“Human nature is said by many to be good; if so, where have social evils come from? For human nature is the only moral nature in that corrupting thing called "society." Every example set before the child of to-day is the fruit of human nature. It has been planted on every possible field — among the snows that never melt; in temperate regions, and under the line; in crowded cities, in lonely forests; in ancient seats of civilization, in new colonies; and in all these fields it has, without once failing, brought forth a crop of sins and troubles.”

2000s, The Central Idea (2006)
Context: The equality of mankind is best understood in light of a two-fold inequality. The first is the inequality of mankind and of the subhuman classes of living beings that comprise the order of nature. Dogs and horses, for example, are naturally subservient to human beings. But no human being is naturally subservient to another human being. No human being has a right to rule another without the other's consent. The second is the inequality of man and God. As God's creatures, we owe unconditional obedience to His will. By that very fact however we do not owe such obedience to anyone else. Legitimate political authority—the right of one human being to require obedience of another human being—arises only from consent. The fundamental act of consent is, as the 1780 Massachusetts Bill of Rights states, "a social compact by which the whole people covenants with each citizen and each citizen with the whole people that all shall be governed by certain laws for the common good." The "certain laws for the common good" have no other purpose but to preserve and protect the rights that each citizen possesses prior to government, rights with which he or she has been "endowed by their Creator." The rights that governments exist to secure are not the gift of government. They originate in God.

As quoted in Carl Reinhold Bråkenhielm (2009), "Linnaeus and homo religiosus," Universitet, p. 83.

Il est à peu près impossible de constituer systématiquement une morale naturelle. La nature n'a pas de principes. Elle ne nous fournit aucune raison de croire que la vie humaine est respectable. La nature, indifférente, ne fait nulle distinction du bien et du mal.
La Révolte des Anges [The Revolt of the Angels] (1914), ch. XXVII

Die Natur baut keine Maschinen, keine Lokomotiven, Eisenbahnen, electric telegraphs, selfacting mules etc. Sie sind Produkte der menschlichen Industrie; natürliches Material, verwandelt in Organe des menschlichen Willens über die Natur oder seiner Betätigung in der Natur. Sie sind von der menschlichen Hand geschaffene Organe des menschlichen Hirns; vergegenständliche Wissenskraft. Die Entwicklung des capital fixe zeigt an, bis zu welchem Grade das allgemeine gesellschaftliche Wissen, knowledge, zur unmittelbaren Produktivkraft geworden ist und daher die Bedingungen des gesellschaftlichen Lebensprozesses selbst unter die Kontrolle des general intellect gekommen, und ihm gemäß umgeschaffen sind.

Source: Anarcho-Syndicalism (1938), Ch. 1 "Anarchism: Its Aims and Purposes"
Context: Anarchism recognises only the relative significance of ideas, institutions, and social conditions. It is, therefore not a fixed, self enclosed social system, but rather a definite trend in the historical development of mankind, which, in contrast with the intellectual guardianship of all clerical and governmental institutions, strives for the free unhindered unfolding of all the individual and social forces in life. Even freedom is only a relative, not an absolute concept, since it tends constantly to broaden its scope and to affect wider circles in manifold ways. For the Anarchist, freedom is not an abstract philosophical concept, but the vital concrete possibility for every human being to bring to full development all capacities and talents with which nature has endowed him, and turn them to social account. The less this natural development of man is interfered with by ecclesiastical or political guardianship, the more efficient and harmonious will human personality become, the more will it become the measure of the intellectual culture of the society in which it has grown.

The Farmer Refuted (1775)
Context: The fundamental source of all your errors, sophisms, and false reasonings, is a total ignorance of the natural rights of mankind. Were you once to become acquainted with these, you could never entertain a thought, that all men are not, by nature, entitled to a parity of privileges. You would be convinced, that natural liberty is a gift of the beneficent Creator, to the whole human race; and that civil liberty is founded in that; and cannot be wrested from any people, without the most manifest violation of justice. Civil liberty is only natural liberty, modified and secured by the sanctions of civil society. It is not a thing, in its own nature, precarious and dependent on human will and caprice; but it is conformable to the constitution of man, as well as necessary to the well-being of society.
