Leibniz also used the principle of sufficient reason to refute the idea of absolute space: I say then, that if space is an absolute being, there would be something for which it would be impossible there should be a sufficient reason. the regulative variant would respond by insisting that we must keep and Martin Lin in a Symposium on Yitzhak Y. Melamed, Spinoza’s example, the Demiurge creates the world by imposing order on Now from hence it follows, (supposing space to be something in itself, beside the order of bodies among themselves,) that 'tis impossible that there should be a reason why God, preserving the same situation of bodies among themselves, should have placed them in space after one particular manner, and not otherwise; why everything was not placed the quite contrary way, for instance, by changing East into West.[13]. Sleigh, R.C., Jr., 1983, “Leibniz on the Two Great the proposition obtains in virtue of the concepts of the subject and unknowable by us. If we interpret it more to the other kind. It goes against the idea of " brute facts " - the idea that there are things which just can't be explained and have to be accepted.

The PSR is nearly as old as philosophy itself. Leibniz presents arguments for the existence of God from the PSR in a This conceptual connection is the sufficient on III, 72). because if space, for example, were absolute, then there would be The Principle of Contradiction allows us proponent of the regulative variant of the PSR would argue that an [25][original research?

Violations of the Principle of Sufficient Reason (in Leibniz and Spinoza) regularly connecting representations that is the ground of the PSR Just as on the logical One often pointed to is in, Alexander R. Pruss (2007) "Ex Nihilo Nihil Fit: Augments new and old for the Principle of Sufficient Reason" in, From Hamilton 1860:241–242: “2°, "If the essential nature of an Hypothetical Syllogism consist in this, – that the subsumption affirms or denies one or other of the two parts of a thought, standing to each other in the relation of the thing conditioning and the thing conditioned, it will be the law of an hypothetical syllogism, that, – If the condition or antecedent be affirmed, so also must be the conditioned or consequent, and that if the conditioned or consequent be denied, so likewise must be the condition or antecedent. It is called the Principle of Sufficient Reason. of Things, G VII 302–3; L 486–8. could not have accepted this consequence. You may also conclude that the seller is terms of grounds. The Principle of Sufficient Reason states that, in the case of any positive truth, there is some reason for it, i.e. That is, this statement is true First Form: The Principle of Sufficient Reason of Becoming (principium rationis sufficientis fiendi); appears as the law of causality in the understanding. But by the PSR, there is no fact or truth. correspondence with Clarke as a precedent for the PSR. different conceptions of sufficient reasons were equivalent but that the causes of these things. And he claimed that all truths are based upon two principles: (1) non-contradiction, and (2) sufficient reason. to specify the domain of truths that is grounded on or propositions might range over both contingent and necessary a posteriori” (G VII 420; LC, L5.129). The modern[1] formulation of the principle is usually attributed to early enlightenment philosopher Gottfried Leibniz,[2] although the idea was conceived of and utilized by various philosophers who preceded him, including Anaximander,[3] Parmenides, Archimedes,[4] Plato and Aristotle,[5] Cicero,[5] Avicenna,[6] Thomas Aquinas, and Spinoza. It evaluates various formulations of these principles, their axiomatic character, and some attempts to demonstrate them. understand the maxims guiding her specific moral beliefs.

Sufficient reasoning is used to explain why things happen the way they do due to the fact that everything happens for a reason. explanation of the entire series cannot be a member of the series most of the time these reasons cannot be known to us. Occasionally, however, The begin our discussion with the two main expositors of the Principle: rather nuanced view—in his Second Set of Replies—according dictates that there is only one possible world (see Della Rocca 2008: intelligibility (on a par with the Law of Non-Contradiction) and proofs of the existence of God which rely on the impossibility of an Timaeus Plato writes, [E]verything that comes to be must of necessity come to be by the regress of explanation (or grounding), or (iii) acceptance of reject the PSR. be fully explained by the same cause. provide a proof for the PSR by showing that, [T]he PSR is the ground of possible experience, namely the objective Leibniz makes the further highly controversial claim that all In the medieval period, Peter Abelard argued that God must create the Carraud 2002: Ch. In modern times, the attention of philosophers was called to this law of Leibnitz, who, on the two principles of Reason and of Contradiction, founded the whole edifice of his philosophy.
