Reasonings have a natural ordering in God's understanding, but only a temporal order in ours [Leibniz]
|
|
Full Idea:
All reasonings are eminent in God, and they preserve an order among themselves in his understanding as well as in ours; but for him this is just an order and a priority of nature, whereas for us there is a priority of time.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.192), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.III
|
|
A reaction:
This view is found in Frege, and seems to be the hallmark of rationalist philosophy. There is an apriori assumption that reality has a rational order, so that pure reason is a tool for grasping it. Lewis's 'mosaic' of experiences has no order.

Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer]
|
|
Full Idea:
As speakers of the language, we unreflectively assume that there are nonexistents, and that reference to them is possible.
|
|
From:
Marga Reimer (The Problem of Empty Names [2001], p.499), quoted by Sarah Sawyer - Empty Names 4
|
|
A reaction:
Sarah Swoyer quotes this as a good solution to the problem of empty names, and I like it. It introduces a two-tier picture of our understanding of the world, as 'unreflective' and 'reflective', but that seems good. We accept numbers 'unreflectively'.

In all instances of identity, there must be some facts to ensure the identity [Forbes,G]
|
|
Full Idea:
For each instance of identity or failure of identity, there must be facts in virtue of which that instance obtains. ..Enough has been said to lend this doctrine some plausibility.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 5.5)
|
|
A reaction:
Penelope Mackie picks this out from Forbes as a key principle. It sounds to be in danger of circularity, unless the 'facts' can be cited without referring to, or implicitly making use of, identities - which seems unlikely.

If we combined two clocks, it seems that two clocks may have become one clock. [Forbes,G]
|
|
Full Idea:
If we imagine a possible world in which two clocks in a room make one clock from half the parts of each, the judgement 'these two actual clocks could have been a single clock' does not seem wholly false.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 7.4)
|
|
A reaction:
You would, of course, have sufficient parts left over to make a second clock, so they look like a destroyed clock, so I don't think I find Forbes's intuition on this one very persuasive.
|

|
Only individual essences will ground identities across worlds in other properties [Forbes,G, by Mackie,P]
|
|
Full Idea:
Forbes argues that, unless we posit individual essences, we cannot guarantee that identities across possible worlds will be appropriately grounded in other properties.
|
|
From:
report of Graeme Forbes (The Metaphysics of Modality [1985]) by Penelope Mackie - How Things Might Have Been 2.4
|
|
A reaction:
There is a confrontation between Wiggins, who says identity is primitive, and Forbes, who says identity must be grounded in other properties. I think I side with Forbes.
|
12015
|
Non-trivial individual essence is properties other than de dicto, or universal, or relational [Forbes,G]
|
|
Full Idea:
A non-trivial individual essence is properties other than a) those following from a de dicto truth, b) properties of existence and self-identity (or their cognates), c) properties derived from necessities in some other category.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 5.1)
|
|
A reaction:
[I have compressed Forbes] Rather than adding all these qualificational clauses to our concept, we could just tighten up on the notion of a property, saying it is something which is causally efficacious, and hence explanatory.
|
12013
|
Essential properties depend on a category, and perhaps also on particular facts [Forbes,G]
|
|
Full Idea:
The essential properties of a thing will typically depend upon what category of thing it is, and perhaps also on some more particular facts about the thing itself.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 5.1)
|
|
A reaction:
I see no way of dispensing with the second requirement, in the cases of complex entities like animals. If all samples are the same, then of course we can define a sample's essence through its kind, but not if samples differ in any way.
|

