19073 | True philosophy aims at absolute unity, while our understanding sees only separation [Hegel] |
Full Idea: Everything deserving the name of philosophy has constantly been based on the consciousness of an absolute unity, where the understanding sees and accepts only separation. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: Puzzled by the role of 'understanding' here. I tend to cite that as the highest aspiration of philosophy. Hegel seems to offer a higher understanding of unity, and a weaker analytic understanding, which is part of our limited psychology. |
15624 | Free thinking has no presuppositions [Hegel] |
Full Idea: Thinking that is free is without presuppositions. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §41 Add1) | |
A reaction: Fat chance, I would have thought. Hegel's project was indeed to try to get right to the bottom of the presuppositions. My picture is always of holding one thing presupposed while you examine another, and then switching to other presuppositions. |
15631 | The ideal of reason is the unification of abstract identity (or 'concept') and being [Hegel] |
Full Idea: Abstract identity (which is what here is also called 'concept') and being are the two moments that reason seeks to unify; this unification is the Ideal of reason. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §49) | |
A reaction: Not sure I understand this, but I connect it to Aristotle's approach to the problem of being, which was to abandon the head-on approach, and aim to understand the identities of particulars and kinds. |
15612 | Older metaphysics naively assumed that thought grasped things in themselves [Hegel] |
Full Idea: The older metaphysics has the naïve presupposition that thinking grasps what things are in-themselves, that things only are what they genuinely are when they are captured in thought. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: His 'older' metaphysics is prior to Kant's critique. The less naïve version is more aware of antinomies and dialectical conflicts within thought. |
21768 | Logic is metaphysics, the science of things grasped in thoughts [Hegel] |
Full Idea: Logic coincides with metaphysics, with the science of things grasped in thoughts. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §24), quoted by Stephen Houlgate - An Introduction to Hegel 02 'Logic' | |
A reaction: Not a very clear definition, given that thinking about a table appears to be a 'thing grasped in thought'. Presumably it refers to things which can only be grasped in thought, which seems to make it entirely a priori. |
21984 | We must break up the rigidity that our understanding has imposed [Hegel] |
Full Idea: The battle of reason is the struggle to break up the rigidity to which the understanding has reduced everything. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §80Z p.115), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: This sounds like a combination of Nietzsche and later Wittgenstein, and may be one of the ideas that launches 'continental' philosophy. Recent French thinkers talk continually of 'liberation'. |
22081 | Let thought follow its own course, and don't interfere [Hegel] |
Full Idea: Let thought follow its own course; and I think badly whenever I add something of my own. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §24 Add 2), quoted by Stephen Houlgate - Hegel p.100 | |
A reaction: The idea that reason has a course of its own is a mega-assumption, which I would only accept after a lot of persuasion, which I doubt that Hegel can provide. The modern analytic idea of metaphysics as logic has a similar basis. |
15626 | Categories create objective experience, but are too conditioned by things to actually grasp them [Hegel] |
Full Idea: It is the categories that elevate mere perception into objectivity, into experience; but these concepts ...are conditioned by the given material. ...Hence the understanding, or cognition through categories, cannot become cognizant of things-in-themselves. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §43-4) | |
A reaction: As one often fears with Hegel, this sounds like a deep insight, but is less persuasive when translated into simpler English (if I've got it right!). Being 'conditioned by the material' strikes me as just what is needed for good categories. |
15616 | If truth is just non-contradiction, we must take care that our basic concepts aren't contradictory [Hegel] |
Full Idea: If truth were nothing more than lack of contradiction, one would have to examine first of all, with regard to each concept, whether it does not on its own account, contain an inner contradiction. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §33 Rem) | |
A reaction: This is a very nice thought, which modern analytic philosophers, steeped in logic, should think about. It is always presumed that a contradiction is between a proposition and its negation, not some inner feature. |
15615 | Older metaphysics became dogmatic, by assuming opposed assertions must be true and false [Hegel] |
Full Idea: The older metaphysics became dogmatism because, given the nature of finite determinations, it had to assume that of two opposed assertions (of the kind that those propositions were) one must be true and the other false. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §32) | |
