Nihilism is a family of views that reject or deny certain aspects of existence.^[2] Different forms of nihilism deny different features of reality. For example, existential nihilism denies that life has a higher meaning, and moral nihilism rejects the existence of moral phenomena. Similarly, epistemological nihilism questions the possibility of objective knowledge, while political nihilism advocates the destruction of established political institutions.^[1] The precise definition of nihilism is disputed, and many other definitions and types of nihilism have been proposed, covering a wide range of topics studied by different branches of philosophy, such as ethics, value theory, epistemology, and metaphysics.^[3]

In addition to philosophical theories, nihilism can also refer to a broader cultural phenomenon or historical movement. In this context, it is primarily associated with modernity in the Western world, characterized by deep skepticism toward established norms and values alongside indifference, despair, and a lack of purpose.^[4] Outside the academic discourse, the term nihilism is used more loosely in everyday language to describe negative, destructive, or antisocial attitudes, expressing that someone fails to care about a particular issue. For instance, conservatives may be labeled as nihilistic for not valuing progress, while progressives may be described as such for disregarding established norms.^[5]

Nihilism is closely associated with other disillusioned attitudes toward the world, like pessimism, absurdism, existentialism, cynicism, and apathy. Although the meanings of these terms overlap, they have distinct connotations and do not necessarily imply one another.^[7] Pessimism contrasts with optimism as a negative outlook focused on bad outcomes and characterized by hopelessness. A key difference to nihilism, according to one interpretation, is that pessimists see the world as inherently bad, whereas nihilists deny that it has any positive or negative meaning.^[8] Absurdism argues that the world is not just meaningless, as existential nihilism asserts, but also absurd. It examines the absurdity arising from paradoxical attempts to find meaning in an inherently meaningless universe.^[9] Existentialism is a philosophical tradition that addresses absurdist and nihilist views while exploring the human condition through themes like anxiety, death, freedom, and authenticity.^[10] Cynicism is a distrustful attitude toward the motives of other people or society in general.^[11] Apathy is a state of mind in which a person does not care about things, characterized by indifference and a lack of desires and emotions.^[12]

The word nihilism is a combination of the Latin term nihil, meaning 'nothing', and the suffix -ism, indicating an ideology. Its literal meaning is 'ideology of nothing' or 'ideology of negation', reflected in terms like annihilate and nihility.^[13] The word emerged in 18th-century Germany, first as a literary term and later as a philosophical notion, which Friedrich Heinrich Jacobi conceptualized to criticize philosophical thought that rejects meaning or existence.^[14] Its first recorded use in English dates to the 1810s.^[15] The term became popular in 19th-century Russia through Ivan Turgenev's novel Fathers and Sons and the Russian nihilist movement. Interest in it increased more broadly in the 20th century in response to Friedrich Nietzsche's works, while its meaning expanded to cover a wider range of philosophical and cultural phenomena.^[16]

Forms of nihilism belonging to the fields of ethics and value theory question the existence of values, morality, and the meaning of life.^[18]

Existential nihilism asserts that life is meaningless. It is not limited to the idea that some people fail to find meaning in their lives but makes the broader claim that human existence in general or the world as a whole lacks a higher purpose. This view suggests that living a genuinely meaningful life is impossible, that there is no higher reason to continue living, and that all efforts, achievements, happiness, and suffering are ultimately pointless.^[19]

Existential nihilism has diverse practical implications since people usually act with a purpose in mind, sometimes with the explicit goal of making their lives meaningful. As a result, the belief that there is no higher meaning or purpose can bring about indifference, a lack of motivation, and anxiety. In extreme cases, this can result in depression and despair or trigger an existential crisis.^[20][b] Some philosophers, such as Martin Heidegger, highlight the connection to boredom, arguing that the lack of engagement and goals experienced in this mood makes life appear pointless.^[22]

Diverse possible reactions to existential nihilism have been proposed.^[24] Inspired by Indian philosophy, Arthur Schopenhauer suggested a pessimistic and ascetic response, advocating detachment from the world by renouncing desires and stopping to affirm life.^[25] Friedrich Nietzsche sought to use the disruptive force of nihilism to re-interpret or re-evaluate all established ideals and values in an attempt to overcome nihilism and replace it with an affirmative attitude toward life.^[26][c] Jean-Paul Sartre suggested that people can create their own values through the free choices they make, despite the cosmic lack of meaning. After considering the possibility of committing suicide, Albert Camus argued instead for a defiant attitude in which individuals rebel against meaninglessness.^[28] Other responses include a destructive attitude aiming to violently tear down political authorities and social institutions, attempts to undermine nihilism by identifying genuine sources of meaning, and a passive resignation or quiet acceptance.^[29]

