In John Updike's book "The Centaur," a quote reflects on the notion of agency and self-determination, suggesting that when all else fails, a person can still take drastic actions to assert control over their own destiny. The statement implies that even in dire situations, the act of choice remains, though it may lead to harmful consequences.

This perspective prompts readers to consider the lengths to which individuals may go when confronted with overwhelming challenges. The imagery of "shooting one's own two legs" serves as a metaphor for self-sabotage, highlighting the complexity of human behavior in moments of despair.
