This evocative line vividly captures the essence of human perseverance and denial in the face of perceived realities that may be illusions or manifestations of inner turmoil. The act of 'thrusting fists against the posts' suggests a desperate, forceful effort—possibly a metaphor for fighting against one's own fears, doubts, or inner demons. Despite the physical exertion and perhaps the futility of such struggles, the individual continues to insist on seeing the ghosts, symbolizing an unwavering belief or obsession with something potentially illusory or confronting. This tension between denial and acknowledgment often reflects broader themes of mental health, the human tendency to cling to perceived truths, or the desire to confront unresolved issues head-on.

Such imagery serves as a powerful reminder of the ways in which individuals grapple with their internal struggles. The ghosts could be literal apparitions, or they might represent memories, guilt, loss, or hidden truths that haunt a person’s mind. The persistence to see these ghosts despite physical resistance symbolizes an unyielding need to confront or understand one’s past, no matter how painful or futile the effort might seem.

On a broader scale, the quote invites reflection on how humans often cling to beliefs, fears, or perceptions that may not be grounded in reality, yet are deeply ingrained in their psyche. It speaks to the complex psychology of denial and acceptance, highlighting how sometimes resistance is futile, but the human spirit insists on continuing the fight. In literature and art, this theme is recurrent, reminding us of the importance of confronting our inner ghosts for growth or facing the consequences of avoidance.

Overall, this quote serves as a haunting yet evocative metaphor for perseverance in denial, the human struggle with inner torment, and the persistent quest to confront unseen truths.