Arguments for and against existential nihilism are discussed in the academic discourse. Arguments from a cosmological perspective assert that human existence is a minor and insignificant aspect of the universe as a whole, which is indifferent to human concerns and aspirations. This outlook aligns with an atheistic view, stating that, without a God, there is no source of higher values that transcend the natural world. Another viewpoint highlights the pervasiveness of senseless suffering and violence while emphasizing the fleeting nature of happiness. Some theorists link this view to human mortality, suggesting that the inevitability of death renders all human accomplishments transient and ultimately futile.^[30] A different perspective from biology argues that life is driven by blind natural selection on a large scale and the satisfaction of innate needs on an individual scale, neither of which aims at a higher purpose.^[31] Subjectivists, by contrast, focus on the subjective nature of all value experiences, asserting that they lack any objective ground.^[32]

Opponents of existential nihilism have responded with counterarguments to these statements. For example, some reject the pessimistic outlook that life is primarily characterized by suffering, violence, and death, claiming instead that these negative phenomena are counterbalanced by positive experiences such as happiness and love.^[33] Many non-nihilistic theories of the meaning of life are examined in the academic discourse. Supernaturalistic views focus on God or the soul as sources of meaning. Naturalistic views, by contrast, assert that subjective or objective values are inherent in the physical world. They include the discussion of fields where humans actively find meaning, such as exercising freedom, committing oneself to a cause, pursuing altruism, and engaging in positive social relationships.^[34]

Unlike existential nihilism, moral nihilism focuses specifically on moral phenomena rather than a higher meaning or purpose. In its broadest form, it is the metaethical view that there are no moral facts. Also called amoralism and error theory, it denies the objective existence of morality, arguing that the theories and practices categorized under this label rest on misguided assumptions without any substantial link to reality.^[35] On a practical level, some moral nihilists, such as Nietzsche, assert that without moral obligations, anything is permitted, suggesting that people are allowed to act however they want. Other moral nihilists reject this conclusion and argue that the denial of morality affects not only moral obligations, or what people are required to do, but also moral permissions, or what people are allowed to do.^[36] Axiological nihilism, a related view, disputes the objective existence of values in general. This rejection is not limited to moral values and also concerns other types, like aesthetic and religious values.^[37]

One argument for moral nihilism suggests that moral properties do not exist because of their odd nature, prescribing what to do rather than describing facts, such as shape and size. Science-based versions of this view hold that scientific inquiry does not reveal objective moral facts or that humans lack a source of moral knowledge. A related argument for moral nihilism focuses on the conventional aspects of moral evaluations and the difficulties in resolving moral disagreements.^[38] Another line of thought emphasizes the evolutionary origin of morality, viewing it as a mere product of natural selection without a deeper metaphysical foundation.^[39]

Moral realists have raised objections to moral nihilism. Naturalists argue that moral facts belong to the natural world and can be empirically observed. Non-naturalists propose that moral phenomena are different from natural phenomena, but are real nonetheless.^[40] Common-sense philosophers assert that moral beliefs are deeply ingrained in practical experience and everyday reasoning, making the wholesale denial of moral facts implausible. A similar objection asserts that moral nihilism is incoherent and rests on a misunderstanding of moral language. Some critics focus on negative practical consequences rather than truth, suggesting that moral nihilism erodes social trust and leads to antisocial conduct.^[41]

Some philosophers use the term moral nihilism in a more restricted sense that does not imply a rejection of all forms of morality. In one alternative sense, moral nihilism is the same as moral subjectivism, arguing that moral evaluations are purely subjective and lack rational objective justification. As a result, moral judgments are seen as expressions of arbitrary personal preferences, making moral disagreements rationally unresolvable.^[42] In another sense, moral nihilism refers to ethical egoism, the theory that morality is determined by self-interest. This view denies that the well-being of others has moral implications unless it has external consequences for one's own well-being.^[43]

Epistemological or epistemic nihilism is a family of views that challenge the existence or universal nature of knowledge. Some versions embrace relativism, denying that objectivity is possible. For example, truth-relativism asserts that truth is relative to the perspectives of specific individuals, groups, historical epochs, or cultural contexts.^[d] According to this view, statements like "the sun rises in the east" and "killing is wrong" are true in some perspectives and false in others. This theory not only claims that different people have different opinions but additionally asserts that no independent framework exists to assess which opinion is ultimately correct. As a result, there is no absolute truth on which observers from different perspectives can agree.^[45]