An individual might change their sex in a world, but couldn't have differed in sex at origin [Forbes,G]
|
|
Full Idea:
In the time of a single world, the same individual can undergo a change of sex, but it is less clear that an individual of one sex could have been, from the outset, an individual of another.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 6.5)
|
|
A reaction:
I don't find this support for essentiality of origin very persuasive. I struggle with these ideas. Given my sex yesterday, then presumably I couldn't have had a different sex yesterday. Given that pigs can fly, pigs can fly. What am I missing?
|
11888
|
Identities must hold because of other facts, which must be instrinsic [Forbes,G, by Mackie,P]
|
|
Full Idea:
Forbes has two principles of identity, which we can call the No Bare Identities Principle (identities hold in virtue of other facts), and the No Extrinsic Determination Principle (that only intrinsic facts of a thing establish identity).
|
|
From:
report of Graeme Forbes (The Metaphysics of Modality [1985], 127-8) by Penelope Mackie - How Things Might Have Been 2.7
|
|
A reaction:
The job of the philosopher is to prise apart the real identities of things from the way in which we conceive of identities. I take these principles to apply to real identities, not conceptual identities.
|
12008
|
Unlike places and times, we cannot separate possible worlds from what is true at them [Forbes,G]
|
|
Full Idea:
There is no means by which we might distinguish a possible world from what is true at it. ...Whereas our ability to separate a place, or a time, from its occupier is crucial to realism about places and times, as is a distance relation.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 4.2)
|
|
A reaction:
He is objecting to Lewis's modal realism. I'm not fully convinced. It depends whether we are discussing real ontology or conceptual space. In the latter I see no difference between times and possible worlds. In ontology, a 'time' is weird.
|
12016
|
The problem of transworld identity can be solved by individual essences [Forbes,G]
|
|
Full Idea:
The motivation for investigating individual essences should be obvious, since if every object has such an essence, the problem of elucidating transworld identity can be solved.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 5.1)
|
|
A reaction:
It is important that, if necessary, the identities be 'individual', and not just generic, by sortal, or natural kind. We want to reason about (and explain) truths at the fine-grained level of the individual, not just at the broad level of generalisation.
|
12029
|
We believe in thisnesses, because we reject bizarre possibilities as not being about that individual [Forbes,G]
|
|
Full Idea:
The natural response to an unreasonable hypothesis of possibility for an object x, that in such a state of affairs it would not be x which satisfies the conditions, is evidence that we do possess concepts of thisness for individuals.
|
|
From:
Graeme Forbes (The Metaphysics of Modality [1985], 9.4)
|
|
A reaction:
We may have a 'concept' of thisness, but we needn't be committed to the 'existence' of a thisness. There is a fairly universal intuition that cessation of existence of an entity when it starts to change can be a very vague matter.
|
19367
|
Saying we must will whatever we decide to will leads to an infinite regress [Leibniz]
|
|
Full Idea:
As for volition itself, to say that it is the object of free will is incorrect. We will to act, strictly speaking, and we do not will to will, else we should still say we will to have the will to will, and that would go on to infinity.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.151), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 4.IV
|
|
A reaction:
This strikes me as an elementary difficulty which most fans of free will appear to evade. Thoughts just arise in us, and some of them are volitions. We can say there is then a 'gap' (Searle) where we choose, but what happens in the gap?
|
19351
|
Perfections of soul subordinate the body, but imperfections of soul submit to the body [Leibniz]
|
|
Full Idea:
Insofar as the soul has perfection ...God has accommodated the body to the soul, and has arranged beforehand that the body is impelled to execute its orders. Insofar as it is imperfect and confused, God accommodates soul to body, swayed by passions.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.159), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 3.IV
|
|
A reaction:
Perkins says this is the nearest Leibniz gets to the idea of interaction between body and soul. Perfection and confusion are on a continuum for Leibniz. With such speculations I always wonder how these things can be known. How perfect is my mind?
|
19346
|
Most people facing death would happily re-live a similar life, with just a bit of variety [Leibniz]
|
|
Full Idea:
I believe there would be few persons who, being at the point of death, were not content to take up life again, on condition of passing through the same amount of good and evil, provided that it were not the same kind.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.130), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
|
|
A reaction:
Nice challenge. People who refuse the offer are not necessarily suicidal. He's probably right, but Leibniz doesn't recognise the factor of boredom. Look up the suicide note of the actor George Sanders! One life may be enough.
|

|
Metaphysical evil is imperfection; physical evil is suffering; moral evil is sin [Leibniz]
|
|
Full Idea:
Evil may be taken metaphysically, physically, and morally. Metaphysical evil consists in mere imperfection, physical evil is suffering, and moral evil is sin.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.136), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
|
|
A reaction:
There seem to be plenty of imperfections in the world which don't look like evil. Or do you only declare it to be an imperfection because it seems to be evil (by some other standard)? Human evil comes from ignorance, so metaphysical explains moral.
|
19327
|
The intelligent cause must be unique and all-perfect, to handle all the interconnected possibilities [Leibniz]
|
|
Full Idea:
The intelligent cause ought to be infinite in all ways, and absolutely perfect in power, in wisdom, and in goodness, since it relates to all that which is possible. Also, since all is connected together, there is no ground for admitting more than one.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.128), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
|
|
A reaction:
Notice that Leibniz's possible worlds seem to be all connected together, unlike David Lewis's worlds, which are discrete. Personally I suspect that all perfections will lead to contradiction, though Leibniz strongly argues against it.
|
19330
|
If justice is arbitrary, or fixed but not observed, or not human justice, this undermines God [Leibniz]
|
|
Full Idea:
The three dogmas (1) that the nature of justice is arbitrary, (2) it is fixed, but not certain God will observe it, or (3) the justice we know is not that which God observes, destroy our confidence in the love of God.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.237), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.III
|
|
A reaction:
Leibniz proceeds to carefully refute these three responses to the dilemma about how justice relates to God.
|
19329
|
The laws of physics are wonderful evidence of an intelligent and free being [Leibniz]
|
|
Full Idea:
These admirable laws [of physics] are wonderful evidence of an intelligent and free being, as opposed to the system of absolute and brute necessity, advocated by Strato and Spinoza.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.332), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
|
|
A reaction:
Note the swipe at Spinoza. Leibniz defends the absolute necessities residing in God, but is too polite to call those 'brute', though personally I can't see the difference. But he says the laws arise from 'perfection and order', not from God's necessity.
|
19337
|
How can an all-good, wise and powerful being allow evil, sin and apparent injustice? [Leibniz]
|
|
Full Idea:
There is this question of natural theology, how a sole Principle, all-good, all-wise and all-powerful, has been able to admit evil, and especially to permit sin, and how it could resolve to make the wicked often happy and the good unhappy?
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.098), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
|
|
A reaction:
His answer is, roughly, that there is an unavoidable trade-off, which humans cannot fully understand. Personally I would say that if there is a God, the evidence for his benevolence towards humanity is not encouraging.
|
19345
|
Being confident of God's goodness, we disregard the apparent local evils in the visible world [Leibniz]
|
|
Full Idea:
Being made confident by demonstrations of the goodness and the justice of God, we disregard the appearances of harshness and justice which we see in this small portion of his Kingdom that is exposed to our gaze.
|
|
From:
Gottfried Leibniz (The Theodicy [1710], p.120), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
|
|
A reaction:
Hm. If this locality is full of evils, and the rest of it is much better, how come we are stuck in this miserable corner of things? God is obliged to compromise, but did he select us to get the worst of it?