A reaction: While dialethism in logic looks very dubious to me, I have every sympathy with Hegel when it comes to the reasonings of ordinary language. There it is much harder to know whether you are addressing truly opposed assertions. |
21767 | Dialectic is seen in popular proverbs like 'pride comes before a fall' [Hegel] |
Full Idea: In the domain of individual ethics, we find the consciousness of dialectic in those universally familiar proverbs 'pride goes before a fall' and 'too much wit outwits itself'. ...Joy relieves itself in tears, and melancholy can be revealed in a smile. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81), quoted by Stephen Houlgate - An Introduction to Hegel 02 'The Method' | |
A reaction: 'Too clever by half' is the English version. Hegel's dialectic suggests that each concept somehow implies its opposite, rather than a mere mercurial drift from one extreme to the other. Most pride doesn't lead to a fall. |
15639 | Socratic dialectic is subjective, but Plato made it freely scientific and objective [Hegel] |
Full Idea: It is in the Platonic philosophy that dialectic first occurs in a form which is freely scientific, and hence also objective. With Socrates, dialectical thinking still has a predominantly subjective shape, consistent with his irony. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81 Add1) | |
A reaction: I don't understand how dialectic can be 'objective', given that it is a method rather than a belief. Plato certainly seems to elevate dialectic into something almost mystical, because of what is said to be within its power. |
15638 | Dialectic is the moving soul of scientific progression, the principle which binds science together [Hegel] |
Full Idea: The dialectical constitutes the moving soul of scientific progression, and it is the principle through which alone immanent coherence and necessity enter into the content of science. ..[Add 1] It is the principle of all motion, of all life. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81) |
19070 | Superficial truth is knowing how something is, which is consciousness of bare correctness [Hegel] |
Full Idea: Truth is at first taken to mean that I know how something is. This is truth, however, only in reference to consciousness; it is formal truth, bare correctness. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: I would translate this idea as saying that bare correctness is conscious awareness of the truthmaker for some statement. Hegel then offers a 'deeper' account of the nature of truth. I would say awareness is quite separate from the concept of truth. |
5644 | In Hegel's logic it is concepts (rather than judgements or propositions) which are true or false [Hegel, by Scruton] |
Full Idea: The terms of Hegel's logic are not judgements or propositions, but rather concepts: and it is concepts, in this view, that are true or false. | |
From: report of Georg W.F.Hegel (Logic (Encyclopedia I) [1817]) by Roger Scruton - Short History of Modern Philosophy Ch.12 | |
A reaction: Quite alien to normal studies of logic, but I can make sense of a correspondence theory of truth for concepts, which might be more interesting than normal propositional or predicate logic. Does the concept of, say, a 'natural law' correspond to anything? |
19072 | In the deeper sense of truth, to be untrue resembles being bad; badness is untrue to a thing's nature [Hegel] |
Full Idea: When truth is viewed in the deeper sense, to be untrue means much the same as to be bad. A bad man is an untrue man, and man who does not behave as his notion or his vocation requires. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: See Idea 19071 for the 'deeper sense'. This seems to confirm that Hegel's deeper concept of truth resembles authenticity. I guess it will be something fulfilling the essence of the thing. Doctors must be proper doctors. Gold must be true gold? |
19071 | The deeper sense of truth is a thing matching the idea of what it ought to be [Hegel] |
Full Idea: Truth in the deeper sense is the identity between objectivity and the notion. It is in this deeper sense of truth that we speak of a true state or work of art. These are true if they are as they ought to be (their reality corresponds to their notion). | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: This seems to be a correspondence theory, but not as we know it, Jim. He seems to have a value built into truth, which sounds to me like existentialist 'authenticity'. I like what he is saying, but I would analyse it into two or more components. |
18951 | For scientific purposes there is a precise concept of 'true-in-L', using set theory [Putnam] |
Full Idea: For a language L there is a predicate 'true-in-L' which one can employ for all scientific purposes in place of intuitive truth, and this predicate admits of a precise definition using only the vocabulary of L itself plus set theory. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.2) | |
A reaction: He refers, of course, to Tarski's theory. I'm unclear of the division between 'scientific purposes' and the rest of life (which is why some people embrace 'minimal' theories of ordinary truth). I'm struck by set theory being a necessary feature. |
