10 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. |
| 22265 | I can't defend the view that the majority values of a community are thereby right [Sandel] |
| Full Idea: Insofar as 'communitarian' is another name for majoritarianism, or for the idea that rights should rest on the values that predominate in any given community at any given time, it is not a view I would defend. | |
| From: Michael J. Sandel (The Limits of Communitarianism [1998], 'Where') | |
| A reaction: I should hope not. You could soon end up as a good nazi if you follow that route. Sandel defends a critical view of community values (implying a role for philosophy?). The community good must be continually negotiated. Sounds fine to me. |
| 22268 | If persons define themselves by a group membership, insults to that group are a real harm [Sandel] |
| Full Idea: For persons who understand themselves as defined by the ethnic or religious group to which they belong, an insult to the group can inflict a harm as real and as damaging as some physical harms. | |
| From: Michael J. Sandel (The Limits of Communitarianism [1998], 'Free speech') | |
| A reaction: In Britain many people fully define themselves by their allegiance to a football club. Really! They usually learn to laugh off an insult to their club, but it hurts. Laughing off an insult is an essential modern skill - up to a point. |
| 22267 | In the liberal view an insult to my group doesn't hurt me, since I'm defined by choices not groups [Sandel] |
| Full Idea: By the liberal conception of a person, my dignity could never be damaged by an insult to a group with which I identify, because what matters is not my social role, but my capacity to choose that role. | |
| From: Michael J. Sandel (The Limits of Communitarianism [1998], 'Free speech') | |
| A reaction: If I'm defined by my capacity to choose, and I choose to join some group, why is an insult to that group not an insult to my capacity to choose? How do you insult a liberal? 'I despise your individual freedom!'. |
| 22266 | The case for religious liberty depends on the religion contributing to a morally good life [Sandel] |
| Full Idea: Unless there were reason to believe that religious beliefs and practices contribute to morally admirable ways of life, the case for a right to religious liberty would be weakened. | |
| From: Michael J. Sandel (The Limits of Communitarianism [1998], 'Religious') | |
| A reaction: I think many religious people would deny that their religion is primarily moral. (W.Blake: 'If morality is Christianity, then Socrates was the saviour'). Whose concept of a morally good life is Sandel referring to? |
| 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. |
| 16713 | Philosophers are the forefathers of heretics [Tertullian] |
| Full Idea: Philosophers are the forefathers of heretics. | |
| From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2 |
| 6610 | I believe because it is absurd [Tertullian] |
| Full Idea: I believe because it is absurd ('Credo quia absurdum est'). | |
| From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2 | |
| A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though. |
