and meaning, both personally and professionally.

Pythagoras, who lived in ancient Greece, was not just a mathematician but a philosopher and polymath. He founded Pythagoreanism, a school of thought that influenced Plato, Aristotle, and the foundation of Western philosophy. Beyond his philosophical teachings, he made several mathematical and scientific contributions, including the Pythagorean theorem, Pythagorean tuning, and the identification of the five regular solids. He also studied proportions, the sphericity of the Earth, and recognised that the morning and evening stars were both Venus.

The quote “The oldest, shortest words—‘yes’ and ‘no’—are those which require the most thought” reflects the careful deliberation necessary before making decisions. Even though the words are brief, choosing when to agree or refuse demands reflection, clarity, and responsibility. It reminds us that commitment, consent, or refusal is rarely trivial.


Pythagoras was also the first known person to call himself a philosopher, meaning “lover of wisdom.” Among his philosophical contributions, he is best remembered for the concept of the transmigration of souls, or metempsychosis, which suggests that the soul is immortal and enters a new body after death. This teaching, alongside his mathematical achievements, shaped centuries of thought and demonstrates the interconnectedness of logic, ethics, and life philosophy.


Even as historians debate which discoveries truly originated with him versus his students or contemporaries like Hippasus and Philolaus, Pythagoras’s impact on science, mathematics, and philosophy remains enduring. His words continue to inspire careful reflection, showing that even in an age of speed and instant decisions, pausing before saying yes or no can make all the difference.
