| 6937 | Reason aims to discover the unknown by thinking about the known [Peirce] |
| Full Idea: The object of reasoning is to find out, from the consideration of what we already know, something else which we do not know. | |
| From: Charles Sanders Peirce (The Fixation of Belief [1877], p. 7) | |
| A reaction: I defy anyone to come up with a better definition of reasoning than that. The emphasis is on knowledge rather than truth, which you would expect from a pragmatist. …Actually the definition doesn't cover conditional reasoning terribly well. |
| 19807 | Both nature and reason require that everything has a cause [Rousseau] |
| Full Idea: Under the law of reason nothing takes place without a cause, any more than under the law of nature. | |
| From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.04) | |
| A reaction: Is this the influence of Leibniz? Note that the principle is identified in two different areas, so in nature we may say 'everything has a cause', and in rationality we may say 'there is a reason for everything'. But are these the same? |
