"There can be no knowledge of what is good for man apart from knowledge of reality and human nature, and there is no manner in which this knowledge can be acquired except through reason. To advocate irrationality is to advocate that which is destructive to human life."

“To enumerate the particular details—the sufficient conditions—of a good society is effectively to prohibit individuality and social change. A planned society, a society in which sufficient conditions are politically determined and coercively imposed, is ‘closed’ to the spontaneous innovations of free association. We see this in the utopian writings of Plato and his many admirers. A utopian society is a perfect society, one that has been carefully designed by a wise and beneficent lawgiver. Any deviation from perfection must necessarily be for the worse, so social change—which in this scheme is but another name for social degeneration—must be arrested at all costs. And this, in turn, requires the suppression of individuality. The individual’s pursuit of happiness—that powerful and unpredictable agent of social change—must be subordinated for the sake of a good society, as specified in the utopian blueprint of sufficient conditions.”

“Those in government are especially susceptible to the corruption of power, because government is institutionalized coercion.”

“According to this approach, legitimate disagreements may occur between subjects and rulers when alienable rights are involved, but no such disputes are justified over the question of inalienable rights. Government cannot claim any jurisdiction over such rights, because inalienable rights, by their very nature, could never have been transferred to government in the first place.”

“In the late nineteenth century, liberals in Europe and America discovered that they were victims of a linguistic coup. They found that they were no longer regarded as liberals per se but as old liberals – a qualification that had bed foisted upon them by self-proclaimed new liberals.”

“When conformity is required, as it is in Christianity, what are the results? To begin with, the sacrifice of truth inevitably follows. One can be committed to conformity or one can be committed to truth, but not both. The pursuit of truth requires the unrestricted use of one's mind—the moral freedom to question, to examine evidence, to consider opposing viewpoints, to criticize, to accept as true only that which can be demonstrated—regardless whether one's conclusions conform to a particular creed.”

“Taxes forcibly transfer wealth from producers to legislators, who justify their expropriations under cover of law.”
