Structure (n.) is a kind of organization present only in language (be that the language of the unconscious, of bodies, or of things).
Structure (n.) is defined by the nature of certain atomic elements which account both for the formation of wholes and the variation of their parts.
A Structure (n.) is necessarily unconscious -every structure is an infrastructure, a micro-structure. A structure is not actual, in a way, not actual, what is actual is what the structure constitutes when it is incarnated.
Structure (n.) is a thing having nothing to do with an essence: It is more a combinatory formula [une combinatoire] supporting formal elements which by themselves have neither form, nor signification, nor representation, nor content, nor given empirical reality, nor hypothetical functional model, nor intelligibility behind appearances.
Structure (n.) is a thing having nothing to do with a form: For structure is not at all defined by an autonomy of the whole, by a preeminence [pregnance] of the whole over its parts, by a gestalt which would operate in the real and in perception.