18953 | Modern notation frees us from Aristotle's restriction of only using two class-names in premises [Putnam] |
Full Idea: In modern notation we can consider potential logical principles that Aristotle never considered because of his general practice of looking at inferences each of whose premises involved exactly two class-names. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.3) | |
A reaction: Presumably you can build up complex inferences from a pair of terms, just as you do with pairs in set theory. |
18949 | The universal syllogism is now expressed as the transitivity of subclasses [Putnam] |
Full Idea: On its modern interpretation, the validity of the inference 'All S are M; All M are P; so All S are P' just expresses the transitivity of the relation 'subclass of'. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.1) | |
A reaction: A simple point I've never quite grasped. Since lots of syllogisms can be expressed as Venn Diagrams, in which the circles are just sets, it's kind of obvious really. So why does Sommers go back to 'terms'? See 'Term Logic'. |
18952 | '⊃' ('if...then') is used with the definition 'Px ⊃ Qx' is short for '¬(Px & ¬Qx)' [Putnam] |
Full Idea: The symbol '⊃' (read 'if...then') is used with the definition 'Px ⊃ Qx' ('if Px then Qx') is short for '¬(Px & ¬Qx)'. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.3) | |
A reaction: So ⊃ and → are just abbreviations, and not really a proper part of the language. Notoriously, though, this is quite a long way from what 'if...then' means in ordinary English, and it leads to paradoxical oddities. |
18958 | In type theory, 'x ∈ y' is well defined only if x and y are of the appropriate type [Putnam] |
Full Idea: In the theory of types, 'x ∈ y' is well defined only if x and y are of the appropriate type, where individuals count as the zero type, sets of individuals as type one, sets of sets of individuals as type two. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.6) |
18954 | Before the late 19th century logic was trivialised by not dealing with relations [Putnam] |
Full Idea: It was essentially the failure to develop a logic of relations that trivialised the logic studied before the end of the nineteenth century. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.3) | |
A reaction: De Morgan, Peirce and Frege were, I believe, the people who put this right. |
18956 | Asserting first-order validity implicitly involves second-order reference to classes [Putnam] |
Full Idea: The natural understanding of first-order logic is that in writing down first-order schemata we are implicitly asserting their validity, that is, making second-order assertions. ...Thus even quantification theory involves reference to classes. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.3) | |
A reaction: If, as a nominalist, you totally rejected classes, presumably you would get by in first-order logic somehow. To say 'there are no classes so there is no logical validity' sounds bonkers. |
18962 | Unfashionably, I think logic has an empirical foundation [Putnam] |
Full Idea: Today, the tendency among philosophers is to assume that in no sense does logic itself have an empirical foundation. I believe this tendency is wrong. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.9) | |
A reaction: I agree, not on the basis of indispensability to science, but on the basis of psychological processes that lead from experience to logic. Russell and Quine are Putnam's allies here, and Frege is his opponent. Putnam developed a quantum logic. |
21595 | Excluded middle is the maxim of definite understanding, but just produces contradictions [Hegel] |
Full Idea: The law of excluded middle is ...the maxim of the definite understanding, which would fain avoid contradiction, but in doing so falls into it. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], p.172), quoted by Timothy Williamson - Vagueness 1.5 | |
A reaction: Not sure how this works, but he would say this, wouldn't he? |
18961 | We can identify functions with certain sets - or identify sets with certain functions [Putnam] |
Full Idea: Instead of identifying functions with certain sets, I might have identified sets with certain functions. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.9) |
18955 | Having a valid form doesn't ensure truth, as it may be meaningless [Putnam] |
Full Idea: I don't think all substitution-instances of a valid schema are 'true'; some are clearly meaningless, such as 'If all boojums are snarks and all snarks are egglehumphs, then all boojums are egglehumphs'. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.3) | |
A reaction: This seems like a very good challenge to Quine's claim that it is only form which produces a logical truth. Keep deductive and semantic consequence separate, with two different types of 'logical truth'. |
15628 | The idea that contradiction is essential to rational understanding is a key modern idea [Hegel] |
Full Idea: The thought that the contradiction which is posited by the determinations of the understanding in what is rational is essential and necessary, has to be considered one of the most important and profound advances of the philosophy of modern times. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48) | |
