| 8368 | A correct definition is what can be substituted without loss of meaning [Ducasse] |
| Full Idea: A definition of a word is correct if the definition can be substituted for the word being defined in an assertion without in the least changing the meaning which the assertion is felt to have. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §1) | |
| A reaction: This sounds good, but a very bland and uninformative rephrasing would fit this account, without offering anything very helpful. The word 'this' could be substituted for a lot of object words. A 'blade' is 'a thing always attached to a knife handle'. |
| 4581 | Virtues and vices are like secondary qualities in perception, found in observers, not objects [Hume] |
| Full Idea: Vice and virtue may be compared to sounds, colours, heat and cold, which, according to modern philosophy, are not qualities in objects but perceptions in the mind. | |
| From: David Hume (Letters [1739], to Hutcheson 1740) | |
| A reaction: Very revealing about the origin of the is/ought idea, but this is an assertion rather than an argument. Most Greeks treat value as a primary quality of things (e.g. life, harmony, beauty, health). |
| 4580 | All virtues benefit either the public, or the individual who possesses them [Hume] |
| Full Idea: I desire you to consider if there be any quality that is virtuous, without having a tendency either to the public good or to the good of the person who possesses it. | |
| From: David Hume (Letters [1739], to Hutcheson 1739) | |
| A reaction: Obviously this is generally true. How, though, does it benefit the individual to secretly preserve their integrity? I go round to visit a friend to repay a debt; I am told they have died; I quietly leave some money on the table and leave. Why? |
| 21075 | The state of nature always involves the threat of war [Kant] |
| Full Idea: The state of nature is a state of war. For even if it does not involve active hostilities, it involves a constant threat of their breaking out. | |
| From: Immanuel Kant (Perpetual Peace [1795], 2) | |
| A reaction: Kant is siding with Hobbes against Rousseau, despite Rousseau's claim that Hobbes's pessimism concerns a more advanced situation that the true (and peaceful) state of nature. |
| 20569 | Kant made the social contract international and cosmopolitan [Kant, by Oksala] |
| Full Idea: Kant developed the social contract theory into an international and cosmopolitan idea. | |
| From: report of Immanuel Kant (Perpetual Peace [1795]) by Johanna Oksala - Political Philosophy: all that matters Ch.6 | |
| A reaction: That is, the contract both operates between states, and rises above them. I found this idea rather thrilling when I first met it (listening to Onora O'Neill). But then I remain a child of the Englightenment. |
| 21079 | The a priori general will of a people shows what is right [Kant] |
| Full Idea: It is precisely the general will as it is given a priori, within a single people or in the mutual relationships of various peoples, which alone determines what is right among men. | |
| From: Immanuel Kant (Perpetual Peace [1795], App 1) | |
| A reaction: The clearest quotation for showing Kant's debt to Rousseau. Why should Rousseau bother to have a real assembly of the people, if the General Will can be worked out a priori? Indeed, the a priori version must be deemed superior to any meeting. |
| 21077 | Each nation should, from self-interest, join an international security constitution [Kant] |
| Full Idea: Each nation, for the sake of its own security, can and ought to demand of the others that they should enter along with it into a constitution, similar to the civil one, within which the rights of each could be secured. | |
| From: Immanuel Kant (Perpetual Peace [1795], 2.2nd) | |
| A reaction: Not sure how close the United Nations takes us to this. You have to admire Kant for this one. |
| 21078 | A constitution must always be improved when necessary [Kant] |
| Full Idea: Changes for the better are necessary, in order that the constitution may constantly approach the optimum end prescribed by laws of right. | |
| From: Immanuel Kant (Perpetual Peace [1795], App 1) | |
| A reaction: This should be a clause in every constitution. It is crazy to feel trapped by a misjudgement or outdated view of your ancestors. |
| 21076 | Equality is where you cannot impose a legal obligation you yourself wouldn't endure [Kant] |
| Full Idea: Rightful equality within a state is a relationship among citizens where no-one can put anyone else under a legal obligation without submitting simultaneously to a law which requires that he can be put under the same kind of obligation by the other person. | |
| From: Immanuel Kant (Perpetual Peace [1795], 2.1st n) | |
| A reaction: This appears only to be legal equality, rather than political or economic or social equality. |
| 20570 | There is now a growing universal community, and violations of rights are felt everywhere [Kant] |
| Full Idea: The peoples of the earth have entered in varying degrees into a universal community, and it has developed to the point where a violation of rights in one part of the world is felt everywhere. | |
| From: Immanuel Kant (Perpetual Peace [1795], 'Third') | |
| A reaction: I hope slavery was at the forefront of his mind when he wrote that. It is only in very recent times (since about 1960?) that major violations of rights are felt to matter to the whole human race. A long way to go, though. |
| 20571 | There are political and inter-national rights, but also universal cosmopolitan rights [Kant] |
| Full Idea: The idea of a cosmopolitan right is not fantastic and overstrained; it is a necessary complement to the unwritten code of political and international right, transforming it into a universal right of humanity. | |
| From: Immanuel Kant (Perpetual Peace [1795], 'Third') | |
| A reaction: The interesting thought is that there are no 'natural rights', but there can be universal rights insofar as there exists a universal community. See the UN Declaration of Human Rights c.1948. |
| 21073 | Hiring soldiers is to use them as instruments, ignoring their personal rights [Kant] |
| Full Idea: The hiring of men to kill or be killed seems to mean using them as mere machines and insturments in the hands of someone else (the state), which cannot easily be reconciled with the rights of man in one's own person. | |
