Jacques Derrida is widely regarded as the father of post-structuralism, a philosophical movement that emerged in the mid-20th century.

Post-structuralists argue that the meaning of a text is not fixed or objective, but rather is constructed by the reader through their own unique experiences and interpretations.

Deconstruction is a method of interpreting texts that emphasizes their multiple and contradictory meanings, rather than seeking to uncover a single, true meaning.

Post-structuralists argue that discourse and power are mutually constitutive, meaning that they shape and influence each other.

The concept of the 'death of the author' in post-structuralism refers to the idea that the author's intention is not the only valid interpretation of a text, and that the meaning of a text is created by the reader.

Michel Foucault argued that the concept of truth is a product of power relations, and that what is considered true is often determined by those in positions of power.

The concept of the 'rhizome' in post-structuralism is a metaphor for the interconnectedness of knowledge and meaning, and the idea that there is no single, fixed hierarchy of knowledge.

Judith Butler argued that the concept of the 'self' is a product of discourse, and that the way we understand ourselves and our identities is shaped by the cultural and social norms in which we live.

The concept of 'difference' in post-structuralism emphasizes the importance of recognizing and respecting differences between individuals and groups, and the idea that there is no single, universal norm or standard.

Jacques Derrida argued that the concept of 'logocentrism' is a form of oppression, as it privileges written language and reason over other forms of communication and knowledge.

Post-structuralism is generally considered to be a branch of postmodernism, as it shares many of the same assumptions and critiques.

Jean Baudrillard argued that the concept of 'the real' is a product of discourse, and that what we consider to be real is often mediated by images and representations.

The concept of 'the simulacrum' in post-structuralism refers to a representation of something that does not exist, and the idea that reality is often mediated by images and representations that are not necessarily true or accurate.

Laura Mulvey argued that the concept of 'the gaze' is a form of power, as it is often used to objectify and control women.
