in the series Philosophische Bibliothek, published by Felix Meiner Verlag.25 Misch has written a valuable introduction to this logic, and within certain limits it is quite good on Lotze and on the whole development of logic.
4. Wilhelm Schuppe, Erkenntnistheoretische Logik, 1878.
Lastly a work that is mostly forgotten but that nonetheless is at a high philosophical level, Schuppe’s so-called “epistemological” logic.26
Among the most recent works, I would mention:
5. Alexander Pfänder’s Logik.27
This logic is influenced in an essential way by Husserl. It is elabo-rated phenomenologically, but in such a way that holds to the framework of traditional logic.

Published in 192028both as a separate book and in the fourth volume of the Jahrbuch für Philosophie und phänomenologische Forschung.29

6. Heinrich Rickert.
Heinrich Rickert has been influenced in an essential way by Logical Investigations, and he first revealed the influence, reluctantly, in his article “Zwei Wege der Erkenntnistheorie” [Two Paths of Epistemol-ogy], Kantstudien XI (1909), which became important for his further development. Whatever Rickert has to offer that is new with regard to his earlier position, he essentially owes to Husserl’s investigations.
7. Emil Lask.
Within this same school, Husserl has strongly influenced Lask—Rickert’s student, who was killed in Galicia in 1915. In 1911, Lask