| From: Immanuel Kant (Perpetual Peace [1795], 1.3) | |
| A reaction: Kant was not a pacificist, though this makes him sound like one. Some men go off to war with enthusiasm, and then regret it. Exploitation of rational beings may be the worst sin in Kant's Enlightenment world. |
| 21074 | Some trust in the enemy is needed during wartime, or peace would be impossible [Kant] |
| Full Idea: It must remain possible, even in wartime, to have some sort of trust in the attitude of the enemy, otherwise peace could not be concluded and the hostilities would turn into a war of extermination. | |
| From: Immanuel Kant (Perpetual Peace [1795], 1.6) | |
| A reaction: Consider the 'unconditional surrender' approach to the Nazis in 1944, and the peace of May 1945, made with very different Germans. How do you make peace with an enemy you cannot trust? |
| 8367 | Causation is defined in terms of a single sequence, and constant conjunction is no part of it [Ducasse] |
| Full Idea: The correct definition of the causal relation is to be framed in terms of one single case of sequence, and constancy of conjunction is therefore no part of it. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], Intro) | |
| A reaction: This is the thesis of Ducasse's paper. I immediately warm to it. I take constant conjunction to be a consequence and symptom of causation, not its nature. There is a classic ontology/epistemology confusion to be avoided here. |
| 4579 | The idea of a final cause is very uncertain and unphilosophical [Hume] |
| Full Idea: Your sense of 'natural' is founded on final causes, which is a consideration that appears to me pretty uncertain and unphilosophical. | |
| From: David Hume (Letters [1739], to Hutcheson 1739) | |
| A reaction: This is the rejection of Aristotelian teleology by modern science. I agree that the notion of utterly ultimate final cause is worse than 'uncertain' - it is an impossible concept. Nevertheless, I prefer Aristotle to Hume. Nature can teach us lessons. |
| 8372 | We see what is in common between causes to assign names to them, not to perceive them [Ducasse] |
| Full Idea: The part of a generalization concerning what is common to one individual concrete event and the causes of certain other events of the same kind is involved in the mere assigning of a name to the cause and its effect, but not in the perceiving them. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §5) | |
| A reaction: A nice point, that we should keep distinct the recognition of a cause, and the assigning of a general name to it. Ducasse is claiming that we can directly perceive singular causation. |
| 8369 | Causes are either sufficient, or necessary, or necessitated, or contingent upon [Ducasse] |
| Full Idea: There are four causal connections: an event is sufficient for another if it is its cause; an event is necessary for another if it is a condition for it; it is necessitated by another if it is an effect; it is contingent upon another if it is a resultant. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §2) | |
| A reaction: An event could be a condition for another without being necessary. He seems to have missed the indispensable aspect of a necessary condition. |
| 8373 | When a brick and a canary-song hit a window, we ignore the canary if we are interested in the breakage [Ducasse] |
| Full Idea: If a brick and the song of a canary strike a window, which breaks....we can truly say that the song of the canary had nothing to do with it, that is, in so far as what occurred is viewed merely as a case of breakage of window. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §5) | |
| A reaction: This is the germ of Davidson's view, that causation is entirely dependent on the mode of description, rather than being an actual feature of reality. If one was interested in the sound of the breakage, the canary would become relevant. |
| 8370 | A cause is a change which occurs close to the effect and just before it [Ducasse] |
| Full Idea: The cause of the particular change K was such particular change C as alone occurred in the immediate environment of K immediately before. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §3) | |
| A reaction: The obvious immediately difficulty would be overdetermination, as when it rains while I am watering my garden. The other problem would coincidence, as when I clap my hands just before a bomb goes off. |
| 8371 | Recurrence is only relevant to the meaning of law, not to the meaning of cause [Ducasse] |
| Full Idea: The supposition of recurrence is wholly irrelevant to the meaning of cause: that supposition is relevant only to the meaning of law. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §4) | |
| A reaction: This sounds plausible, especially if our notion of laws of nature is built up from a series of caused events. But we could just have an ontology of 'similar events', out of which we build laws, and 'causation' could drop out (á la Russell). |
| 8374 | We are interested in generalising about causes and effects purely for practical purposes [Ducasse] |
| Full Idea: We are interested in causes and effects primarily for practical purposes, which needs generalizations; so the interest of concrete individual facts of causation is chiefly an indirect one, as raw material for generalizations. | |
| From: Curt Ducasse (Nature and Observability of Causal Relations [1926], §6) | |
| A reaction: A nice explanation of why, if causation is fundamentally about single instances, people seem so interested in generalisations and laws. We want to predict, and we want to explain, and we want to intervene. |
| 20705 | That events could be uncaused is absurd; I only say intuition and demonstration don't show this [Hume] |
| Full Idea: I never asserted so absurd a proposition as that anything might arise without a cause: I only maintained that our certainty of the falsehood of that proposition proceeded neither from intuition nor from demonstration, but from another source. | |
| From: David Hume (Letters [1739], 1754), quoted by Brian Davies - Introduction to the Philosophy of Religion 5 'God' | |
| A reaction: Since the other source is habit, he is being a bit disingenuous. While rational intuition and demonstration give a fairly secure basis for the universality of causation, mere human habits of expectation give very feeble grounds. |
