20947 | Thoughts are learnt through words, so language shows the limits and shape of our knowledge [Herder] |
Full Idea: If it is true that we cannot think without thoughts, and that we learn to think through words: then language gives the whole of human knowledge its limits and outline. | |
From: Johann Gottfried Herder (On Recent German Literature. Fragments [1767], p.373), quoted by Andrew Bowie - Introduction to German Philosophy | |
A reaction: Deomonstrating that Frege's famous 1884 'linguistic turn', immortalised by Dummett, was actually the continuation of a long focus on language in German philosophy. Non-verbal animals very obviously think. |
14779 | I reason in order to avoid disappointment and surprise [Peirce] |
Full Idea: I do not reason for the sake of my delight in reasoning, but solely to avoid disappointment and surprise. | |
From: Charles Sanders Peirce (Criterion of Validity in Reasoning [1903], I) | |
A reaction: Hence Peirce places more emphasis on inductive and abductive reasoning than on deductive reasoning. I have to agree with him. Anyone account of why we reason must have an evolutionary framework. What advantage does reason bestow? It concerns the future. |
14777 | That a judgement is true and that we judge it true are quite different things [Peirce] |
Full Idea: Either J and the judgment 'I say that J is true' are the same for all judgments or for none. But if identical, their denials are identical. These are 'J is not true' and 'I do not say that J is true', which are different. No judgment judges itself true. | |
From: Charles Sanders Peirce (Criterion of Validity in Reasoning [1903], I) | |
A reaction: If you are going to espouse the Ramseyan redundancy view of truth, you had better make sure you are not guilty of the error which Peirce identifies here. |
14780 | Only study logic if you think your own reasoning is deficient [Peirce] |
Full Idea: It is foolish to study logic unless one is persuaded that one's own reasonings are more or less bad. | |
From: Charles Sanders Peirce (Criterion of Validity in Reasoning [1903], II) |
14778 | Facts are hard unmoved things, unaffected by what people may think of them [Peirce] |
Full Idea: Facts are hard things which do not consist in my thinking so and so, but stand unmoved by whatever you or I or any man or generations of men may opine about them. | |
From: Charles Sanders Peirce (Criterion of Validity in Reasoning [1903], I) | |
A reaction: This is my view of facts, with which I am perfectly happy, for all the difficulties involved in individuating facts, and in disentangling them from our own modes of thought and expression. Let us try to establish the facts. |
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. |
