21474 | Metaphysics studies the inexplicable ends of explanation [Schopenhauer] |
Full Idea: The plummet touches the bottom of the sea now at a greater depth, now at a less, but is bound to reach it somewhere sooner or later; the study of this inexplicable devolves upon metaphysics. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], I:1) | |
A reaction: This definition of metapysics contains the germ of despair about the subject. Does he hope that metaphysicians can explain what nobody else can? |
21470 | For me the objective thing-in-itself is the will [Schopenhauer] |
Full Idea: Thing in itself signifies that which exists independently of our perception, that which actually is; …to Kant it was '= x'; to me it is will. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], IV:61) | |
A reaction: Does he mean his own will, which is plausible since he has direct experience of it, or is he referring will in general - whatever that is? |
15797 | All structures are dispositional, objects are dispositions sets, and events manifest dispositions [Fetzer] |
Full Idea: I propose a dispositional ontology for the physical world, according to which a) every structural property is a dispositional one, b) a physical object is an ordered set of dispositions, and c) every event manifests a dispositional property of the world. | |
From: J.H. Fetzer (A World of Dispositions [1977], Intro) | |
A reaction: Mumford says this is consistent with ontology as a way of describing the world, rather than being facts about the world. I like Fetzer's sketch, which sounds to have a lot in common with 'process philosophy'. |
15800 | All events and objects are dispositional, and hence all structural properties are dispositional [Fetzer] |
Full Idea: Every atomic event in the world's history is a manifestation of some dispositional property of the world and every physical object is an instantiation of some set of dispositions; hence, every structural property is dispositional in kind. | |
From: J.H. Fetzer (A World of Dispositions [1977], 5) | |
A reaction: I quite like this drastic view, but there remains the intuition that there must always be something which has the disposition. That may be because I have not yet digested the lessons of modern physics. |
13768 | Validity can preserve certainty in mathematics, but conditionals about contingents are another matter [Edgington] |
Full Idea: If your interest in logic is confined to applications to mathematics or other a priori matters, it is fine for validity to preserve certainty, ..but if you use conditionals when arguing about contingent matters, then great caution will be required. | |
From: Dorothy Edgington (Conditionals [2001], 17.2.1) |
13770 | There are many different conditional mental states, and different conditional speech acts [Edgington] |
Full Idea: As well as conditional beliefs, there are conditional desires, hopes, fears etc. As well as conditional statements, there are conditional commands, questions, offers, promises, bets etc. | |
From: Dorothy Edgington (Conditionals [2001], 17.3.4) |
13764 | Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? [Edgington] |
Full Idea: Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? Are they non-truth-functional, like 'because' or 'before'? Do the values of A and B, in some cases, leave open the value of 'If A,B'? | |
From: Dorothy Edgington (Conditionals [2001], 17.1) | |
A reaction: I would say they are not truth-functional, because the 'if' asserts some further dependency relation that goes beyond the truth or falsity of A and B. Logical ifs, causal ifs, psychological ifs... The material conditional ⊃ is truth-functional. |
13765 | 'If A,B' must entail ¬(A & ¬B); otherwise we could have A true, B false, and If A,B true, invalidating modus ponens [Edgington] |
Full Idea: If it were possible to have A true, B false, and If A,B true, it would be unsafe to infer B from A and If A,B: modus ponens would thus be invalid. Hence 'If A,B' must entail ¬(A & ¬B). | |
From: Dorothy Edgington (Conditionals [2001], 17.1) | |
A reaction: This is a firm defence of part of the truth-functional view of conditionals, and seems unassailable. The other parts of the truth table are open to question, though, if A is false, or they are both true. |
21479 | Knowledge is not power! Ignorant people possess supreme authority [Schopenhauer] |
Full Idea: Knowledge is power. The devil it is! One man can have a great deal of knowledge without its giving him the least power, while another possesses supreme authority but next to no knowledge. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], III:43) | |
A reaction: He is referring to Bacon's famous adage. Bacon may be right about military affairs, but not about politics. |
21476 | A priori propositions are those we could never be seriously motivated to challenge [Schopenhauer] |
Full Idea: A dictate of reason is the name we give to certain propositions which we hold to be true without investigation, and of which we think ourselves so firmly convinced we should be incapable of seriously testing them even if we wanted to. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], I:12) | |
A reaction: This is closer to the cautious way modern thinkers are inclined to express the idea. Even Quine would be reasonably happy with this. |
