Logical atomism

Logical atomism is a philosophical belief that originated in the early 20th century with the development of analytic philosophy. Its principal exponents were the British philosopher Bertrand Russell, the early work of his Austrian-born pupil and colleague Ludwig Wittgenstein, and his German counterpart Rudolf Carnap.[1]

The theory holds that the world consists of ultimate logical "facts" (or "atoms") that cannot be broken down any further. Having originally propounded this stance in his Tractatus Logico-Philosophicus, Wittgenstein rejected it in his later Philosophical Investigations (secs. 46–49, 91 and sec. 81).

The name for this kind of theory was coined in 1918 by Russell in response to what he called "logical holism"—i.e., the belief that the world operates in such a way that no part can be known without the whole being known first.[2] This belief is commonly called monism, and in particular, Russell (and G. E. Moore) were reacting to the absolute idealism dominant then in Britain and exemplified in works of F. H. Bradley and J. M. E. McTaggart.[2]

Origin

The term was first coined in a 1911 essay by Russell entitled "The Basis of Realism." However, it became widely known only when Russell gave a series of lectures in 1918 entitled "The Philosophy of Logical Atomism". Russell was much influenced by Ludwig Wittgenstein, as an introductory note explicitly acknowledges.

Russell and Moore broke themselves free from British Idealism which, for nearly 90 years, had dominated British philosophy. Russell would later recall in "My Mental Development"[3] that "with a sense of escaping from prison, we allowed ourselves to think that grass is green, that the sun and stars would exist if no one was aware of them".

Principles

Russell referred to his atomistic doctrine as contrary to the tier "of the people who more or less follow Hegel" (PLA 178).

The first principle of logical atomism is that the World contains "facts". The facts are complex structures consisting of objects ("particulars"). This he defines as "objects' relations in terms of atomic facts" (PLA 199) is a fact, either from an object with a simple property or from different objects, in relation to each other more easily. In addition, there are judgments ("beliefs"), which are in a relationship to the facts, and by this relationship either true or false.

According to this theory, even ordinary objects of daily life "are apparently complex entities". According to Russell, words like "this" and "that" are used to denote particulars. In contrast, ordinary names such as "Socrates" actually are definitive descriptions. In the analysis of "Plato talks with his pupils", "Plato" needs to be replaced with something like "the man who was the teacher of Aristotle".

In 1905, Russell had already criticized Alexius Meinong, whose theories led to the paradox of the simultaneous existence and non-existence of fictional objects. This theory of descriptions was crucial to logical atomism, as Russell believed that language mirrored reality.

Russell's principles

Bertrand Russell's theory of logical atomism consists of three interworking parts: the atomic proposition, the atomic fact, and the atomic complex. An atomic proposition, also known as an elemental judgement, is a fundamental statement describing a single entity. Russell refers to this entity as an atomic fact, and recognizes a range of elements within each fact that he refers to as particulars and universals. A particular denotes a signifier such as a name, many of which may apply to a single atomic fact, while a universal lends quality to these particulars, e.g. color, shape, disposition. In Russell's Theory of Acquaintance, awareness of these particulars and universals comes through sense data. Every system consists of many atomic propositions and their corresponding atomic facts, known together as an atomic complex. In respect to the nomenclature that Russell used for his theory, these complexes are also known as molecular facts in that they possess many atoms. Rather than decoding the complex in a top-down manner, logical atomism analyzes its propositions individually before considering their collective effect. According to Russell, the atomic complex is a product of human thought and ideation that combines the various atomic facts in a logical manner.

Russell's perspective on belief proved a point of contention between him and Wittgenstein, causing it to shift throughout his career. In logical atomism, belief is a complex that possesses both true and untrue propositions. Initially, Russell plotted belief as the special relationship between a subject and a complex proposition. Later, he amended this to say that belief lacks a proposition, and instead associates with universals and particulars directly. Here, the link between psychological experience – sense data – and components of logical atomism – universals and particulars – causes a breach in the typical logic of the theory; Russell’s logical atomism is in some respects defined by the crossover of metaphysics and analytical philosophy, which characterizes the field of naturalized epistemology.[4]

