Dynamis is a Greek word that translates to "power" or "force." In various contexts, it refers to the inherent ability or capacity of something to produce an effect or change. This concept is often explored in philosophy, physics, and even psychology, where it can describe the potential energy within systems or individuals. In ancient Greek philosophy, particularly in the works of Aristotle, dynamis is contrasted with "energeia," which means "actuality." While dynamis represents potential, energeia signifies the realization of that potential. This distinction helps in understanding how things can change or evolve over time, emphasizing the importance of both potential and actual states in various fields of study.
