Yes, this statement remains relevant. Let me explain why by explaining a bit about the history of Greek philosophy.
One of the earliest of Greek philosophers, Pythagoras (in the 6th century BC), is thought to have coined the term "philosopher." The report is that Pythagoras did not want to claim to be a wise man who already had great wisdom, but that he was a "lover of wisdom" who sought to be wise. In Greek, "philos" is a word for "love" and "sophia" is the word for wisdom. So a "philosopher" is a "lover of wisdom."
The great philosopher Socrates (5th century BC) was famous for saying, "The unexamined life is not worth living." He saw the goal of his life as constantly seeking wisdom -- and that what truly made him wise was recognizing how little he truly knew with certainty.
The examples of intellectual curiosity and eagerness to grow in wisdom remain relevant examples for us in the modern world. We do well always to be examining our thinking, our pattern of life, our conduct toward others, our relationships in society, our hopes for the future. Without such ongoing self-examination, we cannot be or become wise.
