What Is a Paradox? Definition & 10+ Examples

Ever stumbled upon a statement that defies logic, yet somehow makes sense? If this resonates with you, then you have encountered a paradox.

A paradox often challenges one’s understanding of logic and reasoning. At its core, a paradox is a statement or scenario that contradicts itself or presents a seemingly impossible situation. These paradoxes come in different forms, from self-referential statements to contradictory scenarios, and they often pose challenges that push the boundaries of conventional wisdom.

In this article, we will explore these seemingly illogical phenomena that continue to captivate our interest and challenge our critical thinking. We will also present an array of paradoxes, illustrating their diverse nature and the intriguing implications they hold.

By investigating various paradoxes and their implications, one can gain a deeper understanding of logic, language, and human thought processes. Understanding paradoxes is not just a mental exercise; it’s an investigation that pushes us to reassess our beliefs and question the foundations of our knowledge.

Let’s get started:

What Is a Paradox?

A paradox is a noun that represents a statement or phenomenon that appears contradictory or self-defeating yet may still be true or make sense in some contexts.

The dictionary defines a paradox as “a statement or proposition that, despite sound (or apparently sound) reasoning from acceptable premises, leads to a conclusion that seems senseless, logically unacceptable, or self-contradictory.”

The word paradox has its roots in two ancient languages: Latin and Greek. The Latin term paradoxum is derived from the Greek word parádoxon, which is a combination of two words – para-, meaning “contrary to,” and doxa, meaning “opinion” or “belief.”

In the realm of logic and philosophy, paradoxes serve as catalysts for deepening understanding and questioning established frameworks. They can be found in various disciplines such as mathematics, literature, and even everyday language, prompting intellectual curiosity and exploration.

Various types of paradoxes exist, including:

  • Logical paradoxes: These involve contradictory elements that arise from an inconsistency in the rules of logic. An example is Russell’s Paradox derived from set theory.
  • Semantic paradoxes: These arise from linguistic inconsistencies and involve self-reference or circularity of meaning. The Liar Paradox is a classic example of this type.
  • Empirical paradoxes: These occur when observations defy expectations or established theories. The Simpson’s Paradox in statistics is one such empirical paradox.

In summary, a paradox is a seemingly contradictory statement or phenomenon that stems from language variations and inconsistencies in logic, often challenging and expanding existing knowledge. The term’s origin in Latin and Greek highlights its long-standing presence and influence in various fields of thought.

Types of Paradoxes

Logical Paradox

A logical paradox is a self-contradictory statement that arises from seemingly valid reasoning. These often challenge our understanding of logic and highlight inconsistencies within a system. Examples include:

  • The liar paradox: “This sentence is false.” If the statement is true, then it’s false, but if it’s false, then it’s true.
  • Russell’s paradox: Consider a set containing all sets that don’t contain themselves. Does this set belong to itself? If it does, it shouldn’t, and if it doesn’t, it should.

Logical paradoxes can be divided into several subcategories:

Veridical Paradoxes

These paradoxes seemingly contain a contradiction but actually reveal a surprising truth.

Example: The Birthday paradox states that the chance of at least two people sharing a birthday in a group of 23 is over 50%, which seems counterintuitive but is statistically accurate.

Falsidical Paradoxes

These involve an apparent contradiction arising from false premises, such as the barber paradox: A barber shaves all and only those men who don’t shave themselves. Who shaves the barber? This paradox carries a hidden assumption that the barber must exist, which is ultimately flawed.


Antinomies are paradoxes arising in philosophy and logic when two seemingly valid principles contradict each other. They present situations where determining the truth between opposing principles is challenging, as both appear well-grounded.

Antinomies highlight inconsistencies or limitations within philosophical or logical systems, prompting further examination and refinement. Immanuel Kant, a German philosopher, famously discussed four antinomies in his work Critique of Pure Reason. These involve fundamental questions about space, time, causality, the universe, and freedom versus determinism.

Kant argued that antinomies arise due to limitations in human understanding when applying pure reason to metaphysical questions. As a result, antinomies serve as a reminder of the complexities and boundaries of human knowledge.

Literary Paradox

In literature, paradoxes are used as a rhetorical device, often to emphasize the complexity of a situation or provide insight into characters and themes. Examples include:


An oxymoron is a figure of speech that combines contradictory terms, such as “deafening silence” or “bittersweet.” These can be used for dramatic effect, highlighting the tension or contradictions in a particular situation.

Situational Paradoxes

These occur when actions or events lead to unexpected results or highlight the absurdity of a situation.

