2. Reason / A. Nature of Reason / 1. On Reason
When questions are doubtful we should concentrate not on objects but on ideas of the intellect [Plato]
     Full Idea: Doubtful questions should not be discussed in terms of visible objects or in relation to them, but only with reference to ideas conceived by the intellect.
     From: Plato (Parmenides [c.364 BCE], 135e)
2. Reason / B. Laws of Thought / 5. Opposites
Opposites are as unlike as possible [Plato]
     Full Idea: Opposites are as unlike as possible.
     From: Plato (Parmenides [c.364 BCE], 159a)
2. Reason / C. Styles of Reason / 1. Dialectic
Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic [Hegel on Plato]
     Full Idea: Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic.
     From: comment on Plato (Parmenides [c.364 BCE]) by Georg W.F.Hegel - Phenomenology of Spirit Pref 71
     A reaction: It is a long way from the analytic tradition of philosophy to be singling out a classic text for its 'artistic' achievement. Eventually we may even look back on, say, Kripke's 'Naming and Necessity' and see it in that light.
5. Theory of Logic / L. Paradox / 3. Antinomies
Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle]
     Full Idea: Plato (in 'Parmenides') shows that the theory that 'Eide' are substances, and Kant that space and time are substances, and Bradley that relations are substances, all lead to aninomies.
     From: report of Plato (Parmenides [c.364 BCE]) by Gilbert Ryle - Are there propositions? 'Objections'
Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato]
     Full Idea: Plato's 'Parmenides' is perhaps the best collection of antinomies ever made.
     From: comment on Plato (Parmenides [c.364 BCE]) by Bertrand Russell - The Principles of Mathematics §337
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / a. For mathematical platonism
One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato]
     Full Idea: If one is, there must also necessarily be number - Necessarily - But if there is number, there would be many, and an unlimited multitude of beings. ..So if all partakes of being, each part of number would also partake of it.
     From: Plato (Parmenides [c.364 BCE], 144a)
     A reaction: This seems to commit to numbers having being, then to too many numbers, and hence to too much being - but without backing down and wondering whether numbers had being after all. Aristotle disagreed.
7. Existence / A. Nature of Existence / 3. Being / c. Becoming
The one was and is and will be and was becoming and is becoming and will become [Plato]
     Full Idea: The one was and is and will be and was becoming and is becoming and will become.
     From: Plato (Parmenides [c.364 BCE], 155d)
7. Existence / A. Nature of Existence / 3. Being / f. Primary being
Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus]
     Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many.
     From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08
     A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God.
7. Existence / A. Nature of Existence / 5. Reason for Existence
I do not believe in the existence of anything, if I see no reason to believe it [Berkeley]
     Full Idea: It is to me a sufficient reason not to believe the existence of anything, if I see no reason for believing it.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.205)
     A reaction: This may just be a reasonable application of Ockham's Razor, but I fear that Berkeley painted himself into corner by demanding too many 'reasons' for everything.
7. Existence / A. Nature of Existence / 6. Criterion for Existence
I know that nothing inconsistent can exist [Berkeley]
     Full Idea: I know that nothing inconsistent can exist.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.224)
     A reaction: Fine, but the problem is to assess with confidence what is inconsistent. Human imagination seems to be the test for existence. But what else can we do?
7. Existence / B. Change in Existence / 1. Nature of Change
You can't deny temporary intrinsic properties by saying the properties are relations (to times) [Lewis]
     Full Idea: To say that properties are really relations to times is to treat temporary intrinsics (such as my changing shape) as a matter of relations, but then 'intrinsic properties' would not deserve the name, and it is untenable if it denies temporary intrinsics.
     From: David Lewis (Rearrangement of Particles [1988], 1)
     A reaction: [I have compressed a paragraph; he refers to his 1986:204] If a property is meant to be a 'relation to a time', I am not sure what the relata are meant to be, and I agree with Lewis that this seems a long way from properties.