A related form of relativistic nihilism focuses on meaning rather than truth. It argues that different people rely on incompatible conceptual schemes^[e] to make sense of the world. In the absence of a universal framework, genuine communication and shared understanding are deemed impossible since each viewpoint has its own interpretation of reality. Without a common ground, these incommensurable belief systems are arbitrary constructions, limiting reason to operations within a specific system without the ability to reconcile them.^[47]

Proponents of relativism emphasize the diversity of human viewpoints and the frequent inability to resolve disagreements and reach a shared understanding.^[49] Another argument asserts that theories are usually underdetermined by the data supporting them. As a result, there are different equally valid interpretations without an objective standard to resolve their differences.^[50] An influential criticism argues that relativism undermines itself: if all truths are relative to a viewpoint, then relativism itself is only true for some viewpoints and false for others.^[51] Another objection is that the absence of absolute epistemic standards may have odd consequences, for example, that people should not argue if they disagree or that they should generally suspend their judgments.^[52]

Nietzsche was an influential proponent of relativistic nihilism. He saw belief systems as an expression of the will to power, arguing that their goal is to assert dominance rather than represent reality.^[53] In postmodern philosophy, epistemological nihilism is associated with antifoundationalism, arguing that there is no ultimate rational ground of knowledge or action. It challenges universal frameworks, termed grand metanarratives, that claim to provide such a ground.^[54]

While relativist versions of epistemological nihilism allow that knowledge exists relative to a perspective, skeptic versions deny the existence of knowledge in general.^[f] Also called radical skepticism, this view argues that there is no foundation or justification of knowledge claims. Unlike more moderate forms of skepticism, it questions even the most reasonable knowledge claims grounded in basic common sense.^[56] A closely related form of epistemological nihilism, sometimes called alethiological nihilism, centers on truth rather than knowledge, stating that truth does not exist.^[57]

One argument in favor of radical skepticism asserts that absolute certainty is required for knowledge. It attempts to show that doubt can never be fully expelled.^[58] For example, the dream argument, suggested by philosophers such as René Descartes, points out that, while dreaming, people usually cannot distinguish between dream and reality. Based on this observation, it argues that there is no knowledge since an individual can never be certain that they are not currently dreaming.^[59] A related approach, inspired by Roderick Chisholm, asserts that a criterion or a standard of evaluation is required to judge what counts as knowledge. It holds that knowledge is impossible because people cannot have this criterion without prior knowledge, meaning that knowledge and its criterion cannot be established independently, as each relies on the other, similar to the chicken-or-the-egg problem.^[60][g] Despite these arguments, radical skepticism is a rare position, accepted only by few philosophers and challenged by many criticisms. Its main influence stems from attempts by non-skeptical philosophers to prove that their theories overcome the challenge of skepticism.^[62] Some objections state that radical skepticism is incoherent or self-refuting. For example, if there is no knowledge then skeptics cannot know that there is no knowledge, making it questionable why anyone should believe their theories.^[63] Another counterargument is that common sense gives stronger support for the existence of knowledge than the abstract arguments used to defend skepticism.^[64]

Epistemological nihilism can lead to other forms of nihilism. For instance, the inability to discern the meaning of life can lead to the conclusion that there is no such meaning, resulting in existential nihilism.^[65] Moral skepticism, the view that there is no moral knowledge, can have a similar effect: the incapacity to distinguish right from wrong behavior can lead to the rejection of moral facts. Some theorists associate epistemological nihilism primarily with moral skepticism.^[66]

Metaphysical or ontological nihilism encompasses views about the fundamental nature of reality. One version addresses the question of why there is anything at all. It suggests that, at least in principle, an empty world is possible. While this view recognises that the world contains concrete objects, it argues that their existence is not inevitable, because there could have been nothing. In such a scenario, the universe would be entirely empty, without any people, animals, planets, and no other forms of matter or energy.^[67]

The subtraction argument proposes a procedure to support this view. It states that the world does not depend on any particular concrete object. For example, the world could still exist if a specific rock was removed. The argument concludes that an empty world is possible since it is the result of continuously reapplying this idea, subtracting objects at each step until an empty universe remains.^[68][h] Opponents of metaphysical nihilism assert that an empty world is impossible, meaning that something must exist. A theologically inspired version asserts that God is a necessary object that must be present even if nothing else is. Another version accepts that any individual concrete object can be removed, but not all at once. It asserts that abstract objects, such as natural numbers, have necessary existence and that they require the existence of at least some concrete objects without depending on any specific object in particular.^[70]

