Scottish common sense realism, also known as the Scottish school of common sense, [1] is a realist school of philosophy that originated in the ideas of Scottish philosophers Thomas Reid, Adam Ferguson, James Beattie, and Dugald Stewart during the 18th-century Scottish Enlightenment. Reid emphasized man's innate ability to perceive common ideas and that this process is inherent in and interdependent with judgement. Common sense, therefore, is the foundation of philosophical inquiry. Though best remembered for its opposition to the pervasive philosophy of David Hume, Scottish common sense philosophy is influential and evident in the works of Thomas Jefferson and late 18th-century American politics. [2] [3]
The Scottish School of Common Sense was an epistemological philosophy that flourished in Scotland in the late 18th and early 19th centuries. [4] Its roots can be found in responses to the writings of such philosophers as John Locke, George Berkeley and David Hume, and its most prominent members were Dugald Stewart, Thomas Reid, William Hamilton and, as has recently been argued, Thomas Carlyle. [5] [6] Philosophically, Scottish Realism served as a rebuttal to scepticism while keeping with the influential teachings of Isaac Newton and Francis Bacon. [4] While largely understated for many years, [4] the influence it had on philosophers elsewhere in Europe, not to mention in the United States, is of a considerable magnitude.
One central concern of the school was to defend "common sense" against philosophical paradox and scepticism. It argued that common-sense beliefs govern the lives and thoughts even of those who avow non-commonsensical beliefs and that matters of common sense are inherent to the acquisition of knowledge. The qualities of its works were not generally consistent; Edward S. Reed writes, e.g., "[Whereas] Thomas Reid wished to use common sense to develop philosophical wisdom, much of this school simply wanted to use common sense to attack any form of intellectual change." [7]
The Scottish School of Common Sense was founded by Reid in opposition to Descartes's Theory of Ideas. [8] But the epistemology of sense experience led John Locke and David Hume to a skeptical philosophy that realists found absurd and contrary to common experience. Thus Hume and his sceptical argument would serve as the primary foil to the development of Reid's philosophy. Under the tutelage of George Turnbull, Reid embraced the tenets of Providential Naturalism and its four interconnected tenets; using these as the basis for his refutation of the theory of ideas. [8] Reid painstakingly developed his treatise An Inquiry into the Human Mind on the Principles of Common Sense over the course of 40 years, often seeking the input of his contemporary philosophers within the Scottish Enlightenment including Hume. [8]
Reid articulated the basic principle of Common Sense Realism:
Scottish Common Sense Realism is rooted in Aristotelian thought and advocates an empirical and scientific philosophy wherein trust of our senses is implicit and necessary. [10] : 148 The principles of common sense are fundamental to our accumulation of knowledge of both metaphysical and physical constructs. [4] However, observation alone cannot account for all knowledge, and truth can be garnered by reflection. [10] : 149 In Reid's own words:
Essential to first principles, faculties, or mental powers, perform the act of perception and conception (Leher 784). The intellectual faculties support a wide variety of mental events. Acts of conceiving are set in many of them (Nichols and Yaffe). Examples of conception include judging there is a door in front of me, imagining there is a door in front of me, or reasoning that all doors have handles (Nichols and Yaffe). "Faculties are all fallible" as there is evidence of our faculties and senses but not of objects we conceive (Leher 785). But, "we trust them whether we choose to or not" since they always prevail in daily life (Leher 786). All Reid's philosophy depends on not fallacious faculties. Senses are an extension of the faculties; they produce conceptions qualities (like how a smell suggests the existence of an object) and ground our beliefs (Nichols and Yaffe 45). Freedom is another natural conviction from faculties, which is preloaded and irresistible as first principles prove. Faculties are "the foundation of true philosophy, science, and practical life, and without them we shall lead ourselves into the coalpit of skepticism and despair." (Leher 787).
The school taught that every person had ordinary experiences that provided intuitively certain assurance of a) the existence of the self, b) the existence of real objects that could be seen and felt; and c) certain "first principles" upon which sound morality and religious beliefs could be established. These principles laid the foundation for Reid's influential theory of perception.
