12900 | How could 'S knows he has hands' not have a fixed content? [Bach] |
Full Idea: How can it be that a sentence like 'George knows that he has hands', even with time and references fixed, does not have a fixed propositional content? | |
From: Kent Bach (The Emperor's New 'Knows' [2005], I) | |
A reaction: The appeal is to G.E. Moore's common sense view of immediate knowledge (Idea 6349). The reply is simply that the word 'knows' shifts its meaning, having high standards in sceptical philosophy classes, and low standards on the street. |
12901 | If contextualism is right, knowledge sentences are baffling out of their context [Bach] |
Full Idea: Contextualism seems to predict that if you encounter a knowledge attribution out of context you won't be in a position to grasp which proposition the sentence expresses. | |
From: Kent Bach (The Emperor's New 'Knows' [2005], I) | |
A reaction: It is only the word 'knows' which is at issue in the sentence. If someone is said to 'know' about the world of the fairies, we might well be puzzled as to what proposition was being expressed. Is the word 'flat' baffling out of context? |
12902 | Sceptics aren't changing the meaning of 'know', but claiming knowing is tougher than we think [Bach] |
Full Idea: When a sceptic brings up far-fetched possibilities and argues that we can't rule them out, he is not raising the standard for the word 'know'. He is showing it is tougher than we realise for a belief to qualify as normal knowledge at all. | |
From: Kent Bach (The Emperor's New 'Knows' [2005], III) | |
A reaction: [Bach cites Richard Feldman for this idea] I think that what happens in the contextual account is that 'true', 'belief' and 'know' retain their standard meaning, and it is 'justified' which shifts. 'I am fully justified' can have VERY different meanings! |
3785 | You can't separate acts from the people performing them [Glover] |
Full Idea: A mistake of consequentialists is to treat actions as though they can somehow be isolated from the people performing them. | |
From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five) | |
A reaction: I agree. The weather produces consequences. Morality is about people. Crocodiles, for example, are exempt. |
3786 | Aggression in defence may be beneficial but morally corrupting [Glover] |
Full Idea: Forming the intention to use nuclear retaliation if attacked may both be the best way to avoid the catastrophe of nuclear war and at the same time be morally corrupting. | |
From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five) | |
A reaction: A famous moment in 2017 when Jeremy Corbyn refused to say he would be willing to use the weapons, if elected. It would be hard to sustain a determination to do it, and then reject it at the crucial moment. |
3784 | Duty prohibits some acts, whatever their consequences [Glover] |
Full Idea: The deontological view is that some acts are absolutely prohibited, regardless of consequences. | |
From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Five) |
3782 | Satisfaction of desires is not at all the same as achieving happiness [Glover, by PG] |
Full Idea: Objections to utilitarianism as maximisation of preferences: faded past desires or the desires of the dead; obtaining desires and happiness are different; fewer desires are easier to satisfy; pain is good if it can be removed. | |
From: report of Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Two) by PG - Db (ideas) |
3787 | Rule-utilitarianism is either act-utilitarianism, or not really utilitarian [Glover] |
Full Idea: Rule-utilitarianism seems either to collapse into act-utilitarianism, or else it is only partly utilitarian. | |
From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Six) |
3783 | How can utilitarianism decide the ideal population size? [Glover] |
Full Idea: There are deep problems for utilitarianism in trying to work out what the ideal population size would be. | |
From: Jonathan Glover (Introductions to Utilitarianism and its Critics [1990], Pt Four) |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
