Ortho language

from Wikipedia, the free encyclopedia

Orthoslanguage is a fundamentally methodical scientific language .

The project to build such a language in which the use of words is standardized comes from Paul Lorenzen as part of the constructive philosophy of science of Erlangen constructivism . It is the attempt to create a “circle-free and vertigo-free” system of terms in order to counteract the confusion of languages. There is a similarity to the standard language ( analytical philosophy ), but the approach of the constructive philosophy of science is based on linguistic action and is not an analytical-deductive description . Nevertheless, Lorenzen sees the ortho language as part of the linguistic turn .

A focus (according to the Logical Propaedeutics ) of the implementation of this program is the modal logical specification of the word “can”. One distinguishes

  1. Possibility according to physical course hypotheses ("natural laws")
  2. Accessibility as a human asset
  3. potential (biological-medical) changes (e.g. growth)
  4. "May" (ethical-political not forbidden )
  5. etc.

The corresponding “must” modalities can also be created for this. Links are interesting here. Example: ultra posse nemo obligatory (lat .: beyond ability (can 2) nobody is obliged (must 4)).

We form purposes of our actions . Technical and political problems arise when ends or means are incompatible. Such incompatibility can also be specified modally logically. Lorenzen defines the political goal of peace as working on mutually compatible forms of life (supreme purposes).
