QUOTE : I have shown [the categorial imperative] to be a futile assumption so clearly and irrefutably, that no one with a spark of judgment can possibly believe any longer in this fiction. - "well, and so [the Kantian professors have probably engaged with your critique of the categorial imperative]." - Oh no! They take good care not to venture on such slippery ground! Their ability consists in holding their tongues; silence is all they have to oppose to intelligence, earnestness, and truth. In not one of the products of their useless scribblings that have appeared since 1841, has the slightest notice been taken of my Ethics - undoubtedly the most important work on Moral Philosophy that has been published for the last sixty years - nay, their terror of me and of my truth is so great, that none of the literary journals issued by Academies or Universities has so much as mentioned [my] book. Zitto, zitto, lest the public should perceive anything: in this consists the whole of their policy. The instinct of self-preservation may, no doubt, be at the bottom of these artful tactics.
