Single Idea 5790

[filed under theme 8. Modes of Existence / B. Properties / 3. Types of Properties ]

Full Idea

An emergent property of a system is causally explained by elements of the system, but it is not a property of the elements, and cannot be explained by a summation of their properties. The behaviour of H2O explains liquidity, but molecules aren't liquid.

Gist of Idea

A property is 'emergent' if it is caused by elements of a system, when the elements lack the property

A Reaction

The genie is 'emergent' from the lamp, and so (in Searle's meaning) is the lamp's solidity. I agree that the mind is 'emergent' in Searle's very weak sense, if that only means that one neuron can't be conscious, but lots together can.

Length is a 'determinable' property, and one mile is one its 'determinates' [Armstrong]
The determinates of a determinable must be incompatible with each other [Armstrong]
Properties are 'dispositional', or 'categorical' (the latter as 'block' or 'intrinsic' structures) [Ellis, by PG]
A property is 'emergent' if it is caused by elements of a system, when the elements lack the property [Searle]
Maybe we have abundant properties for semantics, and sparse properties for ontology [Hale/Wright]
We have four options, depending whether particulars and properties are sui generis or constructions [Oliver]
A 'categorial' property is had by virtue of being or having an item from a category [Wedin]
Dispositions and categorical properties are two modes of presentation of the same thing [Mumford]
A property is intrinsic if an object alone in the world can instantiate it [Sider]
Some properties seem to be primitive, but others can be analysed [Merricks]
There might be just one fundamental natural property [Bird]
Being polka-dotted is a 'spatial distribution' property [Cameron]
17th C qualities are either microphysical, or phenomenal, or powers [Pasnau]
A determinate property must be a unique instance of the determinable class [Vetter]
Properties are said to be categorical qualities or non-qualitative dispositions [Ingthorsson]
