Antithesis

Antithesis (Greek for "setting opposite", from "against" and "placing") is used in writing or speech either as a proposition that contrasts with or reverses some previously mentioned proposition, or when two opposites are introduced together for contrasting effect. This is based on the logical phrase or term.
Antithesis can be defined as "a figure of speech involving a seeming contradiction of ideas, words, clauses, or sentences within a balanced grammatical structure. Parallelism of expression serves to emphasize opposition of ideas".
An antithesis must always contain two ideas within one statement. The ideas may not be structurally opposite, but they serve to be functionally opposite when comparing two ideas for emphasis.
According to Aristotle, the use of an antithesis makes the audience better understand the point the speaker is trying to make. Further explained, the comparison of two situations or ideas makes choosing the correct one simpler. Aristotle states that antithesis in rhetoric is similar to syllogism due to the presentation of two conclusions within a statement.
Antitheses are used to strengthen an argument by using either exact opposites or simply contrasting ideas, but can also include both. They typically make a sentence more memorable for the reader or listener through balance and emphasis of the words.
Rhetorical antithesis.
In rhetoric, antithesis is a figure of speech involving the bringing out of a contrast in the ideas by an obvious contrast in the words, clauses, or sentences, within a parallel grammatical structure.
The term "antithesis" in rhetoric goes back to the 4th century BC, for example Aristotle, "Rhetoric", 1410a, in which he gives a series of examples.
An antithesis can be a simple statement contrasting two things, using a parallel structure:
Often there is a double antithesis, as in the following proverb, where "man" is opposed to "God", and "proposes" is contrasted with "disposes":
Another type is of the form "not A, but B" (negative-positive), in which the point made is emphasised by first being contrasted with its negative:
Another type involves a antimetabole (AB, BA word order), in which the contrasted words switch places:
The negative-positive antithesis and the antimetabole-antithesis can be combined, as in the following sentence:
An antithesis can also be combined with synonymous parallelism. In the following example, the first (A, A') and second couplet (B, B') are parallel synonymously with the same adverb and verb combination distinguishing the couplets: “still do”/”still be”//”still do”/”still be.” An antithesis is formed with line A contrasting “evil” with “right” in line B. Line A' contrasts the “filthy” with the “holy” in line B'.
Some literary examples.
Some other examples of antithesis are:
The "Antitheses" in St Matthew's Gospel.
"Matthew's Antitheses" is the traditional name given to a section of the Sermon on the Mount where Jesus takes six well known prescriptions of the Mosaic Law and calls his followers to do more than the Law requires. Protestant scholars since the Reformation have generally believed that Jesus was setting his teaching over against false interpretations of the Law current at the time. "Antithesis" was the name given by Marcion of Sinope to a manifesto in which he contrasted the Old Testament with the New Testament and defined what came to be known as Marcionism.
In philosophical discussion.
In dialectics (any formal system of reasoning that arrives at the truth by the exchange of logical arguments) antithesis is the juxtaposition of contrasting ideas, usually in a balanced way. The logical arguments are said to be stated in the order thesis, antithesis, synthesis.
Although this style of philosophical discussion (stating a point of view, then its opposite, and finally drawing a conclusion) was commonly used by ancient philosophers, the use of the trio "thesis, antithesis, synthesis" itself to describe it goes back only to the 18th century, to a work published in 1794 by the German philosopher Johann Gottlieb Fichte.
The phrase is sometimes incorrectly stated to originate from the German philosopher Hegel. However, Hegel never actually used the trio of terms except once in a lecture, in which he reproached Immanuel Kant for having "everywhere posited thesis, antithesis, synthesis".
