18033 | The meaning of a representation is its role in thought, perception or decisions [Block] |
Full Idea: According to conceptual role semantics, the meaning of a representation is the role of that representation in the cognitive life of the agent, for example, in perception, thought and decision-making. | |
From: Ned Block (Semantics, Conceptual Role [1998]) | |
A reaction: I never believe theories of this kind, because I always find myself asking 'what is the nature of this representation which enables it to play this role?'. |
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 |
20919 | How can things without weight compose weight? [Alexander] |
Full Idea: How could weight come about out of things composed of what is without weight? | |
From: Alexander (On Aristotle's Metaphysics Book 2 [c.200], p.36.21-27) | |
A reaction: This is obviously why Epicurus added weight to the features of atoms. Alexander seems unaware of this move. |
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. |
