2614 | Modern phenomenalism holds that objects are logical constructions out of sense-data [Ayer] |
Full Idea: Nowadays phenomenalism is held to be a theory of perception which says that physical objects are logical constructions out of sense-data. | |
From: A.J. Ayer (Phenomenalism [1947], §1) |
2615 | The concept of sense-data allows us to discuss appearances without worrying about reality [Ayer] |
Full Idea: The introduction of the term 'sense-datum' is a means of referring to appearances without prejudging the question of what it is, if anything, that they are appearances of. | |
From: A.J. Ayer (Phenomenalism [1947], §1) |
6866 | It is disturbing if we become unreal when we die, but if time is unreal, then we remain real after death [Le Poidevin] |
Full Idea: For the A-theorists called 'presentists' the past is as unreal as the future, and reality leaves us behind once we die, which is disturbing; but B-theorists, who see time as unreal, say we are just as real after our deaths as we were beforehand. | |
From: Robin Le Poidevin (Interview with Baggini and Stangroom [2001], p.174) | |
A reaction: See Idea 6865 for A and B theories. I wonder if this problem is only superficially 'disturbing'. Becoming unreal may sound more drastic than becoming dead, but they both sound pretty terminal to me. |
22395 | 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. |
6867 | Existentialism focuses on freedom and self-making, and insertion into the world [Le Poidevin] |
Full Idea: I take existentialism to be the focus on the freedom and self-making of the human being, and his or her insertion into the world. | |
From: Robin Le Poidevin (Interview with Baggini and Stangroom [2001], p.222) | |
A reaction: I take 'self-making' to be the key here. If neuroscientists somehow 'proved' that there was no free will, I don't see that making any difference to existentialism. 'Insertion' seems odd, unless it refers to growing up. |
6865 | A-theory says past, present, future and flow exist; B-theory says this just reports our perspective [Le Poidevin] |
Full Idea: The A-theory regards our intuitive distinction of time into past, present and future as objective, and takes seriously the idea that time flows; the B-theory says this just reflects our perspective, like the spatial distinction between here and there. | |
From: Robin Le Poidevin (Interview with Baggini and Stangroom [2001], p.174) | |
A reaction: The distinction comes from McTaggart. Physics seems to be built on an objective view of time, and yet Einstein makes time relative. What possible evidence could decide between the two theories? |
