4 ideas

14. Science / C. Induction / 3. Limits of Induction
From the fact that some men die, we cannot infer that they all do [Philodemus]
     Full Idea: There is no necessary inference, from the fact that men familiar to us die when pierced through the heart, that all men do.
     From: Philodemus (On Signs (damaged) [c.50 BCE], 1.3)
     A reaction: This is scepticism about the logic of induction, long before David Hume. This is said to be a Stoic argument against Epicureans - though on the whole Stoics are not keen on scepticism.
23. Ethics / D. Deontological Ethics / 4. Categorical Imperative
Moral judgements are hypothetical, because they depend on interests and desires [Foot]
     Full Idea: Moral judgements are hypothetical imperatives in the sense that they give reasons for acting only in conjunction with interests and desires.
     From: Philippa Foot (Reply to Professor Frankena [1975], p.177)
     A reaction: This is a splendid claim, which points to a more sensibly naturalistic ethics. There seem to be occasions for moral behaviour where I have no interests or desires, such as when a stranger asks me for a favour and I'm feeling tired.
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
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.
