9. Objects / D. Essence of Objects / 3. Individual Essences
Scientific essentialism doesn't really need Kripkean individual essences [Ellis]
     Full Idea: My current view is that individual essences (about which Kripke's essentialism has a lot to say) do not matter much from the point of view of a scientific essentialist.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: [Kripke parenthesis on p.54] Presumably this is because science is only committed to dealing in generalities, and so natural kinds are needed for such things. I'm inclined to regard individual essences as prior in the pure ontology of the thing.
9. Objects / D. Essence of Objects / 4. Essence as Definition
Objects have an essential constitution, producing its qualities, which we are too ignorant to define [Reid]
     Full Idea: Individuals and objects have a real essence, or constitution of nature, from which all their qualities flow: but this essence our faculties do not comprehend. They are therefore incapable of definition.
     From: Thomas Reid (Essays on Intellectual Powers 4: Conception [1785], 1)
     A reaction: Aha - he's one of us! I prefer the phrase 'essential nature' of an object, which is understood, I think, by everyone. I especially like the last bit, directed at those who mistakenly think that Aristotle identified the essence with the definition.
Fregean meanings are analogous to conceptual essence, defining a kind [Almog]
     Full Idea: Ever since Frege, semantic definitionalists have posited a meaning ('sinn') for a name; the meaning/sinn is their semantic analog to the conceptual essence, as ontologically defining of the kind.
     From: Joseph Almog (Nature Without Essence [2010], 07)
Essential definition aims at existence conditions and structural truths [Almog]
     Full Idea: The essentialist encapsulating formula is meant to be existence-exhaustive (an attribute the satisfaction of which is logically necessary and sufficient to be the thing) and truth-exhaustive (promising all the structural truths).
     From: Joseph Almog (Nature Without Essence [2010], 01)
     A reaction: [compressed] If he thinks essentialism means that one short phrase can achieve all this, then it is not surprising that Almog renounces his former essentialism in this essay. He may, however, have misunderstood. He should reread Aristotle.
Surface accounts aren't exhaustive as they always allow unintended twin cases [Almog]
     Full Idea: A surface-functional characterisation is not exhaustive. It allows unintended twins, alien intruders with different structures - water lookalikes that are not H2O and lookalike infinite structures that are not the natural numbers.
     From: Joseph Almog (Nature Without Essence [2010], 03)
     A reaction: He rests this on the claim in mathematical logic that fully expressive systems are always non-categorical (having unintended twins). Set theory is not fully categorical, but Peano Arithmetic is. Almog's main anti-essentialist argument.
Definitionalists rely on snapshot-concepts, instead of on the real processes [Almog]
     Full Idea: The definitionalist errs by abstracting away from differences cosmic processes, freezing real, dynamic processes in snapshot-concepts.
     From: Joseph Almog (Nature Without Essence [2010], 08)
     A reaction: You could hardly do science at all if you didn't 'abstract away from the differences in cosmic processes'. We can't write about sea-waves, because they all differ slightly? 'Electron' is a snapshot concept.
9. Objects / D. Essence of Objects / 10. Essence as Species
Alien 'tigers' can't be tigers if they are not related to our tigers [Almog]
     Full Idea: Animals roaming jungles on some planet at the other end of the galaxy with the tiger-look and the tiger genetic make-up but with a disjoint evolutionary history are not the same species as the earthly tigers.
     From: Joseph Almog (Nature Without Essence [2010], 10)
     A reaction: I disagree. If two independent cultures build boats, they are both boats. If we manufacture a tiger which can breed with other tigers, we've made a tiger. His 'tigers' would scream for explanation, precisely because they are tigers. If not, no puzzle.
9. Objects / D. Essence of Objects / 13. Nominal Essence
Kripke and Putnam offer an intermediary between real and nominal essences [Almog]
     Full Idea: Kripke and Putnam offer us enhanced essences, still formulable in one short sentence and locally graspable. They offer between Locke's mind-boggling definitive real essence and his mind-friendly but not definitive nominal essence.
     From: Joseph Almog (Nature Without Essence [2010], 04)
     A reaction: The solution is to add a 'deep structure' which serves both ends.
9. Objects / D. Essence of Objects / 15. Against Essentialism
The old idea that identity depends on essence and behaviour is rejected by the empiricists [Ellis]
     Full Idea: The old Aristotelian idea that the identity of a thing might depend on its essential nature, which would dispose it to behave in certain ways, is firmly rejected by empiricists.
     From: Brian Ellis (Scientific Essentialism [2001], 1.10)
     A reaction: Ellis is accusing empiricists of having a falsely passive concept of objects. This dispute is best captured in the disagreement between Locke and Leibniz on the subject.
Individual essences are just cobbled together classificatory predicates [Almog]
     Full Idea: The key for the essentialist is classificatory predication. It is only a subsequent extension of this prime idea that leads us to cobble together enough such essential predications to make an individuative essential property.
     From: Joseph Almog (Nature Without Essence [2010], 11)
     A reaction: So the essence is just a cross-reference of all the ways we can think of to classify it? I don't think so. Which are the essential classifications?
