8 ideas
| 7401 | Heat and colour don't exist, so cannot mislead about the external world [Galileo, by Tuck] |
| Full Idea: Galileo argued that there is no such thing as heat (and hence also as colour) in the external world, so there is no reason to conclude from colour-blindness that we cannot know the truth about the world. | |
| From: report of Galileo Galilei (Il Saggiatore ('The Assayer') [1623]) by Richard Tuck - Hobbes Ch.1 | |
| A reaction: This key idea, taken up by Gassendi, Descartes and Locke, seems to me to be one of the most important (and, in retrospect, rather obvious) facts ever worked out by the human mind. Why does anyone still doubt it? |
| 5454 | Tastes, odours and colours only reside in consciousness, and would disappear with creatures [Galileo] |
| Full Idea: I think tastes, odours, colours, and so on are mere names as far as the objects are concerned, and only reside in consciousness. Hence if the living creature were removed, all these qualities would be wiped away and annihilated. | |
| From: Galileo Galilei (Il Saggiatore ('The Assayer') [1623]), quoted by Brian Ellis - The Philosophy of Nature: new essentialism Ch.3 | |
| A reaction: A nice bold assertion of the primary/secondary distinction from the first great scientist. I agree, and to disagree (and hence side with Berkeley and Hume) is to head for metaphsical and epistemological confusion. |
| 16560 | Galileo introduced geometrico-mechanical explanation, based on Archimedes [Galileo, by Machamer/Darden/Craver] |
| Full Idea: The modern idea of explaining with mechanisms became current in the 17th century when Galileo articulated a geometrico-mechanical form of explanation based on Archimedes' simple machines. This became the 'mechanical philosophy'. | |
| From: report of Galileo Galilei (Il Saggiatore ('The Assayer') [1623]) by Machamer,P/Darden,L/Craver,C - Thinking About Mechanisms 5.2 | |
| A reaction: So is Archimedes the source? I would say that mechanical explanation is just commonsense, and is predominant in all human thinking, even in tiny infants. |
| 12167 | Reference without predication is the characteristic of expression [Scruton] |
| Full Idea: Characteristic of expression is the presence of 'reference' without predication. | |
| From: Roger Scruton (Representation in Music [1976], p.71) | |
| A reaction: This echoes (in linguistic terms) Kant's thought that art is 'purposive without purpose'. The remark is comfortable in an essay on music, but it gets more tricky when the topic is literature, or even representational painting. |
| 12166 | If music refers to love, it contains no predication, so it is expression, not language [Scruton] |
| Full Idea: If a passage carries a reference to love, we are not told what it says about love. And to speak of language with 'reference' but no predication is simply to misuse the word. We leave the realm of representation and enter that of expression. | |
| From: Roger Scruton (Representation in Music [1976], p.63-4) | |
| A reaction: This is a beautifully simple objection to the idea (associated with Nelson Goodman) that art is a language. Though what an 'expression' of something amounts to I am not quite sure. |
| 12168 | Music is not representational, since thoughts about a subject are never essential to it [Scruton] |
| Full Idea: Music is not representational, since thoughts about a subject are never essential to the understanding of music. | |
| From: Roger Scruton (Representation in Music [1976], p.74) | |
| A reaction: I would not have thought that many people thought music was representational, but Scruton particularly mentions passages in opera that seem to pick up aspects of the story. Do even bell sounds not represent bells? |
| 6017 | Nomos is king [Pindar] |
| Full Idea: Nomos is king. | |
| From: Pindar (poems [c.478 BCE], S 169), quoted by Thomas Nagel - The Philosophical Culture | |
| A reaction: This seems to be the earliest recorded shot in the nomos-physis wars (the debate among sophists about moral relativism). It sounds as if it carries the full relativist burden - that all that matters is what has been locally decreed. |
| 3645 | To understand the universe mathematics is essential [Galileo] |
| Full Idea: The great book of the universe cannot be understood unless one can understand the language in which it is written - the language of mathematics. | |
| From: Galileo Galilei (Il Saggiatore ('The Assayer') [1623], VI.232) | |
| A reaction: Nice, though one might say that humans created the language of maths to help them discuss the patterns they perceived in nature. Maybe what is special is order, and all order can be described mathematically. |
