No, not specifically. TST does not adopt entelechy as a core term. It respects Aristotle’s insight, but TST uses the simpler distinction between potential and actual. That gives us the useful part without carrying over Aristotle’s full teleology or later vitalist baggage.

In Aristotle, entelechy points to a thing’s fulfilled actuality. It is what something becomes when its potential has been fully realized according to its nature. An acorn has the potential to become an oak; the mature oak is closer to its fulfilled form. In this sense, entelechy is not merely potential, and it is not merely process. It is potential brought into completed actuality.

The reason TST does not specifically adopt entelechy is that it can imply a built-in final purpose or destiny. TST does not need that. A newborn baby has the potential to become an adult human, but not a tiger. Reality sets boundaries on what is possible. Within those boundaries, conditions, time, choices, and actions help determine what becomes actual. That is enough.

In TST, potential and actual do the work. Potential means what can become real within the constraints of reality. Actual means what has become real. This applies to human development, ideas, ethics, science, and even abstractions like infinity. Potential matters, but actuality is where reality pushes back.
