Frederik Wellmann
1864/1865
A. MS.
The attempts to define "logic" suffer from an admixture of logic, anthropology, and psychology. Analysis of the triad of thing, representation, and form. The three kinds of representations: signs, copies, symbols. Conditions to which symbols are subject. The relationship between the syllogism and scientific inference. The proper form of induction. Induction and hypothesis distinguished. Induction increases the extension of subject hypothesis increases the comprehension of predicate. Moreover, induction discovers a law which is a prohibition hypothesis discovers a law which is an imposition.