A reaction: This is the aspect of Kant's philosophy which launched the whole career of Hegel. Hegel is the philosopher of the antinomies. Graham Priest is his current representative on earth. |
15629 | Tenderness for the world solves the antinomies; contradiction is in our reason, not in the essence of the world [Hegel] |
Full Idea: The solution to the antinomies is as trivial as they are profound; it consists merely in a tenderness for the things of this world. The stain of contradiction ought not to be in the essence of what is in the world; it must belong only to thinking reason. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48 Rem) | |
A reaction: A rather Wittgensteinian remark. I love his 'tenderness for the things of this world'! I'm not clear why our thinking should be considered to be inescapably riddled with basic contradictions, as Hegel seems to imply. Just make more effort. |
15630 | Antinomies are not just in four objects, but in all objects, all representations, all objects and all ideas [Hegel] |
Full Idea: The main point that has to be made is that antinomy is found not only in Kant's four particular objects taken from cosmology, but rather in all objects of all kinds, in all representations, concepts and ideas. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48 Rem) | |
A reaction: I suppose Heraclitus and Empedocles, with their oppositional accounts of reality, are the ancestors of this worldview. I just don't feel that sudden flood of insight from this idea of Hegel that comes from some of the other great philsophical theories. |
18959 | Sets larger than the continuum should be studied in an 'if-then' spirit [Putnam] |
Full Idea: Sets of a very high type or very high cardinality (higher than the continuum, for example) should today be investigated in an 'if-then' spirit. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.7) | |
A reaction: This attitude goes back to Hilbert, but it fits with Quine's view of what is indispensable for science. It is hard to see a reason for the cut-off, just looking at the logic of expanding sets. |
22078 | Even simple propositions about sensations are filled with categories [Hegel] |
Full Idea: Categories, like 'being', or 'individuality', are already mingled into every proposition, even when it has a completely sensible content, such as "this leaf is green". | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §246 Add), quoted by Stephen Houlgate - Hegel p.95 | |
A reaction: This is the source of the idea that observation is theory-laden (which tracks back to Kant). Not Duhem, who gets the credit among analytic philosophers. Quine obviously never read Hegel. But the idea is overrated. |
15634 | Thought about particulars is done entirely through categories [Hegel] |
Full Idea: As an activity of the particular, thinking has the categories as its only product and content. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §62) | |
A reaction: There seems to be an interesting implication in this remark (taken in isolation!) that one can somehow transcend the categories when one begins to think about the universal. Are the universal and the categories not connected? |
18957 | Nominalism only makes sense if it is materialist [Putnam] |
Full Idea: Nominalists must at heart be materialists, or so it seems to me: otherwise their scruples are unintelligible. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.5) | |
A reaction: This is modern nominalism - the rejection of abstract objects. I largely plead guilty to both charges. |
18950 | Physics is full of non-physical entities, such as space-vectors [Putnam] |
Full Idea: Physics is full of references to such 'non-physical' entities as state-vectors, Hamiltonians, Hilbert space etc. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.2) | |
A reaction: I take these to be concepts which are 'abstracted' from the physical facts, and so they don't strike me as being much of an ontological problem, or an objection to nominalism (which Putnam takes them to be). |
21981 | The one substance is formless without the mediation of dialectical concepts [Hegel] |
Full Idea: As intuitively accepted by Spinoza without a previous mediation by dialectic, substance is as it were a dark shapeless abyss which engulfs all definite content as radically null, and produces from itself nothing that has a positive substance of its own. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §151Z p.215), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.6 | |
A reaction: This seems to be an expression of idealism, since only what is conceptualised can exist. |
15637 | Essence is the essential self-positing unity of immediacy and mediation [Hegel] |
Full Idea: The entire second part of the 'Logic', the doctrine of Essence, deals with the essential self-positing unity of immediacy and mediation. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §65) | |
A reaction: He is referring to his book 'Science of Logic'. I don't really understand this, but that essence 'posits' the unity of a thing catches my attention. |
