3 ideas
| 16051 | Life has a new supervenient relation, which alters its underlying physical events [Morgan,L] |
| Full Idea: When some new kind of relatedness is supervenient (say at the level of life), the way in which the physical events which are involved run their course is different in virtue of its presence. | |
| From: Lloyd Morgan (Emergent Evolution [1923], pp.15-16), quoted by Terence Horgan - From Supervenience to Superdupervenience 1 | |
| A reaction: This is a clear assertion of 'downward causation' at the first introduction of 'supervenience', supporting 'emergentism' about life and mind. That is, the newly-emerged feature has new causal powers that affect the physical system from outside. Wrong! |
| 6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
| Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
| From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
| A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
| 4800 | Natural laws result from eliminative induction, where enumerative induction gives generalisations [Cohen,LJ, by Psillos] |
| Full Idea: Cohen contends that statements that express laws of nature are the products of eliminative induction, where accidentally true generalisations are the products of enumerative induction. | |
| From: report of L. Jonathan Cohen (The Problem of Natural Laws [1980], p.222) by Stathis Psillos - Causation and Explanation §7.1 | |
| A reaction: The idea is that enumerative induction only offers the support of positive instances, where eliminative induction involves attempts to falsify a range of hypotheses. This still bases laws on observed regularities, rather than essences or mechanisms. |
