In the quote from Joseph Conrad's work, the author expresses a sense of disillusionment regarding the universe and humanity's fate. He suggests that the vast complexities of existence, defined by elements like fire and mud, are not worth our concern. Instead, he emphasizes that contemplating humanity's ultimate demise in a cold and silent universe can lead to unbearable sorrow. Thus, grappling with these existential truths may prove fruitless.

Conrad argues that the pursuit of improvement, knowledge, and beauty could be seen as futile endeavors, ultimately leading to despair. He likens the effort to maintain appearances to worrying about one's attire in a world where no one can see. This notion underlines the idea that striving for virtue and progress is an exercise in vanity, particularly in light of the inevitable decline towards darkness and silence that awaits all. Through this perspective, Conrad challenges the reader to rethink the value of such pursuits in a seemingly indifferent universe.
