|Logic: logic is the doctrine of the admissibility or inadmissibility of relations between statements and thus the validity of the compositions of these statements. In particular, the question is whether conclusions can be obtained from certain presuppositions such as premises or antecedents. Logical formulas are not interpreted at first. Only the interpretation, i. e. the insertion of values, e.g. objects instead of the free variables, makes the question of their truth meaningful.|

Logic/Theory/Observation/Feyerabend: good ideas can become endangered by bad test procedures. Then a purely logical method, which puts all sentences on the same level, is naïve and hinders progress. Marx saw this clearly.
Logic/Feyerabend: there is a dogma that all areas, how ever they may be composed, entirely obey the laws of logic.
FeyerabendVs: if this were correct, the anthropological fieldwork would, of course, be superfluous. But it is not clear why the different areas should have a uniform logic. They do not merely provide different interpretations of one and the same set of logical "facts," but different "facts".
In addition, there are statements that obviously contradict logic: E.g. illusions.
Methodology/Logic/Feyerabend: exclude too much, they are too narrow. In between lies the ever-changing kingdom of human ideas and desires.