7. Existence / D. Theories of Reality / 3. Reality
Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato]
     Full Idea: The absolute good and the beautiful and all which we conceive to be absolute ideas are unknown to us.
     From: Plato (Parmenides [c.364 BCE], 134c)
8. Modes of Existence / D. Universals / 2. Need for Universals
You must always mean the same thing when you utter the same name [Plato]
     Full Idea: You must always mean the same thing when you utter the same name.
     From: Plato (Parmenides [c.364 BCE], 147d)
If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato]
     Full Idea: If a person denies that the idea of each thing is always the same, he will utterly destroy the power of carrying on discussion.
     From: Plato (Parmenides [c.364 BCE], 135c)
8. Modes of Existence / D. Universals / 6. Platonic Forms / a. Platonic Forms
It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato]
     Full Idea: Are there abstract ideas for such things as hair, mud and dirt, which are particularly vile and worthless? That would be quite absurd.
     From: Plato (Parmenides [c.364 BCE], 130d)
The concept of a master includes the concept of a slave [Plato]
     Full Idea: Mastership in the abstract is mastership of slavery in the abstract.
     From: Plato (Parmenides [c.364 BCE], 133e)
If admirable things have Forms, maybe everything else does as well [Plato]
     Full Idea: It is troubling that if admirable things have abstract ideas, then perhaps everything else must have ideas as well.
     From: Plato (Parmenides [c.364 BCE], 130d)
If absolute ideas existed in us, they would cease to be absolute [Plato]
     Full Idea: None of the absolute ideas exists in us, because then it would no longer be absolute.
     From: Plato (Parmenides [c.364 BCE], 133c)
Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato]
     Full Idea: These two ideas, greatness and smallness, exist, do they not? For if they did not exist, they could not be opposites of one another, and could not come into being in things.
     From: Plato (Parmenides [c.364 BCE], 149e)
Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M]
     Full Idea: It seems to me that Plato in the later dialogues, beginning with the second half of 'Parmenides', wants to substitute a theory of genera and theory of principles that constitute these genera for the earlier theory of forms.
     From: report of Plato (Parmenides [c.364 BCE]) by Michael Frede - Title, Unity, Authenticity of the 'Categories' V
     A reaction: My theory is that the later Plato came under the influence of the brilliant young Aristotle, and this idea is a symptom of it. The theory of 'principles' sounds like hylomorphism to me.
8. Modes of Existence / D. Universals / 6. Platonic Forms / b. Partaking
Participation is not by means of similarity, so we are looking for some other method of participation [Plato]
     Full Idea: Participation is not by means of likeness, so we must seek some other method of participation.
     From: Plato (Parmenides [c.364 BCE], 133a)
The whole idea of each Form must be found in each thing which participates in it [Plato]
     Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it.
     From: Plato (Parmenides [c.364 BCE], 131a)
Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato]
     Full Idea: Just as day is in many places at once, but not separated from itself, so each idea might be in all its participants at once.
     From: Plato (Parmenides [c.364 BCE], 131b)
If things are made alike by participating in something, that thing will be the absolute idea [Plato]
     Full Idea: That by participation in which like things are made like, will be the absolute idea, will it not?
     From: Plato (Parmenides [c.364 BCE], 132e)
If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato]
     Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think?
     From: Plato (Parmenides [c.364 BCE], 132c)
8. Modes of Existence / D. Universals / 6. Platonic Forms / c. Self-predication
Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato]
     Full Idea: It is impossible for anything to be like an absolute idea, because a third idea will appear to make them alike, and if that is like anything, it will lead to another idea, and so on.
     From: Plato (Parmenides [c.364 BCE], 133a)
If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato]
     Full Idea: If you regard the absolute great and the many great things in the same way, will not another appear beyond, by which all these must appear to be great?
     From: Plato (Parmenides [c.364 BCE], 132a)
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Parts must belong to a created thing with a distinct form [Plato]
     Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all.
     From: Plato (Parmenides [c.364 BCE], 157d)
     A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism.
