11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Perception is existence for my table, but also possible perception, by me or a spirit [Berkeley]
     Full Idea: The table I write on I say exists, that is, I see and feel it; and if I were out of my study I should say it existed - meaning thereby that if I was in my study I might perceive it, or that some other spirit actually does perceive it.
     From: George Berkeley (The Principles of Human Knowledge [1710], §3)
     A reaction: Berkeley is always (understandably) labelled as an 'idealist', but this seems to be what we call 'phenomenalism', because it allows possible experiences as well as actual ones. See Ideas 5170 and 6522.
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / c. Empirical idealism
The only substance is spirit, or that which perceives [Berkeley]
     Full Idea: It is evident that there is not any other Substance than spirit, or that which perceives.
     From: George Berkeley (The Principles of Human Knowledge [1710], §7)
     A reaction: Weird. To say that this is 'evident' seems to be begging the question. Why should he assume that there is nothing more to reality than his perception of it? He seems strangely unimaginative.
The 'esse' of objects is 'percipi', and they can only exist in minds [Berkeley]
     Full Idea: The absolute existence of unthinking things with no relation to their being perceived is unintelligible to me; their 'esse' is 'percipi', nor is it possible they should have any existence out of the minds or thinking things which perceive them.
     From: George Berkeley (The Principles of Human Knowledge [1710], §3)
     A reaction: "Esse est percipi" (to be is to be perceived) is the well-known slogan associated with Berkeley. I cannot see how Berkeley can assert that the separate existence of things is impossible. He is the classic confuser of epistemology and ontology.
When I shut my eyes, the things I saw may still exist, but in another mind [Berkeley]
     Full Idea: When I shut my eyes, the things I saw may still exist, but it must be in another mind.
     From: George Berkeley (The Principles of Human Knowledge [1710], §90)
     A reaction: This strikes me as ridiculous. What kind of theory says that a table goes out of existence when someone forgets to look at it for a moment, but is then recreated in identical form? Epistemology is not ontology.
