Leibniz — Why Must Substance be Indivisible/unified?

Why does Leibniz think there must be simple substances?

In Monadology Leibniz says that “there must be simple substances, since there are composites; for the composite is nothing more than a collection, or aggregate, of simples” (Monadology, par. 2; AG, 213). And because these simples have no parts, they cannot have extension either.

What is substance according to Leibniz?

According to Leibniz, substances are not only essentially unities, but also active. As he says in the opening line of the Principles of Nature and Grace: “A Substance is a being capable of action” (G VI 598/AG 207).

What did Leibniz say about free will?

For Leibniz, this means that human action is further freed: the will has the power to suspend its action with respect to the physical sequence of efficient causes, but also even with respect to what would otherwise be seen as a decisive final cause.

What is perception for Leibniz?

It is arguably for this reason that Leibniz defines ‘perception’ as “the passing state which involves and represents a multitude in the unity or in the simple substance” (Monadology, section 14). Leibniz’s mill argument, then, relies on a particular understanding of perception and of material objects.

Why does Gottfried Leibniz claim that reason is more important and more reliable than sense data?

For Leibniz, God’s rational ordering of creation certifies the reliability of sense perception, since God—the most rational of all minds—cannot do anything without having a reason for doing so.

What did Gottfried Leibniz believe in?

Leibniz believed that the best of all possible worlds would actualize every genuine possibility, and argued in Théodicée that this best of all possible worlds will contain all possibilities, with our finite experience of eternity giving no reason to dispute nature’s perfection.

Does Leibniz believe in God?

G. W. Leibniz (1646-1716) thought the same as you: belief in God must have a rational basis, not a basis in faith alone. So he disagreed with Bayle. But this meant that Leibniz had to face the problem of natural evil head on (a task he called “theodicy”, which literal means God’s justification).

What is Leibniz’s principle of sufficient reason?

The principle of sufficient reason states that everything must have a reason or a cause. The principle was articulated and made prominent by Gottfried Wilhelm Leibniz, with many antecedents, and was further used and developed by Arthur Schopenhauer and Sir William Hamilton, 9th Baronet.

What does Leibniz mean by freedom?

The rational ability to determine our actions in light of the true value of the potential outcomes of our actions is thus, Leibniz suggests, the very heart of freedom in its fullest sense. Leibniz nonetheless allows that in our current state we seldom, if ever, choose under conditions of perfect intellectual clarity.

Why is being free important?

Freedom is a condition in which people have the opportunity to speak, act and pursue happiness without unnecessary external restrictions. Freedom is important because it leads to enhanced expressions of creativity and original thought, increased productivity, and an overall high quality of life.

Do Compatibilists believe in determinism?

Compatibilism is the belief that free will and determinism are mutually compatible and that it is possible to believe in both without being logically inconsistent. Compatibilists believe that freedom can be present or absent in situations for reasons that have nothing to do with metaphysics.

What exactly is the philosophical problem that Leibniz’s doctrine of pre established harmony is supposed to solve?

Overview. Leibniz’s theory is best known as a solution to the mind–body problem of how mind can interact with the body. Leibniz rejected the idea of physical bodies affecting each other, and explained all physical causation in this way.

How did Leibniz attempt to explain the mind body problem?

Formulating (1) through (3) in the language of minds and bodies, Leibniz held that no mental state has as a real cause some state of another created mind or body, and no bodily state has as a real cause some state of another created mind or body.

How many substances are there according to Leibniz?

Leibniz says that there is only one necessary substance, and that this is God. A necessary substance is one whose existence is logically necessary.

What is the theory of Occasionalism?

occasionalism, version of Cartesian metaphysics that flourished in the last half of the 17th century, in which all interaction between mind and body is mediated by God. It is posited that unextended mind and extended body do not interact directly.

Did Leibniz believe in occasionalism?

In other words, Leibniz believed that occasionalism, by claiming that a material object can be put into motion by something other than another material object, namely, the occasional cause of a finite will and the true cause of the divine will, violated a fundamental principle of physics.

What is occasionalism according to Malebranche?

4. Occasionalism. Malebranche is known for his occasionalism, that is, his doctrine that God is the only causal agent, and that creatures merely provide the “occasion” for divine action.
