Every action, including every choice by individuals, is part of an infinite chain, with no link necessarily being more or less important than every other link. The individual in making the choice is both determined and determiner. The individual, as part of innumerable different chains, evolves into something that emits energy in its own unique way, unknown and unknowable, as each individual has a unique history and organization. And so the uniqueness of the individual provides a unique link in each chain in which the individual participates that can influence the further evolution of the chain.
