57 ideas

1. Philosophy / A. Wisdom / 1. Nature of Wisdom
A sense of timelessness is essential to wisdom [Russell]
     Full Idea: Both in thought and in feeling, to realize the unimportance of time is the gate of wisdom.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 6)
     A reaction: A very rationalist and un-Heraclitean view of wisdom. This picture may give wisdom a bad name, if wise people are (at a minimum) at least expected to give good advice about real life.
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
Philosophical disputes are mostly hopeless, because philosophers don't understand each other [Russell]
     Full Idea: Explicit controversy is almost always fruitless in philosophy, owing to the fact that no two philosophers ever understand one another.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 1)
     A reaction: Contemporaries don't even seem to read one another very much, especially these days, when there are thousands of professional philosophers. (If you are a professional, have you read all the works written by your colleagues and friends?)
1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
Philosophical systems are interesting, but we now need a more objective scientific philosophy [Russell]
     Full Idea: The great systems of the past serve a very useful purpose, and are abundantly worthy of study. But something different is required if philosophy is to become a science, and to aim at results independent of the tastes of the philosophers who advocate them.
     From: Bertrand Russell (Our Knowledge of the External World [1914], Pref)
     A reaction: An interesting product of this move in philosophy is (about sixty years later) the work of David Lewis, who set out to be precise and scientific, and ended up creating a very personal system. Why not a collaborative system?
Hegel's confusions over 'is' show how vast systems can be built on simple errors [Russell]
     Full Idea: Hegel's confusion of the 'is' of predication with the 'is' of identity ...is an example of how, for want of care at the start, vast and imposing systems of philosophy are built upon stupid and trivial confusions.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 2 n1)
     A reaction: [He explains the confusion in more detail in the note] Russell cites an English translation, and I am wondering how this occurs in the German. Plato has been accused of similar elementary blunders about properties. Russell treats Berkeley similarly.
Philosophers sometimes neglect truth and distort facts to attain a nice system [Russell]
     Full Idea: The desire for unadulterated truth is often obscured, in professional philosophers, by love of system: the one little fact which will not come inside the philosophical edifice has to be pushed and tortured until it seems to consent.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 8)
     A reaction: Bit of hypocrisy here. Russell was continually trying to find a system, grounded in physics and logic. Presumably his shifting views are indications of integrity, because he changes the system rather than the facts.
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Physicists accept particles, points and instants, while pretending they don't do metaphysics [Russell]
     Full Idea: Physicists, ignorant and contemptuous of philosophy, have been content to assume their particles, points and instants in practice, while contending, with ironical politeness, that their concepts laid no claim to metaphysical validity.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 4)
     A reaction: Presumably physicists are allowed to wave their hands and utter the word 'instrumentalism', and then get on with the job. They just have to ensure they never speculate about what is being measured.
1. Philosophy / F. Analytic Philosophy / 6. Logical Analysis
When problems are analysed properly, they are either logical, or not philosophical at all [Russell]
     Full Idea: Every philosophical problem, when it is subjected to the necessary analysis and purification, is found either to be not really philosophical at all, or else to be, in the sense in which we are using the word, logical.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 2)
     A reaction: [All Lecture 2 discusses 'logical'] I think Bertie was getting carried away here. In his life's corpus he barely acknowledges the existence of ethics, or political philosophy, or aesthetics. He never even engages with 'objects' the way Aristotle does.
5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
Logic gives the method of research in philosophy [Russell]
     Full Idea: Logic gives the method of research in philosophy, just as mathematics gives the method in physics.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 8)
     A reaction: I'm struck by how rarely philosophers actually prove anything. Mostly they just use the language of logic as a tool for disambiguation. Only a tiny handful of philosophers can actually create sustained and novel proofs.
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
The logical connectives are not objects, but are formal, and need a context [Russell]
     Full Idea: Such words as 'or' and 'not' are not names of definite objects, but are words that require a context in order to have a meaning. All of them are formal.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 7)
     A reaction: [He cites Wittgenstein's 1922 Tractatus in a footnote - presumably in a later edition than 1914] This is the most famous idea which Russell acquired from Wittgenstein. It was yet another step in his scaling down of ontology.
5. Theory of Logic / K. Features of Logics / 7. Decidability
Validity is provable, but invalidity isn't, because the model is infinite [Church, by McGee]
     Full Idea: Church showed that logic has a proof procedure, but no decision procedure. If an argument is invalid, there is a model with true premises and false conclusion, but the model will typically be infinite, so there is no way to display it concretely.
     From: report of Alonzo Church (A Note on the entscheidungsproblem [1936]) by Vann McGee - Logical Consequence 5
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox
The tortoise won't win, because infinite instants don't compose an infinitely long time [Russell]
     Full Idea: The idea that an infinite number of instants make up an infinitely long time is not true, and therefore the conclusion that Achilles will never overtake the tortoise does not follow.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 6)
     A reaction: Aristotle spotted this, but didn't express it as clearly as Russell.
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 / C. Structure of Existence / 6. Fundamentals / d. Logical atoms
Atomic facts may be inferrable from others, but never from non-atomic facts [Russell]
     Full Idea: Perhaps one atomic fact may sometimes be capable of being inferred from another, though I do not believe this to be the case; but in any case it cannot be inferred from premises no one of which is an atomic fact.
     From: Bertrand Russell (Our Knowledge of the External World [1914], p.48)
     A reaction: I prefer Russell's caution to Wittgenstein's dogmatism. I presume utterly simple facts give you nothing to work with. Hegel thought that you could infer new concepts from given concepts.