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
There is no other substance, in a strict sense, than spirit [Berkeley]
     Full Idea: There is no other substance, in a strict sense, than spirit.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.257)
     A reaction: A nice clear statement of idealism. Why is he so confident of making this assertion. Note the addition, though, of 'in a strict' sense. He is presenting an epistemological claim as if it was an ontological one.
9. Objects / C. Structure of Objects / 5. Composition of an Object
In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V]
     Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts
     From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5
     A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something?
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
Plato says only a one has parts, and a many does not [Plato, by Harte,V]
     Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one.
     From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2
     A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships.
Anything which has parts must be one thing, and parts are of a one, not of a many [Plato]
     Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole.
     From: Plato (Parmenides [c.364 BCE], 157c)
     A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
It seems that the One must be composed of parts, which contradicts its being one [Plato]
     Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts.
     From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2
     A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts.
9. Objects / F. Identity among Objects / 6. Identity between Objects
Two things relate either as same or different, or part of a whole, or the whole of the part [Plato]
     Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part.
     From: Plato (Parmenides [c.364 BCE], 146b)
     A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically.
10. Modality / A. Necessity / 10. Impossibility
A thing is shown to be impossible if a contradiction is demonstrated within its definition [Berkeley]
     Full Idea: A thing is shown to be impossible when a repugnancy is demonstrated between the ideas comprehended in its definition.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.214)
     A reaction: The problem is always that imagination is needed to see the 'repugnancy', and that is relative and limited.
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / a. Naïve realism
Since our ideas vary when the real things are said to be unchanged, they cannot be true copies [Berkeley]
     Full Idea: As our ideas are perpetually varied, without any change in the supposed real things, it necessarily follows that they cannot all be true copies of them.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.239)
     A reaction: This seems a good objection to any direct or naïve realist view. Colours get darker as the sun goes down, and objects become blurred as they recede into the distance.
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / b. Direct realism
If existence is perceived directly, by which sense; if indirectly, how is it inferred from direct perception? [Berkeley]
     Full Idea: Either you perceive the being of matter immediately, or mediately; if immediately, pray inform me by which of the senses you perceive it; if mediately, let me know by what reasonings it is inferred from those things which you perceive immediately.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.208)
     A reaction: A problem for strong empiricists, and he is right that existence can't be directly perceived, but it seems a good explanation (for which some reason can be shown), and supports a more rationalist view.
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Sensible objects are just sets of sensible qualities [Berkeley]
     Full Idea: Sensible things are nothing else but so many sensible qualities.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.154)
     A reaction: As it stands this is phenomenalism, but Berkeley eventually votes for idealism. He should acknowledge possible sensations which aren't actually experienced.
Berkeley did not deny material things; he merely said they must be defined through sensations [Berkeley, by Ayer]
     Full Idea: Berkeley did not (as we are commonly told) deny the reality of material things. ..What Berkeley discovered was that material things must be defined in terms of sense-contents.
     From: report of George Berkeley (Three Dialogues of Hylas and Philonous [1713]) by A.J. Ayer - Language,Truth and Logic Ch.2
     A reaction: This seems to be a rather debatable attempt to claim that Berkeley was a phenomenalist (like Ayer), rather than an idealist. Try ideas 3942, 3944, 3945, 3957, 3959 in this database.
Berkeley needed a phenomenalist account of the self, as well as of material things [Ayer on Berkeley]
     Full Idea: The considerations which make it necessary, as Berkeley saw, to give a phenomenalist account of material things, make it necessary also, as Berkeley did not see, to give a phenomenalist account of the self.
     From: comment on George Berkeley (Three Dialogues of Hylas and Philonous [1713]) by A.J. Ayer - Language,Truth and Logic Ch.7
     A reaction: Phenomenalism involves 'possible' experiences as well as actual ones. That could add up to quite a rich and stable account of the self, as opposed to Hume's notorious introspection, which only saw an actual shifting 'bundle' of experience.
