14767 | The demonstrations of the metaphysicians are all moonshine [Peirce] |
Full Idea: The demonstrations of the metaphysicians are all moonshine. | |
From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
14764 | I am saturated with the spirit of physical science [Peirce] |
Full Idea: I am saturated, through and through, with the spirit of the physical sciences. | |
From: Charles Sanders Peirce (Concerning the Author [1897], p.1) |
21597 | Logical connectives have the highest precision, yet are infected by the vagueness of true and false [Russell, by Williamson] |
Full Idea: Russell says the best chance of avoiding vagueness are the logical connectives. ...But the vagueness of 'true' and 'false' infects the logical connectives too. All words are vague. Russell concludes that all language is vague. | |
From: report of Bertrand Russell (Vagueness [1923]) by Timothy Williamson - Vagueness 2.4 | |
A reaction: This relies on the logical connectives being defined semantically, in terms of T and F, but that is standard. Presumably the formal uninterpreted syntax is not vague. |
9051 | Since natural language is not precise it cannot be in the province of logic [Russell, by Keefe/Smith] |
Full Idea: Russell takes it that logic assumes precision, and since natural language is not precise it cannot be in the province of logic at all. | |
From: report of Bertrand Russell (Vagueness [1923]) by R Keefe / P Smith - Intro: Theories of Vagueness §1 | |
A reaction: I find this view congenial. It seems to me that the necessary prelude to logic is to do everything you can to eliminate ambiguity and vagueness from the sentences at issue. We want the proposition, or logical form. If there isn't one, forget it? |
9054 | Vagueness is only a characteristic of representations, such as language [Russell] |
Full Idea: Vagueness and precision alike are characteristics which can only belong to a representation, of which language is an example. | |
From: Bertrand Russell (Vagueness [1923], p.62) | |
A reaction: Russell was the first to tackle the question of vagueness, and he may have got it right. If we are unable to decide which set an object belongs in (red or orange) that is a problem for our conceptual/linguistic scheme. The object still has a colour! |
14768 | Infallibility in science is just a joke [Peirce] |
Full Idea: Infallibility in scientific matters seems to me irresistibly comical. | |
From: Charles Sanders Peirce (Concerning the Author [1897], p.3) |
14765 | Association of ideas is the best philosophical idea of the prescientific age [Peirce] |
Full Idea: The doctrine of the association of ideas is, to my thinking, the finest piece of philosophical work of the prescientific ages. | |
From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
14766 | Duns Scotus offers perhaps the best logic and metaphysics for modern physical science [Peirce] |
Full Idea: The works of Duns Scotus have strongly influenced me. …His logic and metaphysics, torn away from its medievalism, …will go far toward supplying the philosophy which is best to harmonize with physical science. | |
From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
5994 | Is the cosmos open or closed, mechanical or teleological, alive or inanimate, and created or eternal? [Robinson,TM, by PG] |
Full Idea: The four major disputes in classical cosmology were whether the cosmos is 'open' or 'closed', whether it is explained mechanistically or teleologically, whether it is alive or mere matter, and whether or not it has a beginning. | |
From: report of T.M. Robinson (Classical Cosmology (frags) [1997]) by PG - Db (ideas) | |
A reaction: A nice summary. The standard modern view is closed, mechanistic, inanimate and non-eternal. But philosophers can ask deeper questions than physicists, and I say we are entitled to speculate when the evidence runs out. |
