21406 | Because there is only one human reason, there can only be one true philosophy from principles [Kant] |
Full Idea: Considered objectively, there can only be one human reason, there cannot be many philosophies; in other words, there can only be one true philosophy from principles, in however many conflicting ways men have philosophised about the same proposition. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], Pref) | |
A reaction: An idea that embodies the Enlightenment ideal. I like the idea that there is one true philosophy, because there is only one world. Kant is talking of philosophy 'from principles', which means his transendental idealism. |
304 | Beautiful things must be different from beauty itself, but beauty itself must be present in each of them [Plato] |
Full Idea: Are fine things different from or identical to fineness? They are different from fineness itself, but fineness itself is in a sense present in each of them. | |
From: Plato (Euthydemus [c.379 BCE], 301a) |
16120 | Knowing how to achieve immortality is pointless without the knowledge how to use immortality [Plato] |
Full Idea: If there exists the knowledge of how to make men immortal, but without the knowledge of how to use this immortality, there seems to be no value in it. | |
From: Plato (Euthydemus [c.379 BCE], 289b) | |
A reaction: I take this to be not a gormless utilitarianism about knowledge, but a plea for holism, that knowledge only has value as part of some larger picture. The big view is the important view. He's wrong, though. Work out the use later. |
21081 | We are equipped with the a priori intuitions needed for the concept of right [Kant] |
Full Idea: Reason has taken care that the understanding is as fully equipped as possible with a priori intuitions for the construction of the concept of right. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], Intro E) | |
A reaction: A priori intuitions are not the same as innate knowledge or innate concepts, but they must require some sort of inbuilt inner resources. Further evidence that Kant is a rationalist philosopher (if we were unsure). |
303 | Say how many teeth the other has, then count them. If you are right, we will trust your other claims [Plato] |
Full Idea: If each of you says how many teeth the other has, and when they are counted we find you do know, we will believe your other claims as well. | |
From: Plato (Euthydemus [c.379 BCE], 294c) | |
A reaction: This is the clairvoyant problem for reliabilism, if truth is delivered for no apparent reason. Useful, but hardly knowledge. HOW did you know the number of teeth? |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
302 | What knowledge is required to live well? [Plato] |
Full Idea: What knowledge would enable us to live finely for the rest of our lives? | |
From: Plato (Euthydemus [c.379 BCE], 293a) | |
A reaction: A successful grasp of other people's points of view might lead to respect for them. Also a realisation that we are not isolated individuals. We really are all in it together. |
301 | Only knowledge of some sort is good [Plato] |
Full Idea: Nothing is good except knowledge of some sort. | |
From: Plato (Euthydemus [c.379 BCE], 292b) | |
A reaction: I've heard it suggested that truth is the only value. This is the Socratic idea that moral goodness is a matter of successful rational judgement. Not convinced, but interesting. |
305 | Something which lies midway between two evils is better than either of them [Plato] |
Full Idea: Something which is composed of two factors which are bad for different purposes and lies midway between them is better than either of the factors. | |
From: Plato (Euthydemus [c.379 BCE], 306a) |
21082 | A power-based state of nature may not be unjust, but there is no justice without competent judges [Kant] |
Full Idea: The state of nature need not be a state of injustice merely because those who live in it treat one another in terms of power. But it is devoid of justice, for if a dispute over right occurs in it, there is no competent judge to give valid decisions. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §44) | |
A reaction: Could you not achieve justice by means of personal violence? Might not a revered older person have been accepted as a judge? |
21089 | Monarchs have the highest power; autocrats have complete power [Kant] |
Full Idea: A monarch has the highest power, while an autocrat or absolute ruler is one who has all the power. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §51) | |
A reaction: If society is strictly hierarchical (like an army) then the monarch also has all the power. At the other extreme the one holding the highest power may have very little power, because so many others have their share of the power. |
21086 | Hereditary nobility has not been earned, and probably won't be earned [Kant] |
Full Idea: A hereditary nobility is a distinction bestowed before it is earned, and since it gives no ground for hoping that it will be earned, it is wholly unreal and fanciful. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §49 Gen D) | |
A reaction: As the controller of the region of a country, a hereditary noble is the embodiment of a ruling family, which is a well established way of running things. Daft, perhaps, but there are probably worse ways of doing it. Single combat, for example. |
21080 | Actions are right if the maxim respects universal mutual freedoms [Kant] |
Full Idea: Every action which by itself or by its maxim enables the freedom of each individual's will to co-exist with the freedom of everyone else in accordance with a universal law is right. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], Intro C) | |
A reaction: This idea shows the moral basis for Kant's liberalism in politics. If all individuals acted without contact or reference to other individuals (a race of hermits) then that would appear to be optimum moral right, by this standard. |
21083 | Women have no role in politics [Kant] |
Full Idea: Women in general …have no civil personality. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §46) | |
A reaction: In case you were wondering. This is five years after Mary Wollstonecraft's book. |
21407 | Equality is not being bound in ways you cannot bind others [Kant] |
Full Idea: Our innate equality is independence from being bound by others to more than one can in turn bind them. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], Div B) | |
A reaction: This doesn't seem to capture the whole concept. The two of us may be unequally oppressed by a third. We are unequal with the third, but also with one another, though with no binding relationships. |
21084 | In the contract people lose their rights, but immediately regain them, in the new commonwealth [Kant] |
Full Idea: By the original contract all members of the people give up their external freedom in order to receive it back at once as members of a commonweath. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §47) | |
A reaction: This tries to give the impression that absolutely nothing is lost in the original alienation of rights. It is probably better to say that you give up one set of freedoms, which are replaced by a different (and presumably superior) set. |
21090 | If someone has largely made something, then they own it [Kant] |
Full Idea: Whatever someone has himself substantially made is his own undisputed property. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §55) | |
A reaction: To this extent Kant offers clear agreement with Locke about a self-evident property right. Ownership of land is the controversial bit. |
21087 | Human life is pointless without justice [Kant] |
Full Idea: If justice perishes, there is no further point in men living on earth. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §49 Gen E) | |
A reaction: I suspect that human life is also pointless if it only involves justice, and nothing else worthwhile. Are there other things so good that we might sacrifice justice to achieve them? How about maximal utilitarian happiness? |
21088 | Justice asserts the death penalty for murder, from a priori laws [Kant] |
Full Idea: All murderers …must suffer the death penalty. This is what justice, as the idea of judicial power, wills in accordance with universal laws of a priori origin. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §49 Gen E) | |
A reaction: Illustration of how giving a principle an a priori origin puts it beyond dispute. Kant is adamant that mercy mustn't interfere with the enactment of justice. And Kant obviously rejects any consequentialist approach. Remind me what is wrong with murder? |
21085 | The church has a political role, by offering a supreme power over people [Kant] |
Full Idea: The church [as opposed to religion] fulfils a genuine political necessity, for it enables the people to regard themselves as subjects of an invisible supreme power to which they must pay homage. | |
From: Immanuel Kant (Metaphysics of Morals I: Doctrine of Right [1797], §49 Gen C) | |
A reaction: I'm sure I remember Marx putting a different spin on this point… This idea captures the conservative attitude to established religion, at least in the UK. |
