9. Objects / E. Objects over Time / 10. Beginning of an Object
Generation is when local motions aggregate to become a single subject [Nicholas of Autrecourt]
     Full Idea: In the case of natural things there is only local motion. When from such motion there follows an aggregation of natural bodies that are gathered to one another and acquire the nature of a single subject, this is called generation.
     From: Nicholas of Autrecourt (Tractatus [1335], Ch. 1)
     A reaction: This is explosive atomistic corpuscularianism, three centuries before its appointed date. He was duly suppressed. Can he give an account of the 'nature of a single subject' in this way?
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius]
     Full Idea: Archelaus was the first person to say that the universe is boundless.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
Causes can be inferred from perfect knowledge of their effects [Leibniz]
     Full Idea: Whoever understands some effect perfectly will also arrive at the knowledge of its cause.
     From: Gottfried Leibniz (Meditatio de principio individui [1676], A6.3.490), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2
     A reaction: This sounds highly improbable, given that you would have thought that there could be lots of ways to bring about the same effect. Predicting effects is rather more plausible. I suppose if you can record all the ripples in the pond before they fade...
27. Natural Reality / G. Biology / 3. Evolution
Archelaus said life began in a primeval slime [Archelaus, by Schofield]
     Full Idea: Archelaus wrote that life on Earth began in a primeval slime.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus
     A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea.