15613 | Real cognition grasps a thing from within itself, and is not satisfied with mere predicates [Hegel] |
Full Idea: In genuine cognition ...an object determines itself from within itself, and does not acquire its predicates in an external way. If we proceed by way of predication, the spirit gets the feeling that the predicates cannot exhaust what they are attached to. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: I take this to be a glimpse of Hegel's notoriously difficult account of essence. Place this alongside Locke's distinction between Nominal and Real essences. Once we have the predicates, we want to grasp their source. |
15636 | The Cogito is at the very centre of the entire concern of modern philosophy [Hegel] |
Full Idea: The proposition 'Cogito Ergo Sum' stands at the very centre, so to speak, of the entire concern of modern philosophy. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §64 Rem) | |
A reaction: I distinguish two approaches to philosophy: the Parmenidean (which starts from the nature of being), and the Cartesian (which starts from the fact of consciousness). This remark confirms that Hegel is firmly in the latter school. |
22300 | Existence is just a set of relationships [Hegel] |
Full Idea: Everything that exists stands in correlation, and this correlation is the veritable nature of existence. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], p.235 (1892)), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 23 'Abs' |
15609 | The sensible is distinguished from thought by being about singular things [Hegel] |
Full Idea: The distinction of the sensible from thought is to be located in that fact that the determination of the sensible is singularity. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §20 Rem) | |
A reaction: Compare Idea 15608, where we find that thought concerns universals. What a very clear thinker Hegel was! |
15625 | Sense perception is secondary and dependent, while thought is independent and primitive [Hegel] |
Full Idea: What can be perceived by the senses is really secondary and not self-standing, while thoughts, on the contrary, are what is genuinely independent and primitive. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §41 Add2) | |
A reaction: Although this is post-Kant, it strikes me as a perfect slogan for rationalism. Personally I would say that such a dichotomy is becoming a historical relic, in the light of modern understanding of the brain. Experience and thought are inextricable. |
15620 | Empiricism contains the important idea that we should see knowledge for ourselves, and be part of it [Hegel] |
Full Idea: We must recognise the important principle of freedom that lies in Empiricism; namely, that what ought to count in our human knowing, we ought to see for ourselves, and to know ourselves as present in it. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: Like Idea 15619, this is an interesting and perceptive remark, from a philosopher who seems a long way from empiricism. I presume he will be thinking mainly of Hume, via Kant. Personally I prefer Locke. |
15619 | Empiricism made particular knowledge possible, and blocked wild claims [Hegel] |
Full Idea: Empiricism resulted from a need for concrete content, as opposed to abstract theories that cannot advance from universal generalizations to the particular, and for a firm hold against the possibility of proving any claim at all in the field. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §37) | |
A reaction: That sounds about right, and makes you wonder why Hegel wasn't an empiricist. |
15622 | Empiricism unknowingly contains and uses a metaphysic, which underlies its categories [Hegel] |
Full Idea: Empiricism operates without knowing that it contains a metaphysics and is engaged in it, and that it is using categories and their connections in a totally uncritical and unconscious manner. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: I doubt whether this is true of modern empiricists, who have been challenged so often from within their own ranks on so many things. I'm not even sure that it is true of Locke and Hume, apart from the way in which all philosophers are unaware of things. |
15621 | Empiricism of the finite denies the supersensible, and can only think with formal abstraction [Hegel] |
Full Idea: Inasmuch as Empiricism restricts itself to what is finite, the consistent carrying through of its programme denies the supersensible altogether, ..and it leaves thinking with abstraction only, [i.e.] with formal universality and identity. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: I'm not clear how a denial of empiricism allows you (with intellectual integrity) to embrace 'the supersensible'. The set theoretic account of higher levels of infinity looks like a nice test case. |
15632 | The Humean view stops us thinking about perception, and finding universals and necessities in it [Hegel] |
Full Idea: The Humean standpoint proclaims the thinking of our perceptions to be inadmissible; i.e. the eliciting of the universal and necessary out of those perceptions. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §50) | |
