| 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. |
| 3745 | Must sentences make statements to qualify for truth? [O'Connor] |
| Full Idea: Maybe a sentence is not a candidate for truth until it is used to make a statement. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3742 | Beliefs must match facts, but also words must match beliefs [O'Connor] |
| Full Idea: Our beliefs must claim a correspondence with facts, and then the verbal expression of the belief must correspond to the belief itself. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.4) |
| 3744 | The semantic theory requires sentences as truth-bearers, not propositions [O'Connor] |
| Full Idea: The Semantic Theory of truth requires that sentences are truth-bearers (rather than statements, or propositions). | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3749 | What does 'true in English' mean? [O'Connor] |
| Full Idea: We do not seem to have any use in ordinary discourse for phrases like 'true in English', 'false in German'. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], II.1) |
| 3746 | Logic seems to work for unasserted sentences [O'Connor] |
| Full Idea: If sentences can have truth-values only when they occur as asserted, it would be impossible to have a truth-functional basis to logic. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.6) |
| 3747 | Events are fast changes which are of interest to us [O'Connor] |
| Full Idea: The standard cases of events are physical changes which happen sufficiently fast to be observed as changes, and which are of sufficient interest to us to be noticed or commented on. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.7) |
| 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). |
| 3743 | We can't contemplate our beliefs until we have expressed them [O'Connor] |
| Full Idea: It is only when beliefs are given some symbolic expression that they acquire the precision and stability that enables us to entertain them. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.5) |
| 3748 | Without language our beliefs are particular and present [O'Connor] |
| Full Idea: Without language we would be restricted to particular beliefs about the here and now. | |
| From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.8) |
| 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. |
| 19216 | Propositions (such as 'that dog is barking') only exist if their items exist [Williamson] |
| Full Idea: A proposition about an item exists only if that item exists... how could something be the proposition that that dog is barking in circumstances in which that dog does not exist? | |
| From: Timothy Williamson (Necessary Existents [2002], p.240), quoted by Trenton Merricks - Propositions | |
| A reaction: This is a view of propositions I can't make sense of. If I'm under an illusion that there is a dog barking nearby, when there isn't one, can I not say 'that dog is barking'? If I haven't expressed a proposition, what have I done? |
