The quote emphasizes the importance of observation over mere verbal testimony, suggesting that a witness's credibility is determined by their experiences rather than their words. It implies that personal experiences are valid, regardless of whether they are shared or hidden from others.
Furthermore, the quote highlights the idea that secrecy cannot erase past events. Even if someone chooses to conceal a truth, it remains a part of reality. This reflects a deeper understanding of the human experience, where unspoken truths still carry weight, and denial does not alter the past.