Example: In George Orwell’s 1984, the slogan “War is Peace, Freedom is Slavery, Ignorance is Strength” is an example of the situational paradoxes often found in dystopian literature.

Gender Paradox

The gender paradox describes situations in which societal expectations about gender roles and behaviors lead to contradictions or conflicting outcomes. Examples include:

  • The Double Bind: Women who are ambitious and assertive are often labeled as “bossy” or “unfeminine,” while women who are more passive or accommodating may not advance in their careers, thus facing a lose-lose situation.
  • The Male Gender Paradox: Men are often socialized to be strong and unemotional, but this expectation can lead to isolation, mental health issues, and difficulty forming deep relationships.

These paradoxes highlight the inconsistencies and limitations of certain gender norms, and they challenge readers or listeners to rethink their assumptions about gender roles and expectations.

Did You Know? The Unexpected Hanging Paradox consists of a prisoner sentenced to an unexpected hanging, struggling to determine which day executions might take place during the week. The paradox demonstrates how knowledge about certain constraints can lead to seemingly contradictory conclusions.

Paradox in Literature

William Shakespeare

Paradoxes are prevalent in many of Shakespeare’s works, showcasing his mastery of language and rhetoric.

  • In Hamlet, the famous “to be or not to be” soliloquy exemplifies a paradox as Hamlet wrestles with the idea of existence and its opposite.
  • In Romeo and Juliet, the phrase “feather of lead” is used to describe the feeling of love — simultaneously delicate and heavy.

George Orwell

George Orwell’s Animal Farm is rich with paradoxical statements and thoughts, often serving as a means to illustrate the corruption and manipulation within the farm’s society.

One notable example is the phrase, All animals are equal, but some animals are more equal than others.” This paradoxical statement critiques the hypocrisy within the ruling class, highlighting the issues of inequality and injustice.

Joseph Heller

In Joseph Heller’s Catch-22, paradox takes center stage as the story’s central theme. The titular catch refers to a fictional rule stating that a soldier can be deemed insane for wanting to continue flying dangerous missions, but to request relief from duty due to insanity displays rationality, rendering the soldier sane and forced to continue flying.

This paradox effectively traps the protagonist and other soldiers in a never-ending cycle of dangerous and absurd situations.

Famous Paradoxical Quotes


Socrates, the renowned Greek philosopher, was known for his thought-provoking paradoxical quotes. One of his most famous paradoxes is the Socratic Paradox, which states:

"I know that I am intelligent, because I know that I know nothing."

This quote highlights the idea that true wisdom stems from recognizing one’s own ignorance.

Oscar Wilde

Oscar Wilde, the Irish poet, and playwright, was famous for his wit and clever use of paradox in his work. Some notable quotes from him include:

  • “I can resist everything except temptation.”
  • “The only way to get rid of a temptation is to yield to it.”
  • “To be natural is such a very difficult pose to keep up.”

These quotes showcase Wilde’s ability to turn conventional thinking on its head through the use of paradox.

George Bernard Shaw

George Bernard Shaw, the Irish playwright, and social critic, also made use of paradox in his work. A few examples of his paradoxical quotes are:

  • “The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.”
  • “Those who cannot change their minds cannot change anything.”
  • “The only man who behaves sensibly is my tailor; he takes my measure anew each time he sees me, while all the rest go on with their old measurements and expect them to fit me.”

Shaw’s paradoxical statements often challenge the status quo and encourage readers to question societal norms.

Famous Examples of Paradox

Classical Examples

The classical examples of paradoxes have their roots in ancient philosophy and mathematics. Some well-known classical paradoxes are:

Zeno’s Paradoxes

A set of paradoxes developed by the Greek philosopher Zeno of Elea, which highlight the concept of infinity and its implications.

One famous example is Achilles and the Tortoise, in which Achilles can never catch up to a tortoise, given a small head-start, due to the infinite division of the remaining space.

The Liar Paradox

This paradox revolves around the statement, “This sentence is false”. If it is true, then it means the sentence is false, but if it is false, then it means the sentence is true. This creates a logical inconsistency.

The Barber Paradox

Proposed by the British philosopher Bertrand Russell, this paradox is about a barber who shaves all those who do not shave themselves. However, if the barber shaves himself, he would no longer be shaving those who do not shave themselves, creating a paradox.

Modern Examples

Modern paradoxes often stem from scientific and technological advancements. Some examples include:

The Grandfather Paradox

This paradox is related to the concept of time travel. If a person travels back in time and kills their grandfather before their parent is born, it would mean the time traveler would never have existed, resulting in a logical contradiction.

