23367 | Even pointing a finger should only be done for a reason [Epictetus] |
Full Idea: Philosophy says it is not right even to stretch out a finger without some reason. | |
From: Epictetus (fragments/reports [c.57], 15) | |
A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!). |
6950 | You can be rational with undetected or minor inconsistencies [Harman] |
Full Idea: Rationality doesn't require consistency, because you can be rational despite undetected inconsistencies in beliefs, and it isn't always rational to respond to a discovery of inconsistency by dropping everything in favour of eliminating that inconsistency. | |
From: Gilbert Harman (Rationality [1995], 1.2) | |
A reaction: This strikes me as being correct, and is (I am beginning to realise) a vital contribution made to our understanding by pragmatism. European thinking has been too keen on logic as the model of good reasoning. |
20955 | Art can make reason more all-inclusive, by articulating what seemed inexpressible [Bowie] |
Full Idea: The early German Romantics argued that art pointed to a more all-inclusive conception of reason, which can offer ways of articulating what is not conceptually accessible. | |
From: Andrew Bowie (Introduction to German Philosophy [2003], 5 'Reason') | |
A reaction: [This is Novalis, F.Schlegel, Schleiermacher, and Hölderlin] I'm in favour of expanding reason, to include assessment of situations and coherence, rather than just stepwise reasoning. Not sure that art 'articulates' something new. |
6954 | A coherent conceptual scheme contains best explanations of most of your beliefs [Harman] |
Full Idea: A set of unrelated beliefs seems less coherent than a tightly organized conceptual scheme that contains explanatory principles that make sense of most of your beliefs; this is why inference to the best explanation is an attractive pattern of inference. | |
From: Gilbert Harman (Rationality [1995], 1.5.2) | |
A reaction: I find this a very appealing proposal. The central aim of rational thought seems to me to be best explanation, and I increasingly think that most of my beliefs rest on their apparent coherence, rather than their foundations. |
20950 | German Idealism says our thinking and nature have the same rational structure [Bowie] |
Full Idea: German Idealism aims to demonstrate that our thinking relates to a nature which is intelligibly structured in the same way as our thinking is structured. | |
From: Andrew Bowie (Introduction to German Philosophy [2003], 3 'Limits') | |
A reaction: Now that's an idealism I might buy into. Frege thought his logic was mapping rational reality. My angle is that we are a product of this 'reality', so we should expect our thinking to be similarly structured. Reason is derived from nature. |
6955 | Enumerative induction is inference to the best explanation [Harman] |
Full Idea: We might think of enumerative induction as inference to the best explanation, taking the generalization to explain its instances. | |
From: Gilbert Harman (Rationality [1995], 1.5.2) | |
A reaction: This is a helpful connection. The best explanation of these swans being white is that all swans are white; it ceased to be the best explanation when black swans turned up. In the ultimate case, a law of nature is the explanation. |
6952 | Induction is 'defeasible', since additional information can invalidate it [Harman] |
Full Idea: It is sometimes said that inductive reasoning is 'defeasible', meaning that considerations that support a given conclusion can be defeated by additional information. | |
From: Gilbert Harman (Rationality [1995], 1.4.5) | |
A reaction: True. The point is that being defeasible does not prevent such thinking from being rational. The rational part of it is to acknowledge that your conclusion is defeasible. |
6953 | All reasoning is inductive, and deduction only concerns implication [Harman] |
Full Idea: Deductive logic is concerned with deductive implication, not deductive reasoning; all reasoning is inductive | |
From: Gilbert Harman (Rationality [1995], 1.4.5) | |
A reaction: This may be an attempt to stipulate how the word 'reasoning' should be used in future. It is, though, a bold and interesting claim, given the reputation of induction (since Hume) of being a totally irrational process. |
20942 | Nazis think race predetermines the self [Bowie] |
Full Idea: The Nazi idea is that the self is predetermined primarily by its race. | |
From: Andrew Bowie (Introduction to German Philosophy [2003], Intro) | |
A reaction: I suspect that I occasionally encounter this view, in very patriotic people. But then you meet people who feeling that their self is mainly determined by support of a football team. Note, though, 'pre-'determined. Hegel makes this idea possible? |
6951 | Ordinary rationality is conservative, starting from where your beliefs currently are [Harman] |
Full Idea: Ordinary rationality is generally conservative, in the sense that you start from where you are, with your present beliefs and intentions. | |
From: Gilbert Harman (Rationality [1995], 1.3) | |
A reaction: This stands opposed to the Cartesian or philosophers' rationality, which requires that (where possible) everything be proved from scratch. Harman seems right, that the normal onus of proof is on changing beliefs, rather proving you should retain them. |
20946 | Rhetoric is built into language, so it cannot be stripped from philosophy [Bowie] |
Full Idea: The attempt to rid philosophy of rhetoric falls prey precisely to that fact that what is involved in rhetoric is inherent in what is built into all natural languages by their genesis in the real historical world. | |
From: Andrew Bowie (Introduction to German Philosophy [2003], 2 'Hamann') | |
A reaction: Rhetoric can range from charming to bullying, and it is the latter which is the problem. The underlying issue is dogma versus dialectic. Some analytic philosophers have a good shot at being non-rhetorical. |
