When Jordan Peterson says that "nobody gets away with anything" and that it will all come back in some way, he is expressing a perspective on the idea of personal responsibility and the consequences of our actions. He suggests that our actions and decisions have repercussions, whether positive or negative, and that over time, these consequences can manifest in various aspects of our lives.
From Peterson's viewpoint, this concept is closely tied to the idea that individuals should take responsibility for their actions and be mindful of the potential effects they may have on themselves and others. He often emphasizes the importance of confronting and addressing one's shortcomings, mistakes, and past actions to foster personal growth and development.
This idea also aligns with some philosophical and psychological perspectives on accountability and the interconnectedness of actions and outcomes. It suggests that the choices we make have a way of reverberating through our lives and shaping our future experiences.
I can say that the concept of personal responsibility and the idea that actions have consequences are widely discussed and accepted in various philosophical, ethical, and psychological frameworks. Many people believe that being accountable for one's actions and making ethical decisions can contribute to a more fulfilling and harmonious life.
That said, the extent to which every action "comes back" in specific ways is a complex and nuanced topic, and individual circumstances can vary greatly. While taking responsibility for our actions is essential, life is also influenced by a multitude of external factors that may be beyond our control.
Ultimately, it is up to each person to consider their beliefs about personal responsibility, consequences, and how they choose to live their lives in light of these ideas.