21473 | All knowledge and explanation rests on the inexplicable [Schopenhauer] |
Full Idea: The fundament upon which all our knowledge and learning rests is the inexplicable. It is to this that every explanation, through few or many intermediary stages, leads. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], I:1) | |
A reaction: This is obviously true, and the only question is whether it is a necessary or a contingent truth. |
21478 | Half our thinking is unconscious, and we reach conclusions while unaware of premises [Schopenhauer] |
Full Idea: One might almost believe that half our thinking takes place unconsciously.. Usually we arrive at a conclusion without having clearly thought about the premises which lead to it. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], III:40) | |
A reaction: Schopenhauer was a major pioneer of this crucial idea. I'm beginning to think it is much greater than a half. |
21477 | We don't control our own thinking [Schopenhauer] |
Full Idea: Thoughts come not when we want but when they want. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], III:37) | |
A reaction: One of my favourite Nietzsche ideas originated in Schopenhauer! |
21475 | All of our concepts are borrowed from perceptual knowledge [Schopenhauer] |
Full Idea: The entire property of a concept consists in nothing more than what has been begged and borrowed from perceptual knowledge, which is the true and inexhaustible source of all insight. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], I:9) | |
A reaction: Schopenhauer is usually seen as a sort of idealist, but this is a full endorsement of the empirical view of concepts, to which I largely subscribe. Note that he talks of 'knowledge', rather than of 'experience'. |
21372 | Aesthetics concerns how we can take pleasure in an object, with no reference to the will [Schopenhauer] |
Full Idea: The central problem of aesthetics is how satisfaction with and pleasure in an object are possible without any reference thereof to our willing. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], II:415), quoted by Christopher Janaway - Schopenhauer 6 'Aesthetic' | |
A reaction: This does seem a good distinction. We can divide pleasures into willed and unwilled. Compare thinking that some remote stranger (in a photograph) is very beautiful, with falling in love with someone. |
21488 | The beautiful is a perception of Plato's Forms, which eliminates the will [Schopenhauer] |
Full Idea: In the beautiful we always perceive the intrinsic and primary form of animate and inanimate nature, that is to say Plato's Ideas thereof. …When an aesthetic perception occurs the will completely vanishes from consciousness. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XIX:205) | |
A reaction: An essential Schopenauer idea. Iris Murdoch said something similar. |
21483 | Man is essentially a dreadful wild animal [Schopenhauer] |
Full Idea: Man is at bottom a dreadful wild animal. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], VIII:114) | |
A reaction: As an example he cites the slave owners in the United States. |
21466 | Pleasure is weaker, and pain stronger, than we expect [Schopenhauer] |
Full Idea: As a rule we find pleasure much less pleasurable, pain much more painful than we expected. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XII:149) | |
A reaction: Never go on holiday with Schopenhauer. This is more accurate about pain, I think. |
21484 | A man's character can be learned from a single characteristic action [Schopenhauer] |
Full Idea: As a botanist can recognise the whole plant from one leaf, …so an accurate knowledge of a man's character can be arrived at from a single characteristic action. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], VIII:118) | |
A reaction: Very true. Great novelists specialise in such observations. One word can reveal a character, as well as one action. |
21482 | The five Chinese virtues: pity, justice, politeness, wisdom, honesty [Schopenhauer] |
Full Idea: The Chinese name five cardinal virtues: pity, justice, politeness, wisdom and honesty. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], VIII:110) | |
A reaction: I like politeness being on the list, though it seems rather superficial to be a virtue of character. Respect would be better. |
21481 | Buddhists wisely start with the cardinal vices [Schopenhauer] |
Full Idea: Because of their profounder ethical and metaphysical insight, the Buddhists start not with the cardinal virtues but with cardinal vices, …which are lust, sloth, wrath and avarice (and maybe hatred). | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], VIII:110) | |
A reaction: This may be right. Our lives are affected much more by the vices of others than by their virtues, and most virtuous behaviour aims at rectifying the bad effects of other people's vices. |
21480 | Boredom is only felt by those clever enough to need activity [Schopenhauer] |
Full Idea: Only in the cleverest animals such as dogs and apes does the need for activity, and with that boredom, make itself felt. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], III:50) | |
A reaction: But it is much more frequently young creatures, of almost any kind, that seek constant activity, and get continually restless. The most active adults need not be the cleverest. |