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / c. Empirical idealism
'To be is to be perceived' is a simple confusion of experience with its objects [Russell on Berkeley]
     Full Idea: Berkeley thinks 'to be is to be perceived', and only God provides continuity. He has simply confused the experience of perception with the thing being perceived. Ideas have content.
     From: comment on George Berkeley (Three Dialogues of Hylas and Philonous [1713]) by Bertrand Russell - Problems of Philosophy
For Berkelely, reality is ideas and a community of minds, including God's [Berkeley, by Grayling]
     Full Idea: Berkeley's thesis is that reality ultimately consists of a community of minds and their ideas; one of the minds (God) is infinite, and causes most of the ideas.
     From: report of George Berkeley (Three Dialogues of Hylas and Philonous [1713]) by A.C. Grayling - Russell Ch.2
     A reaction: I think Russell nicely pinpoints what is wrong with Berekely, which is that he confuses ideas with their contents. If I think about my garden, the garden is real (probably), which is the content, and they idea is just a way of thinking.
Time is measured by the succession of ideas in our minds [Berkeley]
     Full Idea: Time is measured by the succession of ideas in our minds.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.172)
     A reaction: But we distinguish between subjective time (which flies when you are having fun), and objective time, judged from observation of clocks and nature.
There is no such thing as 'material substance' [Berkeley]
     Full Idea: That there is no such thing as what philosophers call 'material substance', I am seriously persuaded.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.150)
     A reaction: I'm sorry, but I can't do with this. It confuses epistemology with ontology. Ontology is a matter of judgement; epistemology is the evidence on which we base it. We know sensations; personally I judge that there are material substances. What about you?
I conceive a tree in my mind, but I cannot prove that its existence can be conceived outside a mind [Berkeley]
     Full Idea: I may conceive in my own thoughts the idea of a tree, but that is all. And this is far from proving that I can conceive it existing out of the minds of all spirits.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.184)
     A reaction: If Berkeley has based a world view on this point, then his mistake is to require a 'proof'. Aristotle explained why you can't prove everything (not to mention Gödel).
There is nothing in nature which needs the concept of matter to explain it [Berkeley]
     Full Idea: I challenge you to show me that thing in nature which needs matter to explain or account for it.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.212)
     A reaction: I disagree. Physics is a good theory for explaining why we have perceptions. Failing that there is not even a glimmer of an explanation of our experiences.
Perceptions are ideas, and ideas exist in the mind, so objects only exist in the mind [Berkeley]
     Full Idea: Wood, fire, water, flesh, iron, are things that I know, and only known because I perceive them by my senses; these are immediately perceived, and so are ideas; ideas cannot exist without the mind; their existence consists therefore in being perceived.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.220)
     A reaction: This makes no distinction between an idea and its content. Berkeley fails to grasp the weird concept of intentionality. Trees aren't in my head, just because I think about them!
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / c. Primary qualities
Primary qualities (such as shape, solidity, mass) are held to really exist, unlike secondary qualities [Berkeley]
     Full Idea: Sensible qualities are by philosophers divided into primary and secondary; the former are extension, figure, solidity, gravity, motion and rest, which exist really in bodies.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.169)
     A reaction: A crucial distinction, which anti-realists such as Berkeley end up denying. I think it is a good distinction, and philosophers should fight to preserve it.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
A mite would see its own foot as large, though we would see it as tiny [Berkeley]
     Full Idea: A mite must be supposed to see his own foot as a body of some considerable dimension, though they appear to you scarcely discernible.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.170)
     A reaction: Berkeley is confused. Hot is secondary, but temperature is primary. Bigness is secondary, size primay. Midgets and tall people don't disagree over the size of a table.
The apparent size of an object varies with its distance away, so that can't be a property of the object [Berkeley]
     Full Idea: As we approach to or recede from an object, the visible extension varies, being at one distance ten or a hundred times greater than at another; doth it not follow that it is not really inherent in the object?
