James McCosh, The Scottish Philosophy: Biographical, Expository, Critical, from Hutcheson to Hamilton (1875).
This book is not just a history. It is a strategic articulation and defence of the Scottish philosophical view of common sense realism that has come to be identified with the name of Thomas Reid. For those who are interested in historical theology, especially in the Reformed tradition, this volume is of special interest. My aim in this post is not to describe its contents, but to analyse its main contentions in order to demonstrate that common sense realism is a decisive move away from historic Reformed theology.
The central shift comes in the articulation of a new principium cognoscendi. The Scottish project, as McCosh proudly defines it, is a methodological revolution with profound metaphysical consequences. The new method appeals to an induction from consciousness. Reformed Scholasticism began with divine revelation as the principium cognoscendi. Human reason, though a gift, is a ministerial tool operating within a fallen, analogical framework. Theology is the "queen of the sciences." The Scottish Philosophy begins with empirical observation of the human mind via consciousness. As McCosh states: "the human mind is to be studied exclusively by the method of observation." Now it is possible to draw all the laws of mental philosophy "from the observations of consciousness." McCosh celebrates this as progress.
After the central shift McCosh announces a crucial synthesis. Through induction, we discover "principles which are prior to and independent of experience." These are to be found "in the very constitution of the mind." It is even claimed that they have "the sanction of the Author of our nature." Reid's "common sense," Stewart's "fundamental laws," and Brown's "intuitions" are now raised to the level of "divine revelation." This contrasts with the Reformed View of "First Principles." The first truth is the existence and trustworthiness of the self-revealing Triune God. Innate ideas and the sensus divinitatis are corrupted by sin and insufficient for saving knowledge. They point to a need for special revelation. The Scottish school has effectively sanctified man's natural faculties. The "constitution of the mind" is now seen as reliably designed by God to give direct, trustworthy access to reality. The noetic effects of sin are minimised to correctable errors in reasoning, not a principial distortion of the knowing faculty itself.
This leads to a dynamic new view of human knowledge. Man's mental constitution provides self-evident, necessary, universal principles. There is no place for the old Reformed Scholastic distinctions between God's knowledge and man's knowledge. We do not need a special revelation to know how to know; our natural constitution tells us. These universal principles become the common ground for all rational persons, the believer and the sceptic alike. As a trustworthy revelation of God they can be used to build up an understanding of things "as they are," which then forms the basis for a rational defence of Christianity.
McCosh distinguishes the Scottish "inductive discovery of a priori principles" from the "dogmatic" or "a priori speculation" of older systems. He is critical of a deductive, syllogistic method and links this older method to pre-scientific "theosophies" and "scholastic times." This must include the structure of Reformed theology, which begins with the principium of Scripture and systematically deduces doctrines from it. Such "systems" are dismissed as pre-scientific dogmatism. In McCosh's narrative, the Scottish school represents the Enlightenment's application of the scientific method to the mind, finally freeing philosophy from outdated modes of thought.
This reverses the order of inquiry. Instead of starting with the doctrine of God (theology) to understand knowledge (epistemology), you start with an analysis of the knowing mind (epistemology) to determine what you can say about reality (theology). This is the distinctive feature of Enlightenment philosophy as over against the Reformed Scholastic commitment to Scripture.
According to McCosh the Scottish philosophy solidifies a dualistic ontology of "mind" and "matter" as two distinct substances, both known by their respective "senses" (internal and external). This replaces the richer, hierarchical Reformed ontology of Creator and creature, where both mind and matter are created as contingent realities under God's sovereign control. The primary metaphysical divide is no longer between the Infinite and the finite, but between thinking substance and extended substance.
In this new system, where does special revelation fit? McCosh gives a reverential acknowledgment at the end: the Scottish philosophy is a "bulwark in philosophy, morals, and theology." But note the order and the role: the Scottish philosophy of common sense is the bulwark for theology. Revelation is no longer the source and judge of philosophy; it is a supplementary body of truth that must be compatible with the foundational truths discovered by the universal "philosophy of consciousness." Theology becomes a tenant in a house built by philosophy.
McCosh was not naive. He saw the tension but he celebrated it: "Let it be their claim, that if they have not discovered all truth, they have discovered and settled some truth-- while they have not promulgated much error." The value of the Scottish philosophy, for McCosh, is its utility as a "breakwater to resist the assaults of scepticism." This was Reid's original goal: save Christian belief from Hume by making the mind's design logically prior to critical attacks. But at what price? Special revelation has been removed from the principium so as not to promulgate "much error."
That is the basic problem with apologetics. It is not what you know, but what you can show. What can you prove in this court of law where man stands as a judge of God? Not very much, it would appear. The Reformed Scholastics had the distinct advantage of bringing out all the claims of truth from God Himself as revealed in holy Scripture. The new philosophy of common sense realism is a poor replacement.