In practice, philosophers of the Scottish school offered scientific explanations to historical events and advocated an unprejudiced and inter-disciplinary approach to education, free from religious and patriotic biases. [12] [13]
Thomas Reid and Dugald Stewart offered related theories of perception rooted in Scottish Common Sense Realism. According to Nicholas Wolterstorff of Yale University, Reid's philosophy can be non-contentiously reduced to four basic precepts:
Dugald Stewart's theory of perception acknowledges a great influence from Reid whose philosophy he termed "fundamental laws of belief." [15] However, Stewart proffered a more moderate approach to realism and his theory of perception emphasized the utility of the senses. [15]
Common Sense Realism not only influenced Scottish thought in the 19th century, it had a major influence as well in France, the United States, and other countries. Victor Cousin (1792–1867) was the most important proponent in France. Reidian thought was the "orthodox philosophy of colleges and universities" [4] in the early 18th century and provided an intellectual bedrock for the Age of Enlightenment. [4]
Common Sense Realism swept American intellectual circles in the 18th century. [17] : 181 Reid's philosophy was pervasive during the American Revolution and served as a stabilizing philosophical influence. [17] : 180 Hailed by some as the "father of modern psychiatry," [17] : 173 Benjamin Rush's tutelage at the University of Edinburgh imbued him with strong realist tendencies which influenced much of his scientific and political work including his moral opposition to slavery. [17] : 174 Evidence of the influence of Scottish Common Sense realism can readily be found in the philosophy of both Thomas Jefferson and John Adams. Adams compared the contributions of Dugald Stewart favorably to works of Aristotle and René Descartes. [17] : 170 Scotsman and signer of the Declaration of Independence, John Witherspoon presided over Princeton University; students under his tutelage included 12 state governors, 55 delegates to the Constitutional Convention and future president James Madison. [17] : 171 His education at the University of Edinburgh made him a strong proponent of the Scottish Enlightenment and Realism. James McCosh (1811–94) continued the influence of Scottish Realism at Princeton when he became president of the university in 1868, reviving its influence as a major stronghold of the movement. Noah Porter (1811–92) taught Common Sense realism to generations of students at Yale.
Scottish Realism greatly influenced conservative religious thought and was strongest at Princeton Seminary until the Seminary moved in new directions after 1929. The Princeton theologians built their elaborate system on the basis of "common-sense" realism, biblicism and confessionalism. [18] James McCosh was brought from Queen's College, Belfast, to Princeton College's Chair of Moral Philosophy and Presidency because of his book "The Method of Divine Government," a Christian philosophy that was precursory to Charles Darwin's "The Origin of Species" (1859). Several Princeton Theologians followed McCosh to adopt a stance of theistic evolution. It was his goal to develop Princeton as a Christian university in North America, as well as a forefront intellectual seminary of the Presbyterian Church. The faculty of the college and seminary included both evolutionary thinkers and non-evolutionary thinkers. Much evangelical theology of the 21st century is based on Princeton theology and thus reflects Common Sense Realism. [19] New Testament scholar Grant R. Osborne concludes that Scottish Common Sense Realism influenced biblical hermeneutics, that the surface level understanding of Scripture became popular, and individualistic interpretations abounded. [20]
David Hume was a Scottish philosopher, historian, economist, and essayist who was best known for his highly influential system of empiricism, philosophical skepticism and metaphysical naturalism. Beginning with A Treatise of Human Nature (1739–40), Hume strove to create a naturalistic science of man that examined the psychological basis of human nature. Hume followed John Locke in rejecting the existence of innate ideas, concluding that all human knowledge derives solely from experience. This places him with Francis Bacon, Thomas Hobbes, John Locke, and George Berkeley as an empiricist.
In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience and empirical evidence. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricists argue that empiricism is a more reliable method of finding the truth than purely using logical reasoning, because humans have cognitive biases and limitations which lead to errors of judgement. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. Empiricists may argue that traditions arise due to relations of previous sensory experiences.
The philosophy of perception is concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world. Any explicit account of perception requires a commitment to one of a variety of ontological or metaphysical views. Philosophers distinguish internalist accounts, which assume that perceptions of objects, and knowledge or beliefs about them, are aspects of an individual's mind, and externalist accounts, which state that they constitute real aspects of the world external to the individual. The position of naïve realism—the 'everyday' impression of physical objects constituting what is perceived—is to some extent contradicted by the occurrence of perceptual illusions and hallucinations and the relativity of perceptual experience as well as certain insights in science. Realist conceptions include phenomenalism and direct and indirect realism. Anti-realist conceptions include idealism and skepticism. Recent philosophical work have expanded on the philosophical features of perception by going beyond the single paradigm of vision.
Thomas Reid was a religiously trained Scottish philosopher best known for his philosophical method, his theory of perception, and its wide implications on epistemology, and as the developer and defender of an agent-causal theory of free will. He also focused extensively on ethics, theory of action, language and philosophy of mind.
The Scottish Enlightenment was the period in 18th- and early-19th-century Scotland characterised by an outpouring of intellectual and scientific accomplishments. By the eighteenth century, Scotland had a network of parish schools in the Scottish Lowlands and five universities. The Enlightenment culture was based on close readings of new books, and intense discussions which took place daily at such intellectual gathering places in Edinburgh as The Select Society and, later, The Poker Club, as well as within Scotland's ancient universities.
Théodore Simon Jouffroy, aka Simon Joseph Théodore Jouffroy, was a French philosopher.
