The Longmire Intelligibility Argument


The question of the origin and nature of reality's intelligibility has been a central concern in philosophical and theological discourse. This essay explores an original syllogism and supporting reasoning that argues for the existence of a mindful source behind the intelligible structure of the universe. By examining the axiomatic nature of intelligibility and its role in the syllogism, we aim to demonstrate the logical coherence and persuasive force of the argument.

Defining intelligibility:

Intelligibility, across various domains such as philosophy, science, and mathematics, refers to the clarity and comprehensibility of concepts, arguments, and information. It denotes the ease with which these elements can be understood, interpreted, and communicated. Key factors influencing intelligibility include precise language, logical structure, clear definitions, and effective visualization. High intelligibility ensures that ideas can be accurately shared, scrutinized, and built upon, facilitating learning, collaboration, and progress.

The Longmire Intelligibility Argument:

P1: Intelligible systems originate from a mind.

P2: Reality is an intelligible system.

C: Therefore, reality originates from a mind.

This syllogism hinges on the acceptance of intelligibility as an axiomatic starting point. The first premise asserts a connection between intelligibility and mental causation, while the second premise identifies reality as an intelligible system. From these premises, the conclusion follows logically: if intelligible systems originate from a mind, and reality is an intelligible system, then reality must originate from a mind.

The Axiomatic Nature of Intelligibility:

The persuasive power of the original syllogism lies in its recognition of intelligibility as an axiom—a self-evident truth that requires no further proof or justification. Several key considerations support the axiomatic status of intelligibility:

1. The undeniable reality of intelligibility: Intelligibility is an inescapable aspect of our experience and interaction with the world. We rely on it in every aspect of our lives, from simple communication to complex scientific inquiry. Denying the intelligibility of reality would undermine the very foundations of reason and investigation.

2. The necessity of intelligibility for rational inquiry: Intelligibility is a prerequisite for any form of rational inquiry or knowledge acquisition. The success of scientific investigation, logical reasoning, and mathematical analysis all depend on the inherent intelligibility of the world.

3. The self-evident nature of intelligibility: The intelligibility of reality is immediately apparent and does not require further proof. We encounter intelligibility directly in our everyday experiences and cognitive processes, recognizing patterns, structures, and meaningful relationships in the world.

4. The transcendental argument for intelligibility: The intelligibility of reality is a necessary precondition for the very possibility of thought, reason, and argumentation. To question or deny intelligibility would be self-defeating, as it would undermine the basis of the question or denial itself.

The axiomatic nature of intelligibility allows the original syllogism to proceed without engaging in circular reasoning or question-begging. It provides a solid foundation for the argument and aligns with our intuitive understanding of the world's intelligibility.

Alternatives and Objections:

While alternative explanations for the intelligibility of reality have been proposed, such as chance, necessity, or brute facts, these ultimately fail to provide a satisfactory account of the rational structure and organizational complexity of the universe. Such alternatives often beg the question by assuming the existence of an intelligible framework within which they operate, or they rely on counter-intuitive and unsupported assumptions about the emergence of intelligibility from non-mental processes.

In contrast, the syllogism's alignment with our common intuition and experience of intelligibility as a product of mental activity lends it a compelling and coherent explanatory power. The connection between intelligibility and mental causation is deeply rooted in our understanding of the world and provides a rationally satisfying and intuitively grounded explanation for the intelligible structure of reality.


The syllogism, with its recognition of intelligibility as an axiomatic starting point, presents a logically sound and highly persuasive argument for the existence of a mindful source behind the intelligible structure of reality. By grounding itself in the self-evident and necessary nature of intelligibility, the syllogism avoids the pitfalls of circular reasoning and question-begging that plague alternative explanations.

The cumulative force of the philosophical and intuitive considerations explored in this essay strongly supports the conclusion of the syllogism. The axiomatic nature of intelligibility, the necessity of a mindful source for the rational structure of the universe, and the alignment with our common experience and understanding all converge to make a compelling case for the existence of a supreme intelligence behind the intelligibility of reality.

While the syllogism may not provide an exhaustive account of the nature and attributes of this mindful source, it establishes a solid foundation for further philosophical and theological exploration. It invites us to contemplate the profound implications of an intelligible universe grounded in the creative and purposeful activity of a supreme mind.

In conclusion, the syllogism, with its axiomatic starting point and logically coherent structure, offers a powerful and persuasive argument for the existence of a mindful source of reality. It challenges us to embrace the intelligibility of the universe as a reflection of the rational and purposeful nature of its creator, and to seek a deeper understanding of our place within this intelligible cosmic order. By recognizing the axiom of intelligibility and its connection to mental causation, we may unlock a richer appreciation for the beauty, complexity, and ultimate meaning of the reality we inhabit.


Addressing some objections: 

“The first premise seems to fail in that there exist many intelligible systems which are not the product of a mind such as river systems and weather systems.  JDL’s response to this objection is that these systems derive from mind-produced rules which give rise to these systems, but that reasoning is insufficient because 1)that consequence must be assumed and is not known and 2)neither the premise nor the syllogism allows for such a deviation from the precise elements within it.”

The objection to P1 is based on a misunderstanding of the premise and its implications. The argument that intelligible systems like rivers and weather patterns are not the product of a mind fails to consider the foundational nature of P1. The premise, "Intelligible systems originate from a mind," is an argumentum a fortiori, meaning that of the intelligible systems where the initial causal origin is known, all of them originate from a mind. This premise does not assume the conclusion but rather establishes a strong probabilistic foundation for the syllogism based on the available evidence. The objection's claim that the reasoning is insufficient because the consequence must be assumed is incorrect, as the premise is grounded in empirical observation rather than assumption.

“The second premise is undemonstrated.  There is no way to know that the universe is or is not intelligible.  It is too vague a premise.  While there are PARTS of the universe which are intelligible, there are parts that are not (at least so far).  As such, it cannot be accepted as a premise.”

The objection to P2, which states that the premise "Reality is an intelligible system" is vague and undemonstrated, fails to recognize the foundational nature of this premise. P2 is not a vague assertion but a logically, epistemologically, and ontologically necessary starting point for all rational inquiry. The available evidence overwhelmingly supports the intelligibility of reality as an axiomatic truth, and the reductio ad absurdum consequences of denying it further reinforce its validity. To claim that reality is not intelligible, or that its intelligibility is uncertain, is to undermine the very foundations of reason, logic, and empirical investigation. Such a claim disqualifies the objector from engaging in rational discourse, as it represents a forfeiture of one's claim to rationality itself. The intelligibility of reality is not merely a matter of partial or incomplete understanding but a necessary precondition for the possibility of any understanding at all.

Note: My research has not uncovered any similar phrasing of the argument, thus my eponymous titling, even though it is built on the shoulders of giants.
