2069 | Thought must grasp being itself before truth becomes possible [Plato] |

14794 | Instead of seeking Truth, we should seek belief that is beyond doubt [Peirce] |
Full Idea: Your problems would be greatly simplified, if, instead of saying that you want to know the Truth, you were simply to say that you want to attain a state of belief unassailable beyond doubt. | |
From: Charles Sanders Peirce (Essentials of Pragmatism [1905], I) | |
A reaction: This is not the same as saying that belief beyond doubt IS truth. He is merely offering a strategy for scientists to side-step the sort of scepticism raised by Descartes and radical empiricists. |
