Doctrine of the Will

In Short

This rigorous philosophical treatise defends the doctrine of human liberty against the prevailing deterministic arguments of the mid-nineteenth century. By analyzing the mental faculties—the intelligence, the sensibility, and the will—the text dismantles the "Necessitarian" view that human actions are merely inevitable responses to the strongest external motives. It serves as a foundational defense of moral agency, arguing that if humans are not truly free to choose, the concepts of sin, virtue, and divine justice lose all coherence. It remains a vital document for understanding the intellectual landscape of nineteenth-century American theology.

The Story

The inquiry begins by establishing the necessity of a precise mental science. The central conflict involves a clash between two competing views of the human soul: the Necessitarian school, which views the will as a passive engine driven by external motives, and the author’s own stance, which posits that the will possesses an inherent, self-determining power. The argument proceeds through a systematic deconstruction of the idea that the will always tracks the "greatest apparent good" or the "strongest desire." If that were true, the author contends, one could not account for self-denial or the genuine struggle of conscience, where an individual consciously chooses against their own strongest impulses.

As the argument unfolds, it addresses the most formidable challenge to free will: the nature of divine prescience. The author argues that God’s foreknowledge does not create a chain of causality that enslaves human action. Instead, he asserts that God foresees free acts precisely as they are—as free acts—rather than as inevitable outcomes of prior states. He maintains that human beings inhabit a world where their choices hold genuine weight, and this freedom is the only condition under which moral obligation can exist.

The narrative of the argument then pivots toward the practical implications of this liberty. If the will is the seat of moral agency, then "intentions" are the primary subjects of praise or blame. The author argues that external actions or emotional states are only significant insofar as they flow from these underlying volitional choices. By defining holiness as a voluntary conformity to perceived obligation, he strips away the possibility of "mixed" moral states; a person either intends to live in accordance with duty or they do not.

The work culminates in a vision of the human soul in relation to the Divine. Rather than seeing human freedom as a threat to God's sovereignty, the author suggests that liberty enhances it. He posits that a government of free agents, who choose to act in accordance with moral law, reflects a higher order of divine wisdom than a system of mechanical necessity. The journey concludes with an invitation to the reader to embrace a life of "filial dependence," where the knowledge of one's own freedom—and the constant presence of the "idea of duty"—leads to a state of spiritual peace. The final takeaway is that while the mysteries of the universe remain, the fundamental responsibility for one's moral character rests squarely upon the individual.

How It Unfolds

The foundational inquiry The author establishes the importance of distinguishing between theology and mental philosophy. He warns that failing to rely on clear psychological principles when interpreting scripture leads to a "labyrinth of error."

Defining the terms The text introduces the core dichotomy: Liberty versus Necessity. These are presented as universal categories, implying that every human action must fall into one of these two relations.

Challenging the Necessitarians The author systematically critiques the idea that motives act as efficient causes of the will. He points out the absurdity of requiring a person to act differently when the theory of necessity dictates that only one path is possible.

Addressing divine prescience A critical section addresses the tension between God’s foreknowledge and human choice. The argument is made that foreknowledge of a free act does not, in itself, render that act unfree.

Establishing moral obligation The focus shifts to the "intentions" of the will. The argument establishes that because we are only responsible for what we choose, moral character must be judged by our ultimate governing purpose.

A summary of the human condition The final chapters bridge the gap between abstract philosophy and spiritual life. The author concludes that the awareness of our own liberty and duty should naturally lead to a life of humble, dependent prayer.

The People

The book features the author as the primary voice of reason, guiding the reader through complex psychological terrain with an analytical tone. He frequently interacts with the ideas of his contemporaries—specifically "Necessitarians" like President Day and Edwards—who represent the intellectual opposition. These figures are not characters in a narrative sense, but rather embodiments of a worldview the author seeks to correct.

The "Necessitarian" is the primary adversary, a thinker who views human action as a product of external, causal chains. The author treats them with intellectual respect but insists that their logic leads to "horrid tyranny," as it would imply that God creates sinful natures and then punishes humans for them. Then there is the "Impartial Spectator," a figure representing the reader’s own common sense. The author appeals to this spectator to recognize the internal contradiction of believing in both divine justice and human necessity. Finally, the "Individual" emerges as the central figure of the study—a moral agent endowed with the "tremendous power" to choose. This individual, whether a peasant or a philosopher, is burdened with the "idea of duty" and must ultimately navigate the path between the "guardian angel" of moral obligation and the "avenging fiend" of failed responsibility.

In Its Own Voice

Regarding the nature of human agency:

"Not man alone, all rationals Heaven arms with an illustrious, but tremendous power, to counteract its own most gracious ends; and this, of strict necessity, not choice."

Regarding the logical consequence of the Necessitarian view:

"To motives, which of course exist independently of the Divine Will, we must ascribe the origin of all created existences."

Regarding the finality of moral choice:

"If we conceive an individual to yield a voluntary conformity to moral obligations of every kind, to the full extent of his present capacities, it is impossible for us to conceive that he is not now doing all that he really ought to do."

What It's Really About

At its heart, this book is an investigation into the nature of human accountability. It asks: Can a person be truly responsible for their actions if those actions are merely the result of prior causes? The author’s argument is a defense of the "doctrine of liberty," not as a license to do as one pleases, but as a necessary condition for moral existence. The central themes involve the interplay between the intelligence, the sensibility, and the will, and how these internal faculties shape our moral character. Ultimately, the book seeks to reconcile the existence of a sovereign, omniscient God with the undeniable human consciousness of being free, arguing that a moral universe is impossible without the freedom to choose between good and evil.

Why Read It Today

Readers who enjoy the intense, disciplined logical arguments of nineteenth-century American intellectual life will find this book deeply rewarding. It is not an easy read; the prose is dense, formal, and steeped in the theological and psychological vocabulary of the 1840s. One must be prepared for long, winding paragraphs that demand slow, careful digestion.

However, the experience of reading it is akin to witnessing a master builder dismantle a structure stone by stone. For those interested in the history of ideas—particularly the development of the American conscience—this work offers a window into how thinkers of that era grappled with the fundamental tensions between determinism and free will. Its insistence that our "intentions" define our moral worth remains a provocative challenge to modern psychological determinism. While the book carries the period’s specific theological concerns, the underlying question—Are we the authors of our own character?—remains as urgent today as it was in 1845. It is a demanding, serious-minded book for those who want to understand the deep-rooted foundations of personal responsibility, and it rewards the patient reader with a clearer understanding of the "over-shadowing idea of duty."
