Quote from ‘Pragmatism’


[Theō’ric transformation] is an operation of necessary, or rather, of compulsive reasoning, (granted the premisses the interpreter of the reasoning is compelled to assent to the conclusion,) which formal logic cannot possibly take into account, since from the point of view of formal logic there is no essential distinction between it and the most obvious corollarial transformation. Yet the key to mathematical methodeutic lies hidden here. It will consist in the transformation of the problem, – or of its statement, – due to viewing it from another point of view.
