Why did Socrates claim to know nothing? Does this contradict his teachings of logic, reason, and critical thinking?

Reality is stranger than fiction. Even when we rely on logic, reason, and critical thinking, the knowledge we painstakingly deduce from contemporary understanding—which will soon become part of the past—may or may not align with the shifting landscape of the future. It’s better to acknowledge our limitations and actively take part in the infinite game of life than to claim to be superhuman while performing as mere mortals.
