If objects are just presentation, we get increasing abstraction by ignoring their properties [Frege]
|
|
Full Idea:
If an object is just presentation, we can pay less attention to a property and it disappears. By letting one characteristic after another disappear, we obtain concepts that are increasingly more abstract.
|
|
From:
Gottlob Frege (Review of Husserl's 'Phil of Arithmetic' [1894], p.324)
|
|
A reaction:
Frege despises this view. Note there is scope in the despised view for degrees or levels of abstraction, defined in terms of number of properties ignored. Part of Frege's criticism is realist. He retains the object, while Husserl imagines it different.

Many people have the same thought, which is the component, not the private presentation [Frege]
|
|
Full Idea:
The same thought can be grasped by many people. The components of a thought, and even more so the things themselves, must be distinguished from the presentations which in the soul accompany the grasping of a thought.
|
|
From:
Gottlob Frege (Review of Husserl's 'Phil of Arithmetic' [1894], p.325)
|
|
A reaction:
This is the basic realisation, also found in Russell, of how so much confusion has crept into philosophy, in Berkeley, for example. Frege starts down the road which leads to the externalist view of content.

Disregarding properties of two cats still leaves different objects, but what is now the difference? [Frege]
|
|
Full Idea:
If from a black cat and a white cat we disregard colour, then posture, then location, ..we finally derive something which is completely without restrictions on content; but what is derived from the objects does differ, although it is not easy to say how.
|
|
From:
Gottlob Frege (Review of Husserl's 'Phil of Arithmetic' [1894], p.324)
|
|
A reaction:
This is a key objection to abstractionism for Frege - we are counting two cats, not two substrata of essential catness, or whatever. But what makes a cat countable? (Key question!) It isn't its colour, or posture or location.

How do you find the right level of inattention; you eliminate too many or too few characteristics [Frege]
|
|
Full Idea:
Inattention is a very strong lye which must not be too concentrated, or it dissolves everything (such as the connection between the objects), but must not be too weak, to produce sufficient change. Personally I cannot find the proper dilution.
|
|
From:
Gottlob Frege (Review of Husserl's 'Phil of Arithmetic' [1894], p.330)
|
|
A reaction:
We may sympathise with the lack of precision here (frustrating for a logician), but it is not difficult to say of a baseball defence 'just concentrate on the relations, and ignore the individuals who implement it'. You retain basic baseball skills.

Psychological logicians are concerned with sense of words, but mathematicians study the reference [Frege]
|
|
Full Idea:
The psychological logicians are concerned with the sense of the words and with the presentations, which they do not distinguish from the sense; but the mathematicians are concerned with the matter itself, with the reference of the words.
|
|
From:
Gottlob Frege (Review of Husserl's 'Phil of Arithmetic' [1894], p.326)
|
|
A reaction:
This is helpful for showing the point of his sense/reference distinction; it is part of his campaign against psychologism, by showing that there is a non-psychological component to language - the reference, where it meets the public world.

Actions include: the involuntary, the purposeful, the intentional, and the self-consciously autonomous [Wilson/Schpall]
|
|
Full Idea:
There are different levels of action, including at least: unconscious and/or involuntary behaviour, purposeful or goal-directed activity, intentional action, and the autonomous acts or actions of self-consciously active human agents.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 1)
|
|
A reaction:
The fourth class is obviously designed to distinguish us from the other animals. It immediately strikes me as very optimistic to distinguish four (at least) clear categories, but you have to start somewhere.

Maybe bodily movements are not actions, but only part of an agent's action of moving [Wilson/Schpall]
|
|
Full Idea:
Some say that the movement's of agent's body are never actions. It is only the agent's direct moving of, say, his leg that constitutes a physical action; the leg movement is merely caused by and/or incorporated as part of the act of moving.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 1.2)
|
|
A reaction:
[they cite Jennifer Hornsby 1980] It seems normal to deny a twitch the accolade of an 'action', so I suppose that is right. Does the continual movement of my tongue count as action? Only if I bring it under control? Does it matter? Only in forensics.