21469 | Human life is a mistake, shown by boredom, which is direct awareness of the fact [Schopenhauer] |
Full Idea: Human life must be some kind of mistake. ...Boredom is a direct proof that existence is in itself valueless, for boredom is nothing other than the sensation of the emptiness of existence. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XI:146) | |
A reaction: I think it is a good advertisement for existentialism that it makes something more out of boredom than Schopenhauer does. |
21485 | The state only exists to defend citizens, from exterior threats, and from one another [Schopenhauer] |
Full Idea: The state is essentially no more than an institution for the protection of the whole against attacks from without, and the protection of its individual members from attacks by one another. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], IX:123) | |
A reaction: He then has a swipe at Hegel for his inflated idea of the importance of the state. Schopenhauer is close to Hobbes on this one. |
21486 | Poverty and slavery are virtually two words for the same thing [Schopenhauer] |
Full Idea: Poverty and slavery are only two forms - on might almost say two words for - the same thing, the essence of which is that a man's energies are expended for the most part not on his own behalf but on that of others. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], IX:125) | |
A reaction: The modern world is full of people who righteously despise slavery, but think only of the poor that it serves them right. |
21487 | The freedom of the press to sell poison outweighs its usefulness [Schopenhauer] |
Full Idea: Freedom of the press must be regarded as a permit to sell poison. …I very much fear, therefore, that the dangers of press freedom outweigh its usefulness. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], IX:127) | |
A reaction: On the whole the modern world disagrees with this view, but watching the popular press in Britain in the last twenty years has made me sympathise with Schopenhauer. |
21471 | If suicide was quick and easy, most people would have done it by now [Schopenhauer] |
Full Idea: Perhaps there is no one alive who would not already have put an end to his life if this end were something purely negative, a sudden cessation of existence. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XIII:158) | |
A reaction: Nonsense, on the whole, but it is a nice question how many people would do it if it only took a painless instant. |
21467 | Would humanity still exist if sex wasn't both desired and pleasurable? [Schopenhauer] |
Full Idea: If the act of procreation were neither the outcome of a desire nor accompanied by feelings of pleasure, but a matter to be decided on the basis of purely rational considerations, is it likely the human race would still exist? | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XII:156) | |
A reaction: This is almost certainly correct in the modern world. In tougher economic circumstances people seem desperate to have children who will help them survive. |
15798 | Kinds are arrangements of dispositions [Fetzer] |
Full Idea: Kinds of things are specific arrangements of dispositions. | |
From: J.H. Fetzer (A World of Dispositions [1977], 2) | |
A reaction: A 'disposition' doesn't seem quite the right word for what is basic to the physical world, though Harré and Madden make a good case for the 'fields' of physic being understood in that way. I prefer 'power', though that doesn't solve anything. |
15799 | Lawlike sentences are general attributions of disposition to all members of some class [Fetzer] |
Full Idea: Lawlike sentences are conceived as logically general dispositional statements attributing permanent dispositional properties to every member of a reference class. ...Their basic form is that of subjunctive generalizations. | |
From: J.H. Fetzer (A World of Dispositions [1977], 3) | |
A reaction: I much prefer talk of 'lawlike sentences' to talk of 'laws'. At least they imply that the true generalisations about nature are fairly fine-grained. Why not talk of 'generalisations' instead of 'laws'? Fetzer wants dispositions to explain everything. |
21472 | Only religion introduces serious issues to uneducated people [Schopenhauer] |
Full Idea: Religion is the only means of introducing some notion of the high significance of life into the uncultivated heads of the masses. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XV:174) | |
A reaction: Cf Philip Larkin's poem 'Church Going'. On the whole Schopenhauer didn't actually believe that our lives had any 'high significance'. |
21468 | The Creator created the possibilities for worlds, so should have made a better one than this possible [Schopenhauer] |
Full Idea: The Creator created not only the world, but also created possibility itself; therefore he should have created the possibility of a better world than this one. | |
From: Arthur Schopenhauer (Parerga and Paralipomena [1851], XII:156) | |
A reaction: This is explicitly a response to Leibniz's claim that the Creator selected the best of all possible worlds from the available options. The Euthyphro Question hovers here: must the Creator accept what is possible (the platonic view), or create possibility? |
