Irrationality in the context of "Apollonian and Dionysian"

Enlightenment philosophy was the philosophy produced during the Age of Enlightenment (late 17th and 18th centuries), originating in France, then western Europe and spreading throughout the rest of Europe. The Enlightenment philosophers included (among others) Baruch Spinoza, David Hume, John Locke, Edward Gibbon, Voltaire, Jean-Jacques Rousseau, Denis Diderot, Pierre Bayle, and Isaac Newton. Enlightenment philosophy was influenced by the Scientific Revolution in southern Europe, arising directly from the Italian Renaissance with people like Galileo Galilei.

Enlightenment philosophers saw themselves as a progressive élite, and battled against religious persecution and political persecution, fighting against what they saw as the irrationality, arbitrariness, obscurantism and superstition of the previous centuries. They redefined the study of knowledge to fit the ethics and aesthetics of their time. Their works had great influence at the end of the 18th century, in the American Declaration of Independence and the French Revolution.

Paranoia is an instinct or thought process that is believed to be heavily influenced by anxiety, suspicion, or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself (e.g., "Everyone is out to get me"). Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame.

Making false accusations and the general distrust of other people also frequently accompany paranoia. For example, a paranoid person might believe an incident was intentional when most people would view it as an accident or coincidence. Paranoia is a central symptom of psychosis.

A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality.

While cognitive biases may initially appear to be negative, some are adaptive. They may lead to more effective actions in a given context. Furthermore, allowing cognitive biases enables faster decisions which can be desirable when timeliness is more valuable than accuracy, as illustrated in heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), the impact of an individual's constitution and biological state (see embodied cognition), or simply from a limited capacity for information processing. Cognitive biases can make individuals more inclined to endorsing pseudoscientific beliefs by requiring less evidence for claims that confirm their preconceptions. This can potentially distort their perceptions and lead to inaccurate judgments.

Absurdity is the state or condition of being unreasonable, meaningless, or so unsound as to be irrational. "Absurd" is the 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 nonsense, meaninglessness, fancifulness, foolishness, bizarreness, wildness. 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.

Absurdism is the philosophical theory that the universe is irrational and meaningless. It states that trying to find meaning leads people into conflict with a seemingly meaningless world. This conflict can be between rational humanity and an irrational universe, between intention and outcome, or between subjective assessment and objective worth, but the precise definition of the term is disputed. Absurdism claims that, due to one or more of these conflicts, existence as a whole is absurd. It differs in this regard from the less global thesis that some particular situations, persons, or phases in life are absurd.

Various components of the absurd are discussed in the academic literature, and different theorists frequently concentrate their definition and research on different components. On the practical level, the conflict underlying the absurd is characterized by the individual's struggle to find meaning in a meaningless world. The theoretical component, on the other hand, emphasizes more the epistemic inability of reason to penetrate and understand reality. Traditionally, the conflict is characterized as a collision between an internal component of human nature, and an external component of the universe. However, some later theorists have suggested that both components may be internal: the capacity to see through the arbitrariness of any ultimate purpose, on the one hand, and the incapacity to stop caring about such purposes, on the other hand. Certain accounts also involve a metacognitive component by holding that an awareness of the conflict is necessary for the absurd to arise.

A cognitive distortion is a thought that causes a person to perceive reality inaccurately due to being exaggerated or irrational. Cognitive distortions are involved in the onset or perpetuation of psychopathological states, such as depression and anxiety. Cognitive distortions are negative or biased thought patterns that distort one’s perception of reality, often leading to unnecessary stress, anxiety, or self-doubt. These distortions, such as mind reading, fortune telling, and emotional reasoning, warp the way individuals interpret situations and themselves, reinforcing negative emotions and behaviors. Understanding and challenging these distortions is crucial in cognitive-behavioral therapy (CBT) to help individuals overcome them and improve their mental well-being.

According to Aaron Beck's cognitive model, a negative outlook on reality, sometimes called negative schemas (or schemata), is a factor in symptoms of emotional dysfunction and poorer subjective well-being. Specifically, negative thinking patterns reinforce negative emotions and thoughts. During difficult circumstances, these distorted thoughts can contribute to an overall negative outlook on the world and a depressive or anxious mental state. According to hopelessness theory and Beck's theory, the meaning or interpretation that people give to their experience importantly influences whether they will become depressed and whether they will experience severe, repeated, or long-duration episodes of depression.

Psychic surgery is a medical fraud in which practitioners create the illusion of performing surgery with their bare hands and use sleight of hand, fake blood, and animal parts to convince the patient that diseased lesions have been removed and that the incision has spontaneously healed. The technique may fool the general public, but it can be observed by experienced stage magicians, who use the same sleight of hand techniques for entertainment.

The US Federal Trade Commission described psychic surgery as a "total hoax". It has also been described as fraud, fakery, deceitful, irrational, charlatanry, and quackery. Even supporters have been forced to admit that sleight-of-hand tricks were "widely used" and that charlatans were common and miracles unlikely. Psychic surgery may cause needless death by keeping the ill away from life-saving medical care. Medical professionals and skeptics classify it as sleight of hand and any positive results as a placebo effect.

Fanaticism is a belief or behavior involving uncritical zeal or an obsessive enthusiasm. The political theorist Zachary R. Goldsmith provides a "cluster account" of the concept of fanaticism, identifying ten main attributes that, in various combinations, constitute it: messianism, inappropriate relationship to reason (irrationality), an embrace of abstraction, a desire for novelty, the pursuit of perfection, an opposition to limits, the embrace of violence, absolute certitude, excessive passion, and an attractiveness to intellectuals.
