| 11211 | If a sound conclusion comes from two errors that cancel out, the path of the argument must matter [Rumfitt] |
| Full Idea: If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], II) | |
| A reaction: The drift of this is that our view of logic should be a little closer to the reasoning of ordinary language, and we should rely a little less on purely formal accounts. |
| 11210 | Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt] |
| Full Idea: If 'and' and 'but' really are alike in sense, in what might that likeness consist? Some philosophers of classical logic will reply that they share a sense by virtue of sharing a truth table. | |
| From: Ian Rumfitt ("Yes" and "No" [2000]) | |
| A reaction: This is the standard view which Rumfitt sets out to challenge. |
| 11212 | The sense of a connective comes from primitively obvious rules of inference [Rumfitt] |
| Full Idea: A connective will possess the sense that it has by virtue of its competent users' finding certain rules of inference involving it to be primitively obvious. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], III) | |
| A reaction: Rumfitt cites Peacocke as endorsing this view, which characterises the logical connectives by their rules of usage rather than by their pure semantic value. |
| 22062 | Mental presentation are not empirical, but concern the strivings of the self [Fichte] |
| Full Idea: The intelligence has as the object of its presentation not an empirical perception, but rather only the necessary striving of the self. | |
| From: Johann Fichte (Review of 'Aenesidemus' [1792], Wks I:22), quoted by Ludwig Siep - Fichte p.62 | |
| A reaction: The embodiment of Fichte's idealism. The 'striving' is the spontaneous application of concepts described the Kant. Kant looks outwards, but Fichte sees only the striving. |
| 22015 | The thing-in-itself is an empty dream [Fichte, by Pinkard] |
| Full Idea: Fichte said that the thing-in-itself (which both Reinhold and Schulze accepted) is only "a piece of whimsy, a pipe-dream, a non-thought". | |
| From: report of Johann Fichte (Review of 'Aenesidemus' [1792]) by Terry Pinkard - German Philosophy 1760-1860 05 | |
| A reaction: This seems to be a key moment in German philosophy, and the first step towards the idealist interpretation of Kant. |
| 11214 | We learn 'not' along with affirmation, by learning to either affirm or deny a sentence [Rumfitt] |
| Full Idea: The standard view is that affirming not-A is more complex than affirming the atomic sentence A itself, with the latter determining its sense. But we could learn 'not' directly, by learning at once how to either affirm A or reject A. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], IV) | |
| A reaction: [compressed] This seems fairly anti-Fregean in spirit, because it looks at the psychology of how we learn 'not' as a way of clarifying what we mean by it, rather than just looking at its logical behaviour (and thus giving it a secondary role). |
| 22818 | Liberals are not too individualistic, because people recognise and value social relations [Kymlicka] |
| Full Idea: It is alleged that liberals fail to recognise that people are naturally social or communal. …But liberals believe that people form and join social relations in which they come to understand and pursue the good. | |
| From: Will Kymlicka (Liberal Individualism and Liberal Neutrality [1989], Conc) | |
| A reaction: This is particulary aimed at communitarians, who see liberalism as based on a distorted concept of people as isolated beings. Personally I am beginning to shift my views from Aristotelian communitarianism to modern liberalism, so I like this idea. |