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.171)
     A reaction: Berkeley is confused, because he is too literally empirical. Qualities are not self-evidently primary or secondary, but are judged so after comparisons (e.g. with testimony, or with the other senses).
'Solidity' is either not a sensible quality at all, or it is clearly relative to our senses [Berkeley]
     Full Idea: By 'solidity' either you do not mean any sensible quality, and so it is beside our enquiry; or if you do, it must be hardness or resistance, which are plainly relative to our senses.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.173)
     A reaction: Berkeley fails to recognise that a quality can have primary and secondary aspects (hot/high temperature). He is right that primary qualities are not directly perceived. They are judgements.
Distance is not directly perceived by sight [Berkeley]
     Full Idea: Distance is not properly and immediately perceived by sight.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.186)
     A reaction: Interestingly, if secondary qualities are not strictly perceptions of the object, and primary qualities are not directly perceived, then we don't seem to perceive anything at all. Perhaps we should drop the concept of 'perception'?
12. Knowledge Sources / B. Perception / 3. Representation
Immediate objects of perception, which some treat as appearances, I treat as the real things themselves [Berkeley]
     Full Idea: Those immediate objects of perception, which, according to you, are only appearances of things, I take to be the real things themselves.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.237)
     A reaction: If that is a judgement, which it seems to be, it is a strange one. Realists offer a much better explanation of perceptions.
12. Knowledge Sources / D. Empiricism / 1. Empiricism
Real things and imaginary or dreamed things differ because the latter are much fainter [Berkeley]
     Full Idea: The difference between real things, and chimeras formed by the imagination, or the visions of a dream, is that the latter are faint and indistinct.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.225)
     A reaction: In Hume this becomes 'impressions' and 'ideas'. It does raise the question of WHY some ideas are not as faint as others.
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
Geometry is originally perceived by senses, and so is not purely intellectual [Berkeley]
     Full Idea: Figures and extension, being originally perceived by sense, do not belong to pure intellect.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.176)
     A reaction: Is the square root of 169 less 'pure' in my mind if I learn it from laying out bricks instead of by thinking about numbers? Confusion of how you learn with what you learn?
13. Knowledge Criteria / D. Scepticism / 3. Illusion Scepticism
It is possible that we could perceive everything as we do now, but nothing actually existed. [Berkeley]
     Full Idea: We might perceive all things just as we do now, though there was no matter in the world.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.209)
     A reaction: An old Greek argument. Now we have an explanation of experience, but we wouldn't if nothing existed. Which doesn't prove that anything exists. Is some explanation always preferable to none? Cf. religion.
13. Knowledge Criteria / E. Relativism / 3. Subjectivism
A hot hand and a cold hand will have different experiences in the same tepid water [Berkeley]
     Full Idea: Suppose now one of your hands hot, and the other cold, and that they are both at once put into the same vessel of water, in an intermediate state; will not the water seem cold to one hand, and warm to the other?
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], I p.158)
     A reaction: A nice clear example of how some relativism must be acknowledged. It feels hot, but what is its temperature in degrees C?
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
Experience tells me that other minds exist independently from my own [Berkeley]
     Full Idea: It is plain that other minds have an existence exterior to my mind, since I find them by experience to be independent of it.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.220)
     A reaction: This is a surprising claim from Berkeley. If trees only exist through their experience in my mind, why don't other minds exist in the same way?
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
How can that which is unthinking be a cause of thought? [Berkeley]
     Full Idea: How can that which is unthinking be a cause of thought?
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.203)
     A reaction: Presumably, though, he thinks that thought can cause 'that which is unthinking' to move'. He likes one half of the interaction problem (which supports dualism), but avoids the other half.
18. Thought / C. Content / 2. Ideas
Berkeley probably used 'idea' to mean both the act of apprehension and the thing apprehended [Russell on Berkeley]
     Full Idea: Berkeley seems to have confused the colour of the thing apprehended with the act of apprehension; probably either of these would have been called an 'idea' be Berkeley.
