16 ideas
| 19396 | Wisdom is knowing all of the sciences, and their application [Leibniz] |
| Full Idea: Wisdom is a perfect knowledge of the principles of all the sciences and of the art of applying them. | |
| From: Gottfried Leibniz (On Wisdom [1693], 0) | |
| A reaction: 'Sciences' should be understood fairly broadly here (e.g. of architecture, agriculture, grammar). This is a scholar's vision of wisdom, very different from the notion of the wisest person in a village full of illiterate people. |
| 12036 | Xenophanes began the concern with knowledge [Annas] |
| Full Idea: Xenophanes begins a long concern with knowledge and its grounds. | |
| From: Julia Annas (Ancient Philosophy: very short introduction [2000], Intro) | |
| A reaction: Having that on his cv ought to make Xenophanes more famous than he is. |
| 12046 | Plato was the first philosopher who was concerned to systematize his ideas [Annas] |
| Full Idea: In the ancient world Plato was seen as a pivotal figure, the first philosopher who was concerned to systematize his ideas. | |
| From: Julia Annas (Ancient Philosophy: very short introduction [2000], Ch.6) |
| 19397 | Perfect knowledge implies complete explanations and perfect prediction [Leibniz] |
| Full Idea: The mark of perfect knowledge is that nothing appears in the thing under consideration which cannot be accounted for, and that nothing is encountered whose occurrence cannot be predicted in advance. | |
| From: Gottfried Leibniz (On Wisdom [1693], 1) | |
| A reaction: I would track both of these back to the concept of perfect understanding, which is admittedly a bit vague. Does a finite mind need to predict every speck of dust to have perfect knowledge? Do we have perfect knowledge of triangles? |
| 12037 | Euripides's Medea is a key case of reason versus the passions [Annas] |
| Full Idea: Euripides's Medea has remained a key case for discussion of reason and the passions. | |
| From: Julia Annas (Ancient Philosophy: very short introduction [2000], Ch.1) |
| 12040 | Virtue is a kind of understanding of moral value [Annas] |
| Full Idea: There is a widespread view in ancient ethics that virtue is a kind of understanding of moral value. | |
| From: Julia Annas (Ancient Philosophy: very short introduction [2000], Ch.3) | |
| A reaction: In Aristotle's case, this coincides with his apparent view that 'understanding' is the aim of all areas of human thought. See Idea 12038. |
| 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? |
