But even when Leibniz accepts the common way of speaking — that is, as if the senses are causally responsible for some ideas — he has arguments against the empiricist claim that the senses are the origin of all ideas.
A Primer on Substance I consider the notion of substance to be one of the keys to the true philosophy. Here the operative idea is that bodies, and in particular the bodies associated with particular minds, are intentional objects — though they Discourse on metaphysics by leibniz essay from or are grounded in monads.
But one of the most basic principles of his system is that God always acts for the best. Further, since necessary truths are not dependent upon the first free decree of God but are instead revealed by analysis to be identities, they are in fact propositions that are true in all possible worlds.
Therefore, he is another. The distinction that Leibniz draws is one between a real unity and a phenomenal unity, or as he also puts it, between a unum per se and a unum per aggregationem.
According to Leibniz, a possible world also entails certain laws of nature. One could imagine that the motion of the one is communicated through the wooden beam to the other, thus causing them eventually to swing harmoniously the theory of influx.
Indeed, according to Leibniz, the analysis of these concepts can be carried on to infinity. But this opens up the question: The problem, briefly, is this: And, we have also seen that, according to Leibniz, if there were no uniquely best world, then God would not have brought any world into existence.
Or, Leibniz says, one could imagine that God, the supreme artificer, created the world and the pendula so perfectly that, by their own natures, they would swing in perfect harmony. Put differently, the simple substances ground the phenomena of bodies in the world.
The idea here again sounds Aristotelian: Whence comes their agreement? However, there must be a reason that some particular fact is so and not otherwise PSRand, according to Leibniz, this reason is found outside the series of contingent things. Moreover, one series certainly cannot be contained within another, since each and every one of them is complete.
Monads are more or less perfect depending upon the clarity of their perceptions, and a monad is dominant over another when the one contains reasons for what happens in the other.
This is what I meant. The other is necessary only ex hypothesi and, so to speak, accidentally, but it is contingent in itself, since its contrary does not imply a contradiction.
Thus, although diversity in things is accompanied by diversity of time or place, time and place do not constitute the core of identity and diversity, because they [sc.
On his view, God can, as it were, look at the complete individual concept of Alexander and see that he conquered Darius and Porus, that he was the student of Aristotle, that his armies would march into India, and so on. Moreover, if Descartes really did advocate the perfect transparency of the mind, then it should be clear that Leibniz allows for a subtler picture of mental contents: The world-books are on permanent display in the divine intellect.
In other words, a work of fiction represents some way the world could be. This is why the mind of an animal can be said to direct the actions of its body, and why, for example, there will be a hierarchy of functionality within any one animal. In conclusion, it has been claimed throughout this piece that Leibniz advances his unique views on modality in opposition to the views of Hobbes and Spinoza.
Again, if relational properties were allowed to factor into the nature of an individual, then PII would be relatively weak.
We, with our finite minds, are not able to grasp this chain of reasons, but God can do so. There he claims that the Aristotelian idea that a substance is that which is the subject of predication and which cannot be predicated of something else is insufficient for a true analysis of the nature of substance.
Why, after all, should the labyrinth of the nature of freedom be related to infinity? PSR 5 Therefore, our original supposition must be false.
Thus, not only do the mind and body each seem to follow a different set of laws, but the world, according to Leibniz, can be described in terms of either set of laws. Again, each mind-like simple substance represents itself as having a body and a position relative to other bodies, but in doing so each simple substance offers a perspective on the world for the divine mind.
Rather, it is the understanding itself, Leibniz claims, which is the source of such truths and which guarantees their very necessity. In general, we must hold that everything in the world can be explained in two ways: But there may also be individuating essential properties, those which single x out from the other members of the same species and which are nevertheless such that, lacking them, x would no longer be x.Discourse on Metaphysics and Other Essays (Hackett Classics) - Kindle edition by Gottfried Wilhelm Leibniz, Daniel Garber.

In §8 of the Discourse on Metaphysics, Leibniz gives one of his most important accounts of the nature of individual substance. There he claims that the Aristotelian idea that a substance is that which is the subject of predication and which cannot be predicated of something else is insufficient for a true analysis of the nature of substance.
