Christoph von Sigwart,
Logic — Author's Preface to Second German Edition
(1895)
“ 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. ”
