5 ideas
| 13099 | Analysing right down to primitive concepts seems beyond our powers [Leibniz] |
| Full Idea: An analysis of concepts such that we can reach primitive concepts...does not seem to be within human power. | |
| From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], C513-14), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz | |
| A reaction: Leibniz is nevertheless fully committed, I think, to the existence of such primitives, and is in the grip of the rationalist dream that thoughts can become completely clear, and completely well-founded. |
| 21960 | Ordinary language is the beginning of philosophy, but there is much more to it [Austin,JL] |
| Full Idea: Ordinary language is not the last word: in principle it can everywhere be supplemented and improved upon and superseded. Only remember, it is the first word. | |
| From: J.L. Austin (A Plea for Excuses [1956], p.185), quoted by A.W. Moore - The Evolution of Modern Metaphysics Intro | |
| A reaction: To claim anything more would be absurd. The point is that this remark comes from the high priest of ordinary language philosophy. |
| 5022 | We hold a proposition true if we are ready to follow it, and can't see any objections [Leibniz] |
| Full Idea: A proposition is held to be true by us when our mind is ready to follow it and no reason for doubting it can be found. | |
| From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], p.7) | |
| A reaction: This follows on from Descartes' view, but it now sounds more like psychology than metaphysics. Clearly a false proposition could fit this desciption. Personally I follow propositions to which I can see no objection, without actually holding them true. |
| 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. |
