7426 | Critical philosophy is what questions domination at every level [Foucault] |
Full Idea: In its critical aspect, philosophy is that which calls into question domination at every level | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.300) | |
A reaction: A very French view of the subject. It is tempting to say that they had their adolescent outburst in 1789, and it is time to grow up. With rights come responsibilities... |
7423 | Philosophy and politics are fundamentally linked [Foucault] |
Full Idea: The relationship between philosophy and politics is permanent and fundamental. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.293) | |
A reaction: This idea is one of the biggest gulfs between continental and analytical philosophy. Many aspects of philosophy are turning out to be much more social than analytical philosophers might have thought - epistemology, for example. |
7420 | When logos controls our desires, we have actually become the logos [Foucault] |
Full Idea: Plutarch says if you have mastered principles then logos will silence your desires like a master silencing a dog - in which case the logos functions without intervention on your part - you have become the logos, or the logos has become you. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.286) | |
A reaction: If you believe that logos is pure reason, you might be quite happy with this, but if you thought it was a cultural construct, you might feel that you had been cunningly enslaved. If I ask 'what is 7+6?', logos interrupts me to give the answer. |
13338 | '"It is snowing" is true if and only if it is snowing' is a partial definition of the concept of truth [Tarski] |
Full Idea: Statements of the form '"it is snowing" is true if and only if it is snowing' and '"the world war will begin in 1963" is true if and only if the world war will being in 1963' can be regarded as partial definitions of the concept of truth. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.404) | |
A reaction: The key word here is 'partial'. Truth is defined, presumably, when every such translation from the object language has been articulated, which is presumably impossible, given the infinity of concatenated phrases possible in a sentence. |
13337 | A language: primitive terms, then definition rules, then sentences, then axioms, and finally inference rules [Tarski] |
Full Idea: For a language, we must enumerate the primitive terms, and the rules of definition for new terms. Then we must distinguish the sentences, and separate out the axioms from amng them, and finally add rules of inference. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.402) | |
A reaction: [compressed] This lays down the standard modern procedure for defining a logical language. Once all of this is in place, we then add a semantics and we are in business. Natural deduction tries to do without the axioms. |
13335 | Semantics is the concepts of connections of language to reality, such as denotation, definition and truth [Tarski] |
Full Idea: Semantics is the totality of considerations concerning concepts which express connections between expressions of a language and objects and states of affairs referred to by these expressions. Examples are denotation, satisfaction, definition and truth. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.401) | |
A reaction: Interestingly, he notes that it 'is not commonly recognised' that truth is part of semantics. Nowadays truth seems to be the central concept in most semantics. |
13336 | A language containing its own semantics is inconsistent - but we can use a second language [Tarski] |
Full Idea: People have not been aware that the language about which we speak need by no means coincide with the language in which we speak. ..But the language which contains its own semantics must inevitably be inconsistent. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.402) | |
A reaction: It seems that Tarski was driven to propose the metalanguage approach mainly by the Liar Paradox. |
13339 | A sentence is satisfied when we can assert the sentence when the variables are assigned [Tarski] |
Full Idea: Here is a partial definition of the concept of satisfaction: John and Peter satisfy the sentential function 'X and Y are brothers' if and only if John and Peter are brothers. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.405) | |
A reaction: Satisfaction applies to open sentences and truth to closed sentences (with named objects). He uses the notion of total satisfaction to define truth. The example is a partial definition, not just an illustration. |
13340 | Satisfaction is the easiest semantical concept to define, and the others will reduce to it [Tarski] |
Full Idea: It has been found useful in defining semantical concepts to deal first with the concept of satisfaction; both because the definition of this concept presents relatively few difficulties, and because the other semantical concepts are easily reduced to it. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.406) | |
A reaction: See Idea 13339 for his explanation of satisfaction. We just say that a open sentence is 'acceptable' or 'assertible' (or even 'true') when particular values are assigned to the variables. Then sentence is then 'satisfied'. |
13341 | Using the definition of truth, we can prove theories consistent within sound logics [Tarski] |
Full Idea: Using the definition of truth we are in a position to carry out the proof of consistency for deductive theories in which only (materially) true sentences are (formally) provable. | |
From: Alfred Tarski (The Establishment of Scientific Semantics [1936], p.407) | |
A reaction: This is evidently what Tarski saw as the most important first fruit of his new semantic theory of truth. |
7424 | Saying games of truth were merely power relations would be a horrible exaggeration [Foucault] |
Full Idea: When I talk about power relations and games of truth, I am absolutely not saying that games of truth are just concealed power relations - that would be a horrible exaggeration. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.296) | |
A reaction: I take this to be a denial of the more absurd forms of relativism. I think there is an interesting convergence between this kind of continental thinking, and the social view of justification found in the later work of Alvin Goldman. |
7422 | A subject is a form which can change, in (say) political or sexual situations [Foucault] |
Full Idea: The subject is not a substance but a form, which is not always identical to itself. You do not have the same relation to yourself when you go to vote and when you seek to fulfil your desires in a sexual relationship. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.290) | |
A reaction: I don't think I believe this. If it were true, the concept of 'sexual politics' would mean nothing to me. A brutal or sympathetic nature is likely to express itself in both situations. |
7419 | Ethics is the conscious practice of freedom [Foucault] |
Full Idea: What is ethics, if not the practice of freedom, the conscious [réfléchie] practice of freedom? | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.284) | |
A reaction: Makes Foucault sound very existentialist. I'm not sure I understand this kind of remark, given that serial killers seem to be exceptionally good at 'practising their freedom'. However, the idea is akin to Kant's notion of a truly good will (Idea 3710). |
7425 | The aim is not to eliminate power relations, but to reduce domination [Foucault] |
Full Idea: The problem is not to dissolve power relations in a utopia of transparent communications, but to acquire the rules of law, the management techniques, the morality, the practice of the self, that allows games of power with minimum domination. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.298) | |
A reaction: If you are a democrat it is hard to disagree with this, though I am still unclear why being dominated should rank as a total disaster. A healthy personal relationship might involve domination. 'Management techniques' is interesting. |
7418 | The idea of liberation suggests there is a human nature which has been repressed [Foucault] |
Full Idea: I am somewhat suspicious of the notion of liberation, because one runs the risk of falling back on the idea that there is a human nature, that has been concealed or alienated by mechanisms of repression. | |
From: Michel Foucault (Ethics of the Concern for Self as Freedom [1984], p.282) | |
A reaction: Personally I think there is (to some extent) a human nature, and that it fails to flourish if it gets too much 'liberation. However, the world contains a lot more repression than liberation, so we should all be fans of liberty. |
13304 | Learned men gain more in one day than others do in a lifetime [Posidonius] |
Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes. | |
From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078 | |
A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book. |
20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
