Voluntariness refers to the quality of actions or decisions stemming from an individual's will, marked by conscious intent and self-determination. This concept has been examined through various perspectives, from Saint Thomas Aquinas, who associated it with both internal and external actions directed by reason and will, to Chapman Cohen, who observed that many essential life functions are only partially voluntary.
G. A. Johnston focused on self-imposed moral obligations, while Madame Guizot viewed voluntariness as a divine calling to purposefully embrace one’s designated role. These viewpoints together highlight voluntariness as a complex interaction between autonomy, intentionality, and ethical duty, connecting philosophical, theological, and psychological fields.
