There are potential infinities (never running out), but actual infinity is incoherent [Aristotle, by Friend]
|
|
Full Idea:
Aristotle developed his own distinction between potential infinity (never running out) and actual infinity (there being a collection of an actual infinite number of things, such as places, times, objects). He decided that actual infinity was incoherent.

From:
report of Aristotle (works [c.330 BCE]) by Michèle Friend - Introducing the Philosophy of Mathematics 1.3
|
|
A reaction:
Friend argues, plausibly, that this won't do, since potential infinity doesn't make much sense if there is not an actual infinity of things to supply the demand. It seems to just illustrate how boggling and uncongenial infinity was to Aristotle.

Modern accounts of causation involve either processes or counterfactuals [Baron/Miller]
|
|
Full Idea:
The two major contemporary theories of causation are process theories and counterfactual theories. …Process theories treat it as something to be discovered. …Counterfactual theories ignore processes, and treat it in terms of truth and falsity.
|
|
From:
Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.1)
|
|
A reaction:
I take the counterfactual theory to be a specialised branch of the project of analytic metaphysics, which seeks the logical form of causation sentences, using possible worlds semantics. In the real word its processes or nothing.

The main process theory of causation says it is transference of mass, energy, momentum or charge [Baron/Miller]
|
|
Full Idea:
According to contemporary process theories of causation it consists of the transference of a 'mark', which is always some conserved quantity. Candidates (from science) are mass, energy, momentum and electric charge.

|
From:
Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.2.2)
|
|
A reaction:
Given my commitment to physicalism, this is my preferred theory of causation. It began with the suggestion of energy-transfer, but has broadened into the present idea. It is an updated version of the Newton view, as the meeting of objects.

If causes are processes, what is causation by omission? (Distinguish legal from scientific causes?) [Baron/Miller]
|
|
Full Idea:
Process theories of causation face a serious problem, such as killing a plant by failing to water it - a cause by omission. …Defenders of the theory propose two concepts of causation: one for legal and one for scientific contexts.
|
|
From:
Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 6.2.3)
|
|
A reaction:
Not much of a problem, I think. Clearly the scientific concept has priority. The plant died of dehydration, resulting from the consumption and evaporation of the available water. The human causes of that situation are legion.
