This quote reflects the existentialist belief that human beings are constantly evolving, changing, and growing. The phrase "He is always becoming" suggests that a person’s identity is not fixed or static, but rather is a fluid, ongoing process of transformation. This idea challenges the conventional notion of a stable, unchanging self, suggesting instead that we are perpetually in a state of becoming, defined by our actions, experiences, and choices.

The second part of the quote, "if it were not for the contingency of death, he would never end," introduces the concept of mortality as a defining aspect of human existence. It suggests that the only thing that puts a stop to this continuous process of becoming is death. This could be interpreted to mean that our potential for growth and change is limitless, only constrained by the finite nature of life.

In today’s world, this quote can be applied to personal development and self-improvement. It encourages us to see ourselves not as finished products, but as works in progress, always capable of change and growth. It emphasizes the importance of embracing change, rather than resisting it, and of recognizing our potential for continuous self-transformation.

This perspective can be empowering, as it suggests that we are not bound by our pasts, but are free to reinvent ourselves at any moment. It also underscores the value of life experience, suggesting that every experience, whether positive or negative, contributes to our ongoing process of becoming.

In terms of mortality, it is a reminder that our time is limited. This can motivate us to make the most of each moment, to seize opportunities for growth and change, and to live our lives to the fullest. It can also encourage us to view death not as a negation of life, but as a part of life that gives it urgency and meaning.
