Can We Have Properly Basic Beliefs? An Exploration of Reformed Epistemology
The question of what it means to justifiably hold a belief stands at the heart of much philosophical inquiry. Epistemology, the study of knowledge and justified belief, often grapples with the issue of basic beliefs—beliefs that are not inferred from other beliefs but are instead foundational to all our reasoning. Traditionally, such beliefs required strong justification, leaving little room for beliefs outside self-evident truths or obvious observations. Yet, in the latter half of the twentieth century, the rise of Reformed Epistemology challenged this orthodoxy, especially in relation to religious belief. This school of thought, most notably championed by Alvin Plantinga, argued that certain religious and non-religious beliefs can be “properly basic”—that is, rationally held without inferential evidence or argument.
This essay will explore the nature and significance of properly basic beliefs, how Reformed Epistemology redefines their scope, the role of religious experience in their formation, and the critical debates surrounding these ideas. In so doing, it will consider whether foundational beliefs, particularly about God, can really be rational without recourse to evidence, and examine the consequences for epistemology more broadly.

The Nature of Properly Basic Beliefs in Epistemology
A properly basic belief is one that serves as a starting point in our web of knowledge, not requiring justification from other beliefs. To borrow an everyday example, our belief in the existence of the external world or the reality of other minds is not arrived at by conscious inference. Rather, these are the certainties upon which further reasoning depends. For instance, I do not deduce that the sun exists each morning from elaborate premises—it is, instead, the kind of belief I take for granted as a bedrock for living and learning.Classical foundationalism, the dominant position from Descartes onwards, set stringent criteria for a belief’s proper basicality. Only those beliefs which are self-evident (“All bachelors are unmarried”), incorrigible (“I am experiencing pain”), or directly evident to the senses (“I see a tree before me”) were allowed to stand without further support. Descartes’ famous dictum, “Cogito, ergo sum” (“I think, therefore I am”), is perhaps the archetype: a belief so indubitably certain that, for the foundationalist tradition, it could ground an entire edifice of knowledge.
However, these strict requirements have faced forceful criticism. If every belief must ultimately be proven by another, an infinite regress looms—an unending chain of justifications which never comes to rest. On the other hand, if we permit no basic beliefs at all, knowledge itself seems impossible. This tension exposed the arbitrariness—and potential narrow-mindedness—of classical foundationalism, pressing some philosophers to search for a more flexible approach.

to Reformed Epistemology
Reformed Epistemology emerged as a response to these limitations. At its heart, it maintains that some beliefs can be properly basic without satisfying the demanding classical criteria—and that among these may be beliefs about God’s existence. Inspired by Christian reformers such as John Calvin, who suggested that humans possess a natural sense of the divine (sensus divinitatis), Reformed Epistemologists claim that belief in God need not always rest on argument or evidence to be rational.
The contemporary movement was largely shaped in the late twentieth century by philosophers such as Alvin Plantinga and William Alston. They extended the idea of properly basic beliefs to include a wider range: not just the obvious and indubitable truths of perception or reason, but also those that arise from cognitive faculties functioning as they are meant to. For instance, belief in the reality of the past, the existence of other minds, and even the reliability of memory straddle a curious line—they are central to how we live, yet difficult to justify to a hardline sceptic.
Thus, Reformed Epistemology’s innovation is to broaden the class of beliefs that are accepted as properly basic. These are not arbitrary, but are subject to whether the belief results from cognitive faculties operating correctly in an appropriate context.

Religious Experience as Foundation for Basic Belief
Religious experience is often invoked by Reformed Epistemologists as prime evidence of properly basic belief’s expanded scope. Philosophers and theologians from various traditions have noted the unique character of such experiences—frequently intense, sometimes brief, but always leaving their mark on those who report them. Perhaps the British poet and essayist Thomas Traherne captured something of this when he described spiritual insight as “exceeding wonder, unspeakable delight.”Rudolf Otto, a German scholar but much discussed in British philosophical circles, introduced the category of the “numinous”: an experience of the ineffable, mysterious, and overwhelming “other”. These encounters resist easy description. They may be “noetic” (imparting knowledge), “transient” (fleeting yet profound), “ineffable” (beyond words), and “passive” (coming unbidden—the agent seemingly acted upon, rather than acting). Such qualities are familiar to anyone who has studied accounts in William James’s “The Varieties of Religious Experience”, a text that has influenced generations of philosophy students in the UK.
For Reformed Epistemologists, the immediacy and force of religious experience provide a foundation for properly basic belief in God. If encountering God is as direct and profound (though perhaps less consistent) as perceiving a tree outside the window, then belief in God could be seen as rational even in the absence of argumentative support. The experience itself functions epistemically, not just emotionally.