A more radical and controversial form of metaphysical nihilism denies the actual existence of objects. It states that there is no world, arguing that the experience of the universe is a mere illusion without an underlying reality. As a result, nothing at all is real. This view is sometimes interpreted as a form of solipsism, proposing that only the self exists and that the external world is merely an idea held by the self without a substantial reality.^[71]

Mereological or compositional nihilism is the view that complex or composite objects do not exist. Composite objects are objects made up of proper parts. For example, a house is a composite object made up of parts like walls, windows, and doors. Each of these parts is itself a composite object made up of smaller parts, such as molecules and atoms. Mereological nihilists argue that only noncomposite or simple objects exist, such as elementary particles. As a result, composite objects are understood as mere collections of simple objects. According to this view, there are no houses or tables; there are only elementary particles arranged house-wise or table-wise.^[72]

Proponents of mereological nihilism highlight the parsimony and simplicity of a minimal ontology that excludes everything except simple objects, citing metaphysical principles like Ockham's Razor in its favor.^[73] Another supporting argument suggests that mereological nihilism avoids certain metaphysical paradoxes associated with the relation between parts and wholes, like the Ship of Theseus.^[74][i] Opponents of mereological nihilism highlight the counterintuitive consequences of denying the existence of ordinary objects, contradicting common sense.^[76] Other criticisms assert that mereological nihilism is unable to provide a coherent framework for how to understand collections of elementary particles or fails to explain phenomena like emergent properties.^[77]

Cosmic or cosmological nihilism is the view that reality is unintelligible and lacks inherent meaning. Closely related to epistemological and existential nihilism, it asserts that the world is blank, featureless, or chaotic, making it indifferent to human attempts to understand it. Cosmic nihilists often emphasize the vastness of the universe, arguing that it shows the insignificance of humans and their endeavors.^[78]

A broad form of cosmic nihilism states that reality as a whole is unintelligible. According to this view, the chaotic nature of the world makes it impossible to comprehend the universe at any level or find meaningful patterns in it, leading to alienation as human understanding fails to grasp reality.^[79] For example, Max Stirner characterized the world as a "metaphysical chaos" without "a comprehensive structure of objective meanings".^[80] In response to arguments stating that it is possible in certain cases to discern patterns and predict outcomes, some cosmic nihilists have proposed more narrow versions. One version acknowledges that humans can understand some aspects of reality, for example, through rigorous scientific study. Nonetheless, this view maintains that the universe remains impenetrable to comprehension and indifferent to human aspirations on other levels, lacking intelligible structures that correspond to objective values, moral principles, and a higher purpose.^[79]

In addition to the main nihilistic theories discussed in ethics, value theory, epistemology, and metaphysics, nihilism is also examined in other areas. Discussions include fields such as literature, art, culture, and politics.^[83] Various literary works portray characters or attitudes that reject established norms, exhibit disillusionment with life, or struggle with existential despair. Bazarov, the protagonist of Ivan Turgenev's novel Fathers and Sons, is an early and influential example. Driven by a deep distrust of established authorities, Bazarov follows a cold scientific rationalism. He openly expresses his hate toward conventional beliefs, societal norms, and sentimentality, aiming to dismantle them without a vision of what should replace them.^[84] In response to Turgenev's novel, Nikolay Chernyshevsky's What Is to Be Done? explored nihilism from the perspective of rational egoism.^[85] Many of Fyodor Dostoevsky's works explore the problem of nihilism, particularly the idea that without God, there is no moral basis for right or wrong.^[86] For example, his novel The Brothers Karamazov examines the tensions between faith, free will, and nihilism through the perspectives of the protagonists.^[87] Nothingness is a central concern for many characters in the works of Samuel Beckett, either as the object of desire or fear.^[88] Nihilist themes are also present in the literary works of Franz Kafka, Jean-Paul Sartre, and Albert Camus.^[89]

