|Concept: term for an entity with certain properties. The properties of an object correspond to the features of the concept. These concept features are necessary in contrast to the properties of an individual object, which are always contingent._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Concepts/Lyotard/BricmontVsLyotard/SokalVsLyotard/Sokal: Lyotard. (J. F. Lyotard, Das postmoderne Wissen. Ein Bericht. Wien, 1993) often uses terms from physics in a wrong context. Lyotard, like other authors who do not come from the natural sciences, often uses terms from the macroscopic realm and mixes them with findings of quantum mechanics which they have heard of but which refer to the microscopic realm where other laws apply.
For example "density of gases" (Lyotard 1993, p. 165), "fractal geometry",
Sokal I 158
"Non-rerectifiable" (Lyotard 1993, S 172f): Lyotard uses the term in the sense of "non-rectifyable". SokalVsLyotard: in fact it is a property of certain non-differentiable curves.
Sokal I 159
Chaos/Chaos Theory/SokalVsLyotard: the terms "linear" and "nonlinear" are used metaphorically by Lyotard and are applied and transferred prematurely.
Socal I 165
Linearity/Nonlinearity/Postmodernity/Sokal: Authors of so-called "postmodern science" have added other meanings to the terms "linear" and "nonlinear".
Sokal I 166
It is not true that Newton had only linear equations.
Sokal I 167
In contrast, the Schrödinger equation of quantum mechanics is absolutely linear. There are very difficult linear and very simple nonlinear problems. Contrary to popular belief, a non-linear system is not necessarily chaotic._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
