Absurdity is a state or condition of being extremely unreasonable, meaningless or unsound in reason so as to be irrational or not taken seriously. "Absurd" is an adjective used to describe absurdity, e.g., "Tyler and the boys laughed at the absurd situation." It derives from the Latin absurdum meaning "out of tune". The Latin surdus means "deaf", implying stupidity. Absurdity is contrasted with being realistic or reasonable In general usage, absurdity may be synonymous with fanciful, foolish, bizarre, wild or nonsense. In specialized usage, absurdity is related to extremes in bad reasoning or pointlessness in reasoning; ridiculousness is related to extremes of incongruous juxtaposition, laughter, and ridicule; and nonsense is related to a lack of meaningfulness. Absurdism is a concept in philosophy related to the notion of absurdity.
History
The term absurdity has been used throughout history regarding foolishness and extremely poor reasoning to form belief.
Ancient Greece
In Aristophanes' 5th century BC comedy The Wasps, his protagonist Philocleon learned the "absurdities" of Aesop's Fables, considered to be unreasonable fantasy, and not real.
Plato often used "absurdity" to describe very poor reasoning, or the conclusion from adopting a position that is false and thus reaching a false conclusion, called an "absurdity" (argument by reductio ad absurdum). Plato describes himself as not using absurd argumentation against himself in Parmenides. In Gorgias, Plato refers to an "inevitable absurdity" as the outcome of reasoning from a false assumption.
Aristotle rectified an irrational absurdity in reasoning with empiricism using likelihood, "once the irrational has been introduced and an air of likelihood imparted to it, we must accept it in spite of the absurdity. He claimed that absurdity in reasoning being veiled by charming language in poetry, "As it is, the absurdity is veiled by the poetic charm with which the poet invests it... But in the Epic poem the absurdity passes unnoticed."
Renaissance and early modern periods
Michel de Montaigne, father of the essay and modern skepticism, argued that the process of abridgement is foolish and produces absurdity, "Every abridgement of a good book is a foolish abridgement... absurdity [is] not to be cured... satisfied with itself than any reason, can reasonably be."
Francis Bacon, an early promoter of empiricism and the scientific method, argued that absurdity is a necessary component of scientific progress, and should not always be laughed at. He continued that bold new ways of thinking and bold hypotheses often led to absurdity, "For if absurdity be the subject of laughter, doubt you but great boldness is seldom without some absurdity."
Approaches to absurdity
Rhetoric
Absurdity arises when one's own speech deviates from common sense, or when one is unable to defend oneself with speech and reason. In Aristotle's book Rhetoric, Aristotle discusses the situations in which absurdity is employed and how it affects one's use of persuasion. According to Aristotle, the idea of a man being unable to persuade someone by his words is absurd. Any unnecessary information to the case is unreasonable and makes the speech unclear. If the speech becomes too unclear; the justification for their case becomes unpersuasive, making the argument absurd.
Philosophy
Absurdity is used in existentialist and related philosophy to describe absurdly pointless efforts to try to find such meaning or purpose in an objective and uncaring world, a philosophy known as absurdism. It is illogical to seek purpose or meaning in an uncaring world without purpose or meaning, or to accumulate excessive wealth in the face of certain death.
In his paper, The Absurd, Thomas Nagel analyzed the perpetual absurdity of human life. Absurdity in life becomes apparent when we realize the fact that we take our lives seriously, while simultaneously perceiving that there is a certain arbitrarity in everything we do. He suggests never to stop searching for the absurd. Furthermore, he suggests searching for irony amongst the absurdity.
Philosophy of language
G. E. Moore, an English analytic philosopher, cited as a paradox of language such superficially absurd statements as, "I went to the pictures last Tuesday but I don't believe it". They can be true and logically consistent, and are not contradictory on further consideration of the user's linguistic intent. Wittgenstein observes that in some unusual circumstances absurdity itself disappears in such statements, as there are cases where "It is raining but I don't believe it" can make sense, i.e., what appears to be an absurdity is not nonsense.
