The quote reflects on the nature of opportunity and the inherent self-determination that comes with it. It suggests that throughout life, individuals face various changes and situations that challenge their moral compass. These experiences can sometimes lead one to act against their own principles, metaphorically describing the idea of appearing as a thief. This illustrates the complexities of human decisions and the impact of circumstances on personal integrity.

In Jaroslav Hašek's "The Good Soldier Švejk," these themes resonate with the experiences of the protagonist, who navigates the absurdities of war and society. The notion of self-determination is crucial, emphasizing that individuals ultimately shape their paths despite external influences. The quote serves as a reminder of the moral ambiguities that can arise as people pursue their goals amidst the inevitable changes of life.
