I wanted to connect this piece of stoic philosophy to a different domain. From a mathematical perspective, the idea that “what we do now echoes in eternity” can be related to the concept of Chaos Theory.

In summary, the theory suggests that a seemingly small and insignificant action or decision can have a significant and lasting impact on future events (sensitive dependence on initial conditions).

Our choices and actions can profoundly impact the future, no matter how small they may seem.