Schrödinger’s Cat

This paradox, introduced by Austrian physicist Erwin Schrödinger, involves a thought experiment in which a cat is placed in a sealed box with a radioactive atom, a Geiger counter, and a vial of poison.

If the Geiger counter detects radiation, the vial is broken, and the cat dies. According to quantum mechanics, the cat is simultaneously alive and dead until the box is opened and observed.

The Monty Hall Problem

This statistical paradox involves a game show scenario where a contestant is asked to choose one of three doors, behind one of which is a valuable prize, and behind the others, goats.

After the initial choice, the host, Monty Hall, reveals a goat behind one of the other doors and offers the contestant the chance to switch their choice. Statistically, it is more advantageous for the contestant to switch, which is counterintuitive for many.

Paradoxes in Film and Media

Paradoxes have long been a captivating element in film and media, as they offer a unique way to challenge viewers’ perceptions and create intriguing narratives.

Bootstrap Paradox in Back to the Future (1985) Film

One famous example of a paradox in film is the bootstrap paradox found in time travel movies. This paradox occurs when an object or piece of information is sent back in time, creating a cause-and-effect loop without a clear origin. This paradox raises questions about self-causality and the nature of time.

A well-known illustration of this phenomenon is the movie Back to the Future (1985), in which Marty McFly’s actions in the past influence his present life.

Identity Paradox in the Moon (2009) Film

In science fiction films, paradoxes often emerge from the interplay between reality and virtual environments. For instance, the Moon film delves into the realm of human cloning and the resulting ethical dilemmas.

In this movie, a lonely astronaut named Sam discovers that he is not the original version of himself but a clone created to replace his predecessor. This revelation brings forth a paradoxical question: is Sam’s identity real or fabricated?

The film explores the implications of artificial existence and the concept of self in a thought-provoking manner.

Reality Paradox in Inception (2010) Film

Movies also use paradoxes to stimulate philosophical discussions. For example, the film Inception introduces the idea of dreams within dreams, creating layers of reality that become increasingly difficult to distinguish from one another.

As the characters navigate through these intertwined realities, viewers are encouraged to ponder the nature of our own existence and question the boundaries between the real and the imagined.

Paradoxes in film and media often provoke deep philosophical questions and stimulate rich conversations about reality, existence, and the nature of humanity. They serve as a thought-provoking device that enhances storytelling and ensures that audiences engage with the material on a deeper level.

Fun Fact: The Paradox of Tolerance, formulated by philosopher Karl Popper, states that unlimited tolerance toward intolerant beliefs results in the disappearance of tolerance itself.

Paradox in Poetry and Lyrics

Paradox is a rhetorical device that poets and lyricists often use to create a sense of intrigue and explore complex ideas.


In poetry, a paradox can bring attention to contradictory elements that coexist within a single concept, thereby helping the reader to question conventional wisdom and explore a deeper meaning.


In the realm of lyrics, a paradox is used to illustrate the complexities of human emotions and relationships.

For example, it can be found in songs where the lyrics express the desire to hold on to love while simultaneously wanting to let go. This juxtaposition of contrasting feelings helps to convey the internal struggle experienced by many people in their personal lives.


A classic example of paradox in literature can be found in Oscar Wilde’s play The Importance of Being Earnest. The title itself presents a paradox: is it essential to be earnest, or is the author suggesting that life is more enjoyable when people are not entirely serious? As it turns out, the play explores the tension between social propriety and the pursuit of personal happiness.

Some common examples of paradox in poetry and lyrics are:

  • “To be or not to be” from Shakespeare’s Hamlet.
  • “Less is more” in Robert Browning’s poem Andrea del Sarto.
  • “The child is father of the man” from William Wordsworth’s My Heart Leaps Up.

The Power of Paradox: Challenging Conventional Thought

When used effectively, paradox can offer a thought-provoking lens through which readers can engage with complex and contradictory ideas.

The power of paradox lies in its ability to challenge readers to question the world around them, prompting reflection and fostering a deeper understanding of human nature.

Paradoxical Themes and Motifs

Love and Expectation

Paradoxical themes in literature often revolve around love and expectation. Love, in its various forms, can be conflicting and contradictory. Expectations placed upon individuals by societal norms or personal desires can create a sense of confusion. Examples include the following:

  • One might love someone deeply yet feel frustrated by their actions or choices. This conflicting state creates a paradox that only deepens as emotions intensify.
  • An individual may struggle to meet expectations, trying to satisfy both themselves and others while never fully achieving either goal.

