| 7803 | Modal logic began with translation difficulties for 'If...then' [Lewis,CI, by Girle] |
| Full Idea: C.I.Lewis began his groundbreaking work in modal logic because he was concerned about the unreliability of the material conditional as a translation of 'If ... then' conditionals. | |
| From: report of C.I. Lewis (Symbolic Logic (with Langford) [1932]) by Rod Girle - Modal Logics and Philosophy 12.3 | |
| A reaction: Compare 'if this is square then it has four corners' with 'if it rains then our afternoon is ruined'. Different modalities seem to be involved. We even find that 'a square has four corners' will be materially implied if it rains! |
| 22086 | The most important aspect of a human being is not reason, but passion [Kierkegaard, by Carlisle] |
| Full Idea: Kierkegaard insisted that the most important aspect of a human being is not reason, but passion. | |
| From: report of Søren Kierkegaard (works [1845]) by Clare Carlisle - Kierkegaard: a guide for the perplexed Intro | |
| A reaction: Hume comes to mind for a similar view, but in character Hume was far more rational than Kierkegaard. |
| 7469 | There is no hereafter in the Book of Job [Anon (Job), by Watson] |
| Full Idea: The entire Book of Job is concerned with faith and suffering and inequality in a life where there is no hereafter (all the rewards promised to the Jews by their God are worldly). | |
| From: report of Anon (Job) (18: Book of Job [c.535 BCE]) by Peter Watson - Ideas Ch.5 | |
| A reaction: It is extraordinary how such ideas can creep into the great religions, and then become taken for granted, as if no one had ever doubted them. |