Alvin Plantinga’s Contribution: Properly Basic Beliefs and Warrant
Alvin Plantinga’s work is central to the development of Reformed Epistemology within contemporary analytic philosophy. Evidentialism—the view that a belief is only justified if backed by sufficient evidence—has long held sway. Plantinga, however, argues that evidentialism is not only too restrictive, but self-defeating: its own basic claim is not grounded in evidence but is presupposed.He draws an analogy with beliefs in other minds or the external world; we never demand empirical proof for these, yet they remain reasonable to hold. For Plantinga, belief in God is similarly “properly basic” when it arises from cognitive faculties functioning as intended in an appropriate setting.
In developing his account, Plantinga introduces the concept of “warrant”—that which transforms true belief into knowledge. Warrant, in his model, requires not only that our cognitive faculties are functioning properly, but that they are doing so in the sort of environment for which they were designed, and with the aim of truth.
Everyday examples help to illuminate the point: I remember having tea with a friend yesterday. I believe this not because I have amassed evidence, but because my memory operates reliably and I have no reason to think I am deceived. Similarly, my belief that others possess minds like mine is not deduced from behaviour, but forms a foundational assumption without which life would be unliveable. If, as Plantinga suggests, a sensus divinitatis exists and is working as it should, then belief in God, too, might be warranted in the absence of countervailing defeaters.

Critical Evaluation of Reformed Epistemology
Reformed Epistemology addresses the impasses of traditional epistemology with notable strengths. It provides an elegant escape from the threat of infinite regress, treats religious conviction respectfully, and validates the integrity of beliefs that resist reduction to facts or logical arguments.However, these very strengths have drawn criticism. If belief in God is properly basic, could not any belief—however bizarre—claim the same status? The so-called “Great Pumpkin Objection” (after Charles Schulz’s comic strip) asks whether belief in fairies, ghosts, or any other entity could also be classed as properly basic without evidence.
There is also the issue of conflicting religious experiences. Within the UK and elsewhere, adherents of myriad religions claim foundational revelations, often incompatible with each other. How are we to distinguish between experiences that genuinely confer knowledge and those which do not?
Reformed Epistemologists have offered various responses. First, they maintain that cognitive faculties must be functioning correctly in the right environment—a safeguard against gullibility. Second, beliefs must be immune to “defeaters”, reasons which would undermine their warrant. Third, they urge a kind of epistemic humility, recognising that not all rational beliefs admit of proof, and that our cognitive limitations mean some beliefs must be taken as starting points.

Broader Epistemological Implications
The shift from classical foundationalism to a Reformed approach has profound consequences for philosophy in general. It suggests that rationality need not always demand evidence and that belief can sometimes be trusted on the reliability of our faculties—provided they function correctly in their “epistemic environment”. This undermines radical scepticism, especially scepticism about the rationality of religious belief.Within the philosophy of religion, Reformed Epistemology has revitalised debate, moving beyond the sterile proofs and counter-proofs which dominated nineteenth and early twentieth-century argument. It grants religious believers space to assert that their faith can be justified without descending into blind fideism.
Moreover, the model prompts us to reconsider whether other types of knowledge—moral truths, aesthetic judgements, trust in memory—also depend on properly basic beliefs, suggesting a more nuanced and humane epistemology.

Conclusion
Reformed Epistemology challenges the garden walls of classical evidentialism, proposing a richer and perhaps more honest account of how beliefs, especially religious ones, might be rational without recourse to inferential support. By highlighting the role of religious experience, the reliability of cognitive faculties, and the necessity of foundational beliefs, thinkers like Alvin Plantinga have significantly reshaped debates in epistemology.Nonetheless, the approach is not without controversy. The difficulties of demarcating warranted from unwarranted basic beliefs, and adjudicating between competing claims, remain very much alive. As philosophy students and scholars continue to push at these boundaries, Reformed Epistemology stands as both a challenge to rigid evidentialism and an invitation to reconsider what it means to know.
Further inquiry might fruitfully focus on devising more precise criteria for distinguishing genuine from pseudo-religious experience, or exploring the implications for non-religious foundational beliefs. In doing so, philosophy continues its perennial task: wrestling with the nature of belief, justification, and the limits of human reason.
