Значи чисто логическият критерий на истината, именно съгласуването на едно познание с общите и формални закони на разсъдъка и разума, е наистина conditio sine qua non. По-нататък обаче логиката не може да отиде и с никакъв пробен камък тя не може да открие грешката, която засяга не формата, а съдържанието.
