Performative Knowledge.

The article discusses the notion of performativity as part of the movement against the notion of 'thinking' by René Descartes which is an argument of co-extensivity. The author points out that the notion of performativity names an approach that refuses to tie the fact that 'there is thinking' to identity or ontology. She adds that to speak of performativity in relation to the subject of subjectivity is to focus on the practices of this conditioned element within the various matrices by which it is sustained. The author quotes Judith Butler's thesis which interrogates differentiated subject formation within practices that sustain lines of power and power effects.
