5697 | The only possible standard for settling doubts is the foundation of the senses [Lucretius] |
Full Idea: If a belief resting directly on the foundation of the senses is not valid, there will be no standard to which we can refer any doubt on obscure questions for rational confirmation. | |
From: Lucretius (On the Nature of the Universe [c.60 BCE], I.422) | |
A reaction: A classic statement of empiricist foundationalism. The Epicureans don't appear to have any time for a priori truths at all. I wonder if they settled mathematical disputes by counting objects and drawing diagrams? |
411 | If we succeed in speaking the truth, we cannot know we have done it [Xenophanes] |
Full Idea: No man has seen certain truth, and no man will ever know about the gods and other things I mentioned; for if he succeeds in saying what is fully true, he himself is unaware of it; opinion is fixed by fate on all things. | |
From: Xenophanes (fragments/reports [c.530 BCE], B34), quoted by Sextus Empiricus - Against the Professors (six books) 7.49.4 |
5727 | Most supposed delusions of the senses are really misinterpretations by the mind [Lucretius] |
Full Idea: Paradoxical experiences (such a dreams and illusions) cannot shake our faith in the senses. Most of the illusion is due to the mental assumptions we ourselves superimpose, so that things not perceived by the senses pass for perceptions. | |
From: Lucretius (On the Nature of the Universe [c.60 BCE], IV.462) | |
A reaction: Some misinterpretations of the senses, such as thinking a square tower round, are the result of foolish lack of judgement, but actual delusions within the senses, such as a ringing in the ears, or a pain in a amputated leg, seem like real sense failures. |
412 | If God had not created honey, men would say figs are sweeter [Xenophanes] |
Full Idea: If God had not created yellow honey, men would say that figs were sweeter. | |
From: Xenophanes (fragments/reports [c.530 BCE], B38), quoted by Herodian - On Peculiar Speech 41.5 |
