About this quote
Socrates spoke these words at his trial in 399 BC, as reported in Plato's Apology. After being found guilty of impiety and corrupting the youth of Athens, he refused to propose exile or silence as an alternative to death, declaring that a life without philosophical inquiry would have no value. He was sentenced to death by drinking hemlock.