A reaction: Obviously Hume permits 'relations of ideas', but presumably the point is that his approach only legitimates a rather passive abstraction from experience, rather than an active application of a priori concepts to it. A fair criticism. See Bonjour. |
15623 | Humean scepticism, unlike ancient Greek scepticism, accepts the truth of experience as basic [Hegel] |
Full Idea: Humean scepticism should be very carefully distinguished from Greek scepticism. In Humean scepticism, the truth of the empirical, the truth of feeling and intuition is taken as basic. ..Greek scepticism turned itself against the sensible. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §39 Rem) | |
A reaction: This seems right, and Hume himself was quite contemptuous of the sort of scepticism found in the ideas of Sextus Empiricus. |
18960 | Most predictions are uninteresting, and are only sought in order to confirm a theory [Putnam] |
Full Idea: Scientists want successful predictions in order to confirm their theories; they do not want theories in order to obtain the predictions, which are in some cases of not the slightest interest in themselves. | |
From: Hilary Putnam (Philosophy of Logic [1971], Ch.8) | |
A reaction: Equally, we might only care about the prediction, and have no interest at all in the theory. Farmers want weather predictions, not a PhD in meteorology. |
15617 | In abstraction, beyond finitude, freedom and necessity must exist together [Hegel] |
Full Idea: Considered as abstractly confronting one another, freedom and necessity pertain to finitude only and are valid only on its soil. A freedom with no necessity in it, and a mere necessity without freedom, are determinations that are abstract and thus untrue. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §35 Add) | |
A reaction: This is, presumably, the Hegelian dialectical nature of things, that contradictories are bound together. We must struggle hard to undestand a freedom bound by necessity, and a necessity which contains freedom. (Good luck). |
15608 | The act of thinking is the bringing forth of universals [Hegel] |
Full Idea: Thinking as an activity is the active universal, and indeed the self-actuating universal, since the act, or what is brought forth, is precisely the universal. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §20) | |
A reaction: One should contemplate animal thought in the light of this remark. Thought requires the recognition of types of things, and resemblances, and repetitions, and patterns. Language consists almost entirely of universals. |
21986 | Hegel's system has a vast number of basic concepts [Hegel, by Moore,AW] |
Full Idea: For Hegel the full system of concepts ...contains many more than Kant's twelve. | |
From: report of Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §60Z) by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: This offers some sort of conceptual scheme, but not the structured one that Kant proposes. The sequence of dialectical mediation imposes some sort of shape on the concepts. |
15607 | We don't think with concepts - we think the concepts [Hegel] |
Full Idea: There is a saying that, when we have grasped a concept, we still do not know what to think with it. But there is nothing to be thought with a concept save the concept itself. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §03 Rem) | |
A reaction: Analytic philosophers should read Hegel on concepts, because he approaches the matter so very differently, and seems to be the root of the continental approach to such things. He seems to me to talk more sense than Frege on the subject. |
15610 | Active thought about objects produces the universal, which is what is true and essential of it [Hegel] |
Full Idea: When thinking is taken as active with regard to ob-jects, as the thinking-over of something, then the universal - as the product of the activity - contains the value of the matter, what is essential, inner, true. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §21) | |
A reaction: I prefer to talk of 'general terms' rather than 'universals'. If 'tiger' is coined for the first one, but must be applicable to subsequent tigers, it has to generalise what they all have in common. Locke's 'nominal' essence, I would say. |
15614 | Old metaphysics tried to grasp eternal truths through causal events, which is impossible [Hegel] |
Full Idea: When finite things are grasped according to the determinations of cause and effect they are known in their finitude. But objects of reason cannot be determined through such finite predicates, and the attempt to do this was the defect of older metaphysics. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: This sounds the launching point for a grand philosophical system which makes scientifically inclined philosophers feel very nervous indeed. I think I prefer the old (pre-Kantian) metaphysics. |
8430 | Causal statements are used to explain, to predict, to control, to attribute responsibility, and in theories [Kim] |
Full Idea: The function of causal statements is 1) to explain events, 2) for predictive usefulness, 3) to help control events, 4) with agents, to attribute moral responsibility, 5) in physical theory. We should judge causal theories by how they account for these. | |
From: Jaegwon Kim (Causes and Counterfactuals [1973], p.207) | |