In the field of art, Dadaism emerged during the First World War as a nihilistic rejection of established moral, societal, and artistic standards. Dadaists embraced chaos, spontaneity, and irrationality, infusing their art with irreverence, nonsense, and humor to provoke and challenge traditional conceptions of art. For example, Marcel Duchamp presented Fountain, a readymade urinal, at an art exhibition, which became one of the most iconic pieces of the movement.^[81] In cinema, the movie Citizen Kane suggests a form of epistemic nihilism, showcasing moral ambiguity and the impossibility of arriving at an objective assessment of the protagonist's character.^[90] Elements of nihilism are also found in movies such as Taxi Driver,^[91] A Clockwork Orange,^[92] Fight Club,^[93] The Big Lebowski,^[94] and American Psycho.^[95]

In the field of law, legal nihilists assert that laws lack an inherent meaning or a moral foundation, viewing them as unjust or arbitrary constructs used to maintain control and exercise power.^[96] Religious or theological nihilism is associated with atheism and denies the existence of God. Some theorists identify this view as the root of other nihilist outlooks, such as existential and moral nihilism.^[97]

In the philosophy of language, semantic nihilism denies that linguistic meaning is possible, arguing that there is no genuine communication since language fails to describe reality.^[98] Logical nihilism is a theory about the relation between formal logic and natural language inference. It asserts that the logical consequence relation studied by logicians is unable to accurately reflect inferential practices in natural language.^[99] In Africana philosophy, black nihilism is a negative outlook on discrimination and the possibility of reforming political and social systems to avoid antiblack racism.^[100]

Therapeutic or medical nihilism is the position that medical interventions are largely ineffective. Against the advances of modern medicine, it argues that the methodology of medical research is fundamentally flawed and further distorted by financial incentives, resulting in a systematic overestimation of the benefits of treatments.^[101]

Political nihilism is a negative outlook on existing political and social structures, similar to anarchism. It seeks to uphold individual freedom against oppressive governmental controls and societal norms. Its radical and nihilistic tendencies are expressed in the revolutionary aim to dismantle these established forms of order. It targets political institutions, and the traditional beliefs and social practices supporting them, without offering new systems to take their place.^[102][j]

Political nihilism is mainly linked to the Russian nihilist movement of the late 19th century. It emerged as a reaction to the rigid social structures and authoritarian rule in Tsarist Russia. In their rejection of established institutions and norms, Russian nihilists resorted to extreme means to promote a radical social revolution, leading to forms of violence and terrorism, including assassinations and arson. Some of the revolutionaries saw Turgenev's character Bazarov as their inspiration and role model.^[105]

Although nihilism is primarily associated with modernity, some of its origins trace back to ancient philosophy.^[106] Some Sophists, like Protagoras (c. 490–420 BCE), disputed the existence of objective truth, arguing for a relativistic nihilism according to which "man is the measure of all things".^[107] Socrates's (c. 470–399 BCE) method of radical questioning served as a precursor of nihilism by challenging established beliefs, values, and practices, often with the goal of exposing their lack of a solid foundation.^[108][k] Pyrrho (c. 360–270 BCE) formulated a broad version of epistemological nihilism in his attempt to show that knowledge is impossible.^[110]

Negative attitudes toward objective knowledge and the world are also found in ancient Indian philosophy. However, it is controversial to what extent they constitute forms of nihilism in a strict sense, and some interpreters limit nihilism to the Western tradition.^[111] In the 6th century BCE, the school of Ajñana developed a radical skepticism, questioning the possibility and usefulness of knowledge.^[112] Buddhist thought, starting in the 6th and 5th centuries BCE, focuses on the pervasiveness of suffering, identifying it as a fundamental aspect of existence. It teaches renunciation of worldly desires to achieve liberation from suffering in the state of nirvana.^[113] According to a common interpretation, the school of Mādhyamaka, which emerged in the 2nd century CE, defends metaphysical nihilism, rejecting the existence of an ultimate foundation or absolute reality underlying the multiplicity of experienced phenomena.^[114]

In the early modern period, secularization and the Scientific Revolution undermined established religious beliefs and values prevalent in the Western world during the medieval period, preparing the emergence of nihilism.^[115] René Descartes (1596–1650) considered an extreme form of epistemological nihilism in his quest for absolute certainty. He suggested that humans cannot trust even their most fundamental beliefs unless they can rule out that a malevolent God-like being is constantly deceiving them.^[116] Immanuel Kant (1724–1804) drew a sharp distinction between appearances and things underlying those appearances. By limiting knowledge to the sphere of appearances, he prepared a type of existential nihilism, making the deeper meaning of things in themselves inaccessible.^[117] In criticizing the rationalism of the Kantian philosopher Johann Gottlieb Fichte (1762–1814), Friedrich Jacobi (1743–1819) coined the philosophical concept of nihilism to describe philosophical thought that leads to the denial of existence and meaning.^[118]

