Hans-Hermann Hoppe said this quote

Experience cannot beat logic, and interpretations of observational evidence which are not in line with the laws of logical reasoning are no refutation of these but the sign of a muddled mind (or would one accept someone’s observational report that he had seen a bird that was red and non-red all over at the same time as a refutation of the law of contradiction rather than the pronouncement of an idiot?).

Without the continued existence of the democratic system and of publicly funded education and research, however, most current teachers and intellectuals would be unemployed or their income would fall to a small fraction of its present level. Instead of researching the syntax of Ebonics, the love life of mosquitoes, or the relationship between poverty and crime for $100 grand a year, they would research the science of potato growing or the technology of gas pump operation for $20 grand.

In a covenant...among proprietor and community tenants for the purpose of protecting their private property, no such thing as a right to free (unlimited) speech exists, not even to unlimited speech on one’s own tenant-property. One may say innumerable things and promote almost any idea under the sun, but naturally no one is permitted to advocate ideas contrary to the very covenant of preserving and protecting private property, such as democracy and communism. There can be no tolerance toward democrats and communists in a libertarian social order. They will have to be physically separated and removed from society.

With a [democratic] government anyone in principle can become a member of the ruling class or even the supreme power. The distinction between the rulers and the ruled as well as the class consciousness of the ruled become blurred. The illusion even arises that the distinction no longer exists: that with a public government no one is ruled by anyone, but everyone instead rules himself. Accordingly, public resistance against government power is systematically weakened. While exploitation and expropriation before might have appeared plainly oppressive and evil to the public, they seem much less so, mankind being what it is, once anyone may freely enter the ranks of those who are at the receiving end. Consequently, [exploitation will increase], whether openly in the form of higher taxes or discretely as increased governmental money “creation” (inflation) or legislative regulation.