Is the action the arm movement, the whole causal process, or just the trying to do it? [Wilson/Schpall]
|
|
Full Idea:
Some philosophers have favored the overt arm movement the agent performs, some favor the extended causal process he initiates, and some prefer the relevant event of trying that precedes and 'generates' the rest.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 1.2)
|
|
A reaction:
[Davidson argues for the second, Hornsby for the third] There seems no way to settle this, and a compromise looks best. Mere movement won't do, and mere trying won't do, and whole processes get out of control.

To be intentional, an action must succeed in the manner in which it was planned [Wilson/Schpall]
|
|
Full Idea:
If someone fires a bullet to kill someone, misses, and dislodges hornets that sting him to death, this implies that an intentional action must include succeeding in a manner according to the original plan.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 2)
|
|
A reaction:
[their example, compressed] This resembles Gettier's problem cases for knowledge. If the shooter deliberately and maliciously brought down the hornet's nest, that would be intentional murder. Sounds right.

If someone believes they can control the lottery, and then wins, the relevant skill is missing [Wilson/Schpall]
|
|
Full Idea:
If someone enters the lottery with the bizarre belief that they can control who wins, and then wins it, that suggest that intentional actions must not depend on sheer luck, but needs competent exercise of the relevant skill.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 2)
|
|
A reaction:
A nice companion to Idea 20022, which show that a mere intention is not sufficient to motivate and explain an action.
|

|
We might intend two ways to acting, knowing only one of them can succeed [Wilson/Schpall]
|
|
Full Idea:
If an agent tries to do something by two different means, only one of which can succeed, then the behaviour is rational, even though one of them is an attempt to do an action which cannot succeed.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 2)
|
|
A reaction:
[a concise account of a laborious account of an example from Bratman 1984, 1987] Bratman uses this to challenge the 'Simple View', that intention leads straightforwardly to action.
|
|
20031
|
On one model, an intention is belief-desire states, and intentional actions relate to beliefs and desires [Wilson/Schpall]
|
|
Full Idea:
On the simple desire-belief model, an intention is a combination of desire-belief states, and an action is intentional in virtue of standing in the appropriate relation to these simpler terms.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 4)
|
|
A reaction:
This is the traditional view found in Hume, and is probably endemic to folk psychology. They cite Bratman 1987 as the main opponent of the view.

Groups may act for reasons held by none of the members, so maybe groups are agents [Wilson/Schpall]
|
|
Full Idea:
Rational group action may involve a 'collectivising of reasons', with participants acting in ways that are not rationally recommended from the individual viewpoint. This suggests that groups can be rational, intentional agents.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 2)
|
|
A reaction:
[Pettit 2003] is the source for this. Gilbert says individuals can have joint commitment; Pettit says the group can be an independent agent. The matter of shared intentions is interesting, but there is no need for the ontology to go berserk.
|
|
20027
|
If there are shared obligations and intentions, we may need a primitive notion of 'joint commitment' [Wilson/Schpall]
|
|
Full Idea:
An account of mutual obligation to do something may require that we give up reductive individualist accounts of shared activity and posit a primitive notion of 'joint commitment'.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 2)
|
|
A reaction:
[attributed to Margaret Gilbert 2000] If 'we' are trying to do something, that seems to give an externalist picture of intentions, rather like all the other externalisms floating around these days. I don't buy any of it, me.

Strong Cognitivism implies a mode of 'practical' knowledge, not based on observation [Wilson/Schpall]
|
|
Full Idea:
Strong Cognitivists say intentions/beliefs are not based on observation or evidence, and are causally reliable in leading to appropriate actions, so this is a mode of 'practical' knowledge that has not been derived from observation.
|
|
From:
Wilson,G/Schpall,S (Action [2012], 1.1)
|
|
A reaction:
[compressed - Stanford unnecessarily verbose!] I see no mention in this discussion of 'hoping' that your action will turn out OK. We are usually right to hope, but it would be foolish to say that when we reach for the salt we know we won't knock it over.
