10 ideas
| 12544 | Our knowledge falls short of the extent of our own ideas [Locke] |
| Full Idea: The extent of our knowledge comes not only short of the reality of things, but even of the extent of our own ideas. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.03.06) | |
| A reaction: The point is that we may be unable to find the links which make the connections. Which implies that there are real connections waiting to be found. We could call this 'conceptual realism'. A job for philosophers! |
| 6940 | The feeling of belief shows a habit which will determine our actions [Peirce] |
| Full Idea: The feeling of believing is a more or less sure indication of there being established in our nature some habit which will determine our actions. Doubt never has such an effect. | |
| From: Charles Sanders Peirce (The Fixation of Belief [1877], p.10) | |
| A reaction: It is one thing to assert this fairly accurate observation, and another to assert that this is the essence or definition of a belief. Perhaps it is the purpose of belief, without being the phenomenological essence of it. We act in states of uncertainty. |
| 6941 | We are entirely satisfied with a firm belief, even if it is false [Peirce] |
| Full Idea: As soon as a firm belief is reached we are entirely satisfied, whether the belief be true or false. | |
| From: Charles Sanders Peirce (The Fixation of Belief [1877], p.10) | |
| A reaction: This does not deny that the truth or falsehood of a belief is independent of whether we are satisfied with it. It is making a fair point, though, about why we believe things, and it can't be because of truth, because we don't know how to ensure that. |
| 6942 | We want true beliefs, but obviously we think our beliefs are true [Peirce] |
| Full Idea: We seek for a belief that we shall think to be true; but we think each one of our beliefs to be true, and, indeed, it is mere tautology to say so. | |
| From: Charles Sanders Peirce (The Fixation of Belief [1877], p.11) | |
| A reaction: If, as I do, you like to define belief as 'commitment to truth', Peirce makes a rather startling observation. You are rendered unable to ask whether your beliefs are true, because you have defined them as true. Nice point… |
| 6943 | A mere question does not stimulate a struggle for belief; there must be a real doubt [Peirce] |
| Full Idea: The mere putting of a proposition into the interrogative form does not stimulate the mind to any struggle after belief; there must be a real and living doubt. | |
| From: Charles Sanders Peirce (The Fixation of Belief [1877], p.11) | |
| A reaction: This the attractive aspect of Peirce's pragmatism, that he is always focusing on real life rather than abstract theory or pure logic. |
| 12574 | When two ideas agree in my mind, I cannot refuse to see and know it [Locke] |
| Full Idea: When the agreement of any two ideas appears to our minds, I can no more refuse to perceive, no more avoid knowing it, than I can avoid seeing those objects which I turn my eyes to. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.20.16) | |
| A reaction: Note that he is not just saying that we cannot resist believing what becomes evident to us, but he actually asserts that we cannot avoid 'knowing' it. This seems to imply that knowledge may be more basic than belief (as Williamson and Hossack argue). |
| 15995 | The greatest certainty is knowing our own ideas, and that two ideas are different [Locke] |
| Full Idea: A man cannot conceive himself capable of a greater certainty, than to know that any idea in his mind is such as he perceives it to be; and that two ideas wherein he perceives a difference, are different, and not precisely the same. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.02.01) | |
| A reaction: That leaves open the question of what you know when you know your ideas. Do you fully know the contents? The contingent truths expressed by some of them? Or just their meanings? |
| 12562 | General certainty is only found in ideas [Locke] |
| Full Idea: General certainty is never to be found but in our ideas. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.06.16) | |
| A reaction: This is a fairly standard empirical view of such things. The obvious opposition to it might be Moore's 'hand' example (Idea 6349), if we ask, which is more certain, this hand I hold up, or this complex proof in mathematics? |
| 12569 | Knowledge by senses is less certain than that by intuition or reason, but it is still knowledge [Locke] |
| Full Idea: The notice we have by our senses of the existing of things without us, thought it be no altogether so certain as our intuitive knowledge or the deductions of our reason, ..yet it is an assurance that deserves the name of knowledge. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.11.03) | |
| A reaction: This is a clear instance of an acceptance of fallibilism. So one would hope, I think, from an orthodox empiricist philosopher, especially a representative realist like Locke, who as lots of areas where doubts can creep in. |
| 12564 | I am as certain of the thing doubting, as I am of the doubt [Locke] |
| Full Idea: If I know I doubt, I have as certain a perception of the existence of the thing doubting, as of that thought which I call doubt. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.09.03) | |
| A reaction: The challenge to this Lockean assertion of the Cogito is what he means by a 'thing', and what grounds he has for asserting the existence of the 'thing', as opposed to some vague assertion about whatever makes doubting possible. |
