Ferdinand de Saussure is widely recognized as the founder of structuralism, a school of thought that emphasizes the underlying structures and systems that shape language, culture, and society.

The central concept of structuralism is the sign, which consists of a signifier (the physical form of the sign) and a signified (the mental concept or idea that the sign represents).

The goal of structuralist analysis is to reveal the underlying structures and systems that shape a text or cultural artifact, rather than to interpret its meaning or evaluate its aesthetic value.

Deconstruction is a method of literary analysis that emphasizes the instability and indeterminacy of meaning, arguing that texts are always open to multiple interpretations and that there is no single, correct meaning.

Jacques Derrida is widely recognized as the founder of deconstruction, a school of thought that emphasizes the instability and indeterminacy of meaning.

The central concept of deconstruction is the free play of signifiers, the idea that signifiers are not fixed to a single meaning but can instead slide and shift, creating multiple and often contradictory meanings.

The goal of deconstructive analysis is to reveal the instability and indeterminacy of meaning, rather than to reveal the underlying structures of a text or cultural artifact, interpret its meaning, or evaluate its aesthetic value.

Structuralism emphasizes the stability and fixity of meaning, arguing that texts have a single, correct meaning that can be discovered through analysis of their underlying structures. Deconstruction, on the other hand, emphasizes the instability and indeterminacy of meaning, arguing that texts are always open to multiple interpretations and that there is no single, correct meaning.

Roland Barthes is associated with the concept of "the death of the author," which argues that the author's intention is irrelevant to the interpretation of a text and that the meaning of a text is created by the reader.

Julia Kristeva is associated with the concept of "intertextuality," which argues that all texts are interconnected and that the meaning of a text is shaped by its relationship to other texts.

Jean-François Lyotard is associated with the concept of "the postmodern condition," which argues that we live in a time characterized by the breakdown of traditional values and beliefs and the rise of new forms of knowledge and culture.

Gilles Deleuze and Félix Guattari are associated with the concept of "the rhizome," which is a non-hierarchical, non-linear model of knowledge and culture that emphasizes the interconnectedness of all things.

Jean Baudrillard is associated with the concept of "the simulacrum," which is a copy or imitation that has no original and that therefore exists in a state of hyperreality.

Guy Debord is associated with the concept of "the spectacle," which is a form of social control that uses images and symbols to manipulate people's thoughts and behaviors.

Michel Foucault is associated with the concept of "the panopticon," which is a type of prison designed to allow the guards to observe all of the prisoners at all times without being seen themselves.
