16010 | While faith is a passion (as Kierkegaard says), wisdom is passionless [Wittgenstein] |
Full Idea: Wisdom is passionless. But faith by contrast is what Kierkegaard calls a passion. | |
From: Ludwig Wittgenstein (Culture and Value [1945], 53e) | |
A reaction: [Idea from SY] Personally I don't agree that wisdom is passionless. At the very least, Aristotle allows the wise person to be appropriately angry. [PG] |
4037 | Ockham's Razor is the principle that we need reasons to believe in entities [Mellor/Oliver] |
Full Idea: Ockham's Razor is the principle that we need reasons to believe in entities. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §9) | |
A reaction: This presumably follows from an assumption that all beliefs need reasons, but is that the case? The Principle of Sufficient Reason precedes Ockham's Razor. |
17743 | De Morgan introduced a 'universe of discourse', to replace Boole's universe of 'all things' [De Morgan, by Walicki] |
Full Idea: In 1846 De Morgan introduced the enormously influential notion of a possibly arbitrary and stipulated 'universe of discourse'. It replaced Boole's original - and metaphysically a bit suspect - universe of 'all things'. | |
From: report of Augustus De Morgan (works [1846]) by Michal Walicki - Introduction to Mathematical Logic History D.1.1 | |
A reaction: This not only brings formal logic under control, but also reflects normal talk, because there is always an explicit or implicit domain of discourse when we talk. Of virtually any conversation, you can say what it is 'about'. |
4027 | Properties are respects in which particular objects may be alike or differ [Mellor/Oliver] |
Full Idea: Properties are respects in which particular objects may be alike or differ. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §1) | |
A reaction: Note that this definition does not mention a causal role for properties. |
4029 | Nominalists ask why we should postulate properties at all [Mellor/Oliver] |
Full Idea: Nominalists ask why we should postulate properties at all. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §3) | |
A reaction: Objects might be grasped without language, but events cannot be understood, and explanations of events seem inconceivable without properties (implying that they are essentially causal). |
4039 | Abstractions lack causes, effects and spatio-temporal locations [Mellor/Oliver] |
Full Idea: Abstract entities (such as sets) are usually understood as lacking causes, effects, and spatio-temporal location. | |
From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §10) | |
A reaction: This seems to beg some questions. Has the ideal of 'honour' never caused anything? Young men dream of pure velocity. |
