In the passage, the author emphasizes that while time itself moves forward, the thoughts and ideas of certain individuals can become permanently entrenched in the minds of others. This suggests that ideas have a lasting impact, even if time continues to progress and change everything else.
The quote highlights the power of ideas and memories that can linger indefinitely, shaping perceptions and experiences beyond the natural flow of time. It underscores how some beliefs or impressions can be "enquista" or fixed in people's minds forever, regardless of the passage of time.
