1403 | A rational donkey would starve to death between two totally identical piles of hay [Buridan, by PG] |
Full Idea: A rational donkey faced with two totally identical piles of hay would be unable to decide which one to eat first, and would therefore starve to death | |
From: report of Jean Buridan (talk [1338]) by PG - Db (ideas) | |
A reaction: also De Caelo 295b32 (Idea 19740). |
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. |
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. |
23169 | Democratic institutions become impossible in a fanatical democracy [Russell] |
Full Idea: Even democracy, when it becomes fanatical, as it did …in the French Revolution, ceases to be Liberal. Indeed, a fanatical belief in democracy makes democratic institutions impossible. | |
From: Bertrand Russell (Philosophy and Politics [1950], p.26) | |
A reaction: Presumably this is because the supposed 'will of the people' is continually placed in opposition to the institutions. For example, there is a problem if a referendum is held, which produces a result in conflict with the institutions. |
23170 | Liberal opinions are tentative rather than dogmatic, and are always responsive to new evidence [Russell] |
Full Idea: The essence of the Liberal outlook lies ...in how opinions are held: instead of being held dogmatically, they are held tentatively (as they are in science), and with a consciousness that new evidence may at any moment lead to their abandonment. | |
From: Bertrand Russell (Philosophy and Politics [1950], p.26) | |
A reaction: A nice assessment. Russell shows himself finally to be a Liberal. This flexible approach to opinions is what infuriates dogmatists from both the left and the right. It might be said that the basic evidence rarely changes. |
23172 | Empiricist Liberalism is the only view for someone who favours scientific evidence and happiness [Russell] |
Full Idea: Empiricist Liberalism (not incompatible with democratic socialism) is, as in Locke's time, the only philosophy that can be adopted by a man who demands some scientific evidence for beliefs, and also desires human happiness more than some party or creed. | |
From: Bertrand Russell (Philosophy and Politics [1950], p.31) | |
A reaction: I like this way of presenting liberalism. In the modern world we are sunk if we don't pay attention to experts, so we all need a critical understanding of what counts as good evidence. Tricky in a world of lying media. |
23171 | Empiricism is ethically superior, because dogmatism favours persecution and hatred [Russell] |
Full Idea: Empiricism is to be commended not only on the grounds of its greater truth, but also on ethical grounds. Dogma demands authority rather than intelligent thought; it requires persecution of heretics and unbelievers, and favours systematic hatred. | |
From: Bertrand Russell (Philosophy and Politics [1950], p.31) | |
A reaction: He links empiricism with the liberal outlook. At its best, the respect by empiricists for evidence is a sort of humility. |