In Russia, the term nihilism gained popularity through Ivan Turgenev's (1818–1883) portrayal of the nihilist character Bazarov in his novel Fathers and Sons.^[119] Starting in the second half of the 19th century, the Russian nihilist movement was a form of political nihilism, characterized by a radical rejection of traditional social, political, and aesthetic norms.^[120] Meanwhile in Western Europe, the nihilistic egoism of Max Stirner (1806–1856) reduced other people to their usefulness without respect for their personhood. Stirner also formulated a cosmic nihilism that sees the universe as an unintelligible, metaphysical chaos.^[121] Søren Kierkegaard (1813–1855) explored different lifestyles or "spheres of existence" through which people seek meaning in their lives. He warned against an aesthetic lifestyle of pursuing sensory pleasures without ulterior goals, arguing that it leads to a nihilistic outlook marked by meaninglessness. Instead, he recommended a leap of faith that trusts in God as a higher source of meaning.^[122]

Arthur Schopenhauer (1788–1860) developed a pessimistic philosophy, characterizing the world as a place of suffering, brought into being by a blind, irrational will.^[123] Influenced by Schopenhauer, the problem of nihilism took center stage in the thought of Friedrich Nietzsche (1844–1900). He understood it as a broad cultural phenomenon in which people lose the values and ideals guiding their lives. He explored the causes and consequences of this shift in evaluative outlook, examining reactions to it and ways of overcoming it.^[124] According to Nietzsche, nihilism often manifests in a distorted form as passive nihilism, masking its life-denying nature behind religious dogmas, conventional morality, and societal norms. Against this tendency, Nietzsche recommended active nihilism, which openly acknowledges the lack of meaning and uses its negative force to dismantle established values.^[l] He saw this as a transitional phase to overcome nihilism in general, leading to a vital affirmation of life through a revaluation of all values.^[126]

Many subsequent developments in the 20th-century history of nihilism were responses to Nietzsche's philosophy.^[128] Martin Heidegger (1889–1976) agreed with Nietzsche's description of the pervasive and corrosive nature of nihilism, seeing it as a fundamental historical movement in Western thought reaching back to the ancient period. Interpreting Nietzsche's concept of the will to power and modern technological developments, Heidegger came to the conclusion that Nietzsche's attempt to overcome nihilism fails and leads to an even more complete nihilism. As an alternative, Heidegger turned to early Presocratic philosophy to recover a non-nihilistic understanding of being.^[127]

Bertrand Russell (1872–1970) proposed a view aligned with cosmic nihilism, characterizing humanity as an accidental and insignificant byproduct of cosmic forces that are alien and indifferent to human concerns.^[129] Against the backdrop of World War I, Dadaists expressed aspects of nihilism through art, seeking to undermine established norms and values while embracing nonsense and absurdity.^[130] The question of nihilism and its denial of the meaning of life played a central role for existentialist philosophers.^[131] Jean-Paul Sartre (1905–1980) asserted that humans have no inborn essence defining who they are or what their purpose is. He argued that they can overcome this lack of predefined meaning through freedom, proposing that people make their lives meaningful by inventing themselves and their values.^[23] In his absurdist philosophy, Albert Camus (1913–1960) explored the psychological paradox that arises from the inherent drive to seek meaning in an objectively meaningless world. He termed this condition "the absurd" and advocated for a defiant stance or rebellion against the lack of meaning.^[132]

In the second half of the 20th century, certain aspects of nihilism emerged in postmodern philosophy, often in response to Nietzsche and Heidegger.^[133] Jacques Derrida's (1930–2004) philosophy of deconstruction challenged the existence of absolute truth and stable meaning. Derrida aimed to expose the hidden assumptions and biases on which this viewpoint rests.^[134] Jean-François Lyotard (1924–1998) explored antifoundationalism, rejecting the existence of universal frameworks of understanding, termed metanarratives. He aimed to undermine their validity as standards of truth claims, proposing instead that they are merely different language games people play without a clear hierarchy prioritizing one language game over the others.^[135] Similarly, Richard Rorty (1931–2007) dismissed the notion of objective truths, suggesting that people rely on their own judgment and creativity instead of privileging established perspectives, like the scientific worldview.^[136] Against Nietzsche's and Heidegger's attempts to overcome nihilism, Gianni Vattimo (1936–2023) embraced it, viewing nihilism as the only viable alternative in the postmodern era.^[137]
