Logical positivism
Logical positivism, formulated in the 1920s, held that only statements about facts or logical relationships between concepts make sense. These statements are not called sentences, but are said to represent true beliefs.
It should be noted, however, that although «mereological» statements may be false, logical positivists also considered them factual, so the proper name for such statements is «perception».
Logical positivists believe that while such claims are possible, they must be false anyway.
Logical positivism originated in Hegelian philosophy, especially in his dialectics and its criticism. While making some dialectical criticism of determinism, determinism itself was not part of the Marxist analysis.
The philosopher Karl Popper proposed a synthesis of logical positivism, functionalism and socialism. Popper popularized the use of the term «positivism».
Logical positivism, formulated in the 1920s, argued that the truth of a statement is «whatever is consistent with observable facts.»
The concept of a truth principle in modern logic does not imply this – for example, the statement that «all numbers are rational» is not really a statement about what is true, but only about what can be proved.
Logical positivists also do not exclude so-called non-empirical statements.
The statement that «x» or «y» is more likely to be true in the case of «X» as opposed to the case «Y» requires that «X» and «Y» be consistent statements, which they claim to be means that logical positivists must argue that «truths» of this kind are not really «truths» or «truths» of the world.
However, most subsequent systems of epistemology, such as realism, positivism, and analytical philosophy, tend to assume that logical positivists were right in saying that there are non-empirical statements that are also true.
Practical applications such as medicine and legal practice tend to focus on statements that can be falsified or supported, and thus the assertion that true statements are necessarily true is removed from the problem of determining whether a particular statement is true or false…
However, since modern theories of mind and cognition are still often based on the traditional form of empiricism, the problem of non-empirical statements is still relevant.
The statement that «x» is more likely to be true in the case of «X» than in the case of «Y» is often viewed as an example of a reduction axiom with axioms of the form «x» and «y». truth is perceived as an obvious axiom of the existence of a relationship.
However, it has also been argued that such arguments presuppose the idea that there is no cognitive system – and therefore no belief system – that can speak of something other than itself, a view that has not gained widespread acceptance.
A particularly important form of logical positivism that is commonly associated with the scientific method has come to be known as logical empiricism and is closely related to the knowledge argument for the existence of God.
In the nineteenth century, Russell, Frege and most logical positivists defended the strong version of the thesis of the logical positivists: the «logical positivism», i.e. an adequate and correct theory of knowledge itself is a true science. Since then, this thesis has been questioned by some adherents of logical empiricism.
After Wittgenstein’s theory of concepts Wittgenstein influenced the logic, some of whom believe that what is true for proposals (including the logical positivists) is true for any «concepts», and some of them believe that the truth of one kind of truth is usually and necessarily linked with truths of a different kind.
The new thesis arose as a result of the development of Wittgenstein’s philosophy. Most logical positivists denied the possibility of metaphysics; but there were some who thought that metaphysics was wrong on only one occasion, and that was when it gave meaning to things that didn’t really make sense.
Some logical positivists took this position and argued that metaphysics should only be taught in primary schools, if at all, and that metaphysics should have no place in higher education or professions. Others, however, argued that this position is inconsistent.
Russell called the first position «twice negative logic.»
In the second position, «double positive logic» describes the usual human use of language in which there is no opposition between sentences that imply or make sense of each other.
When Wittgenstein and his followers speak of an «intentional binding relationship,» they mean that the word must refer to something else in order to have meaning.
From this point of view, there is no metaphysics or even the science of metaphysics, because there is no opposite entity in the universe.
Many of the conclusions Wittgenstein is t e, which are known as anti comprehensionist, in fact, they argue that any relation between the world and the human mind, there must be.
In his Remarks on Foundations of Mathematics, Wittgenstein argued that (at least briefly and in extremely restrictive terms) there is no truth, reality or existence as we know them.
In his Treatise on Human Knowledge, and in his treatise on logic and philosophy, Wittgenstein believed that an attempt to explain the world of formal logic was likely to give a false idea of reality. Logical positivists were in principle open to these objections.
Wittgenstein later argued that the rejection of transcendental idealism (and therefore ontology) was a major mistake of logical positivists, because it led them to misunderstand the nature of objects. He called their position «superstitious» because it is based on the false belief that one can distinguish «what is real» from «what is false», which he himself considered dubious.
According to Wittgenstein, it is obvious to logical positivists that nothing real can matter and that everything that is either a phenomenon or an illusion (or something that can be called a phenomenon or an illusion). He called the approach of the logical positivists «superstitious» because it is based on the assumption that they can only explain the world «by the terms on which we are allowed to speak of what is real,» and that they did not realize that reality cannot be treated in this way.
As Wittgenstein argued, and as Fodor and Eilanden argued for his arguments, it is impossible to speak of «the world» using the terms adopted by logical positivists, and it is meaningless to say that it is possible to describe the world with the conditions they use.
Wittgenstein’s arguments show that it is impossible to explain the world in the language of logic (or his paradigm of language, Tractatus Logico – Philosophicus).
One of the results is that Wittgenstein believed that a person cannot even speak about what is real using the language of logic, since logic cannot identify what is real. He also argued that it is impossible to identify «that which is possible» with the terms in which they speak about him (and, in the same way, it is impossible to identify «that which is unreal» with the terms in which they speak about him).
According to Wittgenstein, both «unreal» and «impossible» can be defined based on the terms used to describe them.
It is important to note that all this talk about the language used to describe reality and the language used to identify things that cannot be spoken to are entirely conceptual. It is not at all obvious that language in general, or logic of statements in particular, can be used to describe reality or what is «impossible».
Logical positivists took Wittgenstein ’s arguments about what they were, about the impossibility of describing the world in language, as about the meaninglessness of statements. And in later life, Wittgenstein seems to have adopted the positivist assumption that language does not matter and cannot distinguish the unreal from the real.
However, this «logical positivism» is actually much more concrete than