     From: comment on George Berkeley (Three Dialogues of Hylas and Philonous [1713]) by Bertrand Russell - Problems of Philosophy
     A reaction: If we are saying that Berkeley's error was entirely verbal, there is a chicken-and-egg problem. He was an idealist, so he wouldn't have thought that there were two separate concepts behind the word 'idea'. Russell merely asserts that there are.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / a. Preconditions for ethics
Immorality is not in the action, but in the deviation of the will from moral law [Berkeley]
     Full Idea: Sin or moral turpitude doth not consist in the outward physical action or motion, but in the internal deviation of the will from the laws of reason and religion.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.227)
     A reaction: A Kantian view (that the only good thing is a good will). It is a very empiricist (and anti-Greek) view to deny that actions have any intrinsic value.
25. Social Practice / E. Policies / 5. Education / c. Teaching
Only a great person can understand the essence of things, and an even greater person can teach it [Plato]
     Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this.
     From: Plato (Parmenides [c.364 BCE], 135a)
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / d. The unlimited
The unlimited has no shape and is endless [Plato]
     Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges.
     From: Plato (Parmenides [c.364 BCE], 137e)
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / e. The One
Some things do not partake of the One [Plato]
     Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole.
     From: Plato (Parmenides [c.364 BCE], 159d)
     A reaction: Compare Idea 231
The only movement possible for the One is in space or in alteration [Plato]
     Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions.
     From: Plato (Parmenides [c.364 BCE], 138b)
Everything partakes of the One in some way [Plato]
     Full Idea: The others are not altogether deprived of the one, for they partake of it in some way.
     From: Plato (Parmenides [c.364 BCE], 157c)
     A reaction: Compare Idea 233.
28. God / B. Proving God / 1. Proof of God
There must be a God, because I and my ideas are not independent [Berkeley]
     Full Idea: From the dependency I find in myself and my ideas, I do by an act of reason necessarily infer the existence of a God.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.222)
     A reaction: No. Hume answered this, by showing how big abstract ideas are built up from experience. This is a future bishop's wish-fulfilment.
There must be a God, because all sensible things must be perceived by him [Berkeley]
     Full Idea: I immediately and necessarily conclude the being of a God, because all sensible things must be perceived by him.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.198)
     A reaction: Daft. This contradicts Berkeley's whole empiricist position, that existence depends on known experience. Who knows whether God is thinking about trees?
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
We couldn't discuss the non-existence of the One without knowledge of it [Plato]
     Full Idea: There must be knowledge of the one, or else not even the meaning of the words 'if the one does not exist' would be known.
     From: Plato (Parmenides [c.364 BCE], 160d)
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
It has been proved that creation is the workmanship of God, from its beauty and usefulness [Berkeley]
     Full Idea: Divines and philosophers have proved beyond all controversy, from the beauty and usefulness of the several parts of creation, that it was the workmanship of God.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.198)
     A reaction: Not convincing. Beauty is probably a sublimation of sexual desire (or an echo of the human mind in the external world, in music), and utility is relative to homo sapiens, I presume.
29. Religion / D. Religious Issues / 3. Problem of Evil / b. Human Evil
People are responsible because they have limited power, though this ultimately derives from God [Berkeley]
     Full Idea: Thinking rational beings, in the production of motions, have the use of limited powers, ultimately derived from God, but immediately under the direction of their own wills, which is sufficient to entitle them to all the guilt of their own actions.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.228)
     A reaction: An episcopal evasion. A classic attempt to have cake and eat it. Either God is in charge or he isn't.
29. Religion / D. Religious Issues / 3. Problem of Evil / d. Natural Evil
If sin is not just physical, we don't consider God the origin of sin because he causes physical events [Berkeley]
     Full Idea: If sin doth not consist of purely physical actions, the making God a cause of all such actions, is not making him the author of sin.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.227)
     A reaction: An equivocation. If responsibility resides in consciousness, God is presumably conscious, and we can judge the events he causes.