In his theory of Logical Atomism, Russell posited the highly controversial idea that for every positive fact exists a parallel negative fact: a fact that is untrue. The correspondence theory maintains that every atomic proposition coordinates with exactly one atomic fact, and that all atomic facts exist. The Theory of Acquaintance says that for any given statement taking the form of an atomic proposition, we must be familiar with the assertion it makes. For example, in the positive statement, “the leaf is green,” we must be acquainted with the atomic fact that the leaf is green, and we know that this statement corresponds to exactly this one fact. Along this same line, the complementary negative statement, “the leaf is not green," is clearly false given what we know about the color of the leaf, but our ability to form a statement of this nature means that a corresponding fact must exist. Regardless of whether the second statement is or isn't true, the connection between its proposition and a fact must itself be true. One central doctrine of Logical Atomism, known as the Logically Perfect Language Principle, enables this conclusion. This principle establishes that everything exists as atomic proposition and fact, and that all language signifies reality. In Russell’s viewpoint, this necessitates the negative fact, whereas Wittgenstein maintained the more conventional Principle of Bivalence, in which the states "P" and "Not (P)" cannot coexist.

Wittgenstein's principles

In his Tractatus Logico-Philosophicus, Ludwig Wittgenstein explains his version of logical atomism as the relationship between proposition, state of affairs, object, and complex, often referred to as “Picture theory”.[5] In view of Russell’s version, the propositions are congruent in that they are both unconvoluted statements about an atomic entity. Every atomic proposition is constructed from “names” that correspond to “objects”, and the interaction of these objects generate “states of affairs,” which are analogous to what Russell called atomic facts. Where Russell identifies both particulars and universals, Wittgenstein amalgamates these into objects for the sake of protecting the truth-independence of his propositions; a self-contained state of affairs defines each proposition, and the truth of a proposition cannot be proven by the sharing or exclusion of objects between propositions. In Russell’s work, his concept of universals and particulars denies truth-independence, as each universal accounts for a specific set of particulars, and the exact matching of any two sets implies equality, difference implies inequality, and this act as a qualifier of truth. In Wittgenstein’s theory, an atomic complex is a layered proposition subsuming many atomic propositions, each representing its own state of affairs.

Wittgenstein's handling of belief was dismissive, and reflects his abstainment from the epistemology that concerned Russell. Because his theory dealt with understanding the nature of reality, and because any item or process of the mind barring positive fact, i.e. something absolute and without interpretation, may become altered and thus divorced from reality, belief exists as a sign of reality but not reality itself. Wittgenstein was decidedly skeptical of epistemology, which tends to value unifying metaphysical ideas while depreciating the casewise and methodological inspection of philosophy that dominates his Tractatus Logico-Philosophicus.[6] Furthermore, Wittgenstein concerned himself with defining the exact correspondence between language and reality wherein any explanation of reality that defies or overburdens these semantic structures, namely metaphysics, becomes unhinged. Wittgenstein’s work bears the exact philosophical determinants that he openly admonished, hence his later abandonment of this theory altogether.

Differences between Russell's and Wittgenstein's atomism

At the time Russell delivered his lectures on logical atomism, he had lost contact with Wittgenstein. After World War I, Russell met with Wittgenstein again and helped him publish the Tractatus Logico Philosophicus, Wittgenstein's own version of Logical Atomism.

Although Wittgenstein did not use the expression Logical Atomism, the book espouses most of Russell's logical atomism except for Russell's Theory of Knowledge (T 5.4 and 5.5541). By 1918 Russell had moved away from this position. Nevertheless, the Tractatus differed so fundamentally from the philosophy of Russell that Wittgenstein always believed that Russell misunderstood the work.

The differences relate to many details, but the crucial difference is in a fundamentally different understanding of the task of philosophy. Wittgenstein believed that the task of philosophy was to clean up linguistic mistakes. Russell was ultimately concerned with establishing sound epistemological foundations. Epistemological questions such as how practical knowledge is possible did not interest Wittgenstein. Wittgenstein investigated the "limits of the world" and later on meaning. For Wittgenstein, metaphysics and ethics were nonsensical, though he did not mean to devalue their importance in life by describing them in this way. Russell, on the other hand, believed that these subjects, particularly ethics, though belonging not to philosophy nor science and of possessing an inferior epistemological foundation, were of certain interest.

Influence and decline

The immediate effect of the Tractatus was enormous, particularly by the reception it received by the Vienna Circle. However, it is now claimed by many contemporary analytic philosophers, that the Vienna Circle misunderstood certain sections of the Tractatus. The indirect effect of the method, however, was perhaps even greater long-term, especially on Logical Positivism. Like Russell, Wittgenstein eventually rejected Logical Atomism. This rejection culminated in the posthumously published book, Philosophical Investigations.
