12. Knowledge Sources / B. Perception / 4. Sense Data / b. Nature of sense-data
Sensations are mental, but sense-data could be mind-independent [Vesey]
     Full Idea: Whereas a sensation is by definition mental, a sense-datum might be mind-independent.
     From: Godfrey Vesey (Collins Dictionary of Philosophy [1990], p.266)
     A reaction: This seems to be what Russell is getting at in 1912, as he clearly separates sense-data from sensations. Discussions of sense-data always assume they are mental, which may make them redundant - but so might making them physical.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Reliabilist knowledge is evidence based belief, with high conditional probability [Comesaņa]
     Full Idea: The best definition of reliabilism seems to be: the agent has evidence, and bases the belief on the evidence, and the actual conditional reliability of the belief on the evidence is high enough.
     From: Juan Comesaņa (Reliabilism [2011], 4.4)
     A reaction: This is Comesaņa's own theory, derived from Alston 1998, and based on conditional probabilities.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / b. Anti-reliabilism
In a sceptical scenario belief formation is unreliable, so no beliefs at all are justified? [Comesaņa]
     Full Idea: If the processes of belief-formation are unreliable (perhaps in a sceptical scenario), then reliabilism has the consequence that those victims can never have justified beliefs (which Sosa calls the 'new evil demon problem').
     From: Juan Comesaņa (Reliabilism [2011], 4.1)
     A reaction: That may be the right outcome. Could you have mathematical knowledge in a sceptical scenario? But that would be different processes. If I might be a brain in a vat, then it's true that I have no perceptual knowledge.
How do we decide which exact process is the one that needs to be reliable? [Comesaņa]
     Full Idea: The reliabilist has the problem of finding a principled way of selecting, for each token-process of belief formation, the type whose reliability ratio must be high enough for the belief to be justified.
     From: Juan Comesaņa (Reliabilism [2011], 4.3)
     A reaction: The question is which exact process I am employing for some visual knowledge (and how the process should be described). Seeing, staring, squinting, glancing.... This seems to be called the 'generality problem'.
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.
