It was founded circa 1958 – 1959 after the publication of its ( first ) holy book the Principia Discordia, written by Malaclypse the Younger and Omar Khayyam Ravenhurst after a series of shared hallucinations at a bowling alley.

It is specified on page 00034 of the Principia Discordia.

Elsewhere in the Principia Discordia, it is mentioned that the Curse of Greyface occurred in 1166 BC, so this is presumably the start-date of the calendar.

The Principia Discordia states that her parents may be as described in Greek legend, or that she may be the daughter of Void.

Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica, which states:

The Principia states Newton's laws of motion, forming the foundation of classical mechanics, also Newton's law of universal gravitation, and a derivation of Kepler's laws of planetary motion ( which Kepler first obtained empirically ).

* The second edition of Isaac Newton's Principia Mathematica is published with an introduction by Roger Cotes and an essay by Newton titled General Scholium where he famously states " Hypotheses non fingo " (" I feign no hypotheses ").

Except for correspondence with Flamsteed we hear nothing more of the preparation of the Principia until April 21, 1686, when Halley read to the Royal Society his Discourse concerning Gravity and its Properties, in which he states " that his worthy countryman Mr Isaac Newton has an incomparable treatise of motion almost ready for the press ," and that the law of the inverse square " is the principle on which Mr Newton has made out all the phenomena of the celestial motions so easily and naturally, that its truth is past dispute.

" All Rights Reversed " ( sometimes spelled rites ) was used by author Gregory Hill to authorize the free reprinting of his Principia Discordia in the late 1960s.

With the Discours de la methode and the Principia the things undreamt of in Horatio's philosophy seem to pass from the world.

Moore's argument in Principia Ethica is ( among other things ) a defense of ethical non-naturalism ; he argues that the term " good " ( in the sense of intrinsic value ) is indefinable, because it names a simple, non-natural property.

It was perhaps the force of the ' Principia ', which revealed so many different things about the natural world with such economy, that caused this method to become synonymous with physics, even as it is practiced almost three and a half centuries after its beginning.

In his doctoral thesis, Post proved, among other things, that the propositional calculus of Principia Mathematica was complete: all tautologies are theorems, given the Principia axioms and the rules of substitution and modus ponens.

Trilogy ( therein called the " 23 / 17 phenomenon "), Wilson's Cosmic Trigger I: The Final Secret of the Illuminati ( therein called " The Law of fives " and " The 23 Enigma "), Arthur Koestler's Challenge of Chance, as well as the Principia Discordia.

However, shortly after this positive result, Kurt Gödel published On Formally Undecidable Propositions of Principia Mathematica and Related Systems ( 1931 ), showing that in any sufficiently strong axiomatic system there are true statements which cannot be proved in the system.

Moore dealt with casuistry in chapter 1. 4 of his Principia Ethica ; he claimed that " the defects of casuistry are not defects of principle ; no objection can be taken to its aim and object.

Newton corrected in the second edition of his Principia an error pointed out by Abauzit, and, when sending him the Commercium Epistolicum, said, " You are well worthy to judge between Gottfried Leibniz and me.

Among Moore's most famous works are his book Principia Ethica, and his essays, " The Refutation of Idealism ", " A Defence of Common Sense ", and " A Proof of the External World ".

( In Principia Mathematica, formulas and propositions are identified by a leading asterisk and two numbers, such as "✸ 2. 1 ".

It is, rather, " one of those innumerable objects of thought which are themselves incapable of definition, because they are the ultimate terms by reference to which whatever is capable of definition must be defined " ( Principia Ethica § 10 ¶ 1 ).

Thus, the statement " there are no contradictions in the Principia system " cannot be proven in the Principia system unless there are contradictions in the system ( in which case it can be proven both true and false ).

However, it is our everyday arithmetical practices such as counting which are fundamental ; for if a persistent discrepancy arose between counting and Principia, this would be treated as evidence of an error in Principia ( e. g., that Principia did not characterize numbers or addition correctly ), not as evidence of an error in everyday counting.

Extracts from its sacred text, the Principia Discordia by Malaclypse the Younger, are extensively quoted throughout the trilogy.

The ' Principia ' deals primarily with massive bodies in motion, initially under a variety of conditions and hypothetical laws of force in both non-resisting and resisting media, thus offering criteria to decide, by observations, which laws of force are operating in phenomena that may be observed.

The process of writing that first edition of the Principia went through several stages and drafts: some parts of the preliminary materials still survive, others are lost except for fragments and cross-references in other documents.

Stanisław Leśniewski was perhaps the first to make widespread use of this distinction or fallacy, seeing it all around in analytic philosophy of the time, for example in Russell's Principia Mathematica ; at the logical level, a use – mention mistake occurs when two heterogeneous levels of meaning or context are confused inadvertently.

Among Dupin's works, which are numerous, may be mentioned Principia Juris Civilis, 5 vols.

These are the prerequisite basics of Newtonian mechanics, a series of statements and equations in Philosophiae Naturalis Principia Mathematica originally published in 1687.

It occupies twenty-four octavo pages, and consists of four theorems and seven problems, some of which are identical with some of the most important propositions of the second and third sections of the first book of the Principia.

This approach was continued by Russell and Whitehead in their influential Principia Mathematica, first published 1910-1913, and with a revised second edition in 1927.

More ambitious was the Logic Theory Machine, a deduction system for the propositional logic of the Principia Mathematica, developed by Allen Newell, Herbert A. Simon and J. C. Shaw.

In the eighteenth century the same possibility was mentioned by Isaac Newton in the " General Scholium " that concludes his Principia.

The concept of Eris as developed by the Principia Discordia is used and expanded upon in the science fiction work The Illuminatus!

Trilogy by Robert Shea and Robert Anton Wilson ( in which characters from Principia Discordia appear ).

The principle was stated as a theorem of propositional logic by Russell and Whitehead in Principia Mathematica as:

The principle was stated as a theorem of propositional logic by Russell and Whitehead in Principia Mathematica as:

They were first compiled by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica, first published on July 5, 1687.

Another usage of the phrase was described by British philosopher G. E. Moore in his 1903 book Principia Ethica.

Another usage of the phrase was described and named by British philosopher G. E. Moore in his 1903 book Principia Ethica.

The two-body solutions were published by Newton in Principia in 1687.

The Principia Mathematica is a three-volume work on the foundations of mathematics, written by Alfred North Whitehead and Bertrand Russell and published in 1910, 1912, and 1913.

However, this is not the stronger sense of completeness desired for Principia Mathematica, since a given system of axioms ( such as those of Principia Mathematica ) may have many models, in some of which a given statement is true and in others of which that statement is false, so that the statement is left undecided by the axioms.

It was followed, in 1644, by Principia Philosophiæ ( Principles of Philosophy ), a kind of synthesis of the Meditations and the Discourse.

A French translation of Principia Philosophiæ, prepared by Abbot Claude Picot, was published in 1647.

Principia philosophiae ( Principles of Philosophy ), a Latin textbook at first intended by Descartes to replace the Aristotelian textbooks then used in universities.

* One of the title pages of Principia Discordia, a co-author of which went by the pen-name Omar Khayyam Ravenhurst, features its own spin on the quatrain most quoted above:

In the Axioms Scholium of his Principia Newton said its axiomatic three laws of motion were already accepted by mathematicians such as Huygens ( 1629 – 1695 ), Wallace, Wren and others, and also in memos in his draft preparations of the second edition of the Principia he attributed its first law of motion and its law of gravity to a range of historical figures.
