In 1857 the Herbartian philosopher from Bohemia, František Bolemír Květ (1825–1864), published a booklet entitled Leibniz’ens Logik. Květ reconstructed the elements of Leibniz’s scientia generalis stressing the originality of their combination, but not of every single element. He discussed the “extremely meager” fragments concerning the philosophical calculus. They showed, Květ wrote, how far their author stood behind his aims. He dismissed Leibniz’s ars inveniendi, calling it embarrassing because of its weaknesses, defects and impossibility.
