Essences are used to explain natural kinds, modality, and causal powers [Tahko]
|
|
Full Idea:
Essences are supposed to do a lot of explanatory work: natural kinds can be identified in terms of their essences, metaphysical modality can be reduced to essence, the causal power of objects can be explained with the help of essence.

From:
Tuomas E. Tahko (The Epistemology of Essence (draft) [2013], 1)
|
|
A reaction:
Natural kinds and modality are OK with me, but I'm dubious about the third one. If an essence explains something's causal powers, I have no idea what an essence might be. Essence are largely characterised in terms of causal powers.

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?

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.

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.

If essence is modal and laws are necessary, essentialist knowledge is found by scientists [Tahko]
|
|
Full Idea:
If essence is conceived in terms of modality and the laws of nature are metaphysically necessary, it seems that the laws of nature constitute essentialist knowledge, so the discovery of essences is mostly due to scientists.
|
|
From:
Tuomas E. Tahko (The Epistemology of Essence (draft) [2013], 2.1)
|
|
A reaction:
This seems muddled to me. The idea that the laws themselves are essences is way off target. No one thinks all knowledge of necessities is essentialist. Mumford, for example, doesn't even believe in laws.
