The System of Nature
Template:Short description Template:Italic title Template:Infobox book The System of Nature or, the Laws of the Moral and Physical World (French: {{#invoke:Lang|lang}}) is a 1770 work of philosophy by Paul-Henri Thiry, Baron d'Holbach.
OverviewEdit
The work was originally published under the name of Jean-Baptiste de Mirabaud, a deceased member of the French Academy of Sciences. D'Holbach wrote and published this book – possibly with the assistance of Denis Diderot<ref>See Virgil V. Topazio, "Diderot's Supposed Contribution to D'Holbach's Works", in Publications of the Modern Language Association of America, LXIX, 1, 1954, pp. 173-188.</ref> but with the support of Jacques-André Naigeon – anonymously in 1770, describing the universe in terms of the principles of philosophical materialism: the mind is identified with the brain, there is no "soul" without a living body, the world is governed by strict deterministic laws, free will is an illusion,<ref>System of Nature Vol. 1, Chap XI "Of the System of Man's free agency": "In despite the gratuitous ideas which man has formed to himself on his pretended free-agency; in defiance of the illusions of this suppose intimate sense, which, contrary to his experience, persuades him that he is master of his will, -- all his institutions are really founded upon necessity: on this, as on a variety of other occasions, practice throws aside speculation."</ref> there are no final causes, and whatever happens takes place because it inexorably must. The work explicitly denies the existence of God, arguing that belief in a higher being is the product of fear, lack of understanding, and anthropomorphism.
Though not a scientist himself, d'Holbach was scientifically literate and he tried to develop his philosophy in accordance with the known facts of nature and the scientific knowledge of the day, citing, for example, the experiments of John Needham as proof that life could develop autonomously without the intervention of a deity. It makes a critical distinction between mythology as a more or less benign way of bringing law-ordered thought on society, nature and their powers to the masses and theology. Theology which, when it separates from mythology raises the power of nature above nature itself and thus alienates the two (i.e. "nature", all that actually exists, from its power, now personified in a being outside nature), is by contrast a pernicious force in human affairs without parallel.<ref>System of Nature, Ch.

CriticismEdit
The book was considered extremely radical in its day and the list of people writing refutations of the work was long. The Catholic theologian Nicolas-Sylvestre Bergier wrote a refutation titled Examen du matérialisme ("Materialism examined"). Voltaire, too, seized his pen to refute the philosophy of the {{#invoke:Lang|lang}} in the article "Dieu" in his Dictionnaire philosophique, while Frederick the Great also drew up an answer to it.<ref name = "Openlibrary"/> Commenting on the book, Frederick observed: Template:Quotation
It is speculated that Frederick was motivated to write a criticism of the System of Nature because the book contained an attack not just on religion, but also on monarchy.<ref name = "Will Durant 1965 711"/>
Appreciation and influenceEdit
D'Holbach's friend Denis Diderot had enthusiastically endorsed the book:Template:Quotation
Percy Bysshe Shelley became an ardent atheist after reading The System of Nature, and proceeded to translate the book into English.<ref>Template:Cite book</ref> According to Will Durant, the System of Nature contains the most comprehensive description of materialism and atheism in the entire history of philosophy.<ref>Template:Cite book</ref>
In his student days, Goethe had recoiled with revulsion at the contents in the book: "It appeared to us so grey, so Cimmerian, so corpse – like that we had difficulty in enduring its presence and shuddered before it as before a spectre"; in his old age he harbored similar views: "We belong to the laws of nature, even when we rebel against them."<ref>Template:Cite book</ref>
According to Voltaire, the book was very popular among the populace, including "scholars, the ignorant, and women".<ref name="Will Durant 1965 700" />
