"The Dialectic of Knowledge" is notion my Jacques Lacan which describes the manner in which knowledge, any form of knowledge, is organized. According to Lacan knowledge is always dialectic by being organized in a set of oppositions (Lacan took this notion from the structuralist thought). Lacan distinguishes Savoir, knowledge, and Connaissance, consciousness. Knowledge is part of the Symbolic Order while consciousness is associated with Imaginary Order. This means that there is always an inner gap in everything we know, and that all knowledge is always dis-knowledge and conscious and always also mis-conscious.
