A true proposition seems true of one fact, but a false proposition seems true of nothing at all. [Ryle]
|
|
Full Idea:
Whereas there might be just one fact that a true proposition was like, we would have to say that a false proposition was unlike any fact. We could not speak of the fact that it was false of, so we could not speak of its being false of anything at all.

From:
Gilbert Ryle (Are there propositions? [1930], 'Objections')
|
|
A reaction:
Ryle brings out very nicely the point Russell emphasised so much, that the most illuminating studies in philosophy are of how falsehood works, rather than of how truths work. If I say 'the Queen is really a man' it is obvious what that is false of.

Logic studies consequence, compatibility, contradiction, corroboration, necessitation, grounding.... [Ryle]
|
|
Full Idea:
Logic studies the way in which one thing follows from another, in which one thing is compatible with another, contradicts, corroborates or necessitates another, is a special case of another or the nerve of another. And so on.
|
|
From:
Gilbert Ryle (Are there propositions? [1930], IV)
|
|
A reaction:
I presume that 'and so on' would include how one thing proves another. This is quite a nice list, which makes me think a little more widely about the nature of logic (rather than just about inference). Incompatibility isn't a process.

Representation assumes you know the ideas, and the reality, and the relation between the two [Ryle]
|
|
Full Idea:
The theory of Representative Ideas begs the whole question, by assuming a) that we can know these 'Ideas', b) that we can know the realities they represent, and c) we can know a particular 'idea' to be representative of a particular reality.
|
|
From:
Gilbert Ryle (Are there propositions? [1930], 'Objections')
|
|
A reaction:
Personally I regard the ideas as immediate (rather than acquired by some knowledge process), and I am dimly hoping that they represent reality (or I'm in deep trouble), and I am struggling to piece together the reality they represent. I'm happy with that.

Several people can believe one thing, or make the same mistake, or share one delusion [Ryle]
|
|
Full Idea:
We ordinarily find no difficulty in saying of a given thing that several people believe it and so, if they think it false, 'make the same mistake' or 'labour under the same delusion'.
|
|
From:
Gilbert Ryle (Are there propositions? [1930], IV)
|
|
A reaction:
Ryle is playing devil's advocate, but this (like 13980) strikes me as quite good support for propositions. I suppose you can describe these phenomena as assent to sentences, but they might be very different sentences to express the same delusion.
|

|
There are no propositions; they are just sentences, used for thinking, which link to facts in a certain way [Ryle]
|
|
Full Idea:
There are no substantial propositions...There is just a relation between grammatical structure and the logical structure of facts. 'Proposition' denotes the same as 'sentence' or 'statement'. A proposition is not what I think, but what I think or talk in.
|
|
From:
Gilbert Ryle (Are there propositions? [1930], 'Conclusions')
|
|
A reaction:
The conclusion of Ryle's discussion, but I found his support for propositions much more convincing than his critique of them, or his attempt at an alternative linguistic account. He never mentioned animals, so he self-evidently hasn't grasped the problem.

|
If we accept true propositions, it is hard to reject false ones, and even nonsensical ones [Ryle]
|
|
Full Idea:
All the arguments for the subsistence of true propositions seem to hold good for the subsistence of false ones. We might even have to find room for absurd or nonsensical ones like 'some round squares are not red-headed'.
|
|
From:
Gilbert Ryle (Are there propositions? [1930], 'Objections')
|
|
A reaction:
A particularly nice example of a Category Mistake from the man who made them famous. Why can't we just make belief a proposition attitude, so I equally believe 'sea is blue', 'grass is pink' and 'trees are bifocal', but the status of my belief varies?

Saying the good is useful or choiceworth or happiness-creating is not the good, but a feature of it [Sext.Empiricus]
|
|
Full Idea:
Asserting that the good is 'the useful', or 'what is choiceworthy for its own sake', or 'that which contributes to happiness', does not teach us what good is but states its accidental property.
|
|
From:
Sextus Empiricus (Against the Ethicists (one book) [c.180], II.35)
|
|
A reaction:
This seems to be a pretty accurate statement of Moore's famous Open Question argument. I read it in an Aristotelian way - that that quest is always for the essential nature of the thing itself, not for its role or function or use.

Like a warming fire, what is good by nature should be good for everyone [Sext.Empiricus]
|
|
Full Idea:
Just as fire which is warmth-giving by nature warms all men, and does not chill some of them, so what is good by nature ought to be good for all, and not good for some but not good for others.
|
|
From:
Sextus Empiricus (Against the Ethicists (one book) [c.180], II.69)
|
|
A reaction:
This is going to confine the naturally good to the basics of life, which we all share. Is a love of chess a natural good? It seems to capture an aspect of human nature, without appealing to everyone. Sextus says nothing is good for everyone.

If a desire is itself desirable, then we shouldn't desire it, as achieving it destroys it [Sext.Empiricus]
|
|
Full Idea:
If the desire for wealth or health is desirable, we ought not to purse wealth or health, lest by acquiring them we cease to desire them any longer.
|
|
From:
Sextus Empiricus (Against the Ethicists (one book) [c.180], II.81)
|
|
A reaction:
He is investigating whether desires can be desirable, and if so which ones. Roots of this are in Plato's 'Gorgias' on drinking water. Similar to 'if compassion is the highest good then we need lots of suffering'. Desire must be a means, not an end.
