13 ideas
1813 | All reasoning endlessly leads to further reasoning (Mode 12) [Agrippa, by Diog. Laertius] |
Full Idea: Twelfth mode: all reasoning leads on to further reasoning, and this process goes on forever. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1815 | Reasoning needs arbitrary faith in preliminary hypotheses (Mode 14) [Agrippa, by Diog. Laertius] |
Full Idea: Fourteenth mode: reasoning requires arbitrary faith in preliminary hypotheses. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1812 | All discussion is full of uncertainty and contradiction (Mode 11) [Agrippa, by Diog. Laertius] |
Full Idea: Eleventh mode: all topics of discussion are full of uncertainty and contradiction. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
1811 | Proofs often presuppose the thing to be proved (Mode 15) [Agrippa, by Diog. Laertius] |
Full Idea: Fifteenth mode: proofs often presuppose the thing to be proved. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
8850 | Agrippa's Trilemma: justification is infinite, or ends arbitrarily, or is circular [Agrippa, by Williams,M] |
Full Idea: Agrippa's Trilemma offers three possible outcomes for a regress of justification: the chain goes on for ever (infinite); or the chain stops at an unjustified proposition (arbitrary); or the chain eventually includes the original proposition (circular). | |
From: report of Agrippa (fragments/reports [c.60], §2) by Michael Williams - Without Immediate Justification §2 | |
A reaction: This summarises Ideas 1911, 1913 and 1914. Agrippa's Trilemma is now a standard starting point for modern discussions of foundations. Personally I reject 2, and am torn between 1 (+ social consensus) and 3 (with a benign, coherent circle). |
1814 | Everything is perceived in relation to another thing (Mode 13) [Agrippa, by Diog. Laertius] |
Full Idea: Thirteenth mode: everything is always perceived in relation to something else. | |
From: report of Agrippa (fragments/reports [c.60]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.10 |
22808 | Liberalism is minimal government, or individual rights, or equality [Avineri/De-Shalit] |
Full Idea: Liberalism has been defended as a theory of minimal government, or as a theory of basic individual rights, or as an egalitarian philosophy. | |
From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
A reaction: Minimal government tends towards anarchist liberalism, but then what grounds the right to be free of government? Presumably any sensible theory of rights has to be egalitarian. What could ground unequal rights? |
22803 | Can individualist theories justify an obligation to fight in a war? [Avineri/De-Shalit] |
Full Idea: How can an individualist theory justify an obligation to fight for the state in the case of war? | |
From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §4) | |
A reaction: The most dramatic example of obliging citizens to contribute to the state, the notable other case being taxes. Some imagined ancient 'social contract' doesn't seem sufficient for later generations. Does being naturally sociable create such obligations? |
22804 | Autonomy is better achieved within a community [Avineri/De-Shalit] |
Full Idea: Communitarians often argue that personal autonomy is better achieved within the community. | |
From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §4) | |
A reaction: Hegel is the source of this view. The simplest version of the point is that autonomy can only be asserted if a person has rights, which can be asserted and defended, and only a society can provide that. That is plausible. |
22806 | Communitarians avoid oppression for the common good, by means of small mediating communities [Avineri/De-Shalit] |
Full Idea: Because of the mediating structures of small communities, communitarians are less fearful [than liberals] of the emergence of an oppressive government as a result of the politics of the common good. | |
From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
A reaction: A politics of the common good has an obvious implicit conservatism because the central consensus is always likely to disapprove of errant individuals, of all sorts. Only individual rights can block an oppressive government. |
22807 | If our values are given to us by society then we have no grounds to criticise them [Avineri/De-Shalit] |
Full Idea: If communitarians are right that we are not free to choose, but rather that our values are determined by our community, the individualists say, then there is no reason to criticise the values of one's society. | |
From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
A reaction: This is an obvious challenge, but if one's concept of community is a forum for free debate then it can be overcome. There is no avoiding the fact, though, that a good community always needs a high degree of consensus. |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