A reaction: He suggests that Lewis's counterfactual theory won't do well on this test. I think the first one is what matters. Philosophy aims to understand, and that is achieved through explanation. Regularity and counterfactual theories explain very little. |
8396 | Many counterfactuals have nothing to do with causation [Kim, by Tooley] |
Full Idea: Kim has pointed out that there are a number of counterfactuals that have nothing to do with causation. If John marries Mary, then if John had not existed he would not have married Mary, but that is not the cause of their union. | |
From: report of Jaegwon Kim (Causes and Counterfactuals [1973], 5.2) by Michael Tooley - Causation and Supervenience | |
A reaction: One might not think that this mattered, but it leaves the problem of distinguishing between the causal counterfactuals and the rest (and you mustn't mention causation when you are doing it!). |
8429 | Counterfactuals can express four other relations between events, apart from causation [Kim] |
Full Idea: Counterfactuals can express 'analytical' dependency, or the fact that one event is part of another, or an action done by doing another, or (most interestingly) an event can determine another without causally determining it. | |
From: Jaegwon Kim (Causes and Counterfactuals [1973], p.205) | |
A reaction: [Kim gives example of each case] Counterfactuals can even express a relation that involves no dependency. Or they might just involve redescription, as in 'If Scott were still alive, then the author of "Waverley" would be too'. |
8428 | Causation is not the only dependency relation expressed by counterfactuals [Kim] |
Full Idea: The sort of dependency expressed by counterfactual relations is considerably broader than strictly causal dependency, and causal dependency is only one among the heterogeneous group of dependency relationships counterfactuals can express. | |
From: Jaegwon Kim (Causes and Counterfactuals [1973], p.205) | |
A reaction: In 'If pigs could fly, one and one still wouldn't make three' there isn't even a dependency. Kim has opened up lines of criticism which make the counterfactual analysis of causation look very implausible to me. |
4781 | Many counterfactual truths do not imply causation ('if yesterday wasn't Monday, it isn't Tuesday') [Kim, by Psillos] |
Full Idea: Kim gives a range of examples of counterfactual dependence without causation, as: 'if yesterday wasn't Monday, today wouldn't be Tuesday', and 'if my sister had not given birth, I would not be an uncle'. | |
From: report of Jaegwon Kim (Causes and Counterfactuals [1973]) by Stathis Psillos - Causation and Explanation §3.3 | |
A reaction: This is aimed at David Lewis. The objection seems like commonsense. "If you blink, the cat gets it". Causal claims involve counterfactuals, but they are not definitive of what causation is. |
15635 | The older conception of God was emptied of human features, to make it worthy of the Infinite [Hegel] |
Full Idea: In earlier times, every type of so-called anthropomorphic representation was banished from God as finite, and hence unworthy of the Infinite; and as a result he had already grown into something remarkably empty. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §62 Rem) | |
A reaction: Hegel favoured Christianity, because of its human aspect. His description fits Islam, where indeed the concept of God seems so drain of particularity that there is little in it to doubt, which might explain the durability of that religion. |
21980 | God is the absolute thing, and also the absolute person [Hegel] |
Full Idea: It is true that God ...is the absolute thing: he is however no less the absolute person. That he is the absolute person however is a point which the philosophy of Spinoza never reached. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §151Z p.214), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.6 | |
A reaction: Moore says Hegel was a Spinozist, in his commitment to a single substance, but his idea of God is very different, presumably because consciousness and concepts are so important to Hegel. Hegel needs a Lockean abstract notion of 'person' here. |
15618 | If God is the abstract of Supremely Real Essence, then God is a mere Beyond, and unknowable [Hegel] |
Full Idea: When the concept of God is apprehended merely as that of the abstract of Supremely Real Essence, then God becomes for us a mere Beyond, and there can be no further talk of the cognition of God. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §36 Add) |
15633 | We establish unification of the Ideal by the ontological proof, deriving being from abstraction of thinking [Hegel] |
Full Idea: One unification through which the Ideal is to be established starts from the abstraction of thinking and goes on to the determination for which being alone remains; this is the ontological proof that God is there. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §51) | |
A reaction: It should come as no surprise that a philosopher who so passionately endorses pure thinking, in opposition to empiricism, should end up endorsing the highly implausible ontological argument for God's existence. Jacquette gets existence from reason. |
