9 ideas
2986 | Belief is the most important propositional attitude [Lyons] |
Full Idea: Belief might be accorded the status of core or chief propositional attitude. | |
From: William Lyons (Approaches to Intentionality [1995], p.126) |
11052 | Psychological logic can't distinguish justification from causes of a belief [Frege] |
Full Idea: With the psychological conception of logic we lose the distinction between the grounds that justify a conviction and the causes that actually produce it. | |
From: Gottlob Frege (Logic [1897] [1897]) | |
A reaction: Thus Frege kicked the causal theory of justification well into touch long before it had even been properly formulated. That is not to say that there is no psychological aspect to logic, because there is. |
2978 | Consciousness no longer seems essential to intentionality [Lyons] |
Full Idea: In contrast with Brentano and Husserl, consciousness or attention are no longer seen as essential to intentionality. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: This strikes me as being correct, although there seem to be plenty of current philosophers who do not accept it (e.g. Searle). I think philosophy of mind may be stuck in the dark ages if thinkers don't accept this proposal. |
2984 | Perceptions could give us information without symbolic representation [Lyons] |
Full Idea: It is possible to give an account of concept-formation without a language of thought or representation, based on perception, which in the brain seems to involve information without representation. | |
From: William Lyons (Approaches to Intentionality [1995], p.66) | |
A reaction: This claim strikes me as being a little too confident. One might say that a concept IS a representation. However, the perception of several horses might 'blur' together to form a generalised horse. |
2979 | Propositional attitudes require representation [Lyons] |
Full Idea: How else, other than via some form of representational system, could a human organism contain information as a content over which it could operate or 'attitudinise'? | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Depends what you mean by 'representational'. In its vaguest sense, this is just a tautology - content must be held in the mind in some form or other, but that tells us nothing. |
2987 | Folk psychology works badly for alien cultures [Lyons] |
Full Idea: It is not easy to employ our folk psychology in the understanding of persons in a very different culture. | |
From: William Lyons (Approaches to Intentionality [1995], p.241) | |
A reaction: This strikes me as a highly significant problem for the friends of folk psychology. It also breaks down in extreme situations, or with mental illness. It seems closer to culture than to brain structure. |
2977 | All thinking has content [Lyons] |
Full Idea: I cannot say I am simply thinking but not thinking about anything. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Hard to disagree. However, I can plausibly reply to 'What are you thinking?' with 'Nothing', if my consciousness is freewheeling. Utterly disconnected content isn't really what we call 'thinking'. |
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. |
