“All the different classes of beings which taken together make up the universe are, in the ideas of God who knows distinctly their essential gradations, only so many ordinates of a single curve so closely united that it would be impossible to place others between any two of them, since that would imply disorder and imperfection. Thus men are linked with the animals, these with the plants and these with the fossils which in turn merge with those bodies which our senses and our imagination represent to us as absolutely inanimate.” KnowsMenTwoIdeasDifferentBodyWould BeTogetherTurnsUniverseImaginationAnimalUnitedClassTakenImpossibleEssentialsPlantSensesDisorderImperfectionLinkedCurvesFossils Author:Gottfried Leibniz
“Let there be two possible things, A and B, one of which is such that it is necessary that it exists, and let us assume that there is more perfection in A than in B. Then, at least, we can explain why A should exist rather than B and can foresee which of them will exist; indeed, this can be demonstrated, that is, rendered certain from the nature of the thing.” ShouldTwoCertainPerfectionAssuming Author:Gottfried Leibniz
“There are two famous labyrinths where our reason very often goes astray. One concerns the great question of the free and the necessary, above all in the production and the origin of Evil. The other consists in the discussion of continuity, and of the indivisibles which appear to be the elements thereof, and where the consideration of the infinite must enter in.” TwoReasonEvilElementsConcernInfiniteProductionsDiscussionConsiderationContinuityLabyrinth Author:Gottfried Leibniz
“There are also two kinds of truths, those of reasoning and those of fact. Truths of reasoning are necessary and their opposite is impossible, and those of fact are contingent and their opposite is possible. When a truth is necessary its reason can be found by analysis, resolving it into more simple ideas and truths until we reach those which are primitive.” KindTwoIdeasReasonFactsScienceFoundSimpleImpossibleTruth IsOppositesPrimariesAnalysisReasoningSimple Ideas Author:Gottfried Leibniz

“Indeed every monad must be different from every other. For there are never in nature two beings, which are precisely alike, and in which it is not possible to find some difference which is internal, or based on some intrinsic quality.” TwoDifferentDifferencesQualityWords Of WisdomInternals Author:Gottfried Leibniz
“Our reasonings are grounded upon two great principles, that of contradiction, in virtue of which we judge false that which involves a contradiction, and true that which is opposed or contradictory to the false.” TwoSciencePrinciplesVirtueJudgingReasoningContradictionGroundedContradictory Author:Gottfried Leibniz