Truth and Reason

Truth and reason are essential concepts in paradoxical literature. Often, characters face a dilemma that presents a choice between revealing the truth and preserving rationality. This strain tests the limits of the individual’s moral compass, as well as the audience’s.

One classic example is Claudius in Shakespeare’s Hamlet. He grapples with the truth of his actions concerning his brother, trying to conceal them behind a veneer of reason. The paradox here lies in attempting to uphold rationality while simultaneously suppressing an undeniable reality.

Absurdity and Frustration

Absurdity and frustration are common themes in paradoxical literature, representing situations where logical reasoning fails to provide clarity. Characters often face obstacles or experiences that challenge their sense of rationality, leaving them feeling frustrated and overwhelmed.

For instance, a character may face an absurd predicament that leaves them doubting their sanity, unable to reconcile their perceptions with any apparent logic.

This frustration can manifest itself in various ways, such as feelings of anger, bitterness, or disillusionment. The entanglement of absurdity and frustration highlights the limitations of human reasoning and its capacity to make sense of the world.

These themes allow authors to explore intricate layers of emotion and thought while challenging readers to engage with multi-faceted aspects of the human condition.

Role of Paradox in Language


Paradox often plays a role in humor as it can create situations where two opposing ideas or contradictory statements are presented, generating amusement.

Examples of humorous paradoxes can be found in jokes, puns, and witty remarks, where the unexpected or ironic twist leads to laughter. In some cases, the apparent absurdity of a paradox can provide comic relief or make light of serious subjects.


In speech, paradox can serve various purposes, such as:

  • Emphasizing a certain point.
  • Expressing complex thoughts more effectively.

By presenting contradictory statements, paradoxes grab the listener’s attention and encourage further reflection on the subject. This rhetorical device can be used to support arguments, provoke discussion, or create memorable phrases that resonate with the audience.

Figure of Speech

Paradox is also an important figure of speech in language and literature, as it can convey deeper meaning, stimulate the reader’s imagination, and create memorable expressions.

Common examples of paradoxical figures of speech include:

  • Oxymorons (e.g., “deafening silence”)
  • Litotes (e.g., “not an easy task”)
  • Antithesis (e.g., “to err is human, to forgive, divine”)

These devices work by juxtaposing contrasting ideas, showcasing the richness and subtlety of language.

Significance and Impact of a Paradox

Paradoxes hold a considerable value in challenging our understanding of concepts and stimulating critical thinking. They often present themselves as statements or propositions that are in opposition to prevailing beliefs, causing astonishment and unexpected outcomes.

The importance of paradoxes can be seen in various intellectual disciplines, such as philosophy, mathematics, and science, where they serve as tools to analyze our assumptions and reveal inconsistencies within systems of thought.

By addressing the antithesis within paradoxes, scholars can work towards new discoveries and refine existing models or frameworks that are central to their fields of study.

In the modern world, paradoxes have also found their applications in the development of innovative technologies and solutions. Some examples of paradoxes that play a significant role in modern advancements include:

  • Russell’s Paradox in set theory, which has led to the development of alternative logical frameworks and the foundation of computer science.
  • The EPR Paradox in quantum physics, which questions the nature of reality and has significant implications for quantum computing and encryption technologies.
  • The Arrow’s Impossibility Theorem in economics, which highlights the challenges in designing a democratic system that maximizes fairness and social welfare.

By identifying and addressing these paradoxes, researchers and practitioners can work towards enhancing their understanding of the systems they study, ultimately leading to positive advancements and improvements within their respective fields.

How to Identify Paradoxes

  1. Identify the statement or concept being presented.
  2. Analyze the logic and reasoning behind it.
  3. Determine if the statement appears self-contradictory, absurd, or contradictory to common sense.
  4. Examine the situation or context in which it arises.
  5. Evaluate the validity of the paradox as either veridical, falsidical, or an antinomy.

Understanding and recognizing paradoxes can sharpen critical thinking skills and provide valuable insight into the complexities of language, logic, and human thought.

Pros and Cons of Using a Paradox

A paradox can be a powerful tool in various forms of communication, including literature, philosophy, and everyday conversation. However, it also comes with its own set of advantages and disadvantages.


  • Engagement: Paradoxes encourage critical thinking and provoke curiosity. They stimulate the mind and invite readers or listeners to engage with complex ideas.
  • Memorability: Their contradictory nature captures attention, making them more memorable and effective at conveying a message.
