| 10580 | Mathematics is both necessary and a priori because it really consists of logical truths [Yablo] |
| Full Idea: Mathematics seems necessary because the real contents of mathematical statements are logical truths, which are necessary, and it seems a priori because logical truths really are a priori. | |
| From: Stephen Yablo (Abstract Objects: a Case Study [2002], 10) | |
| A reaction: Yablo says his logicism has a Kantian strain, because numbers and sets 'inscribed on our spectacles', but he takes a different view (in the present Idea) from Kant about where the necessity resides. Personally I am tempted by an a posteriori necessity. |
| 10579 | Putting numbers in quantifiable position (rather than many quantifiers) makes expression easier [Yablo] |
| Full Idea: Saying 'the number of Fs is 5', instead of using five quantifiers, puts the numeral in quantifiable position, which brings expressive advantages. 'There are more sheep in the field than cows' is an infinite disjunction, expressible in finite compass. | |
| From: Stephen Yablo (Abstract Objects: a Case Study [2002], 08) | |
| A reaction: See Hofweber with similar thoughts. This idea I take to be a key one in explaining many metaphysical confusions. The human mind just has a strong tendency to objectify properties, relations, qualities, categories etc. - for expression and for reasoning. |
| 10577 | Concrete objects have few essential properties, but properties of abstractions are mostly essential [Yablo] |
| Full Idea: Objects like me have a few essential properties, and numerous accidental ones. Abstract objects are a different story. The intrinsic properties of the empty set are mostly essential. The relations of numbers are also mostly essential. | |
| From: Stephen Yablo (Abstract Objects: a Case Study [2002], 01) |
| 10578 | We are thought to know concreta a posteriori, and many abstracta a priori [Yablo] |
| Full Idea: Our knowledge of concreta is a posteriori, but our knowledge of numbers, at least, has often been considered a priori. | |
| From: Stephen Yablo (Abstract Objects: a Case Study [2002], 02) |
| 13120 | Chisholm divides things into contingent and necessary, and then individuals, states and non-states [Chisholm, by Westerhoff] |
| Full Idea: Chisholm's Ontological Categories: ENTIA - {Contingent - [Individual - (Boundaries)(Substances)] [States - (Events)]} {Necessary - [States] [Non-States - (Attributes)(Substance)]} | |
| From: report of Roderick Chisholm (A Realistic Theory of Categories [1996], p.3) by Jan Westerhoff - Ontological Categories §01 | |
| A reaction: [I am attempting a textual representation of a tree diagram! The bracket-styles indicate the levels.] |
| 24016 | Consciousness always transcends itself [Sartre] |
| Full Idea: It is of the essence of consciousness to transcend itself | |
| From: Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939], §III) | |
| A reaction: As usual, I am a bit baffled by these sorts of pronouncement. Sounds like an oxymoron to me. Maybe it is a development of Schopenhauer's thought. |
| 24013 | An emotion and its object form a unity, so emotion is a mode of apprehension [Sartre] |
| Full Idea: Emotion returns to its object every moment, and feeds upon it. …The emotional subject and the object of the emotion are united in an indissoluble synthesis. Emotion is a specific manner of apprehending the world. …[39] It is a transformation of the world. | |
| From: Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939], §III) | |
| A reaction: The last sentence is the essence (or existence?) of Sartre's core theory of the emotions. They are, it seems, a mode of perception, like a colour filter added to a camera. I don't think I agree. I see them as a response to perceptions, not part of them. |
| 24017 | Emotion is one of our modes of understanding our Being-in-the-World [Sartre] |
| Full Idea: Emotion is not an accident, it is a mode of our conscious existence, one of the ways in which consciousness understands (in Heidegger's sense of verstehen) its Being-in-the-World. …It has a meaning. | |
| From: Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939], §III) | |
| A reaction: Calling emotions a 'mode' suggests that this way of understanding is intermittent, which seems wrong. Even performing arithmetical calculations is coloured by emotions, so they go deeper than a 'mode'. |
| 24014 | Emotions are a sort of bodily incantation which brings a magic to the world [Sartre] |
| Full Idea: Joy is the magical behaviour which tries, by incantation, to realise the possession of the desired object as an instantaneous totality. [47] Emotions are all reducible to the constitution of a magic world by using our bodies as instruments of incantation. | |
| From: Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939], §III) | |
| A reaction: I can't pretend to understand this, but I am reminded of the fact that the so-called primary qualities of perception are innately boring, and it is only the secondary qualities (like colour and smell) which make the world interesting. |
| 24015 | Emotions makes us believe in and live in a new world [Sartre] |
| Full Idea: Emotion is a phenomenon of belief. Consciousness does not limit itself to the projection of affective meanings upon the world around it; it lives the new world it has thereby constituted. | |
| From: Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939], §III) | |
| A reaction: There seems to be an implied anti-realism in this, since the emotions prevent us from relating more objectively to the world. The 'magic' seems to be compulsory. |
| 20491 | States have a monopoly of legitimate violence [Sartre, by Wolff,J] |
| Full Idea: Max Weber observed that states possess a monopoly of legitimate violence. | |
| From: report of Jean-Paul Sartre (Sketch for a Theory of the Emotions [1939]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 2 'State' | |
| A reaction: This sounds rather hair-raising, and often is, but it sounds quite good if we describe it as a denial of legitimate violence to individual citizens. Hobbes would like it, since individual violence breaches some sort of natural contract. Guns in USA. |