Dugald Stewart was a Scottish philosopher and mathematician. Today regarded as one of the most important figures of the later Scottish Enlightenment, he was renowned as a populariser of the work of Francis Hutcheson and of Adam Smith. Trained in mathematics, medicine and philosophy, his lectures at the University of Edinburgh were widely disseminated by his many influential students. In 1783 he was a joint founder of the Royal Society of Edinburgh. In most contemporary documents he is referred to as Prof Dougal Stewart.
Francis Hutcheson LLD was an Irish philosopher born in Ulster to a family of Scottish Presbyterians who became known as one of the founding fathers of the Scottish Enlightenment. He was Professor of Moral Philosophy at Glasgow University and is remembered as author of A System of Moral Philosophy.
In philosophy of perception and epistemology, naïve realism is the idea that the senses provide us with direct awareness of objects as they really are. When referred to as direct realism, naïve realism is often contrasted with indirect realism.
Nicholas Paul Wolterstorff is an American philosopher and theologian. He is currently Noah Porter Professor Emeritus of Philosophical Theology at Yale University. A prolific writer with wide-ranging philosophical and theological interests, he has written books on aesthetics, epistemology, political philosophy, philosophy of religion, metaphysics, and philosophy of education. In Faith and Rationality, Wolterstorff, Alvin Plantinga, and William Alston developed and expanded upon a view of religious epistemology that has come to be known as Reformed epistemology. He also helped to establish the journal Faith and Philosophy and the Society of Christian Philosophers.
Philosophical realism – usually not treated as a position of its own but as a stance towards other subject matters – is the view that a certain kind of thing has mind-independent existence, i.e. that it exists even in the absence of any mind perceiving it or that its existence is not just a mere appearance in the eye of the beholder. This includes a number of positions within epistemology and metaphysics which express that a given thing instead exists independently of knowledge, thought, or understanding. This can apply to items such as the physical world, the past and future, other minds, and the self, though may also apply less directly to things such as universals, mathematical truths, moral truths, and thought itself. However, realism may also include various positions which instead reject metaphysical treatments of reality entirely.
George Campbell FRSE was a Scottish Enlightenment philosopher, minister, and professor of divinity. Campbell was primarily interested in rhetoric, since he believed that its study would enable his students to become better preachers. He became a philosopher of rhetoric because he took it that the philosophical changes of the Age of Enlightenment would have implications for rhetoric.
Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute; rather, it defuses confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.
The following outline is provided as an overview of and topical guide to metaphysics:
Newtonianism is a philosophical and scientific doctrine inspired by the beliefs and methods of natural philosopher Isaac Newton. While Newton's influential contributions were primarily in physics and mathematics, his broad conception of the universe as being governed by rational and understandable laws laid the foundation for many strands of Enlightenment thought. Newtonianism became an influential intellectual program that applied Newton's principles in many avenues of inquiry, laying the groundwork for modern science, in addition to influencing philosophy, political thought and theology.
Common sense is "knowledge, judgement, and taste which is more or less universal and which is held more or less without reflection or argument". As such, it is often considered to represent the basic level of sound practical judgement or knowledge of basic facts that any adult human being ought to possess. It is "common" in the sense of being shared by nearly all people. The everyday understanding of common sense is ultimately derived from historical philosophical discussions. Relevant terms from other languages used in such discussions include Latin sensus communis, Ancient Greek κοινὴ αἴσθησις, and French bon sens. However, these are not straightforward translations in all contexts, and in English different shades of meaning have developed. In philosophical and scientific contexts, since the Age of Enlightenment the term "common sense" has been used for rhetorical effect both approvingly and disapprovingly. On the one hand it has been a standard for good taste, good sense, and source of scientific and logical axioms. On the other hand it has been equated to conventional wisdom, vulgar prejudice, and superstition.
American philosophy is the activity, corpus, and tradition of philosophers affiliated with the United States. The Internet Encyclopedia of Philosophy notes that while it lacks a "core of defining features, American Philosophy can nevertheless be seen as both reflecting and shaping collective American identity over the history of the nation". The philosophy of the Founding Fathers of the United States is largely seen as an extension of the European Enlightenment. A small number of philosophies are known as American in origin, namely pragmatism and transcendentalism, with their most prominent proponents being the philosophers William James and Ralph Waldo Emerson respectively.
An Essay on the Nature and Immutability of Truth is a 1770 book about truth by the Scottish philosopher and poet James Beattie. His major work, the book enjoyed great success but angered the philosopher David Hume and has been criticized for Beattie's tendency to denounce his opponents.
Donald Cary Williams, usually cited as D. C. Williams, was an American philosopher and a professor at both the University of California Los Angeles and at Harvard University.
Scottish philosophy is a philosophical tradition created by philosophers belonging to Scottish universities. Although many philosophers such as Francis Hutcheson, David Hume, Thomas Reid, and Adam Smith are familiar to almost all philosophers it was not until the 19th century that the notion of 'Scottish philosophy' became recognized and highly regarded internationally. In the 20th century, however, this tradition declined as Scottish-educated philosophers left for England.
