“ That is, logic is grounded by them, not upon an effete tradition, but upon a new investigation of thought as it actually is in its psychological foundations, in its significance for knowledge and its actual operation in scientific methods. Particular points of logic, again, have received welcome elucidations from more special investigations, and amongst these Windelband’s studies on the negative judgment, Meinong’s treatment of relational-concepts, and Volkelt’s acute and original treatise are most nearly akin to my views. ”

“ In a science which has been so much discussed it seemed to me that to commend or dispute even the most important previous doctrines would be an undue extension of the work; and I further feared lest the course of investigation and exposition prescribed by my view of the subject would be confused if I made a rule of discussing at every point opinions which are to a large extent based upon presuppositions quite different from my own. I have therefore thought it right to confine myself to what was indispensable for the correct representation and justification of my own doctrine. ”

“ AUTHOR'S PREFACE TO THE ENGLISH TRANSLATION
When I was requested to give my consent to an English translation of my Logic, I complied willingly, because in preparing and achieving this work an essential part of my studies had been devoted to English logicians from Francis Bacon down to Jevons, Bradley, and Venn; thus I may hope that to English readers my book will not appear entirely as a foreigner.
Whoever has himself attempted to translate a philosophical treatise is acquainted with the difficulties of the task ”
