13798 | Maybe we should give up the statue [Elder] |
Full Idea: Some contemporary metaphysicians infer that one of the objects must go, namely, the statue. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 7.2) | |
A reaction: [He cites Zimmerman 1995] This looks like a recipe for creating a vast gulf between philosophers and the rest of the population. If it is right, it makes the true ontology completely useless in understanding our daily lives. |
13797 | The loss of an essential property means the end of an existence [Elder] |
Full Idea: The loss of any essential property must amount to the end of an existence. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3) | |
A reaction: This is orthodoxy for essentialists, and I presume that Aristotle would agree, but I have a problem with the essence of a great athlete, who then grows old. Must we say that they lose their identity-as-an-athlete? |
17390 | Natural kinds don't need essentialism to be explanatory [Dupré] |
Full Idea: The importance of natural kinds for explanation does not depend on a doctrine of essences. | |
From: John Dupré (The Disorder of Things [1993], 3) | |
A reaction: He suggest as the alternative that laws do the explaining, employing natural kinds. He allows that individual essences might be explanatory. |
13794 | Essential properties by nature occur in clusters or packages [Elder] |
Full Idea: Essential properties by nature occur in clusters or packages. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 2.2) | |
A reaction: Elder proposes this as his test for the essentialness of a property - his Test of Flanking Uniformities. A nice idea. |
13796 | Essential properties are bound together, and would be lost together [Elder] |
Full Idea: The properties of any essential nature are bound together....[122] so any case in which one of our envisioned familiar objects loses one of its essential properties will be a case in which it loses several. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3) | |
A reaction: This sounds like a fairly good generalisation rather than a necessary truth. Is there a natural selection for properties, so that only the properties which are able to bind to others to form teams are able to survive and flourish? |
17388 | It seems that species lack essential properties, so they can't be natural kinds [Dupré] |
Full Idea: It is widely agreed among biologists that no essential property can be found to demarcate species, so that if an essential property is necessary for a natural kind, species are not natural kinds. | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: This uses 'essential' to mean 'necessary', but I would use 'essential' to mean 'deeply explanatory'. Biological species are, nevertheless, dubious members of an ontological system. Vegetables are the problem. |
17389 | A species might have its essential genetic mechanism replaced by a new one [Dupré] |
Full Idea: Contradicting one of the main points of essentialism, there is no reason in principle why a species should not survive the demise of its current genetic mechanisms (some other species coherence gradually taking over). | |
From: John Dupré (The Disorder of Things [1993], 2) | |
A reaction: I would say that this meant that the species had a new essence, because I don't take what is essential to be the same as what is necessary. The new genetics would replace the old as the basic explanation of the species. |
