| 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. |
| 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). |
| 7658 | Obviously there can't be a functional anaylsis of qualia if they are defined by intrinsic properties [Dennett] |
| Full Idea: If you define qualia as intrinsic properties of experiences considered in isolation from all their causes and effects, logically independent of all dispositional properties, then they are logically guaranteed to elude all broad functional analysis. | |
| From: Daniel C. Dennett (Sweet Dreams [2005], Ch.8) | |
| A reaction: This is a good point - it seems daft to reify qualia and imagine them dangling in mid-air with all their vibrant qualities - but that is a long way from saying there is nothing more to qualia than functional roles. Functions must be exlained too. |
| 7655 | The work done by the 'homunculus in the theatre' must be spread amongst non-conscious agencies [Dennett] |
| Full Idea: All the work done by the imagined homunculus in the Cartesian Theater must be distributed among various lesser agencies in the brain, none of which is conscious. | |
| From: Daniel C. Dennett (Sweet Dreams [2005], Ch.3) | |
| A reaction: Dennett's account crucially depends on consciousness being much more fragmentary than most philosophers claim it to be. It is actually full of joints, which can come apart. He may be right. |
| 7657 | Intelligent agents are composed of nested homunculi, of decreasing intelligence, ending in machines [Dennett] |
| Full Idea: As long as your homunculi are more stupid and ignorant than the intelligent agent they compose, the nesting of homunculi within homunculi can be finite, bottoming out, eventually, with agents so unimpressive they can be replaced by machines. | |
| From: Daniel C. Dennett (Sweet Dreams [2005], Ch.6) | |
| A reaction: [Dennett first proposed this in 'Brainstorms' 1978]. This view was developed well by Lycan. I rate it as one of the most illuminating ideas in the modern philosophy of mind. All complex systems (like aeroplanes) have this structure. |
| 7656 | I don't deny consciousness; it just isn't what people think it is [Dennett] |
| Full Idea: I don't maintain, of course, that human consciousness does not exist; I maintain that it is not what people often think it is. | |
| From: Daniel C. Dennett (Sweet Dreams [2005], Ch.3) | |
| A reaction: I consider Dennett to be as near as you can get to an eliminativist, but he is not stupid. As far as I can see, the modern philosopher's bogey-man, the true total eliminativist, simply doesn't exist. Eliminativists usually deny propositional attitudes. |
| 7654 | What matters about neuro-science is the discovery of the functional role of the chemistry [Dennett] |
| Full Idea: Neuro-science matters because - and only because - we have discovered that the many different neuromodulators and other chemical messengers that diffuse throughout the brain have functional roles that make important differences. | |
| From: Daniel C. Dennett (Sweet Dreams [2005], Ch.1) | |
| A reaction: I agree with Dennett that this is the true ground for pessimism about spectacular breakthroughs in artificial intelligence, rather than abstract concerns about irreducible features of the mind like 'qualia' and 'rationality'. |
| 13965 | Semantics as theory of meaning and semantics as truth-based logical consequence are very different [Soames] |
| Full Idea: There are two senses of 'semantic' - as theory of meaning or as truth-based theory of logical consequence, and they are very different. | |
| From: Scott Soames (Why Propositions Aren't Truth-Supporting Circumstance [2008], p.78) | |
| A reaction: This subtle point is significant in considering the role of logic in philosophy. The logicians' semantics (based on logical consequence) is in danger of ousting the broader and more elusive notion of meaning in natural language. |
| 13964 | Semantic content is a proposition made of sentence constituents (not some set of circumstances) [Soames] |
| Full Idea: The semantic content of a sentence is not the set of circumstances supporting its truth. It is rather the semantic content of a structured proposition the constituents of which are the semantic contents of the constituents of the sentence. | |
| From: Scott Soames (Why Propositions Aren't Truth-Supporting Circumstance [2008], p.74) | |
| A reaction: I'm not sure I get this, but while I like the truth-conditions view, I am suspicious of any proposal that the semantic content of something is some actual physical ingredients of the world. Meanings aren't sticks and stones. |
| 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. |
