6 ideas
| 12583 | Belief truth-conditions are normal circumstances where the belief is supposed to occur [Papineau] |
| Full Idea: The truth condition of the belief is the 'normal' circumstances in which, given the learning process, it is biologically supposed to be present. | |
| From: David Papineau (Reality and Representation [1987], p.67), quoted by Christopher Peacocke - A Study of Concepts 5.2 | |
| A reaction: How do we account for a belief in ghosts in this story? The notion of 'normal' circumstances and what is 'biologically supposed' to happen don't seem very appropriate. This is the 'teleological' view of belief. |
| 2602 | What experience could prove 'If a=c and b=c then a=b'? [Descartes] |
| Full Idea: Please tell me what the corporeal motion is that is capable of forming some common notion to the effect that 'things which are equal to a third thing are equal to each other'. | |
| From: René Descartes (Comments on a Certain Broadsheet [1644], p.366) |
| 2600 | The mind's innate ideas are part of its capacity for thought [Descartes] |
| Full Idea: I have never written or taken the view that the mind requires innate ideas which are something distinct from its own faculty of thinking. | |
| From: René Descartes (Comments on a Certain Broadsheet [1644], p.365) |
| 2601 | Qualia must be innate, because physical motions do not contain them [Descartes] |
| Full Idea: The ideas of pains, colours, sounds etc. must be all the more innate if, on the occasion of certain corporeal motions, our mind is to be capable of representing them to itself, for there is no similarity between these ideas and the corporeal motions. | |
| From: René Descartes (Comments on a Certain Broadsheet [1644], p.365) | |
| A reaction: Simple and brilliant! We know perfectly well that there is no redness zooming through the air from a tomato (or the air would be pink!). Redness occurs when the light arrives, so we add the redness, so it is innate. |
| 1748 | 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 |
| 5989 | 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. |
