Philosophy Day (Tetsugaku no Hi)

What Is Philosophy Day?

Every April 27th is "Philosophy Day." It marks the date in 399 BCE traditionally associated with the execution of the ancient Greek philosopher Socrates. Socrates taught the importance of "knowing that you know nothing" and the value of continuous self-reflection, and his thinking became a cornerstone of Western philosophy. This day is an opportunity to look back on his life and philosophy, and to reconsider the value of "thinking" itself.

The Origins and Background of Philosophy Day

Socrates engaged the citizens of Athens in dialogue, posing fundamental questions like "What is goodness?" and "What is justice?" His approach had a profound impact on society at the time. He was eventually charged with corrupting the youth and not believing in the city's gods, and after being sentenced to death, he refused to flee and is said to have died by drinking a cup of poison hemlock. His thought was carried forward by his student Plato and, in turn, by Plato's student Aristotle, laying the foundations of philosophy as a discipline.

Note that the date of April 27 is a conversion from the ancient Greek calendar, and there are differing views on the exact date.

• Origin: The traditional date of Socrates' death (399 BCE)
• Purpose: To reaffirm the importance of philosophical thinking
• Significance: An opportunity to think deeply about yourself and society
