## Philosophy Lexicon of Arguments | |||

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. | |||

I 34 Logic/Theory/Field: concepts such as negation, conjunction, implication do not require any theoretical access (like e.g. "light is electromagnetic radiation") - because they are logical concepts. --- I 73 Logic/mathematics/mathematical entities/m.e./VsField: one needs mathematical entities in logic, albeit not in science. - FieldVsVs: this is a confusion of logic and meta-logic. - E.g. for definitions in model theory. --- I 74 In logic, which is simple reasoning, we need only the entities that occur in the premises, the intermediate steps, and the conclusions, but because we ultimately draw nominalistic conclusions, we need no mathematical entities in the conclusions. - We are talking about the predictions of empirical consequences. --- I 76 Definition Logic/Field: is the science of the possible. |
