20 ideas
| 23531 | Philosophers should interpret the world, by expressing its possibilities [Berardi] |
| Full Idea: The philosopher's task is to interpret the world, that is, to capture its tendency and above all to enunciate the possibilities inscribed therein. …The politician's eye does not see the possible, being attracted instead by the probable. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], How to) | |
| A reaction: An inspiring idea! He is rejecting Marx's aim of changing the world, which had 'catastrophic' results. But I love his view of interpretation as spotting tendencies and possibilities. This fits my preferred ontology of dispositions and powers. |
| 8952 | We reach 'reflective equilibrium' when intuitions and theory completely align [Fisher] |
| Full Idea: A state of 'reflective equilibrium' is when our theory and our intuitions become completely aligned | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.IV) | |
| A reaction: [Rawls made this concept famous] This is a helpful concept in trying to spell out the ideal which is the dream of believers in 'pure reason' - that there is a goal in which everything comes right. The problem is when people have different intuitions! |
| 8943 | Three-valued logic says excluded middle and non-contradition are not tautologies [Fisher] |
| Full Idea: In three-valued logic (L3), neither the law of excluded middle (p or not-p), nor the law of non-contradiction (not(p and not-p)) will be tautologies. If p has the value 'indeterminate' then so will not-p. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.I) | |
| A reaction: I quite accept that the world is full of indeterminate propositions, and that excluded middle and non-contradiction can sometimes be uncertain, but I am reluctant to accept that what is being offered here should be called 'logic'. |
| 8945 | Fuzzy logic has many truth values, ranging in fractions from 0 to 1 [Fisher] |
| Full Idea: In fuzzy logic objects have properties to a greater or lesser degree, and truth values are given as fractions or decimals, ranging from 0 to 1. Not-p is defined as 1-p, and other formula are defined in terms of maxima and minima for sets. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The question seems to be whether this is actually logic, or a recasting of probability theory. Susan Haack attacks it. If logic is the study of how truth is preserved as we move between propositions, then 0 and 1 need a special status. |
| 8951 | Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism [Fisher] |
| Full Idea: For simplicity, we can say that 'classical logic' amounts to the truth of four sentences: 1) either p or not-p; 2) it is not the case that both p and not-p; 3) from p and not-p, infer q; 4) from p or q and not-p, infer q. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 12.I) | |
| A reaction: [She says there are many ways of specifying classical logic] Intuition suggests that 2 and 4 are rather hard to dispute, while 1 is ignoring some grey areas, and 3 is totally ridiculous. There is, of course, plenty of support for 3! |
| 8950 | Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher] |
| Full Idea: Even if one is inclined to be a realist about everything, it is hard to see why our logic should be the determiner. Logic is supposed to formalize how we ought to reason, but whether or not we should be realists is a matter of philosophy, not logic. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 09.I) | |
| A reaction: Nice to hear a logician saying this. I do not see why talk in terms of an object is a commitment to its existence. We can discuss the philosopher's stone, or Arthur's sword, or the Loch Ness monster, or gravitinos, with degrees of commitment. |
| 23538 | Nothingness only exists in consciousness [Berardi] |
| Full Idea: Consciousness is the only place where nothingness exists. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], II 'Expanding') | |
| A reaction: Not sure about this, but an interesting remark from someone with a Hegelian background. We certainly have a concept of nothingness (a mental file of it, even). |
| 16007 | I assume existence, rather than reasoning towards it [Kierkegaard] |
| Full Idea: I always reason from existence, not towards existence. | |
| From: Søren Kierkegaard (Philosophical Fragments [1844], p.40) | |
| A reaction: Kierkegaard's important premise to help show that theistic proofs for God's existence don't actually prove existence, but develop the content of a conception. [SY] |
| 8946 | We could make our intuitions about heaps precise with a million-valued logic [Fisher] |
| Full Idea: We could construct a 1,000,000-valued logic that would allow our intuitions concerning a heap to vary exactly with the amount of sand in the heap. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008]) | |
| A reaction: Presumably only an infinite number of grains of sand would then produce a true heap, and even one grain would count as a bit of a heap, which must both be wrong, so I can't see this helping much. |
| 8944 | Vagueness can involve components (like baldness), or not (like boredom) [Fisher] |
| Full Idea: Vague terms come in at least two different kinds: those whose constituent parts come in discrete packets (bald, rich, red) and those that don't (beauty, boredom, niceness). | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 07.II) | |
| A reaction: The first group seem to be features of the external world, and the second all occur in the mind. Baldness may be vague, but presumably hairs are (on the whole) not. Nature doesn't care whether someone is actually 'bald' or not. |