7. Existence / D. Theories of Reality / 8. Facts / d. Negative facts
A positive and negative fact have the same constituents; their difference is primitive [Russell]
     Full Idea: It must not be supposed that a negative fact contains a constituent corresponding to the word 'not'. It contains no more constituents than a positive fact of the correlative positive form. The differenece between the two forms is ultimate and irreducible.
     From: Bertrand Russell (Our Knowledge of the External World [1914], VIII.279), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 41 'Neg'
     A reaction: ['Harvard Lectures'] The audience disliked this. How does one fact exclude the other fact? Potter asks whether absence is a fact, and whether an absence can be a truthmaker.
8. Modes of Existence / A. Relations / 1. Nature of Relations
With asymmetrical relations (before/after) the reduction to properties is impossible [Russell]
     Full Idea: When we come to asymmetrical relations, such as before and after, greater and less etc., the attempt to reduce them to properties becomes obviously impossible.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 2)
     A reaction: The traditional Aristotelian reduction to properties is attributed by Russell to logic based on subject-predicate. As an example he cites being greater than as depending on more than the mere magnitudes of the entities. Direction of the relation.
8. Modes of Existence / B. Properties / 11. Properties as Sets
When we attribute a common quality to a group, we can forget the quality and just talk of the group [Russell]
     Full Idea: When a group of objects have the similarity we are inclined to attribute to possession of a common quality, the membership of the group will serve all the purposes of the supposed common quality ...which need not be assumed to exist.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 2)
     A reaction: This is the earliest account I have found of properties being treated as sets of objects. It more or less coincides with the invention of set theory. I am reminded of Idea 9208. What is the bazzing property? It's what those three things have in common.
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.
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 / 1. Perceptual Realism / c. Representative realism
Science condemns sense-data and accepts matter, but a logical construction must link them [Russell]
     Full Idea: Men of science condemn immediate data as 'merely subjective', while maintaining the truths of physics from those data. ...The only justification possible for this must be one which exhibits matter as a logical construction from sense-data.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 4)
     A reaction: Since we blatantly aren't doing logic when we stare out of the window, this aspires to finding something like the 'logical form' of perception.
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 / B. Perception / 4. Sense Data / c. Unperceived sense-data
When sense-data change, there must be indistinguishable sense-data in the process [Russell]
     Full Idea: In all cases of sense-data capable of gradual change, we may find one sense-datum indistinguishable from another, and that indistinguishable from a third, while yet the first and third are quite easily distinguishable.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 5)
     A reaction: This point is key to the sense-data theory, because it gives them independent existence, standing between reality and subjective experience. It is also the reason why they look increasingly implausible, if they may not be experienced.
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Empirical truths are particular, so general truths need an a priori input of generality [Russell]
     Full Idea: All empirical evidence is of particular truths. Hence, if there is any knowledge of general truths at all, there must be some knowledge of general truths which is independent of empirical evidence.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 2)
     A reaction: Humean empiricists respond by being a sceptical of general truths. At this stage of his career Russell looks like a thoroughgoing rationalist, and he believes in the reality of universals, relations and propositions. He became more empirical later.
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 / B. Internal Justification / 5. Coherentism / b. Pro-coherentism
Objects are treated as real when they connect with other experiences in a normal way [Russell]
     Full Idea: Objects of sense are called 'real' when they have the kind of connection with other objects of sense which experience has led us to regard as normal; when they fail this, they are called 'illusions'.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 3)
     A reaction: This rests rather too much on the concept of 'normal', but offers an attractive coherence account of perception. Direct perceptions are often invoked by anti-coherentists, but I think coherence is just as much needed in that realm.
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 / D. Scepticism / 6. Scepticism Critique
Global scepticism is irrefutable, but can't replace our other beliefs, and just makes us hesitate [Russell]
     Full Idea: Universal scepticism, though logically irrefutable, is practically barren; it can only, therefore, give a certain flavour of hesitancy to our beliefs, and cannot be used to substitute other beliefs for them.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 3)
     A reaction: Spot on. There is no positive evidence for scepticism, so must just register it as the faintest of possibilities, like the existence of secretive fairies.
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?
Other minds seem to exist, because their testimony supports realism about the world [Russell, by Grayling]
     Full Idea: Russell gives an argument that other minds exist, because if one is entitled to believe this, then one can rely on the testimony of others, which, jointly with one's own experience, will give powerful support to the view that there a real spatial world.
     From: report of Bertrand Russell (Our Knowledge of the External World [1914], 3) by A.C. Grayling - Russell Ch.2
     A reaction: I rather like this argument. It is quite close to Wittgenstein's Private Language Argument, which also seems to refute scepticism about other minds. I think Russell's line, using testimony, knowledge and realism, may be better than Wittgenstein's.
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.
27. Natural Reality / D. Time / 2. Passage of Time / a. Experience of time
We never experience times, but only succession of events [Russell]
     Full Idea: There is no reason in experience to suppose that there are times as opposed to events: the events, ordered by the relations of simultaneity and succession, are all that experience provides.
     From: Bertrand Russell (Our Knowledge of the External World [1914], 4)
     A reaction: We experience events, but also have quite an accurate sense of how much time has passed during the occurrence of events. If asked how much time has lapsed, why don't we say '32 events'? How do we distinguish long events from short ones?
28. God / B. Proving God / 1. Proof of God
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?
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.
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.