| 16013 | Nothing necessary can come into existence, since it already 'is' [Kierkegaard] |
| Full Idea: Can the necessary come into existence? That is a change, and everything that comes into existence demonstrates that it is not necessary. The necessary already 'is'. | |
| From: Søren Kierkegaard (Philosophical Fragments [1844], p.74) | |
| A reaction: [SY] |
| 8941 | We can't explain 'possibility' in terms of 'possible' worlds [Fisher] |
| Full Idea: Explaining 'it is possible that p' by saying p is true in at least one possible world doesn't get me very far. If I don't understand what possibility is, then appealing to possible worlds is not going to do me much good. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 06.III) | |
| A reaction: This seems so blatant that I assume friends of possible worlds will have addressed the problem. Note that you will also need to understand 'possible' to define necessity as 'true in all possible worlds'. Necessarily-p is not-possibly-not-p. |
| 8947 | If all truths are implied by a falsehood, then not-p might imply both q and not-q [Fisher] |
| Full Idea: If all truths are implied by a falsehood, then 'if there are no trees in the park then there is no shade' and 'if there are no trees in the park there is plenty of shade' both come out as true. Intuitively, though, the second one is false. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.I) | |
| A reaction: The rule that a falsehood implies all truths must be the weakest idea in classical logic, if it actually implies a contradiction. This means we must take an interest in relevance logics. |
| 8949 | In relevance logic, conditionals help information to flow from antecedent to consequent [Fisher] |
| Full Idea: A good account of relevance logic suggests that a conditional will be true when the flow of information is such that a conditional is the device that helps information to flow from the antecedent to the consequent. | |
| From: Jennifer Fisher (On the Philosophy of Logic [2008], 08.III) | |
| A reaction: Hm. 'If you are going out, you'll need an umbrella'. This passes on information about 'out', but also brings in new information. 'If you are going out, I'm leaving you'. What flows is an interpretation of the antecedent. Tricky. |
| 23532 | The delusion of free will brings a sense of guilt [Berardi] |
| Full Idea: A sense of guilt is linked to the delusion of free will. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], How to) | |
| A reaction: I agree that free will is a delusion, but I'm not sure about this. Clearly if you think you are 'ultimately' responsible for all of your actions this will increase guilt, but belief in free will is compatible with various excuses for actions. |
| 23537 | American white men trusted the philosophy of winning, and then discovered losing [Berardi] |
| Full Idea: American white men trusted the promises of neoliberal selfishness, they trusted the philosophy of winning, then discovered losing. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], I 'Fascism') | |
| A reaction: The most pernicious terminology in the English-speaking world is the labelling of people as 'winners' and 'losers'. We celebrate the one winner, and ignore everyone else. Celebrity, excessive wealth, honourable titles. |
| 23536 | Community is now a nostalgic memory, which no longer exists [Berardi] |
| Full Idea: Community is only a nostalgic memory of a past condition of belonging that exists no longer. Regret, not a living experience. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], I 'Fascism') | |
| A reaction: It is hard to disagree with this. Local heroes in my town make lovely efforts to improve the place (with flowers, sculptures) but most of us don't know who they are. Capitalist competition erodes community. |
| 23534 | Communism failed to unite western workers with the oppressed of the south [Berardi] |
| Full Idea: Communist internationalism was the only attempt to reconcile the workers of the West and the oppressed population of the Global South, and this attempt failed. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], I 'Hundred') | |
| A reaction: It was unfortunate that communism was launched in Russia, which we now see (in 2023) as poisoned by imperialist ambitions, and quite unsuited to international idealism. The Chinese are notably active in Africa. |
| 23533 | The economy has replaced medieval theocracy at the centre of our society [Berardi] |
| Full Idea: The economy has progressively acquired the central place in the system of knowledge and research. Re-enacting the privilege of theocracy in the Middle Ages. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], I 'Knowledge') | |
| A reaction: Illuminating. This is indeed how the economy is treated, centring on Gross National Product (no matter how distributed), and economic league tables. Is it even a quasi-religion? |
| 23535 | Western workers turn to nationalism, to avert the effects of globalisation [Berardi] |
| Full Idea: Western workers are following nationalist agendas in order to avert the effects of globalization, and resorting to nationalist and racist forms of identification. | |
| From: Franco 'Bifo' Berardi (The Second Coming [2019], I 'Hundred') | |
| A reaction: By 'globalisation' must be meant the impersonal work and exploitation that results from huge ruthless anonymous companies. People barely know who they are working for, so it can't give them an identity. |
